Golf IV / Jetta IV :: 2005 1.8t AWP Cranks But No Start - Cannot Hear Fuel Pump Priming
May 5, 2016
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.

Ok, car won't start. fuel pump not priming. tested the fuse, no power coming to it, fuse is good. even used another fuse. my flex connection on my dp blew out, rusty had a leak there for a while. in any case patched it up McGyver style till a new dp arrives. I backed the car off the ramps and shut it off to clean up. when I went to test drive it fuel pump wasn't priming.

Sometimes my Bravada won't start. It cranks good (new battery) and I can hear the fuel pump , but it doesn't fire up. I just got it back from the repair shop.?

No more fuel pump priming sound upon opening door but the car still fires up without any problem. And yes it was after the car sat for a day or two without being started. I kind of got used to that sound and was like now that it is gone. Should I be worried my fuel pump is on the way out?

Lately my car takes 2-3 cranks before it starts and I'm thinking it could be my fuel pump. There were a few times recently it took like 8 cranks to start. How to test fuel flow to see if it has issue? Also, could a old battery cause this issue?

Geo won't start. It has a new battery and air filter. Just replaced the fuel pump and fuel filter. I don't hear the fuel pump "whirring" when I put the key in the ignition (to on position). All the dashboard lights come on when the car is in on position.
I suspect the relay or the fuse, but having trouble finding the correct one of each. What does the relay look like? i.e. part number? What is the spec for the fuse? 20amp 30 amp? This has been a great car.

The car cranks absolutely 100%, in no way is this the battery, it just will not start. Then I noticed the fuel pump wasn't shutting off, I only had a quarter tank in the car, I figured as hot as it was today I was getting some vapor lock with the fuel. Went and got some gas, still wouldn't start, then the dash started yelling at me telling me I have no oil pressure, shut off the car.........car you are not running calm down. So then there's that along with the car not starting. I took the fuel hose off to make sure I was getting fuel, I was, so I took the key back out, but the car would not give up, the fuel pump kept going and the dash was blinking violently. When I put the hose back on and got compression it finally stopped, that can't be how the cars work can it? The fuel pump doesn't shut off if there's no compression? Checked all fuses and the fuel pump relay, every was fine, the fuel pump even still ran with the relay out. What could be going on, I can't seem to find one damn thing even related to the fuel pump not shutting off.

Was driving normal and my 2004 r32 died. It felt just like it ran out of gas. Fuel pump was not making any noise. I replaced fuel pump relay and now i can here the fuel pump making noise. Pulled the fuel pump line off and fuel is coming out the line. So now i checked for spark and have none. I have 12 volts at the coils. I ohmed out the crank sensor and have .777 k ohms. I also checked codes with generic snap-on scanner and found no codes.

Got done with replacing head gaskets and intake gaskets, Van started fine and I backed it out of the garage. Left it running and put down ramps and drove up on them so I could get under and connect the exhaust. Got that done and then got back in it and all it will do is crank and it will not start now. It also has a new cam shaft sensor( wire broke on old one). I can hear the fuel pump when I turn the key. It is like now there is no fire to start it. What could be wrong? What do I check? What causes it to fire? If something was connected wrong, would it have still started and then wont do anything but crank? Got dark on me and started raining so I say tomorrow is another day. I feel it is something simple.

when I turn key I should hear fuel pump, I don't. I can jump pump & it will run but it still won't start. I reset inertia switch, switched pumps (new one) still won't start. What next????

I notice that not only does the fuel pump primes when the drivers door is opened but also when the rear hatch opens.

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?

01 7.3. Cranks, won't start. Tank was at 1/4 but is full now. The lift pump runs, I can feel and hear that the motor is spinning when I cycle the key. I removed the fuel filter and cycled the key and get no fuel into the bowl. It looks like the lines are stainless from the pump to the tank so I doubt it is sucking air. I pressurized the tank with a shop vac and I get fuel coming into the filter housing. Am I missing something obvious? I have never seen an electric pump that would run and not pump fuel. I removed the suction line at the pump and don't feel any suction there.

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.

Accent that will crank but won't start. I found out that the fuel pump was not spinning, so I purchased a replacement. Before installing it, I connected all of the wires and the new pump wouldn't spin either. I then hooked the pump directly to the battery and it spins with no problems. After that I realized that the power wire for the pump must be shorting somewhere. So I hooked up the old pump and ran a new power wire from the relay box to the pump. The pump now runs, but the car still won't start. I definitely have fuel to the rail now. I unhooked the fuel line at the fuel rail and it sprays as soon as I turn the key to "On". Now all I need to know is if I'm forgetting something (bleeding the fuel rail?, etc.). Are there any other parts I'm forgetting?

I've followed steps 2-6 from this image
I don't feel any pressure in the hose from the fuel filter. I can hear a buzz (guessing its from the fuel pump) but no pressure.
I've checked both fuses, the efi main relay, and swapped out the circuit opening relay with a known good one and all checked out good. Only thing left is the fuel pump or the writing and electrical connectors.
Car has pretty much took a dump one morning and has almost no power. I can't find anything else wrong with this car besides this. Is the fuel pump the problem even though I can hear the pump?

I'm working on one of our fleet vehicles here, a 1995 Explorer. about 2 months back, it stalled out. Got it back to the shop and turned the key on .... I couldn't hear the fuel pump. I replaced the fuel pump and the fuel pump relay. Vehicle started right up and seemed to run O.K. About 2 weeks ago, it stalled out again, same symptoms, acts like it runs out of gas and can't hear fuel pump.So, I have been playing with it and find that it starts up great in the cool mornings. In the afternoon when the temps are hotter, it won't start (can't hear fuel pump). The following morning when temps are cool, it will start right up and can hear the fuel pump. I almost wrote this one off as a defective fuel pump, but I'm not sure on this one.

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.

I have a 2005 Golf GL trim 2L SOVC. For months now the car won't start on the first try. One must let off the key and disengage the starter then reengage. It always starts the second try and never starts the first. Once the engine runs for a few seconds, if you turn it off, then start it again, it immediately starts. It's never a problem en route. Only if you let the car sit for a while, say 8hrs or more, (when the fuel pressure dies) do I observe this "no start on first try" behavior.
I recently replaced the plugs and fuel filter and cleaned the throttle body. It's a little better now. It stumbles like it is going to start on the first try after sitting but doesn't.
I exposed the fuel pump and measured the voltage going to it. When you turn the key to "on" position, the engine computer put's voltage to the pump for about 1.5 seconds and that's it. So while you are cranking I guess it expects that 1.5 seconds of pump operation is enough. I put my fuel pressure guage on the port near the injectors, and, as I suspected, the pressure only builds to about 28lbs. On the second try it gets up to 40. Once running it's about at 45lbs.
Sounds like a firmware bug to me.I'm considering wiring in a switch that I can toggle to deliver more on time to the pump inititally - maybe 3 seconds? Is this normal?
I noticed that when I put the fuel pressure gauge on initially there was zero pressure. Is this normal?
Shouldn't a check valve keep it at pressure? Where is the check valve located? I'm also getting a P0171 code "engine too lean". I repaired a hole in the air hose going from the air pump to the throttle body - still get the code. All hoses look good.
