Car Wont Start

teedoff00 · 12-06-2007, 03:59 AM

Hey I have a fuel issue. I was driving to the store and when I stopped at a light the car died and wont start back up. It cranks over and all but my AFPR shows 0 PSI. So I figured my fuel pump went out, I replaced it with a Walbro, wasn't that. So I swapped the fuel relay sensor on the passengers side of the engine compartment, wasnt that either. I have been trying to find an answer in the TSRM but I havent been able to find anything. HELP PLEASE! What could it be...
Thanks

Did you troubleshoot using this as a guide?
MK3 TSRM On-Line
specifically the first on the page, it has some more things to check then just the fuel relay sensor.
Did you check the EFI fuse for instance?

yeah I already switched out the fuel relay sensor, I basically dont have any registering fuel pressure, so I figure something isnt turing on the (new) brand new fuel pump (thought to be the problem). But what could it be... CPS, ECU, Sensor of some sort... What should I check and how is the best way.
Thanks again for all the help.

have you checked the efi fuse? this will stop the injectors and fuel pump running
try jumping +B & Fp in the diagnostic box with ign on, do you hear fuel running?
