Crank no start issue on a c10. Customer was driving down the road, said it spit and sputtered then died. Towed it to my shop, checked to make sure it had fuel pressure. No fuel pressure. Replaced fuel pump and primer pump. Gets 40 psi fuel cranking. Still no start. Check codes, none. Run injector solenoid test. Passed. Ohm out crank and cam sensor both test good. Measure voltage at injectors during cranking. 0 ac volts. Thinking the injector drive module went out, got new ecm from cat. Still crank no start. Have battery power at ecm pins #52 and 53 and pin 70 with key on. Have grounds at 65 and 67. Just to be sure I wasn't wrong I replaced crank and cam sensors. The truck will run off of starting fluid until starting fluid runs out. Im losing my mind on this one. Any help is appreciated.
Hi there. Did you ever resolve this problem? I'm having this exact same issue with a 2000 C-10 and am pulling what little hair I have left from my head.
