#1 of 219 GMC Safari & Chevy Astro - Fuel Issues
Nov 02, 2006 (2:48 pm)
I have a 1998 Chevy Astro, 156,000m this is a recent issue where if it rains heavily during the night my van will not start at all the next morning, I dont seem to be able to hear the fuel pump engaging Key on position, I have checked and replaced the fuel pump relay, but still the same problem persists. I am not sure what the culprit could be as the only time i have trouble is when it is very wet out, this has happenned once before after getting to work and trying to leave to go to a jobsite.

#5 of 219 GMC Safari fuel pump

Ok, people. I am new this. I am in dire need and I need help. I need a fuel pump for my 1998 GMC SAFARI. Problem is...they are prohibitively expensive and I am a poor parent of 3 children with 1 in college. Anyone has any idea on how to fix/replace the fuel pump in a fashion affordable to me? Thanx so much. Bye.
#6 of 219 93 Chevy Astro won't start?
Dec 06, 2006 (12:48 am)
My 93 Astro 4.3L quit running one day and won't restart. It has 60 psi of fuel pressure and plenty of spark. It also shows a code 43 which is the electronic spark control system faulty. Replaced the ignition module to no aveil. Anybody have the same problem?

#10 of 219 no start problems continue...

SO this test is to place a piece of wire or metal(something that will stay in place on it on...like an alligator clip and then hold the boot with a well insulated screwdriver (as in drapped over it ) and gradually move the tip away from the grounded metal surface.(Would insulated pliers help me hold/control it better?---If this is not a good result should I look at new wires or plugs(different brand or premium platinum) that give a better spark or what would help this? Or is there another part which provides this spark. I replaced the ignition coil already.
If the fuel presssure leaks down before a couple of minutes does that mean the injectors are not providing enough fuel long enough? Could their signal be dropping out too soon or are they bad. Could this be the fuel pump. I heard from another mechanic that this system had lots of problems and has been updated. He was lobbying for work but did say as you that if I am going to do the work myself that to make sure I check everything out before I invest in the updated injectors system. Last time I checked it was about $520.00 and I think its a dealer only item. This current system is CMFI on the 1995 I have. In 1996 they went to CSFI and if it retrofits (and this is the solution maybe I could find a slavage one . The bad news would be if they just changedthe CMFI and only new will work.
On the Explorer I was checking the IAC valve. Since I cleaned it out(carbon buildup) the idle is doing as you describe. It does go to about 1100 before settling down to about 600rpm. It actually was racing up before. I will continue to observe this and if it continues or reoccurs I will clean it again. It may need to be replaced. The TPS (throttle position sensor also had inconsistent voltage but with this improvement it may have nothing to do with the surging/racing idle at this point.
