Hello everyone. New to the forum and have done quite a bit of reading in the past till now. I searched for my issue on the site and couldn't find anything that runs right along with this problem.
I have a American Lincoln 7760 sweeper/scrubber with a Ford LRG-425 EFI gas W/propane upfit. Long story short is someone left the key on accessory overnight and came in the next morning to a dead battery. This machine ran flawless beore the dead battery. They attempted to jumpstart it, but would not start. It has a crank/no start condition, and is not getting spark. No voltage to the coilpack either. The engine has an engine performance module with a black and a grey plug. That is the main controller for the unit. I cannot find a good wiring diagram for the engine or the pin out for the ECM plugs. I also cannot find a troubleshooting guide within the shop manual for troubleshooting ignition related problems on this thing. Ive reached out to a few Ford industrial distributors with little luck, other than a shop manual which I already have. Any help is appreciated!!!
