gchemist: well the ether isnt working so I might as well stop using it.

Yep, I have put fuel down the TB and it wont start on that either.

The low compression does concern me in the long term somewhat however its not the reason it wont start, if those 2 cylinders were totally dead it should still fire on the other 4 each time the engine rolls over but it doesnt.

The truck will start up for a second or 2 when its left alone for 24hrs or so, but subsequent attempts to start immeaditaly after fails. That fact makes me think that the poppets are clogged or the injector coil is fried and just over time fuel will dribble into the cylinders allowing it to momentarly fire up for a second or so if left alone long enough.

gonna pull the upper intake today to check the poppets for fuel flow. pressurize the system, hook up the injector harness, disconnect the coil harness and have someone crank the engine over.....if I have fuel spray then I have another issue, if there is no fuel spray that should verify if there is a spider issue.
