okay guys its been long time for me lol,
94 v6 camaro,
so far this were the symptoms before it quit on me.

While driving on the run at maybe 50-70 mph the camaro would jerk back and forth dropping my Rev gauge almost 1000 rpms, from running just fine to dropping rps without letting off gas pedal.
changed spark plug wires and it work fine.

Now,
few days later it wont start.
i thought it would be the starter because it would not crank the engine.
checked starter got it tested its fine. checked flywheel teeth while starter was off and they look in good condition.

bottom line is my starter is good i got juice from my battery, but still the engine is not turning. some help please!!!
thought about my timing chain? but don't know

 

sounds like brain freeze... j/k... if its not turning over at all, sounds like a bad problem. your started works till it is installed?

 

Was/is there oil in it?

 

Are your battery cables good -- is the starter turning over when you turn the key? Have any codes on the computer -- have it scanned... Have you had the fuel system checked -- is there adequate pressure?

 

mm i'd have to check to see if there is any oil ! lol mm starter worked before and after install! yes when i turn the key starter works. what would the fuel system do if i dont have adaqute fuel pressure. the engine is not cranking at all. i've heard how the starter sounds when it is spinning with out engaging with the flywheel, but different like if its engaging with the fly wheel.

 

How is your spark at each coil pack terminal? You can check this with some darkness and a screwdriver...

 

I think you misread the original statement. He says the engine won't physically turn over. He said the starter tested out fine, and sounds like it is engaging. This would lead one to believe that the rotating assembly is now one with the block.

 

You need to put a breaker bar on the front pulley and see if the motor will turn. If it will not it really does not mater why, the motor is shot.

 

that was my idea to try to manually turn the engine. i'll get back at you guys thanks. turn the engine with out the belt on, right?

 

That would be easier.
