Thread: another problem... wtf

so i had to change out my fuel pump to pass smog. i bought one off savo and i know it works. after i made the switch, the car won't start ever. i've been cranking it sparatically through the past hour. i've double-checked everything i can think of (everything is plugged in and all the lines are hooked up and i can hear the pump turn on). i didnt touch anything else at all, wtf is goin on?

If u really want to check if it working take off the fuel line off the fuel rail to see if fuels going through. Check for spark? I had something similar to this. I found out it was my ecu chip was F'd up.

yea, i know for sure that there's fuel being pumped out of that fuel line. its so crazy cause i havent touched anything else. the car was working fine before i switched out the fuel pump.

Heres the steps I would take to figure out what happened. Since the last thing you did was simply change out the pump:

1) Disconnect the inlet of the fuel rail (2 10mm bolts) and point the end toward an empty cup. Have someone try and turn the motor over, and you should see fuel spit into the cup. You can rule out the fuel at that point.

2) If nothing spits out, then double check your work at the pump. If worse comes to worse, you can simply swap pumps back out to verify the pump you purchased from Savo is in working order.

after checking for fuel at the rail (which there was fuel but not a lot), i took the pump out again (for the 4th time) and discovered something.... you know there's supposed to be a rubber o-ring on the fuel outlet of the pump... who knew? i hate myself.


problem fixed. thanks to everyone who replied :D

yea, the last time i looked at the fuel pump at all was like three years ago, so naturally i guess, i didn't remember that o-ring. after all that frustration, im gonna remember that bch forever...
