OK, crank sensor it was. It starts and runs. Now that I dumped all sorts of starting fluids and old gas down the tube to attempt to start my YJ, I think my injectors are dirty. I get a little "bucking" now and then while driving. I have to admit, when I took the intake off the body ( what 25 years ago I would have called the carb), inside looked horrible. All black a sooty and gummy. I also suspect that gas I poured in there was perhaps 2 cycle mix.
I already have replaced all the electrical components, so therefore I am assuming I am having a fuel issue now.
Any ideas on how to clean this area?
Thanks all, you've been a wonderful resource so far.
