I have a 1989 jeep Cherokee limited I changed the crank sensor I have spark rotator cap is old but working and I'm pretty sure I have fule what else can it be?

When it comes to diagnosing and fixing problems on the older XJs, Cruiser is king.

check your wires to your starter solenoid

Thank you I'll give it a try

Turns out my fule pump went out after we changed the sensor I now know how to remove my gas tank ! No wonder I was getting good mileage it was barely dripping
