Engine Performance problem
1996 Ford F150 6 cyl Two Wheel Drive Manual 75000 miles
My F150 4.9l Dual Tanks starts perfectly then stalls right away. Replaced IAC and fuel filter. I Can hear each pump working when key is turned on. Fuel pressure is normal. Has spark. Cleaned throttle body. I can get it to run by disconnecting the IAC then starts and runs, but if I so much as touch the eccelerator it stalls. Hooked up my Genisys scan tool an pulled a code that the scan tool didn't list. I think it was something like fuel pump voltage high. I am not sure if code was set by me disconnecting things during diagnosis. Any help would be very much appreciated.
