the mechanic who has it thought it might be the AMM but when that goes, doesn't that usually throw a code and trip teh check engine light? i do have a spare junk yard one that i think works fine in my trunk.

i have also thought about the reference sensor but willt hat cause this or more of a no start?

i had the shop check the fuel pressure and the ground, i will pick it up tomorrow and deal furtehr with it myself.

i still think its the ecu as this is exactly what happened last time but who knows.

thank you for the ideas.
