What year, 2 door or 4 door, automatic trans or manual, ZR2, LS or LT?

 

Neutral safety switch. Also I was 180 degrees out of timing.
Reset timing and it fired right up.throwing tcc codes now from new computer. Gonna put old computer back in and see what happens.

 

If you leave the old PCM in the vehicle, you will need to have it flashed to your VIN and the crankshaft position sensor relearn must be performed. Both are mandatory, not optional. If you reinstall the original PCM, nothing needs to be done to it.

 

thanks for the info captain, before buttoning up thedash, i pulled the ign. switch to make sure i was in the right spot. it wasnt. now it will start and die in a sec. gonna piddle with the switch some more to make sure im in the right tooth. tried the thirty minute relearn to no avail. security light is not on..........
mine is a 2001 2dr 4x4 ls ZR2 manual trans.

Thnx

 

 

To find out if an intermittent ignition switch is your problem, get your dvm out and connect it to either the input or output of the switch with a jumper lead and see what youve got when it dies. No power in then its not the switch. Good power in and no relevent power out then its the switch.

When part of the fuse block/dash/etc dies, please report which functions are lost which helps us find the fault.
