Info needed please help

Okay I'm going through my wiring one more time, so I can get my engine running. Does anyone know if the distance betweent the automatic tone ring /flex plate for the dodge magnum's and the manual flywheel for the magnums is suppose to be the same or different. I haven't been able to get spark so it will run, I've changed the CPS on the bellhousing and still I get no spark. I got the orginal flexplate from the automatic that was behind the motor in the begining and it seams that the tone holes in that are closer together than the ones on the manual flywheel would this make the difference, as to why I have been getting no spark. Does anyone know exactly the relationship between cps and the pickup instide the distributor. Any help would be appreciated.

I believe that the pickup in the distributor indicates where the #1 cylinder is, but I'm not 100% sure on this. It has been a while since I looked at a manual regarding how this stuff works.

What year did the motor come out of?

I'm assuming that you are using all the electronics for the motor out of the same car?

Did you hook up the check engine light, and have you checked for any codes stored in the ECU?

Everyhting is from a 93, except the flywheel which is a reman from a 94. and yes I am using all the electronics that came with the motor except for the body wiring I cut and soldered the wires I needed from the truck harness to the jeep harness such as power,speedo, and check engine light. I never disturbed the wiring from the powertrain module. I get a fault for no crank signal. I seem to have power going there to the distributor and the CPS. I changed the crank sensor to the one from the 94 because the one from the 93 plug didn't match. The fuel pump primes but now that the other sensor is in I don't get voltage at the coil when the the pump primes or the injectors before I did. I know it's probably something simple but what is it. I'm going back through all the wiring again for a tripple check but I don't think I will find anything there.

If you aren't getting power to all that stuff, I would be checking your blue (assuming it is blue like most of the Chrysler stuff from that era was) power feed wire. This should come from the ignition switch and power up all that stuff and your ECU should be completing the circuits with a ground.

I'm at work right now, so I can't look at a service manual to give you more advice. The system is really pretty easy though.

I have ignition power going to the blue wire, on the jeep it was white and green or something like that. I have power going to the CPU and to the cps distributor with the key in the on position, I haven't checked in the crank position yet I will do that tommorow but I assume that since the blue wire is connected to the power at all times from the ignition in start and crank there is power there on cranking. That's why I wondering if it is something as simple as the flywheel is still wrong or something. I'm seriously lost here I've been in and out of the wiring for 2 weeks and still seem to be getting nowhere. I still have no spark, I'm almost at the point of taking off my tranny colting on the flexplate and a torque converter and seeing if it starts, and if it starts it'll be the flywheel that is the problem, I know that the timing marks on the manual flywheel are about 1/4" furhter apart than the ones on the automatic, could it be that simple as to it being the problem or isn't it. I also know that the manual flywheel has a bigger diameter tone area than the auto maybe that is why the timming marks are further apart. I'm almost so fed up I should have went small block chevy, but I was to cheap to buy more adapeter than just a dakota bellhousing.

You may be applying power to the blue wire, but it sounds like the power isn't going to everything it needs to be going to. Like I said before, the coil and injectors are supposed to be supplied with ignition power and the ECU gives the injectors and coil the ground. If you are saying that you don't have any 12v power at all those things that would be the place to start.

I found my problem If I never ripped rhe harness apart from stem to stern, I would have never found it. when the morons took out the motor and tranny out of the truck they cut one of the wire sets going to the o2 sensors, I didn't think it was a big deal at the time, but if I never searched ans searched I would have never found it, The cut the wire back far enough as to where the cut the sensor return wire to cps, speed sensor and o2 sensors. It probably would have never happened if chrysler in the first place didn't run the wire all the way down there just to junction it off to the rest of the sensors. It really pissed me off because of the fact I've been trying to figure this out for weeks, but OH well just my luck, now for the next problem see the want adds. Thanks for your help.
