Re: 91 astro vin z fuel cutout/stall prob
Well I took the igintion module out and took it in to Advanced Auto and had them test it. They tested it 6 times and it came up good every time.
I'm going to give Ask a whirl. If I find a solution I'll post it... thanks for al your help. If anyone has a brainstorm in the meanwhilst, be sure to post in case I get nowhere on ask. |

Re: 91 astro vin z fuel cutout/stall prob
Come over to http://astrosafarivans.org/ and post there. Those guys know there Astro vans inside and out. I'll warn you they may try to convert you to a V8 to solve your problems though.
 You might also try www.autozone.com and go through the process of registering and looking at their repair info links. They might have the diagnosis from the manual in there for you....

Re: 91 astro vin z fuel cutout/stall prob
I'll give that a try.
The justask guy had me spray carb cleaner down the throttle body while it was not starting. I should have thought of that. In any case it fired so the problem is still on the fuel side... thx, |

Re: 91 astro vin z fuel cutout/stall prob
OK folks,
We may have a resolution...sigh.... We took it in to shop today - wouldn't you know it, it ran fine the whole way. They had trouble getting it to act up enough to track it but ultimately the found they could get a fairly repeatable issue by letting it get warmed up and then shut it down, and when they restarted it would frequently be hard-starting. at that point they said they were able to see that they were losing the "noid" bump or signal that causes the injectors to fire. They wound up replacing the ignition module. That kills me.  I had it out and at the parts store and nearly decided to replace it twice. Instead I paid someone $200 for the priviledge!Of course until we've driven it a couple of days, we won't be comfortable. But it seems to be running properly for the moment. Thanks for all your help!!!! I hope the information here (assuming it's fixed) can help some other poor guy in misery. If anyone is so inclined, you might post an explanation of the whole "noid" signal thing. I have an o-scope. If I know what I'm looking for, maybe next time I can find it. Thanks again $200 bucks lighter |
