What is the spark plug order for the v6 1986 chevy astro van

Is it a strong spark at the coil? If it is to weak it won't travel through the wire.

TAKE IT TO NOONE ELSE BUT A CHEVY DEALERSHIP AND HAVE THEM RUN A DIAG GIVE YOU AN ESTIMATE. I LOVE THOSE OLD CHEVY ASTRO VANS I HAVE HAD 3 OF THEM. SIMETIMES IT IS CHEAPER TO JUST REPLACE THE OLD VANS RATHER THEN SPEND MONEY ON THEM. THE LAST VAN I HAD I HAD PUT OVER 700,000 MILES ON IT BEFORE I GOT RID OF IT.

to change the spark plugs on the 2000 astro van you have to jack van up and take front tires off then you can go thru the rubber dust gaurd over the top a frame to get to the plugs

I would check the rotor very carefully. They tend to burn a hole through the plastic under the center tab. It's hard to see sometimes. The spark follows that path instead of to the wire terminals. You may just want to try a new distributor cap and rotor.

To set ignition timing, ensure that engine is at operating temperature, (190 degrees or above), bypass EST (electronic spark timing) by unplugging the single tan wire with a black stripe from the distributor. Ignition timing should be set at 0 degrees or TDC (top dead center). If not, loosen distributor hold down bolt and adjust, then retighten.

What you have to do is check and see if you have fuel pressure.You have to remove the engine cover to check it.If you don`t have a pressure tester then remove the air cleaner hose to the engine and spray it with carb.cleaner or brake cleaner.If it starts for a few seconds then it is more than likely a fuel pump.If it does not start then you have to check for spark at the spark plugs.Make sure you check more than one plug.If no spark then you have to check the distributor cap and rotor.Make sure the rotor is good and cap also.Things that can cause no spark are the ignition module,coil,and cap and rotor.Hope this helps.Good luck.

Vans can be tough. I am assuming you can get the old plugs out. You can try this trick to replace them, get a short piece oh hose and shove the top of the new plug into the hose. Then use the hose as an extension to install the new plugs, a hose is good since it makes it hard to cross thread the plug. Good luck.

Chk. all fuses, there is a fuse for injectors, If no spark at plugs chk ignition fuse and switch, and chk. fuse for e.c.m. Can't help with diagram. Parts dept. chevy dealer will print you one out.

buy a Honda or Toyota, they work
