1987 F 250 fuel pump circuit problem

1987 Ford F 250 custom 4x4, started running rough, parked, went out a week later and can not start. I ran the diagnostic trouble shooting and it said the problem was with the fuel pump circuit. went to check the relays and cannot find them under the hood. The truck is new to me and i'm just getting familiar with it. where can i find the relays or a diagram of the wiring for the fuel system?

    on a 2002 chevy 2500HD, the truck was parked on a hill. the truck shut off. thought it was low on gas. put 10 gal in and it wouldn't start I have power at the plug at the pump. the grey wire fuel gauge works also, so I thought the pump burned up do to lack of fuel so I put a new pump in and it has power at the plug at the pump and it still won't start. I also swapped the relays at the fuse box under the hood removed the relay nad used a paper clip to jump the circuit and the pump doesn't work I hope you can me

1991 ford tempo ran fine went to store it started fine and then just died


Likely a gas or spark problem. Spray starting fluid into the air intake while cranking it. If it then runs for a few seconds, it's a fuel problem-maybe the fuel pump, filter, or injector circuit. Check if gas is getting up to the engine.
Buy an inexpensive "spark tester" at a parts store, and check for spark- if no spark, the ignition circuit will need diagnosed- could be the ignition coil, maybe the electronic ignition module-several possibi9lities. Let me know what you find, or if other questions..

Ford had a lot of problems with this engine. Most diagnosis requires a factory software scanner or one that can interface with the FICM module (fuel injector control module) Now you can perform injector buzz test and glow plug tests. If you can get running then also do a power balance test these test check fuel injectors statically and dynamically with the common rail oil pressure control sensor. These FICM modules are famous failure parts. Napa auto can get them.

Ford 1981 f 150 not running changed Coil distributor cap Roar arm plug wires did not help started bur ran extremely rough then died


motors need 3 things to run properly. gas spark and compression. the starting point. also spark timing.
the motor you are dealing with is easy. i just rebult a 1978. anyways sounds like a timing problem . first i would check the distributer. if all is ok spay a squirt of starting fluid in the air filter, or even wd40.,,,,,,,see if it is gasoline problem. isolate where the problem is.

Rough idle and lack of power


Since you have fuel injection for fuel delivery, something has to tell the system how long to have the fuel injectors open, and something has to tell the system when to activate each fuel injector ... unless you have throttle body injection. Do you know which type of fuel injection you have? I will need that answer above before telling you anything useful.

if the pump has been changed twice its probally not the pump. could be the fuel pressure regulator. the computer will still throw a fuel code but in order to really diagnose the problem they would have to test the fuel pressure.
