Looking for some help. 2000 TJ with the 4.0 auto. Before I got my JK this was my daily driver. So it has sat for about a year, but did have the occasional start up and drive around. At that time it did run rough and once in a while it would want to stall out or throw a NO BUS dash code. It always started though.
Recently I began to do some maintenance in it and it won’t even start. It will turn over but not start. The plugs and coil packs have been replaced. Gas is fresh. I can confirm that it is getting fuel. But it doesn’t seem to be getting any spark.
Any chance the Camshaft, crankshaft sensor is bad? What about a bad ECM?
Thanks for any help.
