86, 2.5 issues. I NEED TO DRIVE THIS THING!

Recommended Posts

Yesterday I bought an 86 comanche, 2wd 2.5 4 speed. PO said that it lost pulse at the injector. He replaced the injector, and fuel pump but didn't go anyfurther. Got it home and got to look at it for a min this evening. it won't hit on starting fluid, so I put a spark tester on it. Nothing. I have no pulse, and no fire... his back story was, it died on him. he let is sit 15 mins, was able to start it and get home. turned it off, and it never started again.

Anyone have a starting point for me?

would that have anything to do with the injector not pulsing? its an obvious that the coil can be suspect for the no spark..... just didn't know if there was anyway to check it without replacing it? or if there was something else to look at first that could cause loss of both?

no way to test without replacing though, and I'm not in a position to throw parts at this thing.

Oh, yes there is a way to test the CPS.


Renix CPS Testing and Adjusting
Renix CPSs have to put out a strong enough signal to the ECU so that it will provide spark. 
Most tests for the CPS suggest checking it for an ohms value. This is unreliable and can cause some wasted time and aggravation in your diagnosis of a no-start issue as the CPS will test good when in fact it is bad.
The problem with the ohms test is you can have the correct amount of resistance through the CPS but it isn’t generating enough voltage to trigger the ECU to provide spark. 
Unplug the harness connector from the CPS. Using your voltmeter set on AC volts and probing both wires in the connector going to the CPS, crank the engine over. It won’t start with the CPS disconnected. 
You should get a reading of  .5 AC volts. 
If you are down in the .35 AC volts range or lower on your meter reading, you can have intermittent crank/no-start conditions from your Renix Jeep. Some NEW CPSs  (from the big box parts stores) have registered only .2 AC volts while reading the proper resistance!!  That’s a definite no-start condition. Best to buy your CPS from Napa or the dealer.
Sometimes on a manual transmission equipped Renix Jeep there is an accumulation of debris on the tip of the CPS. It’s worn off clutch material and since the CPS is a magnet, the metal sticks to the tip of the CPS causing a reduced voltage signal. You MAY get by with cleaning the tip of the CPS off. 
A little trick for increasing the output of your CPS is to drill out the upper mounting hole to 3/8” from the stock 5/16”, or slot it so the CPS bracket rests on the bell housing when pushed down. Then, when mounting it, hold the CPS down as close to the flywheel as you can while tightening the bolts.

just realized that the ignition switch is touchy. when in the ON position i have to wiggle the key to get the buzzer to come on. another possible culprit... I also can't here or tell if the fuel pump is kicking on. The PO did say that he had it checked, and that it was good.
