Well then that's good to know. I could drill a few extra Holes to test this theory in one of the extra distributor plates I have. Each a degree or so apart and see what happens. You would call that a "hot cam" then? I'm no professional mechanic so the numbers didn't mean much to me. I just...

I got to wondering about a cam upgrade my older brother did on his 4.0. He ended up having to drill a hole to move rotor placement to make the darn thing run. Hope I don't need to do that as its stock but...I did find a cam spread sheet which says the 96 and up cam changed...

I suppose just for peace of mind I could stuff the automatic back in tomorrow just to see. It would answer that question at least.

I know I had to jump 2 wires together so it thought it was in neutral soi would crank over..but are the timing windows different on a 90 flywheel?

Chain has almost no slack as I expected as the motor has less than 60k kilometers on it. So just to eliminate the possibility I replaced the cap and rotor and plug wires....I was going to anyway. Found to have spark on 3 and 4 only but still not at right time. So back to an earlier...

The coil sparks multiple times per revolution just seems to not be speaking when it should

OK I got a 3 wire with plastic cover and stuffed it in and still not much has changed. So I decided to put the timing light on coil wire. And found is sparking away but nothing is getting out except on cylinder 3. getting more confused as I go

here is a thought. can I cut off the plug for The 4 wire distributor and put the 3 wire a plug on itand see if that works. just need to know which of the 4 wires I don't need

If I don't figure this out soon I head a 360 will drop right in haha. Don't don't want to but might be the way do go of this thing don't run soon

ok....now im confused. when the distributor is installed as per directions then I have no spark....if its set in 1 tooth off it sputters...so to my understanding, if correct, then things are to far out of sink to work properly or there might be a short somewhere?

Didn't get a chance to work on it yesterday with all the rain. Maybe today if I can find a timing light

I have now. Going to go pick up a timing light just to be sure it's trying to fire some where close to where it should

What position is the sensor in when installed on that 98?

I do apologise for the confusion however as I believe from wica that the zj stopped this body style in 98 so it must be a 98

ok just for clarification. the flywheel im using is from the 92 and so is the sensor....all electronics are as well as intake and header. just the block and head and internals is from the 99....it might be a 98...not sure exactly...was a totaled zj. but it did run before I pulled it. the...

ok...so here is what I have so far. if I disconnect the crank or cam sensor it will throw a code for it. if I move the plug wires clockwise one then it spits and sputters...if I move them the other way then then it sparks but just to soon. so why is it if I put it all where it SHOULD go I get...

Now the sensor in the distributor is for the injector timing only, correct? If it is not functioning will I still get spark provided the Crank sensor is working?

T he sensors in the distributor do a pear to be aimed at a different location now that I look at them side buy side. I will do some testing on injectors when I get home and update when I finished.

Yes it is on TV on compression stroke and valves closed. Pulled valve cover to be sure. Compared distributors from the 92 and discarded 99....and it appears the 99 sensor is positioned in a different location than the 99....would it stand to reason that the crank sensor and flywheel would have a...

OK so here it is. Have a 92 X sport with cracked block but still ran. Pulled a motor from a 99 ish Zj which also still ran. Pulled the intake and exhaust off as well as distributor because that stuff would not match up. So what I have now is a 99 block and head and all internals with 92...
