It is because the Fuel lines going to your spider is busted. After you determine they're, Stop at a local parts store and spend 2 dollars for the proper fuel lines like I did. Don't pay over 2 bucks for these lines.

Insert washers into spider first. Then insert fuel lines. The small popet lines will break like glass, so try not to touch them. Don't let anyone tell you that you need a spider, Poppets leak in the head not the intake. Remove the Black cap from the top of your Intake, the round one. Take a light, If the driver side intake is clean on the inside then you have bad fuel lines, busted. If the passenger side is clean then you have a bad fuel pressure regulator which can be purchased seperately on the internet if you search for it for about 50 bucks.

I replaced the lines in about 2 hours, which means pulling to top half of the intake off, sometimes you can reuse the intake gasket if you're good, and use proper resealant.

Hey, make sure you post back. Also, the Coolant temp senser can cause your van to run badly and use gas.

You may need a tune up, spark plugs and plug wires. I would also consider replacing the fuel filter, if it has been replaced. Also check the air filter.

Testing a crank position sensor on a 1997 astro


If you don't have the van, it will be very difficult to test the Camshaft Position Sensor. Most reliable tests involve cranking the engine with the sensor installed and testing the sensor's output ranges. Most CPS's are magnetic and therefore testable conditions will be most difficult to achieve outside of the vehicle.

However, if you use a voltmeter, you can test if there is any resistance between terminals 2 and 3 (on a three terminal CPS). If the resistance is zero, this will only tell you that it is probably dead, but will not test if it has any other faults.

I hope this helps.

The control module is located just behind the ignition coil. Sorta hard to get to but we got it and the van is running great.

1997 Chevy Astro Van accelerates without pushing on gas peddal


You are right to be concerned about this behavior since it can definitely increase your stopping distance.
Either your cable has eaten its way into the inner tubing and is hanging up, or the mechanics at the throttlebody needs some lubrication.
With no engine running, have someone inside to press on the accelerator while you watch for movement of the linkage under the hood. Once you have located it, operate it by hand to see how it feels. If the linkage does not return to the stops provided, then use a heavy-duty penetrating oil to soak the moving parts. If it still hangs, then the cable needs replacement.
With the engine running, tranny in Park and the parking brake on, after you have lubed the visible linkage, have some one inside press on the gas and watch the linkage to see if it now returns to the mechanical stop. Carefully move it by hand to see if it is truly at the limits of its travel where it should be at an idle.
