Maybe blown apex seal?
 

Ok heres what happend. I Rebuilt my 89 n'a 13b about 3 months ago. since then i put 3,000 miles on it and properly broke it in. I did a compression test 3 weeks ago and got 130psi on both rotors. (equal pulses on all rotor faces). I parked my car last wendsday because my boss sent me to school and gave me a loaner car. I came back mon for the day and ran the car. it started right up. After about 2 minutes it started running normal. I shut off the car and left cause i was due back to school. when i returend back from school yeasterday i ran into problems. It took about 30 seconds to get it running (probably because i turned it off with out it worming it up fullly, had to unflood). after it was running i had to hold the gas to keep it running. after about 2 minutes i let my foot off, the engine holted to a stop real quick. i tried to restart but i would not. the starter would crank but it sounded like it would only crank 2 teeth at a time. thinking i burned up the starter i replaced it . but the second one did the same thing. the engine has a shitty sound. The pluges where not wet. i thing i washed all the oil away and when i started it, it blew an apex seal due to no oil. any segestions Im Broke and need this car. if this engine is blown in screwed. if any one can help they will save my thanksgiving. Thanks

if im correct if the car starts you didnt blow an apex cause if one apex went out the other 2 went along with it.... has to be something else just go over the car and check it out..

i know this car in and out i bought it out of a junk yard and had poublems with about everything so far. this engine is not cranking and its now due to a stater. the sarted can barly spin the bitch.

has this ever happend to any 1 else

since you started it and then shut it rught off last time, I would say that a chunk of carbon is probably stuck between a seal and housing.
Try to spin the engine the other way and work it loose, when it spins, do a compression check to see if it damaged anything

What you should do, is get some ATF (automatic tranny fluid), then take off your upper manifold....and pour 2 capfulls down each hole, then put it back on, and turn it by hand for awhile. the atf can work wonders for carbon lock....or stuck apex seals. Good luck with that.

can i put the atf in the spark plug holes and why would i have a carbon build up with such a young motor? how long should the fluid sit in the rotors?

CHange your plugs, and check your plugwires.
