#46 of 115 Re: 1997 ASTRO FUEL PUMP PROBLEMS [dlm1954] by rabarrett Oct 25, 2007 (3:40 pm)
Replying to: dlm1954 (Oct 07, 2007 4:50 pm) dlm,   There are several possibilities causing these problems. There are all electrical in nature, so feel free to ask questions if unsure of something I have said. 1. Are you sure of the quality of the fuel pumps you are purchasing? 2. Are you using the cheapest fuel available where you drive? Do you keep the fuel tank at least 1/4 full? 3. It is possible for either fuel filter to restrict the delivered fuel, either starving the pump, and overheating it, or the pump could be trying to overcome a restriction, causing an increase in current draw. 4. Was thge fuel pump relay replaced at the time of the pump replacement, every time? A damaged pump can damage the relay, causing subsequent pump failures. ray
#47 of 115 1994 CHEV. ASTRO POWER PROBLEMS by dlm1954 Nov 04, 2007 (6:41 am)
My wife went to the store last night and when she started to leave the van didn't have any headlights or power to the ignition system.The van cranks fine but evedently isn't getting power to the ignition,because the headlights aren't working either.The dash lights and everything else work fine but the headlights and ignition aren't getting any power.The book says there is a 40 amp battery fuse under the hood but I have never seen it.Any help would be greatly appreciated,maybe someone out there has had the same problem before.                   dlm1 Replies to this message: 1998lincoln (Dec 06, 2009 8:58 pm)

Replying to: astroed (Dec 16, 2007 4:01 pm) I think you can get a loner tool at Auto Zone or Advance Auto but you'll have to remove engine cover and hook gauge to fuel line to see how much pressure you are getting to know for sure, and of course you can have someone turn the ignition on while you listen for the pump by sticking your head underneath the van by the fuel tank; if the pumps working you can hear it running. If you don't hear anything do a pressure test before replacing pump but it sounds like a pump.GOOD LUCK DLM54

#51 of 115 '99 Astro Windshield Washer Pump by mfrei Dec 22, 2007 (11:18 am)
My '99 Astro windshield wiper pump is not working. Took it out. Tested the connecter with a voltmeter. Get 3 volts when activated. Hooked up two 1.5 volts to the pump and it runs. But when I hook it all back up, nothing works.   The rear pump was working. Tested it the same. Read 6 volts at the leads. Now it doesn't work after putting it together.   I tried priming the lines.   I can't find any fuses that are bad.   What am I missing? Replies to this message: vanman18 (Jan 23, 2008 2:20 am)

#53 of 115 Re: 1995 GMC Safari Radio Clock [hy4woj] by vanman18 Jan 19, 2008 (8:10 am)
Replying to: hy4woj (Jan 20, 2007 1:17 pm) I have a 1996 AWD Safari. The battery in it started draining over night. I had the battery and the charging system checked. I inspected every part of the wiring harness I could see without tearing the van apart. I checked for shorts in the fuse box with my volt meter and found one somewhere in the interior lights. They all work, so I was stumped. So I installed a battery kill switch in the lower dash panel and haven't had any more trouble, except I have to reset my clock every time I drive it if I want it to read right. Also, I don't know if this will harm the computer after a while. I figure if I find the short later I can just leave the switch on.

Replying to: mfrei (Dec 22, 2007 11:18 am) Sounds like it could be bad grounds. I have had success with running a wire from something metal on whatever is malfunctioning to the nearest metal body part. The last such fix was a wiper motor. I clamped a wire with a bared end to it's body with a radiator hose clamp and crimped an eyelet onto the other end, which I put a screw through into an inner body panel where I could reach it easy. Crude but effective.

Replying to: waltone (Oct 15, 2007 7:50 am) Sometimes this can be fixed by adjusting the rod tht runs alongside the steering column from the dimmer switch to the turn signal lever.
