Golf IV / Jetta IV :: Car Won't Crank / Start - Faulty Fuel Pump
Dec 5, 2014
1999 Jetta 2.0L manual trans
One day out of the blue the car would not crank or start. Checked and found that fuse #14 was blown and would blow the instant another fuse was inserted. Checked all the typical locations for wiring issues usually associated with the comfort module because it had all the symptoms of a faulty module (the power windows did not work and the fuel pump didn't pressurize the system when the driver door was opened, the alarm didn't set, automatic door locks also inoperable).
I checked the dome light, trunk hinges, rubber boot between doors and body and found nothing. Put a jumper wire into the neutral start relay and was able to crank the car. I then replaced clutch safety switch, neutral start relay and installed new (junkyard) comfort module and the car cranked up, started and everything was working normally again...for about 3 weeks. Then it did the exact same thing again. Fuse #14 was blown again and would blow the new fuse as soon as it touched the terminals in the fuse box.
I reinstalled the jumper wire in the start relay in order to be able to drive the car for the last week, and then last night out of the blue the car would crank, but not start. I turned the engine over several times and could hear the fuel pump pumping and even smell fuel, but no start. 3-5 minutes later after random tries to start, the car stumbles to life as if it wasn't getting fuel, and then drove 10 miles home with no issues. I returned the 'faulty' comfort module Monday and got another one but haven't installed it yet because I fear the same thing happening with this one as the other one.
Last night after I got the car home, I plugged in the comfort module and everything worked like it was supposed to. Can a faulty fuel pump damage the control module? I'm trying to get to the bottom of this and fix the problem and not the symptoms so I'm looking into anything that could potentially cause the problem.

So, before we diagnose further, i have my fuse #43 pulled because that has been the only thing that somehow magically makes my car run when its not plugged in. I believe I've been dealing with a bad distributor and haven't come up with the funds yet to mod it for a v6 mustang coilpack.
BUT as the title describes, this just started happening today. The cluster wont turn on, fuel pump is cranking over, and the starter will whine as it cranks but no spark. Is the distributor getting that bad or am i looking at something worse?

R's at the dealer today for a faulty fuel float sensor, and they just called to let me know my vehicle has the wrong fuel pump in it. Seems mine has the pump for the Golf/Rabbit with the 4 cylinder engine and they need to keep the car until the part is in.

Its a 2005 awp 1.8t gti with 180K stage 2 apr. When i tune the key to the accessories on position I used to hear the fuel pump priming but now I don't and the car wont start.

2005 1.8t gti wont start. The other day I was driving on the highway when a thin plastic type wrapping got caught in my serpentine belt. The car immediately died and I hit the gas and nothing and with no power steering i pulled over to the side.
Timing belt was done with water pump and tensioners
Spark plugs and coils are brand new
What fuel line to disconnect to test if the fuel pump works? Like I said in the title I cant hear the fuel pump priming. The engine was running 100% before this 2 techs saw it and the vw dealer i workrd at looked it over.

vue would crank, not start. 5 min later it started. done this 3 times in 1 month. changed original fuel filter. am leaning towards fuel. vs spark. no codes. I see pump assy's for $175. or a pump alone for $30. if I remove tank and pump assy, would there be any issue with changing pump alone? not paying shop so its my effort the last gm pump assy I did had a working pump but corrosion on leads to pump inside tank. I replaced assy because I had already bought assy.

I know this has been an issue for awhile and many may know about it but many probably don't. The issue is dirt and salt debri etc get packed behind the Fuel pump driver module rot it out and without warning you have a crank no start or worse it dies going down the road then you and the family are stranded or worse while towing on a trip. I made a video on how it happens and how to fix it with the solution Ford came up with. It is worth checking even if you don't seem to be having any issues yet......

I have an 04 Ford Explorer XLT 4.0 Flex Fuel. There has been loss of power to fuel pump. Relay and fuse both good, replaced the inertia switch...still nothing. Could a FPDM (fuel pump driver module) have anything to do with this issue? Or what should I check next? I am definitely at a loss as to what the issue could be! I know it is fuel related because I used starting fluid and it started right up and run for just a few seconds, so that should rule out ignition I think.

Sometimes after running my 94 Limited, it doesn't want to start - it does crank - like it's not getting fuel. I have found the work around and want to know if it would be fixed by replacing the fuel pump relay.
The symptom is just after starting, it starts to run poorly, and then dies out, then will not start at all. I use to keep trying to start it for 20-40 minutes and suddenly it seemed to work.
It seems the work around is to turn the key to on for about 5 seconds and then turn it off - then it starts and runs as good as ever.
So, is this a symptom of a bad relay? I thought I'd start there because of the cost of the relay is fairly cheap. 1994 Explorer Limited 4x4?

