Mazda - B4000 :: 2000 - Take Time To Turn Over?
Feb 11, 2013
I have a 2000 Mazda B4000 with 2 little problems I don't know anything about. First is when I go to start the truck it takes a long time to turn over. A friend of mine said that a valve is not maintaining fuel pressure so the fuel is not sitting ready for the starter when I go to start up. But if i engage the key for a few seconds and time it right it will turn over easily (apparently allowing the fuel pressure to build to the appropriate level). Is this a little valve or gasket or something I can replace to maintain the pressure?
Second, when I'm coming from a stop or accelerating out of a slow roll there is a 'shudder' or 'shiver' in the drivetrain that almost feels like the shift from 1st to 2nd is just kinda lumpy. It also happens if I come to an abrupt stop, so gearing down into 1st. It doesn't feel like something that is getting worse, but I don't want it to be causing damage or have my driveshaft snap or something.Other than that this truck seems really well maintained by the previous owner, and a mechanically inclined friend of mine said everything else looks.

After having my whole clutch system replaced..the truck now hesitates after 25mph shift 35, 45 and so, on it does not have a rough idle, it is like it has a hard time going then gets a burst of gas or air or will power and runs great till the next shift..,after replacing air filter, fuel filter. fuel pump & regulator, tps sensor co2 sensors and cleaning maf/map and fuel injectors, is using lots of gas too..the truck is still not happy, spent hours checking for pinched vacuum or fuel or eclectically lines.. Oddest thing, it won't throw any codes.. 1994 mazda b4000...

I've traced a 0.3-amp parasitic drain to the audio power amp (fuse #16, 20A). Pulling the fuse, the radio still works (it's on fuse #15) but then there's no sound from the speakers. (There's also no current drain. I'm weighing if it's more important for the truck to run or to sound good.)
I replaced the radio a month ago. It was definitely not working right, and the new radio definitely is. With the #16 fuse in place, the sound out of front and back speakers was great. "Was" because if I leave the fuse in, the battery gets drained in a few days, so the fuse is now out.
Where the audio amp is. My Haynes manual doesn't say. The amp has no user controls. It just takes the radio's output and feeds audio to the front and back speakers. The #16 fuse is what gives the amp power. Some online posts say it's under the glove box, some say behind the rear right speaker. All agree it's a bear to access.
So a few questions:
Why the power amp would be drawing current even when the truck and radio are powered off?
How does one troubleshoot this, short of replacing the power amp, which of course I don't have an extra lying around and wouldn't want to replace anyway as it's otherwise working great.
What do you think of installing a switch on the audio power amp circuit so that when the truck is parked, I switch it off, and no current drain, but when the truck is driven, I switch it on, letting me hear the radio or CD. This is obviously a kludge/ghetto solution, but the advantage is that I don't have to access or replace the audio amp. I want to keep using the fuse, of course, so am looking for a way to wire a switch into the fuse box while keeping the fuse in the circuit. If I knew which wire goes between the fuse and the audio amp, I'd splice a switch there, but I don't, and again, the Haynes manual is not useful.

So i just bought a b4000 pickup 5spd .. Anyway the truck has eletrical 4x4 with manual hubs. When i turn the switch nothing happens. The 4wd/4wd low lights both flash 6x then go off then flash again while running , driving, koeo, anytime like an obd1 check engine light code flashing. Anyway i checked the wiring for the 4wd switch no power, went to the fuse interior no pwr, went to the engine fuse box power. You don't hear the transfer case engage at all as well.

So Im working on a 1998 mazda b4000, frost plug blew out going down the highway changed the engine because it got cooked pretty bad. The wrecker engine I got for what ever reason will only run good if the driver side of coil pack is done 5,6,4 any other order truck wont run at all. Misses enough to shake the truck at around 80 km/hr otherwise its pretty good. Also the engine I got came factory with no egr.... no provisions nothing. exhaust manifold capped off, seemed kinda odd.

