I have searched but cant find a problem like mine.. I have an intermittent no start... It will start fine a bunch of times but once in awhile all it does is click when warm usually.. new battery, starter, relays, cables, NSS cleaned, new ckp, grounds are good. Alt. tests ok It does crank like 5-6 times before it will start everytime but has always done that After it sits for up to 20+ mins it will start again usually.. Really starting to annoy me. Please help

Thanx

 

Have u checked your cps

 

yep its also been replaced

 

Have u replaced your ignition switch

 

yep. Ive replaced most everypart on the motor since i got it from the JY

 

Ignition switch isnt in the motor just to, point out

 

well ya i knew that but yes it has been changed since i got jeep with no keys..

 

Next time it happens, get a meter and measure the voltage directly at the starter with the key in the ON position.

You may be experiencing a voltage drop between the battery and the starter. Should have approximately the same voltage as you have at the battery as you do at the starter. If not, you need to work your way back into the engine bay to find out why.....

 

What method did you use to test the CPS?

 

Mine just had a little bit of corrosion on the tip so I replaced with out even thinking twice

 

Always good to test the AC voltage output, even on a new sensor. They've been known to be bad right outta the box.

 

I didnt test it I just replaced it.. been roughly a yr.
ok i will do that thanx tj
