First check to be sure the vavuum lines at the throttle body are in there correct places.
on the main pulley of your engine, the one on the crank shaft there will be a little notch on it. mark the notch with some chalk or a dab of white paint. then loosen the bolt that holds down the distributor until you can turn the distributor. turn the distributor a little bit, snug the bolt up and try it. once you have the car running you will need a timing lite to set the timing to the correct timing mark. which should be 8 degrees before top dead center for you car.

1986 pontiac 6000 2.5L. backfired 2 times then quit

I owned an '87 Chev.Celebrity once, from about year 2000 to 2005, thereabouts,. one of my favorite cars. It had the 2.5L, too. A sister car to your 6000. Mine had been a taxi in Great Falls, MT, so it had had a super good maintenance schedule followed fanatically. I'm pretty sure the engine had been replaced not too many years before I bought it with 250,000 miles on the odometer, from a private individual. Was sure a nice car, and the odometer made it past 400,000 miles, with reverse gear gone out the last two years I drove it. (True story: always got 26-27 MPG from the day I bought it. When reverse went out, I started getting 30 MPG- I figured I eased up some friction-lol,) By then the engine was sending signals it was tired and going down too. I thought it wasn't worth repairing considering the cost involved, so off to the crusher!
Backfiring can be a symptom of valve train problems. Especially so, if the engine is getting only the required amount of gas to run good. The 2.5L has a timing gears set-up, no timing belt or chain, so if not noisy, probably good. Check your timing with a timing light. Look at the cone pattern of the fuel spray out the injectors-look down the throat of the throttle body with someone cranking the car over, the gas should be spraying out in a fine mist cone pattern-if it drips or runs, it's getting too much gas. If it looks good, well, how many miles on it? You might want to do a compression test to see about the internal condition.

96 jeep cherokee backfire through throttle body

I am going to take a stab at I think you may have a head gasket that has blown out. The head gasket will cause a lil white smoke, and make idling extremely rough. Sometimes water will fill up in the top of the cylinder in the compression chamber when this leak, even minor occurs. That would explain some of the compression issues. Obviously with no compression it will not run properly or even fire if there is water vapor pentrating into chamber mixing with fuel giving you that white smoke/steam.

These are somewhat time consuming to change, but not difficult. The backfiring is caused by the computer trying to compensate for the firing issue. The computer when you change the head gasket is easy to fix. After repairng gasket, try to start the car a few times but not allowing it to run as it will just continue backfiring. Turn key off, let the vehicle set about 30 minutes or so, then go back and the vehicle should run properly again.

Let me know,

Where do i locate the heater core in a 1991 pontiac 6000le

The heater core is inside the heater case. It is the same plastic case that houses the blower motor. Usually they are replaced under the hood near the firewall or under the dash. I would look at the free online repair manuals provided by parts stores such as . They should have the info you need for your particular model.

Problems refiring 99 pontiac grandam gt 3.4 v6

That is an intake backfire, meaning you have the valve timing wrong. Not quite sure right now on what it should be but check timing belt position and valve timing gear positions.
