Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.

These sometimes have problems with the magnet on the distributor shaft loosing magnetism. This causes the pickup coil not to be able to produce a strong enough signal for the ignition module and the engine dies because of no spark.

SOURCE: I have a 1988 Chevy K2500, V8-350 cu. in with TBI.

Oil pressure switch puts power to the pump after it is started.

Pumps also tend to loose their ground with age. I often splice in a new ground at the pump to eliminate that problem area.

Need some votes, thanks
