Question about Chevrolet G20

1 Answer

I have a 1999 chevy van with a 5.7. the van has been sitting for 2 years. I recently started working on it, I had the van running for about 1 hour and it just shut its self off.(like someone turned the key off). Then when tryin to start it would just turn over. I replaced the computor, then it would start and shut right off.If you tryed to give it gas it will pop thru intake. I wrote you guys earlier and you suggested replacing the fuel filter and check fuel psi. I replaced filter and I have 80 psi of fuel pressure. and it still does the samething, runs for 1 to 2 sec and shuts right off??? any other suggestions

1999 Chevy Astro van will not start after sitting day of rain


Have the resistance checked on your ignition wires! When it's wet, the wires break down or don't allow enough voltage to get through to the plugs. Therefore the spark is weak & the van won't start. You may have to change them. Good luck!

1999 Chevy Astro Van. Don't know exact model # of


You should have a 4l60E in your astro van. Which is electrically controlled, so no vacuum modulator. However, to address the ventilation selector not working... look for a vacuum line exiting the firewall and going to the passenger rear of the intake manifold. You will likely find it broken or disconnected there.