Over the past year we have been noticing that the HVAC blower doesn't turn on from time to time. All settings in the control panel seem normal and the fan speed is turned on. Most of the time everything is working normally, sometimes when the car starts the blower isn't working and then starts after a minute of driving. Sometimes I notice the blower isn't working and I turn up the fan speed and after a few clicks it starts working normally for the remainder of the drive. And then sometimes the blower doesn't ever start and I need to turn off and restart the car a few times. When the blower hasn't been working the a/c compressor has been turning on, something in the blower circuit is failing.
There are five possibilities:
The HVAC controller isn't telling the blower to turn on
The power relay isn't always working
There is a wiring or connection problem
The blower motor itself isn't working
The power mosfet is failing.
What needed to be replaced?

I have a 2003 Mazda 6. Almost every day, after starting it and driving maybe .10 of a mile, it seems as my car shifts, it shifts really hard, like a thump. I am thinking of having the Transmission serviced. Is this worth it? About what should the cost be? What do they do, just drain the fluid and add new?

I have a 1995 Mazda Truck, B2300 series that is a 4 wheel drive. Recently I had the front brakes replaced, new clay disc brakes. Not so long after that I started to hear a noise as I was braking as well as squeaking. I thought, of course it had something to do with the new brakes. The sound happened occasionally at first and now is every time I brake.
I can hear it as I'm coming to a stop, sounding like it's coming from the rear. It's a rubbing type noise, like a wa, wa, wa, wa that happens until I have stopped. After 2 mechanics I now have a $700 estimate to replace the u-joint, and they aren't even sure if that will fix it.
The front brakes are new. The rear drums have been replaced and machined to fit properly (they thought that was the issue). Is this common or something that I have to fix every such and such miles?

Why my key would not turn in the starter, although an hour previously and up to yesterday it has always worked just fine. Again, this morning, the key turned just fine. Is this a warning that I'm heading towards disaster?

I have an '87 Mazda B-2000 pickup. How to turn off the EGR light? I think it comes on at set intervals when it wants you to check the EGR system.

My 94 B4000 (4.0L ohv)is acting weird. If I let it sit for more than a day, it won't start. I pop the intake tube off, squirt some gas in the plenum, and away she goes. It starts all day long after that. I can hear the fuel pump running. Is there a possibility there is a fuel pressure regulator leaking down, kinda like a pump losing it's prime? Or am I looking at dropping the tank for a new fuel pump??? It's getting close to winter up here (gonna snow anytime) and I don't need this kind of trouble when it's cold and snowy.

As the title states, I have a 2002 Mazda B3000 series Pickup and while everything is working great, the a/c is driving me insane!
Here's how it goes:
- Start the car, turn on the A/C, hear a click
- As I drive, after 10-20 minutes, the A/C would just either switch to (what I think is) vent; it blows humid, warm air.
- Another way to turn it off is to accelerate quickly; Note: these two scenarios are sometimes inconsistent
- Sometimes, it would occur, while other times it would just randomly turn itself off
- A solution I've found is to switch over to vent, leave it on there for a few minutes, then switch back to A/C; works for another 10-20 minutes
What I have done to fix it is to replace the freon (even though, it was never really empty; still isn't empty) and have replaced the fuse associated with the A/C.

My son's mazda 6 will turn over but not start. the things I have done:
1. replace crank sensor
2. replace cam shaft sensors
3. it has spark
4. fuel pump works
5. sprayed starting fluid in still will not start.
What else should I check? Security system?

I have a 2003 Mazda B2300 pickup that sometimes won't start. When you turn the key all the way, it won't do anything, no sounds no nothing. However, if you try it a few more times it will eventually fire up and run normally. Last Friday, I must have tried to turn it on about a dozen times but nothing happened. So I tried the old hammer on the starter motor technique and it fired up immediately.
So I thought it must be the starter motor. But since then it's been turning on normally, except once when I turned the key and it did nothing. The battery is good, I replaced that about 8 months ago, and the battery cables look good. I'm hesitant to throw a new starter in. Could it be something cheaper, like a relay or some other electrical problem? Or could it be the starter and its on its way out?

