Trouble starting 94 Tahoe LT
I've had two instances where it was difficult to start my blazer.
The first was after towing on a 90 degree day 150 miles at highway speeds. After I parked it and took the trailer off I got back in to start and it would fire. After several attempts the negative on the battery fell off. I put that back on and it fired up right away.
Fast forward two weeks to today and I couldn't get it started. It was around noon and another hot day. 24 hours before it was running fine in the heat. This time there was no battery cable problem. I tried again a little while ago since it is quite a bit cooler and it started right up. I drove it around to operating temperatures and it was fine to start again.
It seems like a vapor lock happening or is it a more serious problem?

pressure > 55lb, over 50 for ten minutes IIRC

The first instance it would crank but not fire until the cable fell off. Then I put the cable back on and it fired right away.

Well it happened again. Would not fire up. I tried for about 30 minutes and decided to put fuel down the intake and it started right up and drove 40 miles right to the mechanic with no problem. I don't have the time to work on it the next few weeks so I will let him deal with it. I'll let you know what he finds out when he digs into it tomorrow.
