    [quote=”hllywd964″ post=34728]2003 Hyundai Santa Fe 3.5 liter AWD..I’ll try and be succinct. Had an issue with my power steering pump needing replacement. To gain access to top mounting nut, I removed the top plenum, and after repair reconnected everything. Car will not start since this repair. I initially thought it was the fuel pump, cause after I turned the ignition to the on position, I didn’t hear the 2-3 sec whine from the pump; and after checking that the truck had spark and voltage to the coils I figured I was right. I accessed the pump, double checked to see if there was voltage at the pump connector (there was) and assumed it was the issue. Replaced the pump with Hyundai OEM pump…not the issue. What happens is the truck starts and stalls immediately..if I hold the gas pedal down alittle it will run, rough and backfiring, but will run. I also checked the fuse relay with a test light, and replaced it with a known good relay, and no change. It seems to me to be a fuel delivery issue, but I’m stumped. I have spark, so not the crank sensor..I checked the volts and continuity of the crank sensor and cam sensor, and all is good. The fuel pressure regulator is new, I replaced it with the pump, just because. I don’t want to throw more parts at this, thats why I’m asking for assistance. The battery is charged, and I checked every fuse….no issues there…I also checked the inertia switch, and that is not the problem. Does anyone have any ideas?? Please help!!

    Are you 100% sure you got the wires set right?????
    Iv got a 93 ford f150. Between 90 and 94 there wear 3 different styles of wring….
    Whats even more weird is in 93 trucks made before 06-22-92 and trucks made after that had 2 different styles

    I really doubt you have jumped time…

    Could the car be throwing its self into limp mode????
    Are you back firing threw the tail pipe???
    Are you back firing backwards threw the plenum?
    Are you sure its a BACK FIRE???
    If the plenum did not seat properly you basically have a internal vacuum leak and that could cause some issues.
    You did not over tight the plenum and crack it did you???
    Are you smoking black or any other color out of the tail pipe???
    Double check all plugs and hoses one more time…

    In my mind you have – The firing order wrong the engine or you have something unplugged or plugged wrong.

    I hope Iv helped.Thanks.

    Ps. You might try resetting the ECM/PCM/Computer.
    Disconnect the battery for 15 mins and Reconnect and try again.
