What fuse is it that likes to blow? The one that blows when to heater in the fuel filter housing shorts out. Do you get a wait to start light?

not sure what fuse that is. ill check. i do get the wait to start light. i drained the filter housing and ;cycled the key a few times but no fuel is pumping into the the housing. i filled it with diesel and still wont do anyting. there is a buzzing from something on the firewall passenger side. what is that?

I think John was talking about the fuse that goes to the fuel bowl heater,cigar lighter and pcm.If the fuel bowl heater shorts out if will blow the fuse.No power to the pcm.

If that pump has blown two fuses it must be a wire grouding out or the pump has gone south?

Barry is right. The one to the PCM was it. I couldn't remember which one it went to. Either the PCM or IDM. I didn't remember. But!!! It got you looking for fuses, and you found the problem. Or at least you know where to look from here. Either a short in a wire, or a bad fuel pump.

ironic that you and I are running into the same issue after an injector install, however I do not have a blown fuse. Might want to check into whether or not your injectors are even firing. I know mine are not. If you have an AE run a buzz test. Mine failed the Buzz test so I know there is a communication issue between the IDM and the PCM because if threw a code after the buzz test

Jerry said his truck fired right away, then died and hasn't been able to restart. His problem is no fuel since the pump wouldn't fill the filer housing. He's got either a short in a wire, or the pump is bad.

Now if the fuel gets fixed and the truck still doesn't fire up, then a buzz test would be a good step.

Ok my truck is running. Woohoo. The pump was bad. Four new injector, four new glowplugs, new valve cover gasket, new filter and new fuel pump. It was worth all of it just to hear it run again. Thank you for everyones help. Couldn't have done it without you guys.
