Ok....car ran fine until son went away for 2 weeks. Came home...car sat in cold but under a cover. tried to start but no joy...
so he first noticed that there was a very weak intermittant spark. So, new rotor arm and Dist cap. Still no joy. Then bought a new coil. Still no joy. I arrive home to help...checked we have very good 12.5v on one side of coil, and to eliminate earth issues i ran a lead all the way back to the battery from neg side. Still no joy,,,now no spark on any plugs. Across the coil there is an amp module which bolts to the side of the distributor. Not really knowing what it does, but as we've checked all else..bought a new one today. Still no spark. I also took a plug lead and ran the lead direct to a plug...so direct from coil to spark plug...still nothing???
Coil does get ever so slightly warm..but only just. Checked that we have correct terminals on coil... the earth strap is connected to the engine.....the car ran Ok 2 weeks ago...
What are we missing????
