Passat (B5) :: 1998 1.8t Died And Now Cranks But Won't Start
Feb 7, 2012
I've been fighting several problems with this car (1998 1.8t aeb 5 speed manual) I replaced the icm and coil packs just recently to fix an ignition problem. At least i thought the problem was fixed. Car was running good but still had an occasional loss of power and bucking.
Today I installed a new fuel filter and went for a drive to see if that fixed the problem. I get about a mile from my house and the car died at a stop sign. I tried several times to start it back up and nothing. I pushed it off to the side and left it there for the night, I'll go back in the morning to try to trouble shoot it.
Symptoms: I noticed that when I turned the key to the on position, the fuel pump relay would click and doesn't stop unless i turn the ignition off. The throttle body is also actuating at the same time, idle stabilizer? But its doing this with the engine off and key in on position. Also there is fuel pressure at the rail.
What would cause this? My only thought would be a failed ecu or possibly fuel pump relay (though I don't see how that would effect the throttle body).

My 4.2L died all of a sudden, it cranks but won't start. Checked the harness side to coil packs, pos. signal but no neg. Tried a code reader keeps coming back link error. Does this mean PCM is fried?

95 850 died on the highway - now it cranks and won't start. I had it towed to a mechanic who later told me he didn't work on Volvos. He did however check for spark - good. Timing belt- good. I replaced fuel pump and relay - no go. One possible hint is the lights on the Sport/Econ switch no longer light up and the first light I saw when it died was the up arrow light on the dash. Last winter I cleaned and regreased the PNP switch. Would that have anything to do with it?.

Ok, so I ran my car battery COMPLETELY dead the other day. After replacing the battery and checking to ensure that it had sufficient power, i tried starting it. It cranks over very solid, but will not start. I sent it to the dealer, and their diagnostic tools receive question marks back from all the modules. This has led us to the conclusion that my ECU (ECM) needs to be reset, or has malfunctioned in some way. There is an aftermarket flash on the ECU, but I do not know by which company as it was flashed when I bought the car. How can I do a hard reset on the ECU?

Car died at idle on park. Tried to start it back up and was only getting crank. I took it to a local mech and he said my timing belt failed. I paid for the repair and the car still wouldn't start. The shop said the ecu went out. I replaced the cam position sensor and main relay under the dash. Still not getting it to start. I also have a ecu from an 05 accent, would this be plug and play? What else can I do?

Went out to start my truck this morning and it wouldn't start. Cranks fine and almost started once but died. Checked all fuses all my voltages are good. Oil and coolant are good. When I turn the key on I can hear the fuel pump and sounds like it's priming correctly. Might be an issue with a clogged fuel filter? Maybe? Haven't had any problems or issues otherwise.

Engine cranks but will not start, it kicks back after cranking over for a couple of times i have replaced the crank sensor it has done this once before it kicked back hard enough to knock a tooth off of the flywheel after replacing flywheel and starter it started fine for three months then it kicked back hard enough to break a starter mounting bolt. i replaced bolt had starter checked and replaced again?

I've got a 1998 Jeep Cherokee Sport 4x4, 4.0 L I6, automatic, 169k miles, that often cranks but doesn't start up. When I cut the power and try again, it starts up right away. I'm concerned this workaround will one day not work and I'll be left stranded, so I'd like to fix this if it's cheap and easy. The symptoms suggest either a lack of fuel or lack of spark due to an electrical problem, so I replaced the ASD (auto shutdown) and Fuel Pump relays, but they made no difference. The other two relays - Starter and Cooling Fan - seemed irrelevant. What this could be? Maybe the crank angle sensor? (I'm not even sure where that's located.)

I have a 98 F150, 4.6L with approx. 245,000 miles on it. recently it started, then studdered a little bit and died. I managed to get it re-started, it then shuddered a little more although I was able to drive it back up the drive way and park it. Now, it will crank however it does not even attempt to fire. The sound that it makes when trying to start seems odd to me. Like the engine is just turning against a constant resistance instead of the normal starting sound. I tried shooting a little starter fluid into the throttle body and nothing changed. I pressed on the shrader valve and got a spew of fuel to come out so it seems that it might not be a fuel problem though it sure sounds like one. Just curious, what are the symptoms of a truck with no compression?

I have a 1998 Ford Explorer. It was running fine until last Mon. On my 3rd start of the day , it wouldn't stay started long enough to get into gear; sometimes it sputtered violently. I tried starting over the next 2 days with the same outcome so I towed it to mechanic. They replaced spark plugs, wires & started (because it was throw lower voltage than normal). It ran fine the short distance home. The next day, it started fine but sputtered in corners/lower speeds. About 12 miles into the drive, which was at ~60 mph, my auto died and wouldn't start again. What's going on? Could it be the fuel pump?

