My car has gas and a good battery when I tried to start it the engine backfired
Has anyone given it a tuneup lately? I ask because it sounds like the distributor may be 180 degrees out of align. Another possibility is that someone has adjusted the timing by loosening the distributor. This could be a simple as the wrong spark plug wires connected to the wrong terminals on the distributor cap. Check the firing order and make sure that the wires are leading to the correct sparkplug. I believe you have a V6 so here it what I have found.
Your firing order should be 1-4-2-5-3-6 . As you can see, they start at the back left, then front left and proceed back to front in order. Standing in front of the vehicle the back left plug is # 1 moving from left to right the next backside (closest to the windshield) plug is #2 then #3. The front most plugs are from left to right #4 , 5 and 6. The distributor cap should have a "1" on it indicating #1 cylinder/sparkplug. Check the wires and make sure it is wired right. If after all this it looks right, or you have a 4 cylinder let us know. You may have a sensor problem and that is harder to diagnose.
Checking the timing is a little hard and requires a timing light. If you dont have these tools you should probably let a shop do the work for you. Good luck.
