Engine Performance problem
2004 Ford F250 V8 Four Wheel Drive Automatic 74144 miles

Hard start problem had been occurring, changed oil, and fuel filters, still no help. Finally a no start condition occurred. Towed in shop they diagnosed the problem as a code they retrieved as: Fuel Injector control module, injector control pressure switch, and a 3 way connector. Once completed we still had problems with a hard start. Checked the batteries and found one battery completly dead and the other at 1/2 life.

Question: Can a battery issue cause these codes and tech. To do what he did when it is only a battery issue? Can he have mis-diag. Problem were we did not need these parts?

Thanks for your help.

Do you
have the same problem?

If its cranking over and will not start you can try doing below to determine if its a fuel or spark problem.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, If you can hear the fuel pump come On- check the fuel pressure with a fuel pressure tester designed for your fuel system to rule out the fuel filter/fuel pick-up strainer/fuel pump/pressure regulator and also listen to the injector/s are they pulsing or hook up a noid light and see if it flashing, If you don't hear the fuel pump, check the fuel pump fuse and fuel pump relay-Depends on what type ignition system is yours, No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, camshaft and crankshaft position sensors and computer Note: If it doesn't apply to your vehicle disregard it meaning if it doesn't come with one ignore it and continue testing
