Oil pressure switch? Hmmm....well, why would that allow for the vehicle starting, running for a bit then dieing? I thought the oil pressure switch was just an indicator light on the dash, or a gauge telling you when you have low oil pressure? How would either of these account for the problem? Many have told me to replace the Ignition Module, and the pick up coil for starters...problem is,the Module isn't exactly cheap...costing approximately $122.00...so I am not keen on replacing apart that may not be the problem.....could also be a bad wire on the Ignition Coil, or bad coil....so I am looking at replacing those two, and putting in new plugs and wires....the van needs them as proper maintenance anyway....I am stubborn about taking it to a mechanic, since every single place I've spoken to, has indicated it will be:
$40.00 for the tow
$70.00 for the scope
$35.00 for the no start
varies per location, but they all want $100.00 minimum to start...sheesh...I could buy wires, plugs, Ignition coil and Pickup coil for $100.00.....and the vans problem would either be solved, or the van would be better off with new parts, most of which it needs eventually anyway....
The only thing that would be left, is the Ignition Module, and if that is the culprit, I would be ahead of the game, having put new parts all over the engine......
I was just hoping someone couldreally narrow it down based on the info provided.....thanks very much for your suggestion though....are you sure it is called the oil pressure switch?

Need some details on how to find the distributor, rotor and camshaft sensor. 2002 Astro- haven't been in a car this new before and don't see what I'm used to seeing!

The Haynes manual wireing diagram calls it the oil pressure switch and sending unit. It is wired to the fuse block under hood and fuel pump relay. If it detects alow oil pressure it shuts off the engine to keep it from damaging. If could be getting a false reading. The van starts and then stalls when it gets a low reading. That was just one posibility.

You need to remove the engine covers inside the van. The distributor is on the back of the engine. The rotor and camshaft sensor is under the distributor cap.

Thanks. Went and bought a manual so I won't have to ask such stupid questions again.

Hi!I had to put in a new front case a while ago because a mechanic that had to replace the two cooler lines that went over the left shaft removed half the case and the shaft connection to get the lines in..forgot to tighten the bolts on the 6 bolt plate axle connection plate AND the case bolts were only handtightened.It was 6 months before I started hearing the grinding and crunching of only 3 bolts(of 6) left holding the axle on and all the fluid gone in the case.Needless to say,I do ALL my OWN work now,haven't found a trustworthy mechanic in the Seattle area for at least 15 years!
My left bracket is still hanging in there by the bottom weld and will be welded this week,took out the fan,shroud,and a lot of other parts to get to the top.The right hand side bracket I've replaced already..still need to fix the torn boot on the axle from mine falling..Do they make just replacement boots? or is it like the transfer shaft where you have to buy the entire thing for $300+ to fix just the boot?..I got a new replacement shaft but they did away with the boot and put the u joint right in front of the back mount..The problem?I had to buy a $35 wrench from snap-on because that weird socket wouldn't fit the 4 bolts now,u joint in the way,no room....hopefully I'll have the car back on the road this month.With gas at $3+ per gallon,my 10 MPG one ton van is draining my wallet! I might try taking the shaft back out,simple enough.
Has anyone tried contacting GM about the design flaw,asking them about how many they have fixed like that?(like they would tell you!)..seems to me to be pretty dangerous to hit a bump at 70 mph and have the front end collapse..appears to be a common problem with older awd astros and not from driver abuse!

I tried to talk to Gm but of coarse they NEVER heard of the issue! ya right, The definatly Know about the Transfer case quality but they wont admit to that either. Since the Transfer Case is the underliying issue with the Breakage Myself and the other gentleman experienced Its Really our fault because we didnt replace the $1500 case before it damaged the driveline parts.Well Im sure you can hear the sarcasm in that statement. Luckily I am a mechanic but since we bought it for 1000 bucks we have put in over 3000 since then! All parts cost as labour was mine only!However My wife and I love the van and we really dont care at this point I couldent bear to part with it as I have so much work in now. Some of that money was spent on upgrades like- Kyb MOnomax shocks,k&N air filter, Ride rite air bag rear suspention kit, Yokohama Lt tires, stereo, driving lights etc. we use it for two week camping every year and tow my tent trailer and small boat 300 miles each way and with three kids Im afraid its indespensible to me! I guess that Means More work in the future huh! CHEERS RON Y.

I bought a 2000 awd Astro 2 years back. Good handling in Pennsylvania weather but have problems with ABS brake system. Pull ABS fuse and brakes work well. A mechanic said it was a sensor problem but I just had a similar problem with my 2002 Chevy Blazer and they replaced the computer board. I think I'd suggest looking at something else. When mfg. don't correct problems year after year or offer a help line for we backyard mechanics, I say "let them all go under"! They are not loyal to us, why be loyal to them? ANYONE KNOW WHERE THE ABS BOARD IS LOCATED IN A 2000 ASTRO AWD???

I suggest that we start a campaign to let the "big three" auto makers know that if they want us to buy their products, they need to offer us support here in the field. Not everyone can afford to constantly drop money at the dealers while they try to fix a problem that has been around for years. I would be loyal to any mfg that would step up and offer an "after market" hand at resolving issues. I didn't buy their vehicle to make the dealer rich on service and parts! What say you???
