brown egg

I've been having a no-start condition a couple times a month. It will crank and crank but if I do it long enough it putters and starts up.

I hear most people with cps problems talking about stalling but it never does once it's started.

I have a renix, I did the tests and I got .1 ohms and 0 volts when cranking. If it's really that bad how could it work fine most of the time?

AC volts on cranking with the CPS unplugged?

What year Renix?
If it were me, I would go to www.cruiser54.com and complete Tips 1 through 5 first as a preventative measure. Might just fix it also.

Note from DJ
Are you sure that you were testing the right connector?

It's an 89'

Yes cranking with it unplugged. My multimeter doesn't show anything at all. I used the right connector.

I've done cruiser54's tips.. Guess i'll put in a mopar and see what happens.

Set on AC volts?

Please be sure there aren't 2 CPS connectors and you're plugged into the wrong one. Here's why:

There was a TSB on replacing the CPS with a different harness. The tech was supposed to cut off the old plug. Many times they didn't.

Yes set on AC volts connected to the unplugged CPS. I followed the connector back and tried again it's the right one. The JEEP has been running great though.
