Question about 1997 Chevrolet Astro
Posted by Anonymous on
Though this responce may be out of place n regards to an issue I had w/ my 97' astro van. It continued hearing a (rather annoying) clicking - ticking noise that would increase in speed (& just slightly louder) when I pressed on the accelerator, but when letting off, it would always slow back down to what it sounded like at idle speed. This went on for quite a long while, until I "shockingly" found that, in fact, that one of the wires (if I recall, it being the main coil wire) was arcing/sparking (clicking-ticking noise) on the transmission fill tube or dipstick tube. You could see the tiny spark as it was happening only at night or w/ very low light. Just fyi, don't do as I did, by attempting to move or touch the wires as the vehicle is running or even when cranking the engine over to start! Haha, okay laugh it up, but if it happens to you (or when) you'll surely find it to be a rather "shocking" experience!!
On a side note, I think this may have also been related to a problem I had (only on occasion for some reason) w/ the van not starting or turning over at all. So, after moving and securing the wire as they should be, (fastened to a plastic retaining clip/clasp that holds them in place), the annoying clicking - ticking noise had completely stopped occuring. If this could be the issue anyone is having, I hope this might help you out!
P.S. although mine held up for awhile, your wire(s) may need to be replaced w/ new ones. And, I suppose this could happen to almost any model vehicle really, so I wouldn't rule this out when troubleshooting similar issues.

Pick up a spark tester (it'll cost under 15$) . After installing the tester on one of the 2 rear right or left bank spark plugs, have someone turn the engine over and check for spark. If you have no spark, you could have either a broken timing chain or a broken cam-shaft. The only other minor item you didn't mention with regard to the ignition system was to make sure you have a good hot power source to your distributor. If these things don't work, it might be time to check that the carburetor or throttle body fuel injection (as applicable) is providing fuel.

SOURCE: no spark
Here are a couple of ideas. However, I think you've already covered most of them.
1. Remove the distributor cap and crank the car. If the rotor turns you're ok. If it doesn't turn then that's you're problem and you will probably need to change a timing belt/chain. (already done this)
2. Check the spark from the ignition coil by pulling the coil wire from the center of the distributor. Use an alligator clip to attach a short wire to the coil wire contact. Bare the other end of this short wire and set it up so it's sitting very close to the engine block. Turn off the lights and try to start the car. You should see a spark jump from this wire to the block. If you don't see a spark it's likely your ignition module (already changed) or ignition coil (could this be it?)is bad.
3. If you have a spark maybe it's not getting to the plugs. You may need to replace the distributor cap and rotor. (already done this) You can test if the plugs are sparking by pulling one, re-attaching the spark plug wire and seeing if you get a spark when you try to start the engine in the dark. Please note, the metal threads of the spark plug need to be shorted to the engine block to complete the circuit during this test.

You can change pick-up coil, you need to remove distributor (mark where rotor is pointing first) Then you need to remove pin in cam gear on end of shaft to remove gear so you can remove shaft from housing. Then you can replace pick-up coil. Install in reverse. Note when removing distributor rotor will move to the right as you lift distributor out, move rotor to right of mark you made when installing distributor back in.

Hi, I believe there is a computer problem. If possible check codes for no start condition. if you know the no.#1 cylinder at TDC (Top Dead Center) on engine then you will know no#1 distributor is. Good luck.
