i have 1998 camaro. and my orignal engine went bad. so i bought another camaro that was wrecked but drivable. so i swap the engine with my orignal one and theres no spark. i checked all grounds all conectors. but nothing. checked all fuses. i dont know whats wrong. this is not my first time swaping an engine in a camaro....please help. anything else you guys can think off?

 

Bad ECU???? or lack of coil??? did you check coil? is it trying to turn over at all or whats up?

 

Id you use the computer/ECU from your car or from the donor car. Where the cars the same year? The security system check for the vin number in the computer.

 

thanks for replys. could it be bad ecu? ive changed the coil pack..still no spark. its cranking, but no start...it came out same year camaro..except the parts camaro was auto tranny. and mine is stick. could engine have diffrent sensors causing it to have no spark?

 

Are you using your ECU or the one that came out of the Auto?

 

i didnt change the ecu..meaning im using the manual tranny ecu that came with my car

 

what yr was the doner car?

 

So you switch the wiring harness and the ECU? Is the fuel pump turning on? Are the fuel injector pulsing? If you have no spark and you are getting fuel your plugs should be wet. Any lights on in the dash that are not normally one?

These are not just random question. If you have everything except spark it limits what it could be. If you do not have one of the others then that leads us in another direction.

Craby,
he said in a earlier post they where the same year.

 

Gorn he said he is still using the ecu that was in his car not the donor ecu

 

the donor car is a 1998 camaro. and i have a 1998 camaro. all i did was change the engine. orignal harness and ecu is still on my car. i have fuel pressure in rail. wet plugs. fuel pump turns on. everyting works except the spark...i did however change the oil pressure sensor because my conector did not fit the sensor....im thinking of changing all the sensors..good idea? or could it be a ripped wire?
