Since 1995, I have never had problem with this car I could not figure out, but suddenly it turns over, has fuel, but will not fire. Both the car alarm and clutch interrupt prevent cranking, so they are not suspect.

- I wired a satellite radio in, replaced a fog light bulb, and changed the oil the day before this problem occurred, but I have driven it several times (about 40 miles) since then with no problem.
- I checked all the fuses at driver's kick-panel and under the hood and the wiring harnesses around where I pulled wire. Everything else in the car seems to work fine.
- Battery is in good shape.
- The ignition coil does not test open at 400M ohm range nor indicate a short to ground from either of the low terminals or the high voltage terminal.
- I have voltage at both poles on the low side of the coil.
Do you

I am sorry, but I am just not seeing it, or what I think it would look like long view pix attached from battery to master cylinder.

I can see nothing electrical clear down to the bottom of the fender except the web of mounting brackets for vacuum stuff unless it is under the fuse block or battery ahead of the strut. I am still looking.

Thank you for hanging in on this.

Off to buy an analog meter, of course my two analog ones are not here and my Fluke is digital. My leads are all six in one row, so how do I know which is the self test?

Now that you explain it, it does show well, no, I did not.

A jumper wire from single connector to top right (signal return) and meter negative connected to bottom second from left (Self-Test Output). Positive of meter to positive battery terminal. Used 250 VDC scale because I was not sure what voltage was generated, but needle was rock solid.

I presumed the test involves inserting the meter to an active circuit. Is the battery still to be connected to the rest of the car when I try to read the codes?