I own a 2003 Limited with the 6.8 V10. I drove the truck on Sunday and all appeared to be fine, gas gauge was setting just under a half tank. When I went to start it yesterday, it would not start. Strong crank, no start. I checked my fuse and it was fine. Fast forward to this morning, since I had kind of depleted the battery with attempting to start, I put my little jump start pack on it and gave it a whirl. Truck started fine but the gas gauge was sitting on empty. I had five gallons of gas in the garage so I added that to the tank then drove to the local gas station to add more fuel. I put another 10 gallons in the tank so it should have roughly 16 or 17 gallons in the tank. Gauge shows 3/4 tank but miles to empty is right around 175 miles which would seem right with 17 gallons in the tank. I suspect the fuel pump. I don't really want to spend $500 on the Motorcraft unit but was wondering if the group believes the Delphi or the Bosch units are quality replacement parts?

1996 Dodge Grand Caravan, 3.3 L engine. When the outside temp is a good range (50 degrees F & above) there is no problem starting. But when it gets below 40 deg. F and really chilly outside temp, I still have strong battery power, but when I switch on the ignition, I don't hear the normal fuel pump activation swirl sound and does not crank - simply silent click. Then I can wait when the outside temp improves and cranks up no problem.

Black Beauty finally gave up. Replaced battery, replaced fuel pump relay. Would only run with starter fluid sprayed into the air intake. She'll crank but not start. Here she sits at the dealership.

I recently had my fuel pump replaced in my 2005 GTI ... twice. Both times, the fuel gauge no longer shows a full tank, and doesn't show empty tank correctly. Is there some way to reset the gauge? Is the pump somehow tied to the gauge, or did the mechanics mess the float up when they changed the pump? Sadly I had it repaired somewhere other then the dealer.

I just got delivered a 7.3L from down south. Batteries were dead so replaced both. Fuel was a couple notches above red line (much closer to red line than 1/4 tank) so I added about 7-8 gallons.
It will crank forever and ever...Won't start.
With starter fluid it starts but not strong enough to pump the pedal and rev it up to keep it idling.
I know s-fluid is bad but if I continuously spray with key turned forward it will run but as soon as I let go of key it shuts off.
20 degree weather and it was delivered to a parking lot so I cannot plug it in.
Was told to check filter cap, turn key, and see if it fills bowl with fuel....if not then it is fuel pump. Someone else mentioned that it could be bad crank position sensor? Does this sound like fuel pump?

I have a 2001 Ford F250 truck -- it was stalling out (which was diagnosed as a faulty fuel pump), so I had the dang thing replaced. But nearly 6 months later, it's randomly stalling out again when I put it in reverse or stop at a light.

1995 Ford Explorer, 4 ltr. engine, pushrod. Will not start. Replaced fuel pump, fuel filter, every relay, pressure regulator, and the crank position sensor. I realize there's a whole bunch more parts under the hood, but I am ready to give up. Before the fuel pump would not run. Reason for replacing the parts. Now it won't stop running and you can feel the fuel by-passing at the pressure regulator. When checking the pressure at the rail I get zero !! I used a tire pressure tester for this. And, like I said no pressure. This vehicle has around 170,000 miles on it.

So after a long trip from my vacation I ended up running over a dead deer on my 2004 VW Jetta GLI 1.8T AWP. As soon as I hit the car turned off. I was looking around to see what the damage was and everything looked intact but my car still wouldn't turn on. I checked some things and came to the conclusion that there was no fuel running to the engine (whenever the key would be on the "ON" position the fuel pump didn't make the usual "whirring" sound meaning it was on).
So I checked the fuel pump fuse, that was good but when I checked if there was current in the fuse, there wasn't. Then I disconnected the fuel pump to see if there was current going through the connector and there wasn't. This led me to check the fuel pump relay. Relay looked good and when I checked to see if there was current going through to the relay, there wasn't. So my issue is that the car is not turning on because there is no current going through to the fuel pump and no current to the relay and fuse.

During recent trip to WITW 2011, I started smelling fuel vapor after stopping and getting out of the car. The smell was easily noticeable near right rear wheel which is obviously at the fuel filler door and neck.
Also, at one time the fuel level showed tank 3/4 full, but after filling it up I discovered that it was nearly empty with appx. 3 Gallons left. After filling the car back up to full, the fuel level went back up showing full, however the fuel vapor odor stayed the same on the way back home.
I have scanned the car and no codes.
Inspected under the car for fuel leaks and found none.
Removed access cover over fuel pump under rt rear seat and did not see any signs of leaks.
Removed rt quarter liner to visually inspect, but did not see anything unusual.
Which component could cause vapors to escape if faulty? R32 now has 31k on it.
I searched and read about possibly faulty fuel sending unit causing faulty fuel level reading, so I will be checking that next. However, no mention about fuel vapor problems.

Long story short, my car died on me shortly after pulling out of the driveway a few weeks ago. Initially I thought it was my fuel pump because it wasn't priming when I had the key turned to the "ON" position. Here's what I know for sure:
The fuel pump works. It was tested and is not the issue. The relay is good.
The fuse from number 28 is good. There isn't any power at the fuse. The shop has been tracing wires and looking at diagrams and cannot find any breaks in any wires.
The ECU has been swapped for another one. When I turn the key to the "ON" position, the check engine light and EPC light come on, then turn off after about 3 seconds. They do not stay on.
What else could it be? Car in question is an 01 Jetta 1.8T AWD motor code.
