#105 of 154 Re: 2003 Astro, Missfire problem [waterski1] by kerijo May 20, 2008 (3:48 pm)
Replying to: waterski1 (May 20, 2008 3:36 pm) Nope, no machine gun noises. Just a simple clunk or 2 coming from the right front as I make a left turn. I can turn right all I want...guess I'll just drive in circles!! And no, mine isn't AWD. It used to only clunk once in a while, now it's with every left turn.   Now, let's all pray that there are no fuel pump issues, please! I have no time for that!!!!   Fingers crossed.. Keri

Replying to: jorja (Apr 07, 2008 4:45 am) I am thinking you might have a bad ground. Electronics (like your fuel gauge) can be funny like that when they have bad or inconsistent grounding and the silly things like surging, and sputtering can be a sign of a bad ground circuit as well. Luckily the electrical grounds are tied and you should be able to find the strap in the engine compartment behind the EGR valve.   Hope this helps

Replying to: pwr2020 (Mar 11, 2008 1:58 pm) Exactly where is the fuel pressure regulator located ( and the pulsator valve )? Is there any way to check them? I see a few items that may be one or the other, I just don't feel its necessary to tear into something thats not connected to the problem. Thanks for your help!
#108 of 154 95 Chevy Astro Van Loses gumption when accelarating by badasscowgirl Aug 18, 2008 (2:13 pm)
My van runs good and starts like a new one. But when i go to step on the gas it stalls back like its so hungry it hasnt had gas in three months. I just got it and have already put almost 400 into it just to get it to pass smog. Not looking for a cheap fix want a perm one. Please help. hoping i need to replace fuel filter has new pump. new cap rotor and wires new cat converter, new air intake sensor and new wires. as you can guess mech told me egr needs replacing and quoted me 400 more to fix it. maybe one of you had same problem and was fixed and silly enough easy as pie to do yourself.

Replying to: badasscowgirl (Aug 18, 2008 2:13 pm) I had a similar problem. Turns out it wasn't a bad fuel pump but rather a fuel pump that was not properly installed. The bracket holding these fuel pumps ( and the rubber insert) are extremely flexible and can be bent into a position that does not allow the proper amount of fuel to flow thus causing the engine to starve for fuel. I found the problem first by checking my fuel pressure. It only had about 52 pounds, which some say is alright. ( I found 60 is more like it, which I now have ) However when the pump built this pressure it immediatly lost all pressure in a few seconds. ( supposed to hold for at least 2 minutes ) This led me to check the fuel pump which after I straightened things up it ran like a top.

Replying to: pauls_boat (Oct 01, 2008 6:46 am) Sorry we're still at a loss. Can't figure out anything with my 95. My problem wasnt starting it was with keeping it running as you accelerate. not sure what to tell you.   Jerry
