Pull your dip stick, see if the fluid seams runny unlike desiel oil, if it smells like fuel chance are you have the leaking injector bull shit that has plauged the duramax. Or track the fuel pressure.

done the sniff test,seems OK
will not start without help via starting aids(wd40,fluid,gas vapor etc)
it will run for a while then die.
New fuel filter. Ive hooked my snapon scanner up and watched it go all over the place with fuel pressures.
I guess I need a tech2 to really see whats up.What I really need is a local expert....

I know we're not in Orlando-we have the GM Tech II and the tools to diagnose the problem. Just throwing it out there just in case.

why not take it to a gm dealer? unless your out of warranty but it was my understanding that the duramax's have a 100k warranty or so? idk..

injectors have a 200K 8 yr warranty(if they feel like honoring)
this is out of warranty.
As for taking to dealer it would have to be towed to stealership(big bucks) and they quoted $4400 to do an injector job.Sorry but thats a little steep.
I ll do the work myself if someone will diagnose and point me in right direction.
Plan B is that I have a low miles 05 duramax motor and will swap if I can figure out how to reprogram the 01 ECM to 05 specs.
