Hi folks,
Tried to fire up the coach this morning and lots of gas, no spark. Admittedly I have not run it for a couple of months now. 455 with Howell EFI/EBL and a Paterson HEI distributor. All the fuses are good in the Howell and no obvious wiring damage from rodents. I’m leaning towards the ignition module, however no spare. I’m not on the road so no problems there. I’m not sure if Dick Paterson’s modules are special or just stock GM parts. If not I’ll get one from NAPA tomorrow. I did send him an email. Does anyone know if you can run a diagnostic off of the EBL and the laptop to narrow the issue down. In near 12 years this is the first time the motor has not fired up with the EFI/HEI setup. Usually a couple of seconds on the starter and away it goes.
thanks for any insights.
