Also check your ground cables ;)

Thanks bbforks. Ok located relay,appears to have possibly gotten hotit has asmall round circle of rust on side.Idont have a spare to change out, wondering if i could swap out with one of other relays.There is another one justlike it not sure what it controls,tried matching wire color on schematic no luck.I am currently checking out distributor wiring.Thanks for quick reply.Iam a newbie,my first post.This is cool stuff

I would check the wiring at the distributor- there's a tach sensor which the ecm needs input from to turn on the lp system. Also the no spark issue would be a dist issue if there's power to the dist.

The lp relay is under the fuse panel, behind the panel by the left step - as seated on the machine
