Do you have normal compression, spark, and fuel pressure ?
Will it try to start if you spray starting fluid into the throttle body ?

SOURCE: 1995 cadillac deville "won't start"

When you disconnect a spark plug wire, do you get spark when you crank the engine over?
If so,
When you turn the key to the "run" position (do not crank) do you here the fuel pump run for 2 - 3 seconds?
Let me know.
Regards,

SOURCE: engine miss,replaced fuel

Do a compression test and make sure it is not a mechanical problem.Could be burnt valve,bad cam,or broken valve spring.If you know which cylinder is missing pull the valve cover and check the valves and see if they are all moving up and down evenly when you turn the motor over.Just disable the vehicle from starting or you can do it with it running.Hope this helps.Good luck.

I see that you replaced battery, coil, plugs, wires, cap and rotor. Did you or do you have a check engine light or SES light on? If you did not I agree with the problem being Anti theft which includes a replacement key not having a transponder chip. BUT at the same time it could be something as simple as dirty battery post or bad battery cables, since sometimes it does start. I RECOMMEND CHECKING THE BATTERY CABLES FIRST. let me know if this works for you.

Check the plug wire from the ignition coil to the distributor cap.
If you haven't already, replace the distributor cap and rotor.
The GM Vortec's have issues with moisture getting inside the cap and rotor and causing problems.

Hi, Hope I can help you.
I do not know how you have checked for spark, but lets start from the beginning.
Lets start with an ignition systems check.
1. I want you to remove the high voltage coil wire. ( That's the wire in the center of the distributor cap.) Using a good pair of insulated pliers. I want you to hold it about 1/4 inch from a good engine ground. Now you will need a bit of help from a partner. Get them to turn the key and crank the engine. You should see a bright blue and well defined spark. Ok, If you have spark I want you to slowly move the coil wire away from the engine ground. As you do this I want you to pay attention to the coil tower. (The coil tower is where the other end of the coil wire is attached.) What your looking for is arcing and sparking at the coil tower. If this happens then you need to replace the coil with a new one. If this does not happen then your coil is working fine, and we will have to move on.
Note if you do not get spark from the coil wire replace the coil.

2. Ok if you have spark now we have find out if the spark is making it to the spark plugs. How are we going to do this? By checking the rotor, distributor cap, spark plug wires and spark plugs.First lets remove the distributor cap. This will allow use to inspected the rotor and the distributor cap. What your looking for is, cracks, carbon tracks and wear at the tip of the rotor. On the distributor ,look inside the cap for cracks, carbon tracks and wear on the terminals. If you find any of this replace the distributor cap and rotor. ( Note if you have any doubt of the condition of the rotor or the cap replace them.) Next lets check your spark plug wires. Lets pull off one of the spark plug wires from the spark plug side. Now inspect the wire connection for a white crusty powder. If you find crust replace your wires. Now you should check all of them the same way, but if even one has corrosion replace them all. You are going to have to inspect the wire its self . Going down the whole length of the wire. Holes cracks burn Marks and other damage. Once again if you find any damage replace them all.
I hope this will help you and good luck to all the read this FixYa

1991 JEEP WRANGLER WONT START


Take the distributor cap have someone crank the car and look if rotor turns, look at rotor conditions, I am sure that you have replaced it, hot wire from positive on the battery to positive on the coil, if car starts after you have a problem on the key, Is it fuel getting to the injectors? after You replaced so many things,if your rotor is not turning when You crank the engine, your timing chain must be defective or timing gear,
