Crank Position Sensor
Ok, just replaced a crank position sensor on my sons 1993 5,2 V8 due to stalling and eventually no start, now it misfires really badly and wont stay running without keeping the foot on the gas, I have double checked all connections and checked plugs, dizzy cap etc, WTF could it be now.
Appreciate any help guys...

same thing happened to me, "not suprisingly" i remember adjusting some cable that did something with the transmission, it was a really easy fix so dont go buying a new tranny. im sure some one else here can give you details... as far as the misfire, i just got new spark plugs and new cables, luckly my uncle has a computer so it told us witch one was misfireing so i only needed one. youll figure it out

i had the same problem recently. but with it running ****ty and stalling the plugs were fouled and had aton of junk on em. my best advice before u do anything is run some seafoam thru it. thats what i did before doing a full tune up.

Is it throwing any codes? That is actually where you need to start.
Also disconnect the battery for a min or so. Easy and free to start.

Mine had the same problem, it turned out everything was due to the pickup coil. Theres many names for it but thats how pep boys will find it for you. $30, it's in the distributor and takes bout 20 minutes to replace.

Well I thought I had nailed the problem to the CPS the one that I installed was a BWD brans purchased from Advanced Auto Parts, I took the newly installed sensor out and installed a Duralast sensor from Auto-Zone, low and behold it cranked right up and runs great. So looks like i`ll be giving the BWD brand a miss next time.
Also if anyone is going to do this job on this particular vehicle I found a nice little Pittsburgh ratchet from Harbor Freight only about 3" long and the 1/4" Hex Allen Key fits in it perfect, you can get that little ratchet down in there just right, made it a 20min job..
Thanks for all your help guys.
