    Thanks Sandy162. I was leaning toward the fuel pump too. It hasn't happened since, but I haven't gotten into the same extreme heat situation since either.
    I do have an issue with the fuel pump that when I have around a 1/4 tank and I make a hard 360 degree turn to the right up hill it will starve for fuel. I have found that there was a recall on the fuel pump a year or two after the car came out but this one never got replaced. It is on my to do list. Just haven't taken the time to drop the tank yet.

Have you checked fuel pressure? How about spark on all 6 cylinders? Maybe a coil?

Trans shifts very hard after 5 minutes of stop and go traffic


A reason for hard shifting could be a problem with many things with various degrees of seriousness. It could be your ATF( automatic transmission fluid) is low or broken down and old. This would cause the hardness and the reason for stop and go traffic effecting it. Another possibility is your transmission is just shot, and the timing gears inside are worn and not properly shifting at the correct RPM causing a **** during shifting.

Some possibilties, not all!

Buick lesabre nightmare


Need to get a scan tool and look at the data stream while it is running for alot more info.Also any trouble codes.Sounds like initially,the engine isn't getting any fuel.I would have a pressure gauge connected to the fuel rail on the engine,so i could monitor the fuel pressure while all this is going on.Items to look at on the data stream would be timing,what timing is the PCM commanding for the engine.Also,have you checked for continuos power feed to the coils during this no start condition,and fire at the plugs while cranking.You could possibly still have spark,but maybe it is extremely weak?I have seen bad ignition switches cause weird problems before too.Many things power up through the ignition switch,just a thought.Have also seen bad PCM's cause strange problems..38 volts is a little on the low side for GM.Usually see those at,at least .50 and up,and rise steadily while pressing the throttle,up to just under 5.0 volts.Potentiometer with 5 volt supply.Vacuum leak can be checked with engine running at a steady idle speed,spray brake cleaner all around the intake manifold and listen for engine speed change.
