pull the spark plug out of number 1 hole. then turn the engine over making sure the piston is at the top of the number 1 hole. pull the distributor cap off make sure the rotor is pointing at number 1 . replace spark plug. distributor cap. see if that baby fires up now
I own a shop, and have seen this, fixed this, and know what it takes to get it running. I got one running that had sit for 30 years. It smoked like the woods was on fire, but I got her running. What happens is the rings are rusted, and stuck to the cylinder walls, and if you aren't careful you will break a few of them. Remove the spark plugs, drain the oil leaving the drain plug out, and fill the cylinders with WD-40, or sea-foam. Anything that has a rust inhibitor in it will work well. Let it set with the cylinders full for several days. It will drain down into the oil pan, so you need to keep putting it in there to let it do its job. Use a breaker bar on the crank bolt, or even better if you can use a long screw driver on the flywheel from under the car with the dust cover removed. You can pry the flywheel back, and forth with much more torque than you could ever with the harmonic balancer. Besides you may twist the bolt off in the crank, and it will for sure be scrap from there. Keep moving the flywheel/flex-plate back and forth for a long time, so as to not break the rings. It will come free after a long time of this, but if it is salvageable, you will only know this once you get it running. Once it frees up, you will want to turn the engine over by hand for several rotations to push the oil out of the cylinders. Let it set for a few hours in its new position in order for the rings to free up some from the pistions, as you know they are stuck there too. Replace the drain plug, the oil, and turn it some gently with the starter for about two revolutions each time, while letting it sit between turning for a few minutes. It should spin pretty fast with the spark plugs out, so you don't want to turn it so much it breaks the rings. The rings will cut a new pattern in the cylinder walls, so it's a good idea to give it more WD-40 to help wash the build up out the spark plug holes. Leave the spark plugs out until you get it freed up. I forgot to mention, when you replace the oil, purchase a quart can of some stuff called Riselone, and add to the oil, but don't overfill the crankcase. Let the engine sit over night, and if possible install some new spark plugs. Before you do this, spin the engine over several times with the starter to make sure it will spin free, and to bring the oil pressure up enough to pump up the lifters. Now, install the plugs, give it some fuel, and it should fire. If not then get some starting fluid and give it a shot or two of that, and it should fire. Keep the idle speed at a very minimum until it has warmed up some. It will smoke very bad, so you need it in a place where it won't choke you to death. This should work fine. Glad to help out, Good Luck!!!
15 is too young 36 is too old and 24 is just right 1,5,3,6,2,4 but thats for a 6 cylinder. When number 1 is fixing to power stoke number 5 is fixing to intake. If your use the same principles with the 8 cylinder you will find your ignition pattern. 1-8-7-5-6-4-2-3 thats what i found just now That and the number that has already been suggested Try that
The primer base of a rimfire cartridge is soft brass and the primer on a centerfire cartridge is very thin steel. Both act as a cushion to the firing pin when it hits. When a gun is dry fired - the firing pin does not stop on a soft cushion like it should. And it certainly is not stopping on air. Instead, it stops when it hits hard steel somewhere else along the pin. This can do several things - all bad. It can distort the pin internally and cause it to drag or hang up on the spring or wall. Since the pin and bolt are both made or hardened steel - evenually one is going to crack and shatter - usually the smaller firing pin. Some guns do not have an issue with dry firing - many do. Old revolvers with the firing pin sticking out the hammer - no problem. New revolvers and semi-autos with a transfer bar - no problem. Most all centerfire bolt action rifles - big, huge problem. Most match 22 bolt rifles can be easily damaged too. Usually the owners manual will specifically state if dry firing will cause damage or not. Always best to check the manual, or, call customer support if none is handy. When all else fails you can disassemble the gun and check the firing pin - if it hits the bolt when you press it, it is bad. If it bottoms out on a soft spring - you can probably dry fire it. Hope this helps
See my other response in chevrolet you will need fuel and fire. If the firing order is correct, you can double check with timing light. Light should blink when #1 plug fires. Point light at timing marks, it should blink about 10* before top dead center. Its common to get the firing order right, but the timing wrong. Engine needs correct firing order, and correct timing to run. Once you verify igntion system, check fuel. The light just went on in my head. Check to make sure you have power to distributor in key "start" position. If you don't have starter wired correctly, you won't have power to coil when key is in "start" position. You'll have power in "run" but not "start" to coil. The ign key cuts power to the normal coil wire in "start". Then the starter "S" terminal feeds power to the coil during cranking. Very common problem when putting a pontiac together.
check all your fuses, AND!, possibly the wires from the motor to the fuse box to make sure the wire insulation is still intact. Look up your fuse box order and numbers in your owners manual. It'll tell u which one is for your ac motor. my quess is its the fuse burnt out. since da old motor froze up.
