99 Tahoe 2 Door 5.7L Vortec. Girlfriends car. She was driving it and it just died. Really wants to turn over, but just wont. I get spark at plug #1. I get fuel at the little valve on the fuel rail. I swapped in a new coil and ignition module, no go. Guy at the parts shop let me borrow a Crankshaft Positioning Sensor, swapped it... no go. No check engine light on, security light goes off like it should, fuses are all good.
My next guess is timing or the ECU. Any other suggestions??
