Would it be the ASD?

I have replaced the CPS, has fuel pressure, turns over.


Doesnt have a spark at the plugs or distributor.


HELP! May be selling it and it needs to run when I sell it

Thanks

Sounds like the coil to me, its always the second place to go if the cps doesnt fix the no start problem.

ASD relay may have something to do with it?

And well the weird thing is it cranked up and idled just fine before I replaced my t-case. Had problems after i fixed everything.

While changin the transfer case, did you pull a wire, sensor, or ground that you could have looked over? And btw what does ASD mean?

I agree with 89 xj stroker. Test your ignition coil. They can be tested with a meter and a manual. You test them for both primary and secondary resistance values.

Nah, I pulled wire for the interior but that was all intrior dome lights and already non-working wires.

Alright thank you! I just dont understand why I would have no power to the coil after a month in the garage working on the transfercase..

I did remove all of the A/C and Heater equipment but I thought that all of it was on its own power

I found out the problem I think... When I took out the trans, I cut off the ring on the flex plate so I could see more of what I was doing when installing the trans again..

I read that the CPS is a magnet and needs to have a magnetic field to start the vehicle, which the other part to the magnetic reaction is what I cut off.


I wonder if I can cut a small piece of metal and somehow secure it to the magnet to get that all work again

The ring that sticks out and has a bunch of notches in it?

You need a new flexplate.

Yes, the CPS is a magnet and the magnetic field is VERY small. I had my old CPS (still working CPS) and plugged it up and set it to the closest clean metal I could find. I laid it on that piece on metal, but still no result.

I'm thinking I could somehow get around that. Somehow securing a piece of metal to the CPS and trick it into thinking that the ring is still there.



After I did the CPS stuff, that still isnt all of the problem. It probably helped the problem, but now I'm thinking its the Ignition coil. Theres no spark from the coil to the wires..

You NEED a NEW flexplate. Fix it right.

Honestly the Jeep isnt worth buying something new. This is FARR from being a Daily Driver. It has been trashed from the previous owner through the mud and woods.

The Jeep its self is a ghetto homebrew.

89 xj stroker

No, you really need a new one. You cant trick the cps into thinking the ring is there. It uses the notches to know the rpm and when to fire which cylinder. In order for it to run correctly, you need a new flex plate even if it is off of one at the junkyard. If you get one for your jeep, make sure it goes on in the same position as the old one came off.

Just when you think you've heard everything............LOL

There is a way around your flex plate problem. Hesco makes the 4.2l injection kit that kit uses a sensor on the harmonic balancer for reading the crank. all you need to do is purchase the balancer for the auto trans and the sensor you can get at auto zone. no need for the whole kit or to replace the flex plate. simple as that..... hope that info wasn't to late..
