1996 7.3 just cut out while driving HELP

214000 miles. its like the motor was just switched off. 1 minute were doing 70mph and the next we are coasting to the shoulder. i turn the key and all the lights and buzzers work, glowplugs and stuff. motor cranks but doesnt fire. 1st deisel... all the fuses under the dash are good. i dont know where to start.

new fuel filter 186 miles ago. when i change it my friend said loosen the cap and turn the key and the filter will fill up. i tried and it didnt fill up. i filled it from a jug and the van fired right up. ran fine for 186 miles.

oil is full and clean. no tach...

i was just driving along and the motor shut down like i turned off the key.

any help is appreciated. anything. i am poor and desperate

the only thing i disconected to change the fuel filter is the "doghouse" and a heat shield. i have been reading that there is a heating wire that gets ****ed sometimes while changing the fuel filter but i drove almost 200 miles after that. the fuel computer is on that same circuit.

i have been told by 2 different mechanics on the Roush Racing team (seperatly) "starved for fuel"... they have 12 vehicles with this motor in their fleet that they maintain. i am being told to crack the fuel line at the head and crank the motor. i will know if there is a fuel problem right away.



since i know nothing about this motor i will have to figure out how to get that acomplished in a van.. they're shop is in NC so im on my own.



what i do need to know is where i can find all the fuses on the E series. i checked all the fuses under the dash but i am sure there are more i cant find... who knows where they are?

Any number of things could cause that problem. Short to ground on any input sensors. Typically the ebp sensor is the culprit. It usually burns internally and shorts out causing pcm to shutdown. Cam sensor will do the same. Typically if pcm related by short, when key on engine off either no check engine light or it will flicker rapidly.

If the tach is not moving when you crank it, my money's on the CPS.

Welcome to guzzle's CPS R&R Web Page<

I would double-check fuses, too.

there is a schrader valve on the driver side of the fuel filter. when i crack that and crank the motor fuel shoots out.... the scanner reads 160rpm or so when cranking so im thinking it isnt the cam senser...

Is this a fuel injecter line?



there is one on each side of the rear of the motor... the shoot fuel when i crack them and crack the motor.

i changed the cam sensor but i didnt think that was it anyway. was reading rpm's on the scanner

Runs on starting fluid.... High pressure oil pump has oil in it



If the fuel is going into the back of the motor, both sides, inside the valve covers does that meen the high pressure oil pump is doing its job?

stopped by the dealer, but it was after 4:30 and there werent any mechanics around. the service manager told me that the mechanics wont talk to me. it is $196 to start diagnosing... and that doesn't guarantee anything. could easily get over $500 before i even know what needs to be repaired. he is pretty vague about anything i ask him.
