Question about 2002 Chevrolet Astro

1 Answer

2002 Astro van. Will not start. Getting fuel, distributor changed. Had a little accident while removing the thermostat housing. A ground snapped. Two wires. Black/white and Tan/white. I know the tan/white is a ground for the ecu. But I do not know what the black and white ground is from. Also when attempting to crank. Pressure is building and shooting through the thermostat housing. Bubbles form or a spray of fluid. No idea what the black/white ground that was attached to the thermostat housing does or where it comes from. Please help. Also what gauge wiring is good for the repair?

    I know that the ground is important. But the wire my have a short due to stress on the wire. I want to use a 14 guage to reroute the wire back from it's source.

Its a temperature sensor thats connected to a pop off valve its usually in the main wiring harness 16 to 14 guage wire should be sufficient for the repair and make sure u have splice connectors black tape corrodes quickly and could lead to other costly repairs the starting problem sounds like a crank position sensor located on the bottom of the motor

Yes, try ether. If still no combustion, consider timing chain/belt.

I would check the rotor very carefully. They tend to burn a hole through the plastic under the center tab. It's hard to see sometimes. The spark follows that path instead of to the wire terminals. You may just want to try a new distributor cap and rotor.

I need to know why my chevy astro.4.3l 2002 v6 after changing the timing chain wont run normaly.

Check the timing again to make sure you didn't slip a tooth when you lined up the marks. Make sure #1 is at TDC and the rotor in the distributor is pointing at the #1 plug on the cap.

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!

Dont know what the problem is

Check fuel pressure and check for spark and check that the airflow meter is operating, check for timing as well. Check for any wiring problems(loose connections, corrosion, condensation in distributor cap. Check distributor cap+rotor plug wire from coil to distributor. Check for any worn or damaged wiring or bad ground wire contacts. Air, Fuel, Spark and Timing are the key elements for an engine to run.

My 1995 Chevrolet Astro-van turns over but won't start

chk. fuse and relay for fuel punp. if that chks. out ok, then you will have to do a fuel pressure test. but after reading your problem, i'am almost positive its your fuel pump. make sure, do the fuel pressure test. all major auto parts stores carry the kit for pressure test, and they also will show you wear and how to hook it up, and what the pressure it should have. good luck.
