Compression at zero
 

Just recently i was driving my car and parked her for the night, woke up in tthe morning went to go start it and wouldnt start. Thought it was just flooded but was wrong. I did a compression check and theres no compression. I checked for spark ive got spark, so ive concluded to being the starter. What else could it be if its not the starter?

Car is a 86 n/a.

HOw did you do a compression test if your starter is bad?

Thats my point i had no compression.

did u test it?

Im confused...did you actually do a compression check with a testing gauge??? You should know if your starter is working...it spins the motor.

Maybe your battery is just low

Yes i tried a compression check and tester read 0 like i said.

Wow....
Seriously, how could you do any of those tests if the starter is bad? The motor has to turn to do a compression test and the motor has to turn to test for spark. Well, I guess you could turn it by hand, but still. All that aside, there is no possible way that a bad starter could cause the engine to have no compression. It can cause it to read no compression because it isn't turning the engine, but I really hope that isn't your problem because no one can help you if you do a compression test and think that it was 0 compression when the starter motor isn't even turning.

That said, if it actually has 0 PSI compression, then you have a blown motor and you will have to rebuild it. That is the only fix for 0 compression. And before you ask, it cost a minimum of around 600 bucks to fix it yourself, and that is if you are very lucky. More than likely it will run more like 1500. Add on 500+ to have someone else to it.

I am confused also, what exactly did you do for a compression check?

I did a compression check cause i was checking for spark and while i was doing that thought it would just check for the hell of it.

Take the top plugs out, put about small amount of tranny fluid in holes. Reinstall plugs. Remove fuel pump relay fuse, turn engine over about 10 to 15 revolutions. put the fuse back in, attempt to start the car. THERE WILL BE SMOKE for about 45 seconds if it will fire, and you BETTER have a good battery and starter for this one.

P.S may take a few times for the car to start, if it sounds like it wants to start but doesnt the first few times... thats good!

Dude, what we are asking is if, the starter is bad and the engine won't turn, then how did you run a compression test, which requires the engine to turn?

Or is the starter not actually bad and you were just guessing or something?

A badly flooded rotary can act like it has no compression because, well, that's what flooding in a rotary is, temporary loss of compression due to gas having washed the oil film off the walls. IT's almost impossible to have zero compression on both chambers at once, so if your gauge is showing this then you are likely just suffering from a severe flood. I have instructions on my website as to how to clear this. www.rotaryresurrection.com under tech.
