97 chevy blazer w/ 4.3 won't start unless i pour full directly into it....what is causing this. was driving and it just stalled ...fires but won't turn over completely

sounds like ur fuel pump is burned out (broken impellor) get a new one.
of course she revs and dies if u pour fuel down the carby...duh.

Bad fuel pump, fuel filter, it may not have enough pressure or you aren't getting spark

Camshaft position sensor. It needs to know which cylinder is needing fuel, so it can fire the injectors at the correct time. It must have failed you. It should not be too difficult to replace or very expensive.

Anti-theft system ,replaced computer . needs programming ! Dealer .

CHECK ELECTRIC MOTOR ON THE FRONT DIFF.

you have an electrical problem . check fuel circuit fuses, relays and sensors

#4 is compressor clutch relay...

You should also check LOW and High pressure switch(s)...

Try giving it a shot of starting fluid. You don't say if it's actually firing. If it tries or runs for a few seconds off of the starting fluid then try changing the fuel pump relay. It's inside of the glove box on the left hand side behind the little door. If that doesn't work it's most likely the fuel pump.

Firing order is 1-6-5-4-3-2. Distributor cap should be numbered. Number one cylinder is front on driver's side (3 and 5 follow on same side). Number 2 is front on passenger's side (followed by 4 and 6).

You need to check the fuel press, the test port in on the rail, also run a code test on the ECM/PCM, this checks for trouble codes and also lets you know the computer is working if it tests ok.
