thinkin crank sensor may be shot. i would check for codes, even if engine light isn't on. alot of times codes are stored with no light.

Holy Chit! did something in the body of the spider fail the injecters are hot all the time and the ECM pulses the grounds to fire them,when my crank sensor failed i had no spark and pretty sure i had no signal to the injector because my plugs were dry

TPS or MAP dieing?
