Well I went by what the Chilton's book said both had power on the power side and then with someone in the car both gave a signal on the output side.
I also did some more online searching and it apears like Chrysler switched computers in 02 to a more advanced one and I need to switch the cam gear and The flywheel (I didn't switch them in the swap) Something with they have more teeth so the computer can make the car more fuel efficient. But the old computer cant read the different curve of the new one and hense don't start.
Anybody know anything in more detail or can confirm that this is indeed what is wrong

Flywheel is different, Cam tonerings are different, and the Cam Sensors themselves are different...(Although there is a slight difference in appearence, I really dont know for sure if they will function properly or not)
As Kevin just mentioned.....Do you still have the old motor???? Buying this stuff can get expensive, and most junkyards wont "BREAK-UP" a running motor.
Since youre dealing with something used...with no real way of VERIFYING what year or system was used...The difference in computers is this... SBEC = Early.....NGC=Late...
SBEC has 2 big white plugs at PCM....NGC has 4 "Black " plugs at pcm.

We aren't ALL thieves, We're Just trying to make a living like everyone else , So Have A Heart.
If You wanted Dealership Service, You wouldnt Go To "Discount Quik Lube" , So why did you Walk into a dealership Expecting QUIK LUBE PRICING????
Ma'am, It costs so much money, because ...I CAN, And you CANNOT, And It matters Not to Me, Because I HAVE A RIDE HOME.
3/36 Does not mean 3 years and a day, or 36,001
I do still have the old motor i'm a bit reluctant to get rid of anything until the project is complete. I also do still have the donor car as it was a salvage vehicle. I also did double check it and it does have the four black plugs so it is a NGC and the old car is a SBEC.
I tried starting it with out the cam sensor and still the same thing
So It sounds like i am going to have to pull the motor back out of the car and change the flywheel and cam gear. Nothing like getting some more experience pulling a motor.
