Cranks good but no spark i have checked all fuses relays and all are good. i am prducing about .3v a/c and d/c volts and resistance check shows .8 mega ohms for the crank sensor also the end of the crank sensor, the metal cap so to say spins should'nt it be secure? i checked pin to pin from dist to igniter to ECM and only thing found was the shielded wire wraped around the crank sensor wires was shorted to the crank sensor white wire that tee's in to the cam sensor now heres the dumb questions, is the crank sensor bad or is it the shorted wire to the cam and crank sensor. And the last twist is the customers concern was stalling at 50 MPH then i left it over night and now no start. any help or suggestions I would be greatful I'm a retired mech of 35 years and no tester parts available. Already have changed the coil and plugs thank you
