02 Corvette no spark or injector pulse please help
Ok I got my motor back in 2 weeks ago an I have no spark or injector pulse.
Here is the info everyone in gonna ask first I know. Yes the ground is on the back of the head an the ground is on the driver side of the block where the body ground connects also. An the ground is connected on the passanger side with the battery ground.
At the connector for the coils the pink has power an the wire below has ground. Also at each of the injectors I have power there is just no ground during cranking.
During the process of removal of the motor the 3 wires to the crank position sensor got broke but I replaced it with a new connector "ebay replacement part". There are 3 wires that go to the cps green "positive", yellow "negative an a blue "feed to the pcm". I tested the green an the yellow an they have power an ground on both sides of the wire where I reconnected them so I know the sensor is getting voltage. The only way I know to check the blue wire is with a high impedence test light that I don't have yet.
I replaced the sensor today with a new today also with no changes. I have monitored the pcm with my HP Tuners Scanner an then used a tech 2 today an when the motor is rotating over there is no RPMs being read via the pcm.
Does anyone have any ideals to help me out please
