Hey guys, I need some help

I bought a 99 DX Automatic and the engine is having some problems. It will turn over but while it is turning over it makes a high pitched screeching, and it feels like the engine is spinning very slow. It almost feels like something is binding. The screeching is coming from the starter/ transmission side.

I tried the starter off my known working 2000 civic and it makes the same noise, so it is not the starter, I even tried a new battery with proper amps and it has the same symptoms. I also measured the voltage while cranking it is at a reasonable number.

I took all the plugs off to remove all compression, same issue. I tested all pistons are moving up and down, the timing belt is intact. I can spin the engine by hand with a ratchet on the crank pulley, I haven't taken the accessory belts off, but the engine spins without much effort.

I am running out of ideas. The transmission rolled freely when it was in gear so I don't think it is anything in the transmission binding.

Any ideas? Can something have seized like a bearing that will put too much force on the starter? I figured if there is too much resistance on the starter I should feel it by hand.

Thanks

 

Try cleaning and tightening the G1 battery and G3 transmission ground connections.

 

Found the issue.

I thought I had loosened the alternator completely but I did not, I took the alternator belt off and the engine spins freely now, the alternator is completely seized.

Problem now is I am getting no spark.

I checked all the grounds, I pulled the distributor and checked the ignition coil, all the ohms read within spec.

I am not getting spark on any cylinder. I do get fuel and the pump is priming.

 

Do u have power to the coil?

 

nope, I am slowly tracing everything back.

 

Generally if you dont have power to the coil its a Bad ignition switch.. U say its turning over tho correct? Does the main relay "click" when u turn the key over?

 

Check fuse 9.

 

So I have power at the ignition coil/distributor plug I also have an ignition signal.
Could it be a bad ignition coil?
Fuses were all checked and are good
Checked the main relay its sending a signal, its getting an ignition signal at the key.

It seems to be an issue in the distributor.

 

Does the fuel pump prime?

Any CEL codes?

 

So I am getting a signal from the ECM for ignition, but no signal out to the ignition coil, according to troubleshoot my car it is the ignition control module.

 

Yep, u have it narrowed Down to the icm since the coil checks out

 

Car is running!

Ended up being the ignition coil, I tested it incorrectly the first time there was a signal coming from the ICM, I took a known working ignition coil and the car fired right up.

Thanks for the help.
