Check the coil wire and ignition coil in addition to the distributor cap and rotor.

This, Check for fire between the coil and dist cap. If you have fire there, Check for fire from dist to any of the spark plugs.

Did you ever figure out what was wrong with it?

Not yet guys. Will be early next week before we can take a look. I will need to tow it first.

When was the last time you replaced the fuel filter?

I thought it was starting but with difficulty. Now it won't start at all?

Crankshaft Position Sensor could be suspect. One quick and dirty way to test it is to crank the engine over and watch to see if the tachometer needle moves. At least on my 92 Bonneville(s) that was one way to check it. Another way to check it would be with a timing light. No flash, no crank signal. Could also be a defective ECM but usually those will throw a SES code. A failed crank sensor may not as when it goes open circuit the ECM may read that signal as the ignition being turned off at the switch, a normal condition obviously.

Crank sensor is at the bottom of the plastic timing cover, about the seven o'clock position.

Ok guys, I want to thank you all for your help here. Obviously you are very knowledgeable.

The fuel pressure was good. It was spark issue. And yes, E it would not start. As it turned out is was the Ignition module. Not a common problem. Mechanic said in 20 years he could not remember replacing one. Anyways, $300 and it runs again.

A guy I know wants to buy it. I had not planned to sell it. But he has made me a decent offer and I kind of feel I will be continually putting money into it. So I am going to part ways with it. Maybe upgrade to a used 3/4 to short box in the next few years. It has served me well for several years. In a way kind of hate to let it go. Like the manual tranny, windows, locks etc. But it is time on this one.

Again, thanks guys. I am so thankful for all the great advice you offer when asked. You are truly a blessing here.

Sincerely, orc

Thanks for posting the solution. And you're right, this module failing on that vehicle is very rare.
