01 f350 7.3 dead please help

01 F350 started running rough and eventually would not pull itself. Now it will not crank at all. I have changed fuel filter and checked air filter still no go. Last summer I got some nasty fuel and had the same problem. Had to take off the tank and clean and finally with the help of some tranny fliud straight in the filter bowl got it running. One month ago it quit and I changed filter along with more tranny fluid and it was running fine. This time the tranny fluid and every other injector cleaner on the market will not help. could it be plugged injectors or injector wiring or possibly the cps. Any help would be appriciated. Thanks, Jimmy

Check the fuel pressure and oil condition. Is the tach working when you try to crank? Make sure the batteries are fully charged. Is the CEL on?

The check engine light is not on. The batteries are hot. I will have to check the tach. Thanks

I would have an injector contribution test and injector buzz test done. Also check the fuel pressure. I would also check the uvc ( under valve cover wiring harness) make sure it is not burned or melted. They had a problem with the connectors melting along with the wires melting and making a bad connection. But an injector contribution and buzz test should show you that.

I don't think you have a cps problem. I think it is more of an injector problem.

Hauled truck to Ford dealership and had it checked. They are telling me that the pump is bad. But he could not tell me if it was the one on the frame rail or on the motor. They told me it would be around 938.00 parts and labor also included in that was cleaning of the turbo and some turbo boots. They said it had some soot build up in it. I'm not to familiar with that so hopefully you guys can give me some insight. Also if it is the injection pump is their any upgrades that I could do such as different style of pump etc. Thanks, Jimmy

I would ask them to define which pump is bad. That way you know. By law they have to give you that information. They should have the capabilities to tell you as well.

As for cleaning the Turbo I know on a 6.0 that seems to be something that needs to be done. But on a 7.3L I am unsure if they are not trying to do it so they can jack the price up some.

As for an Aftermarket pump check with some vendors on here and see. I would ask DPP.

Vital I think you meant Injection Pump. HPOP is High Pressure Oil Pump. This is the fuel pump.

Actually BC the superduty's dont have an injector pump per saythe hpop is what fires the injectors but still if they are charging that much for a fuel pump thats rediculious
