Try using your test light across the coil while cranking. It should blink..... If you are still getting power to the coil, that would indicate that the crank sensor is indeed sending a signal, if it weren't, the pcm would drop the ASD relay.

Also check and see if you are getting injector pulse. (I think you can use the same testlight method...)

Do you have fuel pressure? Does the pump run while cranking?

 

I have good fuel pressure and plenty of fuel goin to the motor. When I get home I will check the crank sensor and injectors. I know the injectors have power to them not sure on pulse. I know the crank is getting 5v reference and ground. So if it doesn't send a signal today then I'm gonna get a mopar one from the stealership. Also yesterday didn't realize the upstream o2 sensor was hooked to the asd relay as well. So I bypassed the asd and tried to crank and got nothing, but ended up finding an o2 I had in my tool box that fit so I hooked it up. I hope I get this fired up soon, got a new job sttarting june 6th.

 

Ok so, figured out a lot of things over the past couple days. Well, the pcm that came with the motor is actually for an auto. So I got a 98 pcm from a manual. The motor is a 96 however the ckps plug is for a 98 auto. (Huh????) So, the injectors are no pulsing, I'm getting "no bus" with both pcms. The 98 should have the ccd bus system correct? Could it be a faulty pcm? I cleaned the connectors.
What sensors are required for the injectors? They get 12v but no pulse on crank. Still have the same spark issue as well, pcm is not switching ground.

 

injectors are mostly controlled by the cam sensor. If you have power while cranking at the coil, and injectors, that implies that the PCM is getting signal from the various sensors, I think the trouble might be the harness pinout is different than what the pcm thinks..... You are putting this in a jeep, right? Also, I do believe there IS a difference between manual, and auto crank sensors.....

 

Yeah, its going in a Jeep. Im using the Jeep gray plug that goes into the PCM. I spliced in various wires into the jeep harness from the dodge such as fused b+, ign. switch output, etc. I've got a manual CKPS for a 98 hard wired in due to the plug difference. I've tried a 96 one and 98 one. Just checked and with the new PCM the crank, map, ect sensors are not getting 5v, instead they are getting .3v (checked on crank and key in run position). I put in a new cam sensor the other day. I've checked pinouts between the years and they appear the same. I do however have a random wire on the black plug at the PCM (C1). Its a dark blue wire in cavity A14. It went into the 3 connectors that went to the dodge fuse block and big square white plug.

So far I've traced the wires I spliced by the cavity instead of color/tracer. So far its right. I will trace the wires to the crank, cam, ect. here in a bit from the actual PCM pinout and cavity.

 

I'm betting it's a wiring issue, probably because of the 96-98 difference in PCM pinouts.

Edit: check and make sure the ASD relay/circuit works,

 

I've checked all my wiring, checked the pinouts, all the same except for the CCD system and the generator field source is added in at the grey plug. I'm thinking the PCM is bad. Testing between the two pcms, the 96 pcm will send 5v out to the sensors, the 98 only puts out .3v to .1v. The 98 is also getting "no bus" and its not communicating with my scanner, where the 96 will communicate atleast. I'm almost certain its bad, and if I can find a good PCM with a manual or somehow bypass the trans stuff in the 96 it would start.
Anyway to fool the PCM into thinking there is an auto trans there?

The ASD is working. My buddy and I have been through this wiring probably 6 times by now. I'm about burnt out on this, I just wanna drive my Jeep, I'm sick of using my wifes explorer and having to take her to work if I have to do anything that day.

 

There is no difference in wiring between the auto, and manual. Its all programming. If the PCM expects an auto, it will set some codes for various things, but, you can ignore those for the time being, just to get the engine running. Once you have verified that it is indeed the PCM that is the issue, you can worry about programming from there. I don't know if Hemifever could do you up there or not, would have to have a chat with him.

 

Hmm, I was under the impression/told that an auto pcm wouldn't run or start if it didn't sense an auto. Well hmm.. well, back to the drawing board. I honestly don't know what to look for anymore. Maybe the pcm isn't getting a correct signal from the ckps. I'm not sure..
Anyone wanna buy a jeep project?? Hahahahaha j/k

 

Nope, there are a fair few folks on here that have done the manual conversion, but are still running the auto PCM.

What year all all of your various components? (including the jeep....) and what engine did it come with originally? (I know this information is prolly scattered thru the thread.... but, would like to see it all in one place. )
