Hello all, Did a search and nothing turned up. I have a 1990 Cherokee with the 4.0 and auto transmission. It has always had a starting problem but since about 3 months ago, it has gotten harder. It is not the battery or charging system. I have read about the crank position sensor needing to be slotted to get as close to the flywheel to get a good signal. Any clues as to what else I need to check? It gets fuel and turns over good. Thank you for any help you can offer. Ron
