#1038 of 1889 '94 2wd Astro Problems Please Help by dragon300zx Sep 09, 2005 (9:59 am)
Ok here is the deal with this very troubling problem I am having.   Astro Van '94 180,000 miles 2WD When I am at a speed in excess of 50mph this problem accurs.   At any speed above 50MPH when I take my foot of the gas and the vehicle begins to slow down I get a low pitched rumbling sound that sounds like it is coming from the rear of the car. It also feels as though something it's holding the vehicle back and not letting it run as smoothly as normal. Once I hit 80MPH the vibration and sound is constant when my foot is on the gas. The sound and vibration only occurs for the first 5mph of decceleration. So if I am doing 70mph and take my foot off the gas I get a low pitched rumbling sound (rumbling, grinding, mechanical type sound), a slight vibration, and it feels as though the vehicle is hesitating.   So far I have: Changed the universal joints. Checked the rearend and the fluid seemed good (I replaced it) and there was no metal shavings at all in the fluid, or on the magnet. Checked the trans, fluid seemed alittle burnt, replaced the fluid and fluid filter, gasket all that good stuff. Had the tires rebalanced.   Problem is still there and I can't figure it out. Neither can anyone I have talked to already.   Has anyone has this problem? Anyone have a clue as to what it is? Help....... Replies to this message: alenarcik (Sep 21, 2005 4:56 pm)

94 astro barely runs if at all, refuses to start at times. reminds me of when i had to replace the fuel pump in the tank...man was that expensive! I wont do that again, which leads me to ask, can i put an electric pump in to assist the tired tank pump, somewhere in between th tank and the engine? any thoughts...thanks Replies to this message: cob (Sep 12, 2005 8:16 am)

Replying to: rileysdad (Sep 10, 2005 9:24 pm) I would think you could mount one just outside the front of the tank to the existing line. You should probably wire it to a toggle switch on the dash to turn it on and off and disconnect the one in the tank that is not working correctly. I am not sure if you can get the gas to run through the bad pump. I had a Holly electric pump on a 1979 Camero that was wired to a switch and it worked great. Make sure you have a fuse in line.
#1042 of 1889 94 astro / bad fuel pump by rileysdad Sep 13, 2005 (10:22 am)
has anyone replaced the fuel pump in the tank? what is the procedure? any special tools?   The van is not worth the money to have the dealership do it...so I must tackle it myself.   Any help is greatly appreciated! Thanks, Sean Replies to this message: tkw (Sep 14, 2005 10:54 am)

Replying to: rileysdad (Sep 13, 2005 10:22 am) I didn't work on mine but watched my mechanic doing it. You have to drop the gas tank. It'd be tricky if your tank is rather full and didn't have the use of a transmission jack. The fuel pump is located on the top side of the tank. Replacement seemed straight forward except you'll have to be careful when disconnecting the fuel line. It's pressurized even when it's not running.

#1046 of 1889 "The Late Great Astro" by topsea Sep 19, 2005 (2:31 pm)
In another 50,000 miles I'll be ready for a new Astro. Too bad there isn't anything out there that has the volume and ability to handle a large load. My last 2 Astros have had AWD which I have come to love on nasty winter roads.   My only choice right now is the full size GM vans with Awd. That's it! The Dodge Sprinter is really ugly and isn't available in AWD. Ford's full size isn't available in AWD. I need the seats as well as the cargo area when the seats are out. I really like the dutch doors on the Astro. Too bad GM couldn't keep the Astro platform alive. Anyone with any ideas for a replacement?
#1047 of 1889 87 astro fuel gauge problem by lukesdad Sep 20, 2005 (12:10 pm)
I recently purchased an 87 chevy astro and noticed the gas gauge doesn't always work. In fact the last 2 days it doesn't work at all. The books don't say anything about the gauge. The only thing I've been able to figure out is that the gauge is connected to the fuel tank via the sender unit. Is it something anyone has any experience with?
