P38A Replaced HG misfire

sandyt · Jan 11, 2016

Gents at the weekend replaced the head gasket on the offside bank on start up have a misfire so have a fiddle about and get a shock off the lead to pot 8 silicon leads by the way so swap the lead s 8 and 6 and get a belt off no 8 again with a different lead so thinking must be the coil pack but not sure how that can be ????
Bit confused any help appreciated

Never touch ht leads with engine running. It can kill at worst, or give you a nasty shock followed by feeling a right tit

Have a look at and rev the engine running in darkness.

The V8 works on the lost spark principal, one cylinder is sparked at TDC firing one is sparked on the exhaust stroke. Coil 1 fires 2 and 3, 5 and 8. Coil 2 fires 1 and 6, 4 and 7.
