Removing Plug Wires from '02 Pontiac Grand Prix, 3.8 Liter V6


often times the connection inside the plug boot gets corroded and it's almost impossible to remove the wires with out damage. when this happens I gennerally replace the wires anyway this saves you problems in the long run . the sparkplug wire removalk pliers are a good investment however they are only as good if the boots themselves are not siezed up on the plugs. I have had this happen alot over the 20 years i been working on vehicles. I usually just twist and pull on the boots till they come off and not worry about damaging them because they should get replaced anyway the new plug wires have a antiseize lubricant to keep from this happening in the future

I need to know the spark plug wiring order for a 2000 grand prix 3.1


. You're not going to believe this but the firing order is actually 1-2-3-4-5-6. Your particular vehicle uses coilpacks. Cylinders 1 & 4 share the same coil, 2 & 5 also share the same coil. And lastly, 3 & 6 share the third coil. Hope this helps.

Does the crank sensor send the spark to the spark plug and can i fix this? this is for a 98' pontiac gran prix


yes the crank sensor sends a signal to the computer to fire the plug through the ignition control module which then fires the coil.

1999 grand prix gt 3.8v 6 error codes 300 and 302


The PO300 code is random/multiple cylinder misfire detected. Sinsc you have the code PO302, that means that cylinder 2 is the one misfiring, usually a bad coil pack, or spark plug.
