Sounds like a Coolent Temperature sensor. It will have 2 wires going to it just behind the breather by the thermostat, Or on your head in some cases.

This will be fault code 14 or 15. Sometimes bad sensors do not give fault codes and is overlooked. Report back.

I changed the fuel pump but the van still won't


And you know the fuel filter is good? Could be injector problem: just as a check, spray some starting fluid into the intake and see if engine runs a few seconds. If it does, it is a fuel problem. Check injector fuse, as a start. Check fuel pressure. Check injector circuit. If engine won't start with starting fluid, check if you are getting spark. Problem may be in the ignition system.

Van want stay started and will only start when you add gas to the intake astro van


This engine has an electric fuel pump, this pump is most likely defective. To replace the pump you must remove the gas tank, the pump is inside the gas tank.

1993 Chevy Astro Mini Van not starting


if your mini van has a 4.3 litre engine v6, when you turn the key on you should be able to hear the electric fuel pump start. the fuel pump is inside the gas tank,if you hear the pump you might want to change the fuel filter. The thing about computerized engines and a throttlebody is that you need a fully charged battery to start work with.
