need more info... did you mess with anything? have you just dropped a motor? whats up? but check all of your grounds. Why would you put a spark plug near a ground? that doesn't even make sense, but making sure all of your grounds are connected would be a great place to start.

I put it next to some that is bare to check for spark!!! click my name and check out my other forum theres plenty of info (anger and frustration). Also Now I am getting spark but it still wont start, and yes fuel also, and it does turn over.I am so desperate that I am about to try and push and jump start it. Ill be back soon with the answer, it didn't start.

I have replaced distributor rotor,cap, maf, ignition coil,fuel filter and plug wires. I checked spark on coil its good, checked for spark on spark plug and its also good.

Got any ideas!?

You have fuel, you have spark. Is the spark strong enough and is the fuel being delivered? The spark you observe needs to be a strong blue spark. It should be able to jump a distance of at least a 1/4 inch or so.

For fuel, I'm assuming you checked the line and not at the injectors. You now need to verify that the injectors are pulsing. Either disconnect the injectors and put a noid light (bulb that plugs in injector clip) in and see if they get power or remove the fuel rail and either crank the engine or spin the distributor to see if they are squirting fuel.

If all that checks out ok I would go back to my original guess that your timing is out. Either at the distributor when you messed with it (sounds like you are 180degrees out of time and its sparking on exhaust stroke) or your timing chain jumped time. If it's the latter, you'll need to basically replace the timing chain and its components.

I think you're just out of time completely. You said you replaced the distro and cap but never mentioned if you checked your timing to make sure it's on.

Well this post was just to get a quick answer . If you check out my other forum you will see my timing is PERFECT!! Also I am getting spark from plugs from coil as well. I felt my fuel line and and I am getting fuel. I have to be getting fuel to the injectors because when I try to start my car a couple times it will flood (only in one cylinder though).
