Cam sensor is reading good on Renix Engine Monitor. Though I didn't have one for years maybe I should try unplugging it. I'll check on the bellhousing bolts, also getting an O-scope today so I'll see what the pulses look like before and after the harness.

I have now tried 5 sensors, I'm getting .2-.3v AC from them. My CPS's in the past have always been around .2v AC and the Jeep started fine. I tested the resistance to the ECU and it's .1 ohm both sides. I got another ECU today, and same result - CPS crank fault on Renix Engine Monitor. What...

Just tried another CPS, and borrowed a different multimeter to be sure. No spike, 0.0 on crank. Any ideas? I'm going to make sure the flexplate is still there

Have an 89' cherokee with a no-start issue. On crank it will try to fire for half a second but no dice. I've installed a few CPS sensors, and they are not reading any spikes on AC voltage but it could be my multimeter. Renix Engine Monitor does say CPS fault. Is there anything that would be...

You should definitely check the distributor and rotor condition, coil connections all that stuff. Check your ballast resistor if you have one, go ahead and bypass it and see if that makes a difference. I wouldn't worry about the cat, I think it's only a problem when the ceramic matrix breaks...

I've tried airtex and Carter pumps they were both junk. I think one did 10k and another did 40k miles. It's definitely worth sourcing a bosch

I would still replace the pump and filter with your symptoms. It's more likely the cause than the stuff you've replaced so far I think. Genuine bosch only they last around 200k

Have you replaced the fuel filter?

It's perfectly clean, stop screw looks fine. I did find a small leak on the spring side of the butterfly shaft so I will look into replacing the shaft seals I tried adjusting the TPS above and below 17% today, no difference. Still going to replace the connectors or maybe bypass them temporarily

I meant to say I'm running it with the IAC unplugged not the TPS. Sorry for the double posts I can't edit

Awesome thank you! Well I am running it with the TPS unplugged and fully closed. It starts normally now but everything else has gone back to where it was, 1100-1200 rpm idle. It seems like the ECU wants it there Vac is 15-16Hg at idle? Wish I could find a leak. I'm going to replace the...

Well the top and bottom rear bolts were loose, but that didn't change the idle. It really sounds like there is a leak under the intake manifold, but I can't make anything happen with propane. The engine sounds odd to me in general it has a turbo like whine, but you'd think I would get a...

Since I've owned the jeep, it does a good rev on startup then settles down to 1000-1100rpm. In gear it will hold 700-800rpm. I have been through dozens of IAC's over the years and the TPS is currently brand new and adjusted properly. Trying to figure this out I installed a fully extended...

So I moved some wires a little to paint my floor pan now the starter won't engage. Fuel pump primes and everything else seems fine. Does anyone know which wires in particular I should look at? It must have been something under the trim piece by the fuse box. Thanks

Just an idea of the top end for these things - my Renix (4" lift, 33x12.5 ko2's, 3.55) gets 16-17 around town and 22-23 highway. My trip record is 25
