#1647 of 1973 1997 CHEVROLET ASTRO
Oct 07, 2007 (12:19 pm)
I have a 1997 ASTRO that keeps burning up fuel pumps and wondered if anyone had a similar problem with theirs. I know it has something to do with the tank ventilation,because you you don't keep fuel cap loose it won't run.I figure it something to do with the emission control system but not sure and wondered if anyone has encounted this same problem.Usually these vans have the same little idiosencrities.Any help would be appreciated.

I had a bump noise also; my problem was a loose shock mount. The bolt was loose and when I hit a bump the shock would bang against the frame. As for the beefing up of the suspension, I had the springs re-tensioned and a leaf added. Hope this helps.
#1649 of 1973 Starting Problems when cold
Oct 09, 2007 (6:00 pm)
My 97 Astro has a starting problem. I replaced the plugs, cables, rotor, and cap. New battery also. The fuel pumps seams to work fine; it hums on startup for a few seconds and then stops. It sounds the same as it did for the last 10 years. When I step on the gas it does NOT hesitate. It runs smooth, fast and idles fine. After it has been running it starts fine until I leave it sitting for few hours then problem starts again. Tonight I changed the fuel filter, will test it in the AM. My last resort is the fuel pump, but everything points to the fact the pump is fine. Could it be the ignition coil, when it gets cold and damp?

My previous 1995 Safari van had simular "start / no-start" problems. When warm or hot, it would run great. Had the odd "burp and miss-fire" but overall, it ran great. In damp or extreme cold weather, it sometimes didn't start at all. Her starter would crank and crank but she would NOT fire up. I would place an electric heater under its hood, plug in its block heater and a few hours later, she would fire right up. Almost like water in the gas and it was freezing within its CARB or fuel delivery sytem. Very strange...
My local mechanic waited until dark time, started its engine, let idle and sprayed the inside of its engine with a garden hose. Nice fine spray from bottom of engine and worked his way upwards. When he water sprayed its spark plug wiring, she "lit up" like a Christmas tree. Unseen by one's eye, my van had a bad batch of spark plug wires. Little micro-cracks and under the right cold / damp weather conditions, it would not carry the needed electricity. Spark energy to its attached spark plug.
Perhaps doing the same "spray your engine with water at dark time" might determine if spark plug or some other wiring problem as well. Worked for my previous van.
Hope this helps...

I had lots of similar problems. Replaced fuel pump, plugs, wires etc. Went through several starter coils until I finially replaced with a high performance coil and have not had the problem for two years now.
The astro has a problem with the original coil where it arcs to the oil dip stick tube and causes all sort of electrical problems. The high performance coil is seal better and uses high temperature plastic for the shielding so it does not where out.

I seem to be having a problem with ventilation in the tank.I think it is creating so much vacuum from someting not opening in the vent lines until it burns up the pump.I have to leave the fuel cap off to get it to run,it has to be something in the emission control not opening a vent line properly I think.I just can't figure where to start looking for the right valve or switch that controls it.This makes about six fuel pumps in two years so something can't be working right.Any ideas!
#1653 of 1973 Back door won't unlock
Oct 12, 2007 (2:42 pm)
New to the forum. Just bought a '92 Safari and can't unlock the rear door. The mechanism itself inside the door seems to work fine but when I insert the key it won't turn at all. Now, the rod that you pull on to manually lock/unlock the door has been replaced with a coat hanger so at some point it stopped working for somebody and they rigged up this replacement. Still, it doesn't look like the lock itself has been changed. I was wondering if there are any Safari owners out there that have had the lock seize up or break on them. If I have to replace the lock what is the best solution?

I have all kinds of trouble with the side door on my 94 Astro but never had and with the back besides sticking and wd 40 usally breaks it right loose. The contacts for the side door electric locks get corroded all the time and have to be cleaned or they don't work at all.Stick the small tube that attaches to the can inside the lock and it will probally break it loose;you might have to let it soak overnight if it's gotten a lot of moisture to it.

It could be the pump relay on the fire wall above the blower motor,their pretty cheap about ten bucks.I believe a fuel pump for that 97 van runs 300.00 to 350.00 dollars so I would try the relay first;and that's installing it your self.
