So this guy calls me and my brother saying his truck wouldn't crank. We are mechanics so of course we went over there but we are lost. First it wasn't getting fire so we checked everything and found that it needed a crankshaft sensor that fixed the no fire problem but now it will not start. We have replaced crankshaft sensor, icm, solenoid, plug wires, distributor cap. We have checked fuel pressure it has 60 psi compression is completely even around all cylinders and everything is getting correct voltage. We know it's getting fuel to engine because it's fluffing the plugs out. Any ideas? Our heads are rattled
