It could possibly be defection ignition coil or ignition wires arching when the weather is damp outside. Remove the doghose and while the engine is running, spray the ignition wires and coils and see if you can hear or see the arching wires.

1999 Chevy astro van won't start


Had the same issue with our 1999 chevy astro van, would crank but would not start. It had been raining and windshield had a leak, after 2 days of no rain it started. Pulled codes and was the Security system in the ignition switch. Hope this helps.

Will not start after raining.Takes two to three days of no rain to start again.Then van will run again till it rains again.


you don`t say but it sounds like the moisture from the rain is sitting on the plug wires causing them to short the voltage to ground and possibly moisture in the distributor cap.how long has it been since a tune-up was done to the van.

We ran ut of gas, then it ran for a couple days ut then it started to rain and rained for 3-4 days straight. my van wouldn't start.


If it is a minivan there is a connector under the floor on the drivers side behind drivers seat under van.(by front of sliding door) Could have water in it. Or your fuel pump could have gone bad.
If you have a rubber mallet I would try tapping on the middle of the fuel tank while someone is trying
to start it. Do you hear the fuel pump run for 3 second when the key is first turned on? If not hit the tank with the mallet. What van model and year and what engine is it?

Engine cuts out during heavy rains. This started


I HAD THE SAME PROBLEM BUT WITH AN ASTRO VAN. THE PROBLEM WAS WATER WAS GETTING INTO THE FUEL PUMP CONNECTOR UNDERNEATH THE VAN, NEXT TO THE FUEL TANK.THIS WAS CAUSING A SHORT, NOT BAD ENOUGH TO BLOW THE FUSE, BUT ENOUGH TO CAUSE THE PUMP TO SHUT DOWN. BEST WAY TO DUPLICATE THE PROBLEM IS TO FIND THE CONNECTOR AND SPRAY IT WITH WATER WHILE THE VAN IS RUNNING. ALSO DO A WIGGLE TEST, THIS IS DONE BY GRABBING THE HARNESS TO THE PUMP AND MOVING IT AROUND, IF YOU HAVE A LOOSE CONNECTOR OR A BAD WIRE THE VAN SHOULD SHUT OFF.

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!
