1995 Chevrolet Astro - Page 5 - Answered Questions & Fixed issues

Check your fuel pressure at idle and under a load, if there is a fluxuation greater than 2lbs you should check for a bad fuel filter and then the pump return line.

what are you trying to do?

don't have a diagram but this van is notorius for the vacuum lines than run on top of the front of the engine(by alternator going over upper intake) cracking or breaking assuming you have a 4.3l. hope this helps.please rate helpful.

You have a bad heater core it is located in the passenger side dash module , and it will fog the windshield with a film of coolant

As the Astro is on a truck frame I would think it would be quite simple there should only be 4 to 6 bolts holding it on. You should be able to replace it your self.

sounds like you have either a bad head gasket or a cracked head

An easy driveway job. Disconnect battery, crawl under truck, disconnect wiring to starter, remove two bolts holding starter up 9/16, and remove.

Does the van have an alarm? If so it sounds like it is going into the start kill mode. Disable the alarm by looking for the brain which is probably under the dash and just unplug it.

check to see if the alt. is actually grounding to the engine and battery, run the vehicle and check voltage at battery, should be 14.5 volts or so if not run a ground from alternator to battery, then run a live

if it has rack & pinion steering the rack is bad

see if braek lighs work if so check fuse box for fuse or related fuse to that sys tem if its not that you need it ckeck the turn signal switch it self see its is getting power and you don;t have a bad ground to it then the switch is problely bad

I would check the air cleaner and replace it just to start...
What you are saying sounds like a faulty injector that is stuck open... But a plugged up air cleaner could do this too...

In your fuse box. May be under the hood or drivers side floor area.

Wow! This is a very detailed job. There is quite a bit to do. I would suggest going to the library and checking out the Chilton's manual. If you get instructions on here. Someone may leave out some steps. It is quite a job to change a CV joint. And sometimes takes an air hammer to get the ball joints off. And without the proper aligning tools you will need to have the vehicle aligned when you are done.

the fuse info is located in the owners manual, u can access this manual for free at the GM owners web site, u will nneed a Yahoo ID to use the site, that is free as well and the latest Acrobat 9 reader
here is the direct link to the site

while running, the alternator should be putting out 13.2 to 13.8 volts.

injector assembly under upper plenum is broken. r and r upper plenum and replace injector assembly.

Hi,

It would seem that you have checked/replaced most if not all of the usual suspects. Pls try:
1. start the engine on a dark night with the hood up. check for any arcing/high voltage spark from any of the high tension wires;
2. you may want to reconsider this step! run the engine, pull the spark plug wires (carefully, extremely high voltage) one at a time and note if the idle will not change. If no change that plug is not firing;
3. check the ignition B+12 going to the ignition coil primary terminal. If it is physically in contact with the A/C hose/line, it may be loosing a few strands inside the insulation, replace.

Other than the above, a few more checks (but not as simple):
a. check that the fuel pressure is between 50 to 66 psi;
b. replace your plugs to AC Delco CR43TSM or CR43TS or 41-803 Platinums.

This page may be of additional informative if not an interesting read. To my knowledge, a 1995 Astro van shares the same W engine with a GMC Safari and therefore would have the same concerns/solution.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Yes, when you buy the belt tell them you have no ac. (but do you really want no ac) Goo luck