I'm a relatively new F150 owner (just got rid of the 98 Ranger I drove since 99), so I thought I'd check in to see if I was overlooking something obvious. A few days ago, after driving to the store with no obvious issues, I went shopping (coincidentally for oil change materials) and when I returned to my truck it would not start.
Here is a bit of info:
Starter cranks over the engine.
Battery is relatively new, and has plenty of power.
I can hear the fuel pump kick on briefly.
Check engine light is on (EGR Valve fault).
Engine started with starter fluid.
Engine ran like normal after starting.
Finally, the vehicle started/ran fine for a few days before the issue occurred again.
Like I said, I'm not too familiar with the vehicle yet, but I'm assuming the issue must be with the fuel delivery system. I plan on replacing the EGR valve, but I am curious whether a faulty EGR valve cause a no start? Also, I'm wondering if it's more likely that the fuel pump is going bad, or something electrical is the problem since I'm under the impression that the engine stops sending fuel to the cylinder if/when the engine doesn't start quickly after turning the key.

Made a trip to the hardware store yesterday. When I came out, the truck would crank just fine, but wouldn't start (98 4.0L 4x4). Tried adding gas, no luck. I had actually called a wrecker, but it eventually started after sitting for about an hour. All I did differently was hit the gas pedal a couple of times. Thinking it may be a low fuel pressure problem, I took it to autozone this morning (started it about 4 times now with no problems). Checked the fuel pressure, and it sat at a solid 65 lbs at idle. I tried holding the throttle open and it stayed at the same pressure. I forgot to try with the vacuum off.
First off, I've seen some people say 60 lbs is right, but more say it should be at about 45lbs. 45 seems right since the fuel return is on the block, not on the pump. I'm guessing the fuel damper went out, but is there any good way to check it? Also, since the damper is vacuum controlled, would a bad vacuum cause this problem? Third, could high fuel pressure cause it to not start? That's the one I'm most worried about what was wrong there.

We have a 2001 passat 1.8T It has had problems starting up for over 1 year. My wife drives the car so I only notice issues with it when we go together in her car. When I first noticed the problem, it was that it took a couple more cranks before it would start and didn't always happen. Now I notice that it won't start on the first try no matter how long it cranks, try again and it starts right up. The only thing I have not done as far as tuneup is the PCV valve that I have not figured out where it is.

First time ever, my Passat has stranded me. Won't start. 120K. Cranks fine. Fuel pump fuse is OK. Almost new plugs. New fuel filter. No codes. Almost a full tank of gas. No smell of fuel in engine compartment. Disconnect MAF, no difference. This started over a week ago. The car would not start on the first try. Always on the second try. Once started the car ran fine, did not stall or hesitate. Then, just once, it almost did not start; I think it was the fourth try it finally started. After that I replaced the fuel filter, just in case. It's been fine for several days. Now this morning, no go

When I turn the key to start the engine, it makes the sound (I don't know what to call it) that it makes before the engine actually starts but it just keeps doing that. The dash has the battery light on in red so I think that might be the problem. It also flashed "STOP" at me on the dash so I stopped fiddling with it.
The dealership is only a few blocks away but they are closed until tuesday. What is usually the problem in this case? I know almost nothing about how cars work.

My cousin has a 99 1.8T passat and its been sitting for a bit so initially I thought it was the battery but it is fine. The car cranks and it turns over but it will not start. It was fine than it was left for a few days when it was cold and has not started since.
I am not too farmiliar with the 1.8T .... I pulled out the dipstick and found the oil to be a little cloudy, that got me worried but last time it was driven the car was fine. It also looks kinda green but I am not sure if its the coolant since the coolant in the reservior is red or maybe orange.

I went to start my car this morning it cranks and nothing it is not firing at all, and I do not hear the fuel pump when I open the door like I usually do. It just happened all the sudden. Is there a way to check fuel pressure in these in the W8? Also any known problems to make them do this? So irritating...

I got a 05 Passat I am working on. The car was being drove and my customer when to eat lunch. Came out side and didn't start. Got it to my house threw it on the scanner and it brought up 2 cam sensor codes. Replaced them and still nothing. What to try next. The car cranks over fine and it does have fuel pressure and also has spark.

2001 passat, 1.8, manual 140K. Last Wednesday I went to drive south, and i turned the key. The engine cranked but it didn't start. After trying for a few minutes, and the engine stumbling after a few times, the engine started. RPMs were low, but after a few seconds everything was fine. The outside temp was probably 15-20f.
Over the next few days the car sat, except for once where I moved the car (outside temp was 35+), and it started right up. As soon as the temperature dropped to 18 or so, it did the same thing, crank and crank then start. I dont remember if it was then or wednesday when I got a CEL while trying to start the car. I checked it and got a P0321. Cleared it and havent seen it since.
Fast forward to sunday, morning was the same thing, about 10 tries until the engine started. I got a jump start in the afternoon thinking it was the battery. It started right up (temp was 30+?). The next day I decided to roll start it, started right up (temp was 15?).
I replaced the battery monday thinking that was the cause. But everything is the same, when its cold I have to crank and crank. Once the car is running, the RPMs are low. If I give it gas, it stalls. Once the RPMs come up, if I stop the engine, it starts right back up. Thinking it is a fuel problem, I played with the fuse.
Granted, the engine was warm when I did this. Engine running. Pull fuse out, after a few seconds engine stalls. Try to start, no go. Put fuse back in, engine starts right up on first try. So now we go back the CEL. I thought at first it was just a side effect of cranking and cranking the engine. But now I think there might be a problem with a sensor, engine speed sensor maybe? Coolant? crank?
