The top here is an update to my issue.

I will mention that the car has had a tune up of spark plugs, 02 sensor, cap, rotor, pick-up coil, and fule filter in the past month.

Here is what I have checked/done so far:

swapped ingition module
had 2 ignition modules bench tested at parts store
tested pickup coil according to factory service manual
checked the computer for codes (only go the standard code 12)
swapped the coil
disconnected Holley ignition box
verified that there is spark at the sparkplugs
verified the distributer turns
verified the rockers move
checked both injector fuses
checked the fuel pressure (44 psi)
removed the cat


The engine cranks freely and acts like it wants to start and did start for about one second last night but promptly died. The only other thing that I can think is to verify the timing but that is just a guess since the car does not run. Is it possible to static time the car?

I am open to ideas and suggestions

Hank

This is my unedited post from last night

The car 87 GT auto 166,xxx mi; Holley ignition box

I left work and noticed the car didn't have it's normal power. I didn't think much because I needed to get on my way. After about 10 miles while going up a hill I lost almost all power, I wasn't sure at this point if it was a tranny or engine problem. I shifted the car into neutral and tried to rev the engine, it stayed where it was about 1700 rmp with no power then died.
The car will not restart, so I am sure it is an engine problem.

Along the road I tried uplug my ignition box with no results. Next step was to check the computer for codes all I got was the gool ol code 12. Then I tried swapping the coil with no results. Finally I tried swapping the ignition module with a used one...it started for a second but then died as it had sounded before. I did note the exhaust smelled like fuel--possibly since I was cranking it so much with out running. I did note the distributer was turning. I checked for spark by grounding a plug wire and it did spark, how strong I am not sure.
At this point the tow truck arrived so I stopped trying to fix it along the road.

When I got back to my garage I tested the pickup coil according the the factory service manual, between the distributer bas and the coil connectors the resistance was infinate, between the two connections on the coil I read 825 ohms (FSM said between 500 and 1500 ohms). The pickup coil is less than a moonth old, a Delco replacement.

Any help is appreciated. I will try a new ignition modlule later tonght.

Please help.

oh yeah no top of all this fun I have to do all the wrenching anf typing with one hand now becude I missed my doctors appointment

what kind of ignition module do you have? if not a GM, get one.

How was your oil pressure while any/all of this was happening? any odd sounds? does it crank over just fine with the starter, or does it drag? the previous question about fuel is good, also possibly a clogged fuel filter.

I would try squirting gas into the throttle body and give it a crank to see if it fires up. If it does my quess would be fuel pump (not a job I would want to do one handed )

Also......
The thing I noticed in your post was after you swapped out modules you said it started for a sec then died again! This would also have me thinking about a control module!

I had a module go out once (it completely died). Well the replacement (albeit a cheap Well's) seemed fine for about 15miles and then the car started losing power and even shut off like 5 times in a mile worth of driving (it would shut off and not refire for about 10minutes....after waiting 10min it would fire and I could drive it for like 1minute and the cycle would repeat).
I Took the module back to AZ (auto zone) to get another one under warranty. They tested the one I brought in and it passed so they wouldn't replace it under warranty. After arguing with the counter guy for about 5 minutes I ended up buying a new module (because I knew that was the problem reguardless of what there stupid little tester said). Well this was a year ago and has run fine ever since! So with this said I would not count out a weak module!

Good luck!


Ohh yeah...forgot to ask......
Can you hear the fuel pump cycle when you hit the key?????

After reading the FSM I think the next step is to check for injector pulses. Does this seem like a logical step to you?
