Do you have a scanner, not code reader but a scanner? Many possible reasons for this, ignition module, even though it will run when force feed, shorted/out of range tps, defective cts, crank sensor, fuel pump, need a scanner to view live data. Try unhooking some sensors then try it.

there was a scaner hooked up it is a snap on solus scanner there were no codes or anything abnormal present however i did also think it was the ignition mod there was another thing i did i unhooked the idle air control and it would back fire through throttle body. im not sure if this gives you anymore ideas on the problem. is there a way to test the ignition mod? and what it cts stand for? thank you for your time and efforts.
