3406E won't fire up.

If you have any holes in the fuel line, loose fuel filters/fittings, or cracked pickup tube in the tank you could be sucking in air.

 

Post one says u got flash code 55 if no power to ECM no flash codes will show at al ?????????

 

There is no way the 5 amp fuses are for the amp meter. They would blow the second the alternator started charging.

 

I guess the ammeter could have a relay but why two fuses. Somebody will set us straight. The ammeter won't be switched. Turn on the lights with the key off and the ammeter should show a draw. The needle will move to the left of zero.

 

All the ecm does is activate the silonoid on the injectors, it doesn't control the fuel pressure. That is on the mechanical side of injectors. No or low fuel pressure will not fill the injector fuel body = not enough fuel to Pop off the injector.all the injector silonoid does is modulate the fuel flow if there isn't enough fuel pressure then it is starving the injectors.

 

OK, you have some diagnostics to do here, but nothing too hard. First you need to turn the key on and make sure you have power to the shutoff solenoid. Once that is done, go to the primary filter, and disconnect the line from the inlet to the fuel filter, crank engine and see if you get good fuel flow. Next hook the inlet line back up and remove the outlet line and keep chasing.

I have ran into this before. If you disconnect the fuel line at the filter you know that you either have a bad shut off solenoid or transfer pump, If you have fuel getting to the filter base, but not coming out you have a bad filter base. Yes I have had a few filter bases go bad. This is a really fast and quick and dirty way to find most problems in about 15 minutes. If you are not getting fuel to the transfer pump, than debris in pick up tube. You get the idea.
Good luck.
