Question about 1998 Jeep Wrangler
1998 jeep wrangler tj sometimes starts up on the first try but seems like when it gets up to temp and you turn it off for afew minutes you have to turn it over twice to get it to crank up. i think i've tried just about everything. please help
There are several things you can do if you haven't done so already, Check voltage at ignition coil, as soon as the engine starts to turn over there should be voltage. If not, the crank sensor is not triggering the ECM quickly.... on 98-99 wranglers, this was a problem area. Check terminal connectors at the ECM, clean and secure, another area of concern.The module on the side of the throttle body is the air idle control 'motor' as jeep calls it. Over time they tend to carbon up and it results in bad air/fuel mixture and yet fails to send a fault code, you can remove & clean also the O2 sensor in front of the cat. convertor.remove & clean. Check fuel pressure, you should have some residual PSI. Treat fuel system with a good treatment...I like the Lucas products, their fuel system treatment and injector cleaner burns hot & clean.
I hope these suggestions help...and the wrangler returns to top form...good luck.

I have a 1997 jeep wrangler with the 6 cylinder. it does the same thing. the check valve in the fuel rail is bad, i did a fuel pressure check and found out i had no residual pressure

Check your oil level on your oil stick. Sometimes the vehicle tells you that he needs a little oil or an oil change.
