2003 Duramax will not start engine is hot without prime.
Having trouble restarting my 2003 Duramax when it has warmed up for 10 minutes or more.
Starts cold with in seconds
No loss of power
No fuel in crankcase oil
Replaced fuel filter with in 100 miles
Replaced fuel filter/primer pump with in 100 miles
Will start when engine is hot after depressing primer pump 4 or 5 times (until firm)
i had a ford idi 7.3 that when it was cold would fire right up then when it got hot it would not start unless i used some kind of starting agent
when your wife ran it out of fuel your injector pump was ran dry no lube means alot of wear real quick and i think that is your issue
