Cranks won't Start, Fuel??? Pump Replaced
Cranks won't Start, Fuel??? Pump Replaced
My car just died immediately after it started. I cranked it over and nothing, pulled the fuel line off the regulator and no fuel. I can't remember if the fuel goes to the regulator first or after anyway. I was going to change the pump. I can't hear the pump with the ignition on either. Comments?? Thanks

Re: Cranks won't Start, Fuel???
You can jumper the fuel pump in the diagnostic box to determine if it's fried. If the pump comes on with key on when jumpered but not when it isn't jumpered it is likely the fuel pump relay down by the ECU. If it doens't come on at all it's probably toast.

Re: Cranks won't Start, Fuel???
Hey great idea. I'm really busy so in all honesty I was looking for a few quick comments so I can get this car back on the road. I'll jump it and see. Your now officially back in my good books.. Just kidding.
Ya I'll just swap out the relay.

Re: Cranks won't Start, Fuel???
Is it cranking faster than normal? How's your timing belt? You won't hear the fuel pump unless the key is in the crank position.

And fuel goes to the regulator after the injectors. On a B6 anyways...

Re: Cranks won't Start, Fuel???
Oh man he's unrelenting. Anyway I slaved another fuel pump in and it's working but I didn't remove the cover plate from the pump on my car yet to make sure. Like I said I'm running all over the place today and didn't need this. I plan to finish this in the am. I was kinda lucky that it happened in my buddies drive way. If I bought an after market pump where is a good place to buy and what is popular. I'm familiar with the Walbro name. I just want something that's not a big issue to install.

Re: Cranks won't Start, Fuel???

Re: Cranks won't Start, Fuel???
Umm, that's my line. I believe that's an OBD2 thang.RS_OBD'oh_2 wrote:did you try the ecu reset? pull neg and hold the brake?
I'll unscrew the plate and double check the pump in the AM. Hard to hear with the plate in place. I think the tank and fuel pump are the only original parts left on my car. lol

Re: Cranks won't Start, Fuel???
With the key on and the engine off you can hear the fuel pump quite clearly. At least I could in my case. I would just get the best one I could afford. Rockauto...ebay...they all have the same stuff. your local partsource is easiest but will be the most expensive.

Re: Cranks won't Start, Fuel???
Ok, even when I slaved the other pump in it wouldn't work until I cranked the engine. I always thought the crank sensor had to see rotation before it would allow ignition and fuel? Anyway. I was a little surprised that the pump just stopped working. No warning no nothing. The spare pump is in and other than the fact I only have 2 screws holding the pump in vers 6 the car runs fine. I drilled out the seized screws before removing the pump but I think I'll just install a whole new tank. The pump and the tank are original to the car. I could tap out the old screw, I just don't like working on open fuel tanks. Boom! Thanks for the help, suggestions and English grammar lesson.

Wyt, you are mistaken. The ECM must see the CPS (NE1) signal before the pump primes.wytbishop wrote:With the key on and the engine off you can hear the fuel pump quite clearly. At least I could in my case.
It can be seen here:
http://www.mx-3.com/manuals/showimg.php ... F2-117.gif" onclick="window.open(this.href);return false;
simple test:Listen for operational sound of the circuit opening relay while starter operating
Plug in a spare distributor (or pop yours out if you're doing it anyway), turn the key to on, and turn the rotor by hand. you will definitely hear the pump come on then, as well as the injectors fire.
Now with Moderator power!

As I said in my previous post...jumper the pump in the diagnostic box, turn the key on, you will clearly hear the pump operate until the fuel rail is pressured up. The jumper bypasses the relay.wytbishop wrote:You can jumper the fuel pump in the diagnostic box to determine if it's fried.

Jumping the box is better for sure in that you don't have to try and hear the pump over the engine cranking.
