1996 Chevrolet Astro Logo
Posted on Nov 18, 2008

I have a 1996 Chevy astro Van I have problems starting.

If I turn on the key and let the fuel pump and everything stop running then start it, it will start perfectly for that day. If not I have blown three mufflers off of it from the backfires and it will not start that day. We have replaced the fuel pump four times now.
Help........ Please

    I am Having the same problem, only some days I cant seem to get it started at all! Been a Project for a few months now, replaced coil,cap & Rotor, Ignition Module, Coolant Temp, EGR, Fuel pump/filter, Many Hours spent checking wires/grounds etc, & swapped out the computer for a known good one! HELP, I am on my 6th new muffler & just blew it out,....some days it will start like a new one,...other days it floods immediately! Had it to the dealer twice & nothing, all it seems to do is throw a new code every time it does this. TIRED of the Chasing/Replacing parts game for nothing! Been throwing out money for nothing!

Jiggdout69 is absolutely right. Change your Manifold Absolute Pressure sensor and problem solved.

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.

96 Astro Fuel Pump Question?? no start/Flooding

With the upper plenum removed and spark disabled turn on the key and allow the fuel pump to prime while watching the fuel lines from the back of the intake to the injector. I suspect you lines are leaking. Have seen this before. ALOT.
