my 92 yj wont start after auto swap the cps was different the maual was squre and the new one is round but doesnt seems to fit correctly.. . does it pu signal fron teeth of flexplate or the flat round part of flywheel ?? were do i get cps relocate kit

When I swapped a 4.0 into my 90 YJ in place of the 258 I had to do the whole CPS relocation bc my older flywheel didn't have the correct notching to be read by the CPS. I went with Advance Adapters kit AA part#716012, It was like $250 or so and did the trick.

did you drill and tap the tranny? what did the flexplate come from? the distance could be off from the cps to flexplate. It picks up the signal using the spaces in the flexplate. What year did the tranny come from we need the whole story. I personally would try to figure it out rather than run a cps kit

Have you bypassed the neutral safety switch? I think it just needs to be grounded.

edit: If it cranks then this is not an issue.

yes it cranks. the tranny comes from a 99 tj tf 999 has factory hole in it. . by the other threads here it says to use a flexplate from 90 yj but i really dont remember seeing any notches on it so looks like time to relocate. i have tried diff postion on tps. we are not getting any spark no matter were we put it. should there be power to the wire when cranking .

There are two different types of crank sensors for the 999. I ran into this once, does it ever act like it is trying to fire? You might not have the right one, I would not relocate as it is $$$. You just need to make sure that you have the right combination of sensor and flywheel.

'90 YJ doesn't have fuel injection so I'd be surprised if it had a CPS...

the flywheel you need should look something like this. the CPS is triggered byt he square holes in the sheetmetal ring around the perimeter of the flywheel. a 90 YJ has a 4.2... us the flex plate from a 91-95 or 97-99 yj/tj

i did swap from threADS ON HERE AND THEY SAID USE A 90 FLEXPLATE.. THANK GOD FOR THAT RELOCATOR KIT BECAUSE YOUR RIGHT . 90 IS FI SO THE FLEXPLATE DOESNT HAVE AND GROVES/ KNOTCHES ON IT ASO THAT THEY WRONG FLEXPLATE IT BOLTS UP FINE AND INGAGES FINE BUT HAS NO KNOTCHES FOR CPS TO PU SIGNAL
