Scott205 Posted May 7, 2013 Report Share Posted May 7, 2013 HI guys, Had a major issue with the original wire from the CKP to ICM going bad a few months ago. Being a teacher and going through a divorce I just haven't had time to replace it, and the first shop I gave it to (I used to trust) tried to tell me I needed an entire engine harness rather than just the small one. I have replaced the 92 3.4 DOHC with a crate 97 (and intake from a 97 Monte). I couldn't manage to get the wiring off from the bottom (just not enough space between the engine and Tran. So here is my question. Do I have to take off the intake (seems the logical attack point) to replace this from the top? If so do I also need to take out the doggie bone in the front and try to ratchet it forward. (I have been leary of this, considering aluminium doesn't have near the strength steel does). If so will the only parts I need is the wire (already have in the box) and a gasket for intake? Thanks! Quote Link to comment Share on other sites More sharing options...
jman093 Posted May 7, 2013 Report Share Posted May 7, 2013 Since no one else has replied I tell you the little I know. I'm not sure where any intermediate connector is located for the crank sensor, so I don't know if the UIM needs removed, but if it does that would be the most that needs removed. You may need some o-rings for the coolant pipes, but that's no big deal. I also wouldn't worry about the dogbone breaking if you move it to the forward position. It was meant to do that. We've all done it lots of times, and I don't think one has every broken. Quote Link to comment Share on other sites More sharing options...
Scott205 Posted May 8, 2013 Author Report Share Posted May 8, 2013 I don't think there is an intermediate connector. There is a metal clip that holds the wire by the crank sensor (attached to the oil pan screw). Not sure what is on the back of the engine. The replacement wire is a singular piece. ICM on the 96-97 is up top, concerned it may have been left to touch the exhaust manifold or something sharp that causes it to short. IT gave me a lot of grief, then I pulled up on it as much as possible and it ran perfectly fine for 4 or 5 months. Just need to get it replaced so it is back to being old reliable.
