OK I done everything the tab said and still no spark or injector pulse anymore ideas I have seen some people with this same issue on some threads on Google but never put a answer on there for what fixed their problem or they just never got it fixed any more help or ideas would be helpful

So, do you have a CPS signal at C1 and D1? One probe on each with the meter set to aC volts?

ck12sk

Yes what are the reading supposed to be in think they may be too low

cruiser54

SHOULD be the same reading you get at the CPS connector.

ck12sk

Ok I am getting .o5 aC volts at the crank sensor and at the c1 and d1 pins at the ecumenical anything else it may be

cruiser54

.05 is WAAAAAY too low. Should be .5.

ck12sk

Let me check again I may have red it wrong the crank sensor is a new Napa one couldn't get one from the local jeep dealer said they was discontinued

ck12sk

Would the flywheel have anything to do with it reading to low

ck12sk

Would the fly wheel have anything to do with the voltage reading to low

cruiser54

Not the flywheel. Check the cPS again and look into doing the modification to it in Tip 7.

Got it running today had traded for another computer and it fired up after a few minutes of cranking I guess my cousins computer was messed up also not sure but it idles fine but backfires when u give it gas and acts like it is trying to dye until u Rev it up at a high rpm

zebvance

one step closer! Sounds like the backfiring and dying thing may be because the TPS is not dialed in.

ck12sk

I think it may be the fuel pump my buddy's 2.5 wrangler done the same
When the his pump went out I am going to take my fuel pressure gauge home from work today and test it

zebvance

Sounds like you got a game plan. The TPS can be tested through crusiers tips also if that doesnt work.

ck12sk

I have done that test and it tested good I just purchased it last week thinking that it was why it wasn't starting up
