Aftermarket fuel pump on a chevy silverado

SOURCE: 2000 chevy silverado 1500 4.3 eng

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.

When your vehicles stalls, check to see if you also loose other indicators as well. Check your indicator lamps. If you have lost all power, this may indicate you have loose or corroded connections from your battery. Im sure you checked your battery already. However, a common mistake people only check the voltage. You also need to check to ensure your battery has a proper/solid ground to chassis. Sometimes these come loose and/or corroded. Clean your battery terminals and battery cables really good. They all should be shiny. Tighten them firmly when you reinstall. Try and start again. Sound to easy, but it has solved many issues with the problem your having. Hope this helps.

do not think alarm would cause this do you have a check engine light on?? there is a coolant temp sensor that reports to pcm it could be out of range you need to hook vehicle to a scanner and check the temp that is being reported by coolant sensor when cold and when hot also may want to look at mass air flow sensor also have you even thought of ignition module what symptoms you have sounds just like an ignition module problem
