Screwed up???

[94grandprix]

Somebody soldered 2 yellow looking wires with a black strip together then onto one with a white with black strip going into the icm,you can't see much but here's a pic http://i1121.photobucket.com/albums/l519/Cody_Woodard/null_zps4b22f836.jpg them my icm harness baby blue wire with black wire had paper clip shoved up beside it http://i1121.photobucket.com/albums/l519/Cody_Woodard/null_zps1f314a1e.jpg

Ok will somebody go and take your icm plug off and see if your white wire with black stripe is going into 2 wires,I think somebody soldered them

Part 1 -GM 3.8L Ignition Module Test and Crank Sensor Test (3X, 18X)

Go there and it will show you how to test and where the wires are supposed to be.

 

[94grandprix]

Ok but I'm going to take my harness out first so I can look at it better

 

[94grandprix]

Bill help me lol,it seems to be 2 extra wires a black with white stripe and yellowish or white with black stripe,are there any other 3.8s that use a different harness that dosent use the same as the gtp

 

[REDCRAPGP]

Ill take a picture in the afternoon for you

 

[94grandprix]

Ok just to be 100% clear,my white with black stripe is going into 2 yellow with black stripes,it's hard to tell and then 1 with black stripe going into 2 blacks with white stripes,thanks and ill get a better pic of the wires tomorrow

 

[94grandprix]

Redcompg I don't think gm would so that would they?

 

[94grandprix]

Also from the top plug it's roughly 8 inches down to the solder point

 

[94grandprix]

Can somebody tell me how to get that harness off,I know there are a few grounds bolted on but what else do I need to get out

 

[Booba5185]

If I remember right, you unplug the ICM, unplug the crankshaft sensor, unplug the camshaft sensor, and unbolt the ground at the top of the ICM bracket (connected to the top bolt coming out of the head itself - facing the passenger side). After than, proceed to fillet your hand fishing the harness out, while trying to remember how is was ran so you can put it back...fillet your hand again.

 

[94grandprix]

Ok to be 100% sure the cam sensor is basically to the left of the crank pulley if you were looking at the pulley with the tire off,so only 1 ground?

 

[Booba5185]

Yep. the plug of the cam sensor faces down and to the back, so the wire is run behind the top of the HB (in a groove) and has enough slack to plug into the sensor. Take a wire brush to the grounding points as well, you want that to be a solid ground.

 

[94grandprix]

Thanks,you saved me some time,I'm going to take it off later and try to fix the wires the right way

 

[94grandprix]

Update:the wires came from factory that way,I found a wiring diagram but that dosent exsplain my rpm hand not reading,what's next???

 

[94grandprix]

Ok I got it ran right but not sure were this plug goes http://i1121.photobucket.com/albums/l519/Cody_Woodard/null_zps68cd627e.jpg the little green plug was unplugged and I think that one ^^^ was shoved in it but not sure,the little green one fit right in it,and the loose one will not,I thought one went to the crank which is 4 wired and the cam is 3 wired,were is the cam sensor then,please help

 

[94grandprix]

Got it

 

[94grandprix]

Is the cam sensor behind the water pump pulley?

 

[REDCRAPGP]

Do you mean the CPS if so that's behind the harmonic balancer near the ac compressor.

 

[94grandprix]

I know where that is but we found the cam sensor,it's never been plugged up I guess or the oil sensor,idk how it was running,maybe my rpm will work now since it seems to be hooked up right
