    Have not check the fuel pressure or engine codes.

    Check the fuel filter,pressure regulator, fuel sock(for clogging) Check the battery terminals,power to fuel pump,distributor power also plug spark, Does it pop or try to start at all? Does it turn over really fast? Check the lower intake gasket for a leak. You need to run a diagnostic reader on it. There are to many variables and not enough info. Just trying to help.

If it turns over when you turn the key and doesn't start, try taking the belt off and starting it, if it starts it probaly is your smog pump (froze up) check all pumps.

I would call that a good guess after five fuel pumps. Gosh, Jonah, paying for a little diagnostic testing would have saved you the cost of four fuel pumps.

Maybe your problem is with the one or many injectors, if just one is bad, you will have problems. Get yourself a multimeter and set it to read in ohms and find what spec the injectors should be at. If out of spec, then you need to replace that one injector(s).

My car won't start I have changed the coil fuel pump fuel pump relay and the Mfi relay I now think its the crank shaft relay but I do not know help me !


Sounds like maybe the main computer is bad. When you cranked the engine there is not any indication that it is firing. If you have changed the fuel pump and coil and it still wont even fire, the computer is most likely the cause. Even if the timming was off you would still get some indication that it was trying to start although it probably would not if the timming was off, but the fact it's not even trying to fire yeah that's my take.

94 jimmy will crank, runs good when cranked but when you turn it off won't crank til you let it sit or the next day. I can hear the fuel pump come on. The rotor button on the distributor is not po


Concentrate on the starting circuit: from the ignition switch to the neutral safety switch to the starter relay to the starter solenoid on the starter. If it won't crank, one of these parts or the wiring associated is not working right. Quite often the electrical contacts in the starter solenoid become pitted, slightly burned maybe, and lose contact. If you have power on the solenoid wire when key is held in crank and starter won't operate, the solenoid is the problem.

Car cranks but doesn't start changed fuel pump, changed fuel filter, no security system. fuel injectors and pump work and have new plugs


Hello
The engine and transmission in this cars drivetrain is fully electronically controlled by a computer called the PCM (Powertrain Control Module). Whenever a problem like this occurs the computer stores a record of the problem in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s)

First, charge your battery all the way, Is your check engine light on? How did you determine you have spark and fuel? Did you try starting fluid?

Dodge cummins won't start, fuel reaching injector pump but no fuel coming out of injector pump.


You said you have fuel flowing from the inlet line of the injection pump? But not at the injector lines?
