Miss fire on cylinder six on a gm sierra 1500 5.7 1996

Check compression on that cylinder. All the items you replaced could have been tested to see if they where working correctly. If they where than there was no need replace them and the next logical step would be to check for a mechanical failure rather than an electrical or engine management failure. In other words if the engine is not solid mechanically than there is no reason to replace electrical parts to try and solve the issue.

5.3 liter Chevy engine #1 Cylinder not firing at idle

My opinion...

Year? Miles?

There's no way I'd dive into a "HEAD GASKET"
diagnosis without pressure testing the cooling
system and (wet/dry) COMPRESSION testing
the whole engine...

Even if it is a "HEAD GASKET"... the entire engine
might be ready for a REFRESH... and tossing a new
Head gasket into a TIRED ENGINE not insubstantial
(a lot of wasted time & money)...

Come back with some compression numbers...

but don't bother with any of this if your engine oil has water in it.

Miss firing and passing raw fuel through exhast , replaced 1 coil , all new plugs and new plug wires

check the fuel pressure regulator... it is the small round chrome cylinder shaped thing on the fuel rail...unplug the vacuum hose from the top of it and see if there is fuel in the hose if there is you will need to replace the fuel pressure regulator.
hope this helps

My engine misses, and I have the check engine light on.

Could be many different things on a 4.6L Ford. The best way is to have it checked by a scanner. It will narrow down to what cylinder or cylinders have a miss-fire. If the engine light is flashing, do not drive it. Possible problems, Low fuel pressure, spark plugs, fuel injectors, mass air flow sensor, o2 sensors, bad head gasket or head, low compression on a cylinder.

#1 plug is miss-firing.I have replaced plug and wire,but keeps miss-firing only on#1 plug.have been told that coolant is possibly getting in #1cylinder.also I have been told #1 coil could be bad.witch is...

Could only be a few things. The coil #1, Fuel injector #1, Stuck intake or exhaust valve, or blown head gasket allowing coolant into cylinder #1. Use a spark tester to check the spark coming out of cylindr #1 if checks good then ohm test the injector when it is warm. Check other injectors to compare. Do a compression test on cylinder #1 and test other cylinders to compare. If cylinder is low compression suspect valves and or head gasket. If compression is low then het a leak down tester to test if a valve is broke or sticking. On your sable i would suspect injector or coil most likely.

Jeep just had head gaskets put on. its miss fireing between cylinders 3 and 5. motor has vibration n exhaust is makin poppin noise . what could cause this

The easiest thing is to make sure the firing order is correct with the spark plug wires. You may have 5 and 3 spark plug wires crossed. Also, was this vehicle running ok before the head gasket repair???

Hey guys i got 540i 98 and i got a few problems! i know something a bout mechanical but never in bmw i got miss fire in cylinder 5 and 6 is this car single coil or just 1 for all of them? also...

mcdevito75 Here, The mechanics itself even in a BMW are about the same, not putting down BMW though, the mis-fire in 2 cylinders next to each other could be a head gasket, or something related to the ignition system. If you can remove plugs 5 & 6 if they appear white, it"s a head gasket, a little wet with gas then it:s ignition. Have your local auto shop check it out for you.

Miss-fires especially when cold, hesitates when you excellerate

I had this happen recently to our Buick rendezvous. Unfortunately it was due to a blown head gasket. It goes away when warm due to the block expanding. Coolant was getting through into the cylinder. Hopefully this isn't your problem but the same symptoms. We had replaced plugs, wires, and an 02 sensor before comfirming it was a head gasket. Luckily ours was covered under warranty.
