starting difficulties???

[sam385]

i have a 1994 7.3 IDI...we have rebuilt from bottom to top. it was running splendidly until last week. the glow plug system seems to be working properly and the fuel is good. in the morning the van starts (block heater or not) --runs for a couple of seconds, then, stops. if i grind on the starter for a few minutes, the van starts up and runs without a problem. if i stop at the job for a while...it will at times start and run and at others will require a starter-burning grind to get running again... guys...i need some input here....

ipr or icp sensor more than likely get it hooked up to a scanner and see if you have any codes sometimes i have seen them go bad and not send a code thou.

if you have an IDI then you dont have all those sensors. could be an air leak, check all return hoses and plastic caps, if they are oily you know they are leaking. if they are dry they still might be letting in air but not enough to let diesel out. check by starting truck let come to idle and spraying a little carbureator/throttle body cleaner directly on each hose where the clamp is and listen for idle change. if idle changes it's leaking. Might also be a slow metering valve on your IP. Try this, remove your fuel filter, fill with dextron II, start her, shut her off, and let sit a few hours then go on a drive and see if that dosent lube things up. It worked for my IP issues (for now anyways)!
DO NOT REMOVE the govenor top cover unless you know how to re-install the FSS solenoid and test if it is installed corectly. If not you will not be able to turn off the engine with out stopping the fuel, and could have a runnaway engine!
