My mechanic told me that fuel pump malfunction would not register a code. When My '98's fuel pump failed just barely out of warranty, it stalled intermittently like yours. You can try knocking on the side of the fuel tank with a mallet next time it stalls. If it starts again, you can zero in on the fuel pump and do more testing. BTW, a plugged fuel filter will have similar symptom too.

Wow! You are having exactly the same symptoms as my 2000 Astro with 96,000kms. Same stories from my favorite shop and also the Dealer. I have now spent $400 on a tune-up replacing plugs, fuel filter, air filter, distributor cap, and rotor. No improvement!! Plus $200 diagnosing the problem with the same results. Suspect it is the fuel pump too. I just hope it will fail one of these days so I know for sure! It is expensive to pull the tank and replace the pump on a guess! It just ran for a whole week with no problem and then started acting up again yesterday! Let me know if you have ny success solving your problem!

Yesterday I install a fuel pressure gauge and it will sit on the floor of the van has long that it will take. Right now the fuel pump is working perfectly up to 60 psi during priming time; 52 - 54 at idle; and up to 60 when cruising. Now I'm just waiting for the van to go crazy and see if it is really the fuel pump. Honnestly I not so sure because of the unrelated link be twin the disconnection of the air flow control meter and the fuel pump when it wont start.

That's great. I was thinking of doing the same thing to verify fuel pump problem. I will keep my credit card in my wallet until I see how you make out! It may take you a while as mine just ran super for a week and then started acting up again. Please keep me posted.

ASTRO AIR CONDITING by steely

NO AIR FROM THE DASH VENTS. Small plastic vvacuumtube from the condensior towards the dash. Instead of replacing the tube I found the crack/break and used srink tubing (Radio Shack $.50) to fix the gap. 4th July weekend, took 5 mins to fix, how long will it last? Better then spending the day pulling of the dog house. If it wasn't fixed I'd be kicking my dogs out of their house to sleep.

Have someone check the b-pillar seam weld. It is at the top of the Pillar right behind the driver door!

I finaly found the problem. The pink (hot) wire for the crankshaf sensor was broken (cut loose) in the plastic envelop. They were not contynuitie All that because the wires from the sensor were to tied around the big ground connection near by. Even they other wire (yellow and blank) were half cut. Tank to Haynes electrical diagram.
