E150 5.0 problem
Ok my friend owns a 1991 E150 5.0L. Basically what it is doing is, when you try to start it, it cranks but wont turn over unless you pump the gas pedal. Then once you get it to start you have to continue to pump the pedal to keep it running.
Ill just list everything I did and checked:
Fuel pressure test: 40psi
Pulled the injectors and had them tested
Checked plugs, wires, distributor cap/rotor, ignition coil
Cleaned a bit of carbon build up off the throttle body.
Theres no CEL on and I have no idea what else to look at...
