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.

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.

Got it, got it out and had it tested x 2 -- it is green lights all the way. Can I test the six leads to it to some value?

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?

If I did it right DC Voltage range, key in ON position but not cranking, nothing but straight 12vDC measured.

It does not show well in diagram but did you run jumper wire from top row far right term to the single wire?

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?

NOTE: I had battery disconnected for a bit yesterday and have pulled and reseated every fuse in the vehicle.

Jumper as you note STI to upper right (as I am looking in the end) of the connector.

Turn key to on and check engine light flashes what seems to be 3-3---1--3-3. Dash represents relative length of the pause between numbers.

It is hard to tell if there is a first single flash because all the lights come on and off in the self-test, so it may be starting with a 1-. I cannot tell.

Did this three times with the same result.

Unfortunatly 33 or 133 are not vialbe codes. So lets go back to basics at coil check Black/Pink wire for 12v= with key on. Also put test light on Yellow/Blue crank flash or steady?

OK, raining not, will try once it dries out :)

BTW I just duplicated those codes, they may not be documented, but they are certainly "real."

Weather and time not conducive to pursuit of the problem -- I have to work outside. Will check back in when I can pursue.

I do live in Fla -- but it has been rain and chilly (mid-30 degree nights) on my days off.

I found the no-spark problem, seems to have been a bad connection at the Powertrain Control Module. I apparently goofed something up when I was pulling and pushing wires. After I found that, had another problem show up regarding timing that I fixed in an odd way, but car is tuned up running like a champ now. Thank you for your help and the information!
