97 wrangler won't crank
- Thread starter Jblauser
- Start date
What do the headlights do when you turn the ignition switch to the Start position??? If they shut off you either have a weak or defective battery or there's a bad/dirty/weak/loose battery connection.
You can take a long wire. Hold it against your battery and let the other end tap the starter. A good battery test
do you have a standard transmission? might be a failed clutch safety switch.
its been a while since I had to do it but you can easily bypass the clutch safety switch by pulling a fuse to test the theory of possible failure if so. im not suggesting this method as a permanent repair though.

Post some info on which specific Jeep you have 2.5l/4.0L 5-speed or auto. This will help us help you.
If you do have a 4Cyl 5 speed use this to trace down power from the Ignition to the starter:
Are you sure your actuator switch didn't break again?
How about the starter relay?

When you turn the ignition switch to start the engine; test the ignition switch voltage at the starter solenoid terminal that actuates the solenoid.
What is the voltage or is there any present ?
IF you jump the starter and it cranks sometimes... verify as JB posted above.

Yeah I just realized his title says "no crank" but then he states "If you jump starter. It will crank or turn over. But will not run."
He needs to change the title to Cranks turns over but will not start.

Initiatly, it would not turn over. But sometimes would. I have fixed that problem, put in a whole new relay on fuse block. It now turns over, but will not crank. I changed the crankshaft sensor. Checking fuel pump and solenoid this afternoon. The vehicle is 97 tj, with automatic transmission. Straight 6cyl 4.0 L.
You may be confusing folks here. Cranking and turning over are kinda the same thin, at least to me.
Sounds like it’s a fuel or spark problem. What happens if you squirt a little starting fluid down the throttle body? Are the plug’s getting spark? Is there fuel pressure? Sounds like you’re on the right track with checking the fuel pump.

Found the problem, it was the ECM, on the right side of fire wall. It now cranks up, runs with the key. Everything is working as it should. Thank you for all assistance. Once i hooked up a computer on OB2 outlet, and ran diagnostic. She cranked right up and purred like she used to. She required being put in power train mode on computer. New ECM installed and cranks/runs everytime.
Funny I was going to say that.
Awesome I glad you got it figured out!!!!
