Golf IV / Jetta IV :: Car Won't Crank / Start - Faulty Fuel Pump
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.
Ford Super Duty (1999-2016) :: Fuel Pump Come On But Starter Won't Crank When Turn The Key
I have a 1999 f350 7.3. Turn the key lights and fuel pump come on but the starter wont crank. I replaced the starter and checked all the fuses i could find. The only way I can get the truck to crank is by jumping the relay under the hood.

I am having a slight issue with my cluster. When I turn the key on or start the car, the speedo needle goes crazy for about a minute then stops above 0mph (points at 5mph when im not moving). While that's happening, the other needles don't work until the speedo normalizes. It also does this when i turn the car off. What this could be? I heard about the VSS can cause speedo issues but what about the rest? I also heard the mk4's can have cluster failures. it's a 99' mk4 vr6 jetta 5spd.

View 3 RepliesGolf IV / Jetta IV :: Fuel Gauge Not Correct After Fuel Pump Replacement
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.
View 1 RepliesGolf IV / Jetta IV :: R32 Cluster Swap - Reads Wrong Fuel Level
The cluster works fine in the car. MFA works. The immobiler does activate but my ecu has an immobilizer defeat so it doesn't kill the car. I'm not having any of the usual issues with cluster swaps. I'll get the immobilizer issue recoded later. My issue is with the fuel level indicator. I have half a tank of fuel and it is reading full. I've researched and found out the r32 has 2 fuel sending units and this may be where the problem is. If so is it a matter of re-adapting the cluster or is it slightly more complicated than that?
View 3 RepliesGolf IV / Jetta IV :: 2002 - Cluster Lights Turn On After Locking?
I just bought a 2002 Jetta 1.8t today and have a few questions for some of you with vast knowledge on these cars.
1) When I lock the car the interior lights don't turn off, and about 5 seconds later the dash lights turn on. I sat outside in a lawn chair and waited 10 minutes to see if they would go off and they didn't. Would that be a faulty door switch or the CCM acting up?
2) Doing a 3" catless downpipe with 3" straight pipe?
3) Are there any major issues I should look out for? The car seems to be in pretty good mechanical condition, minus a loose exhaust hanger that rattles at idle. Not bad for 119,00 miles.
Golf IV / Jetta IV :: 12v VR6 No Longer Starting / Crank Super Slow Once Or Twice Then Stop
My jetta failed to start for me at a local grocery store. It would crank super slow once or twice then stop. Tried push starting it to no avail. Got it towed home, and thought to try a new battery, figuring that the alternator might be bad. Got a new battery yesterday (still under warranty), threw it in the car, and gave it a shot. It turned over slow 4-5 times then stopped.
I have been having the ever-annoying shifter rod rattle for a while, and it recently got much more obnoxious. I am beginning to think that maybe the more obnoxiousness was my timing chain though. It sounded like marbles, but the noise sounded like it was coming from the intake, not the side of the motor. Also, not sure if this matters but the battery terminals got super hot after I tried to start it last. What to check? Electrical short? Timing off? Something from the shifter rod fell into the motor? Some other strange issue?
Golf IV / Jetta IV :: Pump Won't Prime After Cleaning MAF Sensor / Car Cranks But Not Starting
I'm having a situation here. Yesterday I decided to clean the MAF in my 01 VW Jetta 2.0, so without disconnecting the battery I unplugged and took the MAF sensor out and sprayed it using "CRC MAF sensor cleaner", let it dry for about 30 to 40 minutes and then re installed it. When I tried to start the car, I opened the ignition (ON position) and didn't hear the pump priming, still tried to start the car, it when on for about 2 seconds at rough-800rpm idle then rpms dropped and car stopped running. Then, I tried to started it again a couple of times more and I still don't hear the fuel pump priming and the car will crank but not start.
Did I ruin/blew the fuel pump or something in the system? I don't understand what could have possibly gone wrong. I already tried searching for it but did't find the exact same situation and though details might be important.

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.
Golf IV / Jetta IV :: 2001 1.8T AWD - No Power At Fuel Pump Fuse
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.

I have a 2005 Volkswagen GTI with 80k miles. Just yesterday I went to school and the car drove fine. But when I came back and tried to start my car, it stalled out after a few seconds. Now I thought this was a bad fuel pump until I checked it and found that the fuel pump wasn't receiving any power. I checked the fuse and it was intact. So then I went to check the relay and found that if I unplug the relay and plug it back in, the fuel pump momentarily receives power for about 2 seconds then nothing. Any clue what the interference could be?

Golf IV / Jetta IV :: 2004 - Die Randomly While Driving - Fuel Pump?
04 jetta 1.8t
apr tune 1.6v
neuspeed 4bar fuel pressure regulator
3" turbo back
APR TIP
This is the second time this happened to me. First time was about two weeks ago where i was just driving and the car stalled. Tried to start but it sounded like it just wasn't getting fuel. Brand new battery, terminals are clean) Got it started and it was revving high like a cold start, normal but why after driving for 30 mins? EPC light came on also which was strange along with the CEL, a buddy checked the code and it was for the secondary air injection pump. (I have not had that go off in a while. Code po4011 secondary air injection. Had this issue a while ago with that code when i did a short ram intake. Tuner cleared it so i can pass emissions. ) Now today it died about 2 miles from my house. Same thing but no CEL. EPC light came on and car was revving high, luckily 3 cars behind my buddy was there and he give me a push into the gas station. Once again it wanted to start but i felt like no fuel. waited a few minutes and it started right up again until it almost died in my drive way. Cluster comes on when it dies. ignition is good.
My big question is the stalling part and the EPC light coming on, then the car revving like it is a cold start but not stopping? and i need this car to be working.

View 1 RepliesGolf IV / Jetta IV :: Filler Neck Seems To Back Up With Fuel / Shuts Off The Pump
Ever since i have had my car i have had a slight problem re-fueling. The pressure inside the tank doesn't seem to vent correctly and the filler neck seems to back up with fuel and shuts off the pump (too much back pressure) when i'm only ~30% full. I can elevate the problem by re-fuelling slow enough so that the pressure can vent back through the filler neck but it gets rather annoying to sit at the pump for 10 minutes re-fueling.
