VIN: 5GTMNGEE0A8114110
This car has Injection Pulse during cranking but no Spark from the coil side.
Previous Technician had even changed ECM yet still problem persist.
Now personally checked for voltage on coil wire during cranking, 1 Earth, 1 Voltage which is constant during cranking, voltage does not drop, and the signal is missing, no signal or triggering.
There are Injector pulses to all the 5 cylinder during cranking.
When cam sensor is unplugged and you start the car, holding the key at crank position, you continue to see injector pulses but no spark at the coil side.
Please need advise what else should be checked.
No Scope Is available, only DMM.
No Passlock Lite On.
Had Ignition switch also changed and relearn was done successful.
All Coils were unplug, and tested one by one with the hope that may be one might be stopping the spark driver in the ECM, but yet no sign of triggering was notice, all earth going to the ECM was checked too.
Thanks.
