my girl drove the crx and she call me telling me its dead...i went to pick her up and check it out. so when i got there i just add gas in there thinking its out of gas, but it wasnt IT DID NOT START!

it doesnt turn over..just a long erhhhhhhhhh sound, thats it. i took the timing belt cover off and when try to start it..the belt shake and i hear the crankshaft spining, and the camshaft jerk a lil bit. also the belt is loose.

the car is 90 si, 188k miles, i changed the sparks, themostat and got new battery for it a month ago. the alternator is good because when i got a new battery i unhook the battery to see if it still run, and it does.

what could it be? some people suggest its the belt, just want some more imput. THANKS!!
