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!!
