#1834 of 1889 Re: No Power stalling once warned up [csparrazza] by jferrantelli Jan 24, 2009 (3:53 pm)
Replying to: csparrazza (Jan 10, 2009 6:33 pm) Hey Guys how is it going. I could'nt resist in sticking my two cents in one this one. My 1998 AWD Astro did the same thing AFTER the fuel pump was replaced by a shop. I went berserk trying to find the problem. Stalling, towing to shop, etc. Here is the test ... Fill the van FULL of gas to the top. Drive it around. I guaranty you don't stall or sputter unitil you get under half a tank or less of fuel. Try this and let me know. My problem was the non-GM (aftermarket) pumps that you get from everywhere but the dealer, have a pickup (Not to be confused with the screen on the bottom), but an actual hose with a metal quarter sized round pickup that snaps into the channel where the screen is. Mine came loose and hovered half way up inside the pump body. When the van had less than a full tank especially on hills and turns it would sputter and stall because the quarter size pickup was sucking air instead of fuel. This literally drove me crazy for 8 months until I got disgusted and dropped the tank myself and took out the old pump and found the problem. I bought a new GM Pump and no more problems. You can reseat the pickup in the bottom of the pump but I don't guaranty it will stay seated..   Good Luck and let me know. My van runs great no problems at all NOW !!!   Joe Replies to this message: csparrazza (Feb 05, 2009 6:43 pm)

Replying to: csparrazza (Jan 10, 2009 6:33 pm) You might check your fuel pump realy on the firewall ab0ove the heater blower,or check fuel pump pressure when it stops. i'm seen these fuel pumps quit pumpimping after they warm up, I just replaced one on my daughters monte carlo last summer for the same problem.                                   DLM1
#1836 of 1889 REF to 1832 Stalling Issues by csparrazza Jan 27, 2009 (6:02 am)
Thank you for your replies so far I will look into some of your Ideas. I did end up getting an OBD code of 32 which is the EGR Valve. I have checked the ground and reference voltages to the valve they are fine, so I am going to replace the EGR valve. Got a good deal On Ebay new Delphi for $70. Waiting for it to arrive this week. Hopefully this will do it. I have also wondered about the Autozone fuel pump if it is working properly but the pressures are good. I will post the results for those interested.

#1837 of 1889 GMC SAFARI 03 gear shift display by reyahk Jan 27, 2009 (1:28 pm)

#1838 of 1889 Astro rough idle dive stall by blackpacific1 Jan 28, 2009 (11:16 am)
My current symptom is the van will start, rough idle, I can rev it some, but about 7 seconds later it will dive/stall.   I need to know what the fuel pressure is at the back side of the TBI. I also wonder if the EGR passages can be blocked temporarily to see if the EGR is dumping hot gas in the intake at the wrong time?   I've replaced the plugs, wires, cap, rotor, coil, IAC valve, computer, coolant sensor, cat. I've had the ignition control module tested, the EGR tested. The dealer replaced the fuel pump, but I wonder if it was done right. I replaced the injector pod with a rebuilt one.   Aside from low fuel pressure or EGR malfunction, the only thing I can dream up as a possible cause is hot gas leaking through to the intake passages at the intake gasket. I've run a complete set of pressure tests and leak down tests to rule out the head gasket or burnt valves.
#1839 of 1889 Body parts question by Clydesrose Jan 31, 2009 (4:27 am)
Will the body parts from a 1988 Safari Van fit on to a 1987 Astro Van? Our 1988 was hit and we purchased it back from the insurance company. We purchased a 1987 Astro Van and would like to know if the body parts are interchangeable.   Rosemary Replies to this message: dlm1954 (Feb 01, 2009 4:28 am)
#1840 of 1889 shift lever display by reyahk Jan 31, 2009 (6:25 am)
everytime I shift from park to D or any other position the shift position display on the cluster will show something else eg if I move to R the display shows P ,if I move to N it shows 3 when I'm in D it shows R etc everything else on the cluster works fine any idea if it's a sensor or module or the actual cluster?

Replying to: Clydesrose (Jan 31, 2009 4:27 am) They should, these vans didn't change much from year to year, but you can go to a Astro parts site for body parts and check the part numbers to see what will fit.                                      DLM1

Replying to: reyahk (Jan 31, 2009 6:25 am) If that's a electronic dash and I assume it is, the circuit board is probaly bad, in which case your talking a dealer item which means big bucks. If I were you I would live with it or go to a junk yard and pull one, it will save you a lot of money for a part that rarely goes bad.                                         DLM1 Replies to this message: dlm1954 (Feb 04, 2009 9:39 pm) blackpacific1 (Feb 05, 2009 6:20 am)

Replying to: reyahk (Jan 31, 2009 6:25 am) I have an older 1993 Astro. On mine, the shift indicator is driven by a cable that clips to the steering column. When you shift, the cable is pulled or retracts. I know about this cable, because when I was replacing a turn indicator switch, which required the steering column to be lowered, I managed to snap my cable from its mount in the instrument cluster. Rather than fork out for a new instrument cluster, we have learned where the shift lever should be for 4, 3, etc.... Your cable might be binding on something, if they still use this method.
