QuestionQUESTION: Think it must be different, I have a blue and white wire going to pin 3
Answer: Please check that again. If you have the 60-pin plug I show a red/white on pin 3 and a dark blue/white on pin 9.
If by chance you have 2 40-pin plugs (as shown in the '98 manual) then the red/white is on pin 46, and the dark blue/white is on pin 20.
In either case the red/white should show 12v all the time, and the dark blue/white whenever the ignition is in run or start position.
Hello again! I have a 60 pin connection, there is a white/red wire on pin 11 and pin 55 no power to pin 11, and 6 volts??? to pin 55.
Answer: Hi Ken,
I just can't find any 60-pin pcm plugs in that time frame that has white/red or red/white on 11 and 55. Only one such red/white wire on pin 3. 55 is shown as tan/red and is for the speed control relay; pin 11 is black/tan and a power ground wire, so 6V and no power to those pins seems ok. The color code don't agree with what you say you see.
Aha! I wonder if you are looking at the TCM instead of the PCM? The PCM is hidden under the air intake/filter box, while the TCM is out in the open on the driver side fender. The TCM shows a red/white on 11 and a tan/red on 56, but that is not the module we need to get the engine to start!

Yup, Im an idiot! There is two plugs, located red/white on one, power is good, other plug had blue/white power good...
ANSWER: Well then the check engine light should work, and if not then maybe it is burned out? We need it to find if there is an explanation for the no start.
To remove the cluster, remove the left end cap fromt he dash, remove headlamp bezel, headlamp switch, and move switch to allow cluster bezel to be removed. Then remove the top bezel from the center panel of the dash also to give access for cluster bezel removal. Then lower the steering column to lowest level, remove a couple of screw on under edge of cluster bezel, remove bezel, then remove screws from cluster lower edge and move it out (note latch on top edge). Then find check engine bulb and check it out.
But before doing that, fuse #17 in the fuse box behind the dash should be checked as it powers the check engine light as well as other things of the cluster.

QUESTION: seems like too much of a coincidence the check engine light worked thurs night when I drove it, then didnt work fri when it wouldnt start. Just for clarification, there is a blue with white stripe wire at the front of the rearmost plug, and a white with blue stripe towards the rear of the plug, which one is the relevent one?
AnswerThe blue/white that powers the pcm is on pin 20 of the black plug, which is the end of a row but I can't tell front or back. I don't notice a white/blue on the gray plug. I do see a wnite/dark green on pin 77, three from the end. Did you see my note about fuse 17? While you are at fuse #17, check to make sure it has 12V on it when in the 'run' position.
