If you redid the bottom end, are you sure you plugged everything back in

 

Search FTW!

 

thanks but still have the prob

 

i have change the ecm.coil ckp,dist,cap rotor,plugs,wires,and this still want run turns over but no sparks can someone help me please i tried everthing

 

Merged with your other thread.. Might have something in common...

What have you done to remedy the P1345 code? Have you gone through the diagnosis? What were the results?

 

i really don"t know disconnect battery and the code was gone

 

Disconnecting the battery is not the same as diagnosing the problem. This code takes awhile to come back. The fact that it was there meant that the PCM recognized a problem.

 

i had a guy come over and check all sensor and volt on them and everthing has check out ok throw the gm service compter but no sparks it show no dtc codes

 

you say you rebuilt the bottom end. what did you have done. did you put the crank reluctor wheel back on? and is the nut that holds that tight? had the same thing happen on jasper reman except it ran for aprox. 3 months then died. no spark. found crank reluctor ring loose and not turning with the engine.
