Moderately priced? Except that Dodge's fullsize van is only 20,481, GM's is 23,074, and Ford's 22,030 according to TMV. All seat eight just like the Astro, have nice headroom like the Astro, and get the same MPG and towing capability with a V6. To me, Astro's only selling point is AWD and that it is a minivan that retains some true utility (durability of body on frame construction, towing capability, cargo capacity even with the back seat being used by passengers) while not driving like a Taurus or Camry. (I like the ride of a real truck or van-- I know the soccer moms don't.)
#480 of 1889 Temperamental Starting Gremlin Found by 67firebirdconv Oct 20, 2002 (7:00 pm)
I am posting this to those to those with a possible TBI V-6 firing then shutting down. Today I had the starting problem reappear, but this time the SES light stayed on when I finally got my van started. A quick trip to AutoZone hit the jackpot. Their error reader indicated "P0108, MAP sensor circuit high." The MAP adjusts the fuel flow pressure for ignition based on the load of your engine, and it is regulated by the engine's vacuum. From what the technicians told me even a minute vacuum leak will cause an error. Anyhow, after taking the shroud off inside the van, the MAP is easily accessible on the top of the engine. After resetting it both electrically and physically (it was a little loose), the SES light went out and the van fired with no problem on the first crank. Saved me $42 for now, but time will tell.   Hope this helps someone in the future who has these problems, it's a cheaper fix than a fuel pump replacement.
#484 of 1889 Safari AWD Problems - HELP by bicyclist1 Nov 08, 2002 (3:44 pm)
Having a possibly intermittent problem with my front wheels not engaging on a 99 AWD Safari. At times I'd swear the AWD is working, driving up long,steep loose gravel driveways without missing a beat. But some times my rear wheel will spin and I don't go anywhere, like on a patch of sloping wet grass. Took it to a dealer who plugged in his computer(scanner) under the dash to read the "engine" codes. At first he said I had no front wheel sensors, then found they were there but not picking up any signal. He took it for a test drive and came back saying only the rear wheels were engaged. He put the van back on the lift, started it up, and just the rear wheels were turning. Then he "cleared" or reset,the front wheel sensors on the computer/scanner and presto, all 4 wheels were turning . He decided everything was OK, but couldn't really explain it. I drove home to my favorite slippery spot and the rear wheel just spun, with no front wheels engaging. Went to a 2nd dealer, don't know exactly what he did, but called me over at the end to show all 4 wheels turning up on the lift. He claims the front wheel sensors the other dealer looked at were for the ABS brakes and were not related to the AWD.
#488 of 1889 2000 Astro - Fuel Pressure Regulator by bapeters Nov 19, 2002 (7:22 am)
I just had to replace the fuel pressure regulator on my 2000 Astro with only 42,000 miles. Has anyone else seen a similar problem? It alarms me that this type of repair was needed at such low miles. Is this a known problem with the 4.3 liter engine? I am hoping that Chevy will "help" with the costs of these repairs. Any feedback would be appreciated.
