    I changed the crankshaft sensor and this corrected the problem, Chevy repair manual states the crankshaft sensor if bad will show one or two OBDII PO codes. No SES codes were listed, go figure!

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.

The backfire could be a problem with the distributor cap or plug wires, or lack of fuel. The cap or wires could get damp and short out until the engine gets hot.
The fuel pressure could be low or not steady until the engine warms up.

92 grand caravan starts poorly, then runs ok when warmed up, then poorly after 30 min. to 1 hr. of driving. Then stalls and won't start till 30 min. or so later.

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

1985 toyota 4runner running too lean

Maybe it's not running lean. Maybe it's misfiring. Since you put in new fuel parts and that didn't help, maybe there is an ignition component that fails when it gets hot. A bad coil can do this, also the igniter-rarely, admittedly, but you could have it tested. When it stalls and won't start, if you check for spark and find none, it would confirm an ignition problem.
I hope you find it. Post back and let us know.

1991 camaro rs v6 runs good tell it gets hot

You'll need to figure out if it is fuel or ignition related.
Some common things to check are trouble codes in the computer, fuel pump pressure, and sensor readings.

Have a '94 S-10 Blazer Tahoe 4X4 and it starts

My suspicion is a starter going bad. Sometimes when starters get old and worn they will start good when the engine is cold but not when the engine is warmed up. Did you perhaps notice that lately is seemed to drag when you tried starting, especially warm or it seemed to crank a little slower? I'd replace the starter. Hope this helps.

Car runs 6 minutes then stops. Fuel pressure good.

well since you already swapped the ecu that should rule out the question I would say sensor problem.
