I just spent the last 30 min. studying the wiring diagrams in my haynes manual. Truly I appreciate it!

To test the diodes... I had some trouble testing them, but the in car one is OK. My meter flashes a number one way and 0 the other. The underhood one I couldn't get any reading on. Replacement on the way.

how to find them.

Check Fuses 1 and 10, both are in the auxilary fuse box under the hood. Both OK.

Check the starter relay diode in the fuse box under the hood. Its located right under a line of 4 fuses. Replacement on the way.

Check fuse 30 in the fuse box inside the car. OK

Check the ignition relay diode in the fuse box in the car. Its on the bottom between the alligator thing and the rows of fuses. Seems OK.

Also, if you said there was a smell, then look for wires that look different with dark spots on them or spots with the insulation bubbled up or even missing. Nothing obvious. I got under and looked up as well.

Check the small wire at the starter for resistance. Here's how to do it. The resistance should be very low. Under 1.

While you have R6 removed use your voltage meter to check for voltage in the socket that pin 3 of R6 fits into. There should be battery voltage there all the time. 12.8.

you can do this. Disconnect the battery. Leave the small wire on the starter disconnected, leave R6 out. Take a short peice of wire and short out the sockets in the fuse box that pins 5 and 3 of R6 fit into. This will make the connection that R6 makes to send power to the starter. Take your resisitance meter and put one end on the potitive battery cable terminal and put the other end of the meter onto the end of the small wire that attaches to the starter. The resistance should be low. Under 1.





I also tested the starter by taking a large piece of wire (piece of old jumper cable) and connected the small wire to the large wire on the starter and it cranked!! But no start. I juggled everything and made that connection, opened the throttle AND PRAYED all at once. But still NO GO!

I'll try the DANGEROUS way tonight.

What else should I be checking? I pulled the back seat and foudn the fuel pump and checked the wiring on it. Seemed fine.

I opened up around the steering column and found the PATS ring that goes around the ignition/ key and checked the connections there, seemed fine. Nothing else seemed strange there. All wiring looked fine...

Strange question. I have taken my console out recently. What is the blue box basically behind the little pocket on the console, below the head unit? Just curious. Behind the console I found a wire with a flat connector about 2 inches long by about a 1/4 inch that was not connected to anything. The wires come out from the same spot in the dash as the lighter power.

Any other ideas? A new diode and neutral safety switch will be here soon, probably tomorrow (I hope).

Does anyone know where the PCM is? PATS? Ignition switch? Any photos?

Thanks again for all the suggestions and help. I do appreciate it!
