Firing order maybe ?? HELP
ok well i was taking spark plug wires off trying to solve a problem , and now the car is missing really bad and will not start up, well i will but it will die soon, maybe i got the spark plug wires mixed up , does anyone have a diagram on which spark plug wire goes on the opti and on the spark plug?

* firing order
* ohms for each plug/coil wire (and inspect them)
* spark plug gap
* check all wire connections.
* check the O2 sensor wires
* check all injector wires
* if you removed the intake tubing, be sure to check that
the elbow/tube connections are mated properly and tight.
* check all vacuum lines.
If it ran fine before disconnecting things, and now it doesnt run fine,
then it's got to be something that was disconnected. Either that or it's
an incredible coincidence that something else went bad.

Well it ran fine then I found that spark plug and took it out and re gapped it and it started missing really bad so I got a new spark plug and its still missing badly and won't crank or will start to crank and then just keep turning over!! What will the icm do if it goes bad?

ok i do have spark at the spark plugs i tested them with a spark tester!!!! what do yall think it can be? my car is on jack stands in the front , so the front is sticking up and my gas gauge says it has little under 1/2 of tank of gas...so what do yall think it could be?

If your gauge it reading under half tank, you have closer to 1/4 tank ( Im sure you know about our gas tanks shape and fuel gauge inaccuracy etc) it could be its not getting to the pick up if you have the front end high enough. set her down on the ground and see what ya get. You can always jack it back up if that doesnt do anything for it. Have you checked for fuel pressure at the rail?

I burnt a plug wire within the first twenty minutes after my long tubes install. I thought I had routed everything the right way when I first installed them but I was wrong. I ended up burning 3 more wires over the course of the next week before I got it so that the wires would not move around at all and touch the primaries.
Pop open the hood at night and watch for a fire works show. If you don't see anything spray some water around the wires as it idles at night.
When it comes to wires, even a little crack in the insulation you may not even see can allow the voltage to arc out to ground. Under load the spark is more likely to jump out of the wire due to the fact that high cylinder pressures make it harder for the voltage to jump the spark gap, electricity will always take the easiest path to ground.
