No Start Situation

Well....made it thru the hurricane with no issues other than too much yard cleanup and assisting the neighbors. I did the ALDL test and it only showed 12. No other codes. I am going to rent a fuel pressure tester next and see what happens. I did pour fuel into the TBI to see if it would fire. It did not. I had pulled the computer out to have it tested and the only place that I knew of doesn't test computers that old. This prior to doing the ALDL test. Would that have cleared any other codes?

Yes; if battery voltage is unavailable to the ECM (for 30 seconds or more), all stored codes will be cleared.

2X gpmorgan: If the engine did not even attempt to fire with gas dumped down the throat, that would pretty much eliminate a fuel supply problem.

Try pulling the 4 wire plug from the distributor and check for a spark while cranking.

Finally have time to work on the R10. Found the coil was bad. I have installed the new coil and the truck is running fine. Thanks to all that replied and gave advice. With the coil bad why would there be spark at a plug? Could it be that the spark was not hot enough?
Very puzzling. Thanks again.

it could be that it was weak or the coil was taking to much time to be able to reproduce the spark for the next cylinder.
