no spark... urgent please

Post by Mk1Sport »

as the title says im not getting any spark

ive already tried swapping the polarity of the vr sensor and it didnt help.

i also tested it with a timing light to see if everything was working, and after the motor turned over there was a very loud bang and yes the timing light did flash when it happened

any suggestions?

No spark at all indicates an EDIS problem so let's get back to basics:
- take the MJLJ out of the car completely
- take all the plugs out and all but one off the ignition leads
- rest the remaining one on the lead on the block, so that the outside of it is earthed
- turn the engine over - any sparks?

Assume no, so....
- check the wiring at least 3 times
- check earths
- (silly question - you have got one of the teeth missing on the trigger wheel haven't you?)
- measure some voltages during cranking - 12v on EDIS pin 8 and on centre connection of coil

Report back...