This interference correlates directly to tire rotation speed, engine rpm has no effect. Under about 5mph it won't make the noise, but over that you hear a pop more or less for every rotation of the tire and when you hit say 50mph it is just a steady static noise on AM only. Haven't pulled the head unit yet, checked several body grounds under the hood and all are good. Don't know if a damaged wheel sensor could cause an issue or not.

My 2002 Mazda MPV will stall everytime after the rpms go over 2,000 and I let off the gas. I can put it in neutral and it will start back up. Not sure if something is clogged or its electrical? It has 177,000

I have a 2000 Mazda Protoge. I recently had the air conditioning fixed and primarily afterwards (although it could have been quiet before), when I accelerate or perhaps when it is thinking about shifting gears, I hear a strange buzzing sound, like a fan is hitting a bit of metal or something. It isn't too severe, but it sounds like it might be getting a little worse. Not louder, just more often. Belt? Two things touching? Should I bring my car, or is this just growing pains?

My Mazda MPV (2000) won't start. The dashboard lights work and the headlights work so the battery is okay, but when I try and start the engine it won't even crank.
The problem might be that last night I pulled the key out while it was on 'drive' but i was able to start it after and put it back into park. This morning though it won't even start.
Some things i noticed that may or may not be related are that the brakes pedal is very stiff, also when i press on the brakes it makes a clicking noise in the ignition, and the steering wheel is very stiff even when the key is turned to ACC. Is it permanently stuck in anti-theft or something?

I have a 2000 Mazda 626, V6, 5-speed with 157,000 miles. The car cuts out (as if it's loosing fuel) and stalls intermittently. This has been happening for 3-4 weeks and neither my regular mechanic nor the Mazda dealer can figure out what's wrong. Here's what they've tried: new fuel pump (replaced 3 times to make sure parts not faulty), new wires and plugs, new alternator belt, replaced fuel pressure regulator, replaced mass air sensor, cleaned/checked fuel & air filters, replaced coil/distributor (2 times to make sure part not faulty), checked for vacuum leaks, checked ignition/sensors (CAM and others).
It has been stalling intermittently for 3-4 weeks, though for a while would not do it when with the mechanic. Also, the check engine light would never come on, so there were no codes to check into. Sometimes after it would stall, it would not start up again until the engine was cold. Recently, it stalled when the mechanic was test driving it. He pulled off the mass air sensor and it started right up. He replaced that part and the car was driving OK for several days. I even took it on a couple 2.5 hour round trips. Today, however, I could not get it started. It would turn over, but not fire and it seems to me that it wasn't getting enough fuel.

I have a 2000 Mazda Protege ES (1.8L) with 120k+ miles and an automatic transmission. The car drives well at speed, but when sitting at stops it will shake a little, sometimes worse than others. Often the RPMs drop to below the lowest tick for a split second before recovering, very much like when driving a manual transmission and not pressing the clutch in enough. Even when the RPMs are steady at a stop, it shakes enough to rattle a couple of the plastic parts in the dashboard.
Recent history (some likely unrelated, but I'm no expert):New air hose (one from the air filter to the engine) in September. RPMs were falling at idle more often than they are now, there was a decent sized crack in the hose. RPMs stopped falling as often, but has idled roughly before and after.New radiator and thermostat in April (overheated on the interstate and cracked open).New spark plugs and wires last fall after one cylinder wasn't firing.For the last couple years every fall when it starts to get cold, the alternator belt squeaks and I tighten the bolt a little each morning until it stops (usually after 2 days, maybe 3 - the alternator itself is on a long bolt that adjusts the belt tension).Every 5k miles I have the oil changed with high mileage oil and tires rotated/balanced.
I took it to a garage a couple weekends ago after the check engine light had come on earlier in the week. I reset the computer and the light never came back on, so I lost the chance to have the code read, but there weren't any other symptoms beyond what I'm used to. The mechanics at the shop said they couldn't find anything specific causing the rough idle and suggested replacing some or all of the motor mounts, which are weak. They didn't seem confident that would fix the problem, and neither am I, as I don't see how weak motor mounts would explain the low RPMs as well as the shaking.
