I just replaced my coil pack 93 astro. Drive it 2 miles it backfired and died now coil is no good. Got another one same thing

when you said you replaced the coil pack this makes me concerned. When the truck cools off does it crank back up then die again, if so it sounds like the coil pack I know you replaced it but if the truck does as I asked you then replace the coil pack again from all the manuals that is what is wrong let me know please and Good Luck

Sounds like ur hitting a bump or something and you may have a loose ground wire causing it

Sounds like a crank or cam sensor or even a coil pack problem.Do you have any codes or check engine lite on?

It sounds like your ignition coil is overheating. Once it cools down it will fire properly until it gets hot again. Replace the ignition coil and you should be all set.

Not sure if you have a 1996 Cadillac Seville or a 1998 Olds Aurora but I would check the Ignition Coil Packs. One or more of them may need to be replaced. Also if you were working on the car and got the wires plugged onto the wrong coils then the firing order sequence would not be correct and this can cause a misfire or backfire conditon.

Ignition wires cannot rest near the primary wire harness of the ignition module, which can cause electrical interference and a no start condition or a misfire condition

On my friends 1997 Cadillac Seville it was easy to replace all 4 coil packs took less than 30 minutes and made the car run much better. Just make sure to get the firing order right. If necessary find a diagram of the correct firing order for you vehicle.

I have pasted a picture below of what an ignition coil pack looks like

I would first begin with a good tune up with new plugs wires cap, rotor, check coil. injector can be clog also, try to add bottle of fuel injectors cleaner and add 93 octane of gas fill it half way and run it til empty and see that will also help. If you have high miles like over 100k have timing check, its good idea to change timing belt every 75-10k miles, if it jump time due to worn belt, the car will not run properly.

Its not the packs, I am pretty sure that is the distributor in the engine, (the one the coil pack hooks up to) I thought I knew my stuff until a 15 year old neighbor kid came and fixed my sundance that way, that or its a loose battery wire. hope this helps, have a nice day, and drive that thing like it was meant to be driven!

Check that connections are clean and check battery voltage with a meter...If battery has less than 12v in it, likely you have a bad alternator.

Check and clean all connections to the battery. Check all electrical connects at starter also.
