1996 pontiac firebird V-6 starting problems

My car was running rough ,so I replaced the coil and a bad spark plug wire.It started long enough to get it off the ramps, then would not start again in ten minutes. It was getting plenty of fuel, so I check the wiring , according to the diagram it was in the security system, so I by passed it with a wire. It ran for a few seconds then died . I had a new key made at the dealership, still no help. I removed the wire I used to by pass the security , now it won't start at all. Any suggestions?

It may be the electronic key ignition part of the key ignition. try replacing that part. I had a camaro that did the same thing and that was the problem.

1998 pontiac firebird coil pack, will coil make it miss on 1 cylinder, 3800 engine, misfiring, have changed plugs and wires

yes, it can happen. check for spark from the number one coil using spark plug wire and hold it near a grounded point. it should be a consistent spark with engine running. compare to different coil wire for verification. those coil packs are partially replace able because each coil fires two plugs. replace the no.1 portion with a new one from parts store. 28.00

Continous code for misfire on # 6 cylinder. New coil pack, plugs and wires. Idles rough. Im lost now. Valve problem maybe???

Hi :) The best way to check out if it is a Valve problem is to do a compression test on all the cylinders and compare the reading. Some Valve Guides (brass or cooper tube between the head and the valve stem) wares out and allows oil to get in the cylinder and cause the spark plug to misfire.Some time a mechanic can put umbrella seals on the valve stems to stop the oil from doing this or a valve stem replacement done by a engine rebuilder.

97 Pontiac Firebird V6 Not Starting

The fact that it starts occassionally suggest that the problem is an unreliable spark or a fuel issue.
Here's a list of things that might solve your problem;
Check the battery, if it's weak your engine won't roll fast enough and your spark will be weak. Take it to the auto parts store and have it checked, most stores will do it for free.
If you're using old gas that could be the whole problem.
Check all the ignition wires, a loose connection or bad wire is all it would take.
Check all the ignition parts, worn or dirty parts can cause your spark to miss or fire at the wrong time or place.
Check the spark plugs and wires, fouled or mis-gapped plugs or bad wires can cause misfires and oily wires can cause your spark to go almost anywhere.
Check the choke, if it's not operating correctly it can throw your air/fuel mixture way off.
I know this is a lot of stuff to check, I tried to be thorough but I know I left out the most expensive fixes, Stator, Coil, Distributor, ect...
I hope this helps, if so, I'd be curious to know what the problem was.

1998 firebird 3.8 v6 92000 miles runs great until 3000 rpm then it runs rough and starts to miss

Same thing happened to my 94 firebird. Did your car run hot at any point? Mine overheated and ended up melting a couple of plug wires.
I replaced the wires (and plugs). That took care of the problem.

Have you ran a diagnotic check to see what codes are coming up?
Throwing parts at the problem will get expensive. It will also ruin other parts (Like your catalytic converter), when your engine is misfiring and not running properly. Your vehicle is an OBDII system, fix the problems in the order they appear (then clear, run and recheck)...meaning, one problem can cause another and so on. Fixing one problem may correct the other ones too.
You may get lucky with the shotgun approach, but usually not.
Run a diagnostic test, at least you'll know where to start looking for the problem.

I have seen on manyengines that using high performance plugs can cause problems like your's. If you used split-fire's or platinum 4 plugs change them back to OEM sytle plugs and your problem should be solved. If you used OEM plugs check that none are loose or cross threaded as this can cause a loss of compression.

Let me know what type of plugs you iinstalled and I can try to assit further.
