#115 of 155 GMC Starting Issues now won't run :( by mklein1 Oct 03, 2008 (7:24 am)
#116 of 155 GMC Starting Issues now won't run :( by mklein1 Oct 03, 2008 (7:24 am)
Long story short. Trouble started after a very slight roll over. Wouldn't run in the rain. Progressed to very hard to start. Ran fine if you could get it started. Now won't fire at all. Family's favorite vehicle. Owned since new. 2000 GMC Safari 133,000 miles. New coil, new distributor, new ground wire to coil. New wires and plugs. Fuel pressure 50 psi. Tapping the key when starting used to help start it. Fully charged battery (keeping a charger on it) or jumping seemed to help. New battery didn't make any difference. Any ides? Thanks

Replying to: gilassilver (Nov 25, 2006 8:02 pm) I know exactly what you mean. Needing a fuel pump for my 94 Astrovan I checked with the parts dept at a local Chevrolet dealership. They wanted almost $1000.00 for a new pump. I laughed, hung up and called Autozone, where I bought a new pump (including all necessary gaskets, etc.) for just over $80.00 including the sales tax. In short, if you call around and check the prices at Autozone, Checker Auto, Pep Boys, Napa, etc. you'll likely save some money.   Charlie Replies to this message: Steve_01 (Dec 16, 2008 6:48 pm) chevyman0707 (Dec 28, 2008 10:15 am)

"called Autozone, where I bought a new pump (including all necessary gaskets, etc.) for just over $80.00 including the sales tax" Did you mean $280.00? I just checked AutoZone's website. They want just over $280.00 for a 97 Astro fuel pump assembly.   Steve Replies to this message: chevyman0707 (Dec 28, 2008 10:15 am)

Replying to: Steve_01 (Dec 16, 2008 6:48 pm) yeahi have a 94 astro 4.3l i just went to autozone and picked up the pump with the gaskets for $54.00 and a new fuel pump strainer for $10.99 so i have no idea what your talking about steve.
#121 of 155 Here's what I'm talking about... by Steve_01 Jan 01, 2009 (12:22 am)
Chevyman, I was just wondering if the guy made a typo is all. Thats great that you guys can buy a $280.00 fuel pump assembly for $54.00 or $80.00. Here's the link to the Autozone page, http://tinyurl.com/85nt3c Must be that the 97 model year pump is just more expensive... Replies to this message: Steve_01 (Jan 20, 2009 9:25 am)
#122 of 155 astro fuel pump by 1shadetree Jan 03, 2009 (12:02 pm)
I've had the same prob w/ my Astro not starting. replaced the coil. took it to shop. Shop told me it was low pressure from fuel pump. They got it running but said it ran very rough. Was advised (strongly) not to use aftermarket pump. found Delphi (OEM) fuel pumps from 200 to 465 bucks. Long story short, I replaced fuel pump and and filter and it isn't the problem. Checked fuses and they're ok. Replaced plugs, wires, cap and rotor last spring. will turn over fine and after about 3-5 seconds it kind of hangs up (bogs, burps, but not cough).   Any other ideas? thanks.

I poured a little gas down the throttle body (I'm no Norman Einstein) and it still didn't even try to start, even though when I opened the butterfly with the pedal I got a cool blueish orange flame. Obviously I have fire! I'm beginning to think it may be a cam or crank position sensor? If it jumped time or broke the timing belt, what would be the symptom? I really don't want to drag it back to the shop, but we need it back running asap.   Any suggestions?

Replying to: 1shadetree (Jan 03, 2009 1:34 pm) It's ALIVE!!!! Yes it's running. Even though I had replaced the distributor cap and rotor last spring, they had gone bad. Look for a green powder inside the cap. It's corrosion. Two of the cylinders were not getting fire at all, and instead the cap was "shorting out" sending a spark to 2 cylinders at the same time causing it to cough. Anyway, it's all fixed now AND I have a nice new fuel pump. Replies to this message: Steve_01 (Jan 21, 2009 5:26 pm) 1shadetree (Jan 22, 2009 5:19 am)
