so i have had this problem for awhile now and my mechanic has fixed a few sensors and wires and complete tune up and now it starts adn runs fine until it warms up (maybe 20 mins idle) and stalls, and will crank but not start. they have traced it to no injector pulse, lots of fuel pressure but no pulse. any ideas, anyone

 

Interesting problem. The injectors are batch fired, each bank pulsed separate from the ECM so I'd rule out that. Two separate power feed circuits. Something is telling the ECM not to pulse the injectors. I wonder if the ignition module is heating up and not sending an RPM signal to the ECM?

 

I would check to see if you have spark at the same time you loose the inj pulse.

 

yes there is spark

spark control modual was changed the last time it died on me thinking that was the problem but still happening also done at the same time was
plugs
wires
cap rotor
oil change
mass air flow cleaned up
temp sensor
and i changed out the ecm with a new remanufactured unit before it went to the shop
