88 problems
ok son just bought a 88 f150 with a 302, here is the problem...it has sat for several years and when we got it it would start and idle but nothing more, give it gas it would die, changed the fuel filter and then the reat intank pump went out, changed it, draing the sas and put in fresh, it started right up both at idle and when reving the motor, sut it off and it wouldnt start again, will run if you shoot either to it but nothin else.....it has plenty of fuel pressure now and i am thinking the injectors might be cloged up but not sure where to go look now.....any suggestions

If you did check it with a gauge and got 30+ PSI fuel pressure then get a noid light and plug it into one of the injector plugs. Crank the engine and see if it flashes.
If the noid light flashes then maybe the injectors are all plugged. Also check the vacuum line and wiring going to the MAP sensor.
Could also be a bad ECT sensor.
If the noid light did not flash then check for power going to the computer on pins 1, 37 & 57 with the key on and any pins pushed out of the computer plug. If you have power check the small black wire with a green stripe at the NEG post of the battery for a good ground. If that is OK then check for grounds at pin 40 & 60 of the computer plug. If the grounds are all good then change the computer.

I would find out if the injectors are firing or not before taking out the fuel rail.
You can rent a noid light at a auto parts store or see if you can hear them ticking as you crank the engine or put power across the injector pins with a 9 volt DC battery and you should hear it tick (do not use the 12 Volt from the trucks battery or you can burn out the coil of the injector).
