1995 Chevrolet Astro Van
Reader Question: I have a 1995 Chevrolet Astro Van All Wheel Drive V6. For over a year now as I am driving the engine would quit, while pulling over to the side of the road, I would try to restart and it would always restart but now when the engine quits it will not restart for two hours later.
This could happen after driving only ten minutes to one hour. I have had three different mechanics look at it. They cannot find the problem. The fuel pump has been replaced three times, fuel filter replaced, much of the wiring has been repaired or replaced, battery was replaced, starter and alternator replaced.
I feel that the mechanics are guessing as to what is wrong. I have spent so much in repairs and the problem still has not been fixed. The van is still in great condition with low miles to just junk but that is what I am about to do if it cannot be repaired.
Please help, I am very discouraged. I feel it is in the electrical system.
Thanks for your help.

Hey Robert,
I feel your pain man. Intermittent dying problems can be a real pain to diagnose and repair. You really need to narrow down this issue to a lack of fuel or lack of spark problem though. Next time this happens I would listen for the fuel pump “whine” for 2 seconds when you turn the ignition key to the ON position.
If you do not hear that electric fuel pump whine from the fuel tank you might have a bad pump or no power going to the pump. Sometimes you can get someone to bang on the bottom of the fuel tank with your fist or a rubber hammer AS you crank the engine over.
This can jump-start a weak fuel pump. Fuel pumps can overheat and fail to operate again until they cool down. Three fuel pumps replaced in a few years would make me suspect installation of cheap brand fuel pumps, too much battery voltage to the pump for some reason or a problem with the installation of the fuel pump inside the fuel tank that is damaging the fuel pump.
If you hear the whine, I would then check for spark at the spark plugs. If no spark, check the ignition coil, distributor cap, and ignition rotor and ignition module and pick up coil inside the distributor. An ignition module can overheat and fail to produce spark until it cools down again.
Blessings,

I have a 95 Astro Van it turns over but won’t start I had been having problems starting it for awhile now but now it won’t start at all I can hear the fuel pump go on so I don’t think its that. It sounds like it wants to start but it just won’t almost like its not getting gas can anyone maybe help figure this out
These vehicles are suspect to fuel pump failure, even though you can hear the pump does not mean its pumping enough fuel to start the engine. Sometimes banging on the bottom of the fuel tank with your fist or small block of wood AS someone cranks the engine over will kick start a weak fuel pump. Besides having fuel pressure and volume at the engine you also need spark and compression. Each spark plug should have spark going to it, I would first start by checking the inside of the distributor cap, ignition coil and spark plug wires. If you have spark and fuel pressure, then check for proper compression at each cylinder using a compression gauge. You could have a blown headgasket or the timing chain could have broken or jumped……BUT you should hear a difference in the sound of the engine as it spins over if that was the case, it will spin over much easier than before if there is no compression.
I have an 89 chevy astro van. I took the gas tank off to put a new fuel pump in. The bolts on the straps holding the tank in place is what I am having a problem with. I started taking the bolts off the straps on the drivers side first. They would not come completely out of the chassis. So, I went to the passnger side and those two bolts came all the way out and went back in with ease. However, the two on the drivers side now will not tighten or come out (they just hang there loose). The chassis is tube like and so you can’t see what’s going on inside there where the bolt is going into. If no one has an answer, I am going to cut 1 1/2 inch holes in the side of the chassis so I can see what’s up inside there. Teddy
There should be a nut either welded into the frame or attached to the frame that I can recall. I would suspect the nut is just spinning around on the end of the bolt. Maybe you could get a screw driver in there to hold the nut in place long enough to get it to grip on the frame?
1995 astro van 4.3 will only start with starter fluid. Once started runs like a top. Fuel works, sending unit works, can’t figure it out?
More than likely a weak fuel pump, bad fuel pressure regulator or leaking injector. Have the fuel pressure tested at the engine with a manual fuel pressure gauge. Also try banging on the bottom of the fuel tank with a block of wood or rubber hammer AS someone cranks engine over. If it starts you have a weak fuel pump.
All you people with problems stalling after 2 or so minutes ,well you are in luck because I have the answers. It will all be free If you call me between 11 am and 6 pm any day. OK. I too had that problems and I repaired them all in one day.
I had replaced 3 fuel pumps on my 1994 astro van. I had the fuel sending unit replaced a while back and so far no more problems.I am fortunate my brother-in-law works on autos. He was the one that told me to it was the fuel sending unit. I took it to him after having the fuel pump replaced 3 times in three years by an auto repair shop at around $450 to $500 dollars each time to replace the fuel pumps. I was also told by an towe truck driver that he got a lot of calls about the chevy asto and safari vans because the fuel pumps always seems to go out.
95astro shutoff while i was driving it i tryed cranking it backup and didnt have no spark
have the injectors checked
