Hi I am a newbie to this forum but need some help with the 1985 GM V6 engine

a mate has got this engine in his motor, he parked it up went to bed and it wouldnt start the next day, checked the engine and found there was no spark, we have replaced the Coil Pack, Dizzy Cap & Leads and there is still no spark.

any suggestions as to where to go next
many thanks

I had a simular problem a simular problem with my mates 1.2 8v engine in his Nova (it was a 1985 model) and it turned out to be the hall effect sensor... We changed everything as above including new plugs and it still wouldnt do it... Didnt cost much for a new one from Vauxhall either... from memory the hall effect sensor fits on the end of the rotor arm, then the internals that the dizzy cap go on top off fit on it.

Id say strongly its that going on the experiences gained from that nova. Common fault i was told by vauxhall.

How did it go then?

The immobiliser is often connected to the ign, starter, and fuel pump!! the latter two are easier to diagnose!

i doubt a 1985 Gm engine would have an immobiliser :lmao:
