not running

hopefully someone can help...i have 92 mazda b2200 i was driving and it just stopped then would start up and and go as long as i didnt let off gas....put new carb,plugs,wires,control module...took distributor and coil out and put in friends 2200 and started fine....now all it does is crank but wont turn over....i got fuel pressure and i got spark...im at a lose...any help would be appreciated...one other thing crankshaft pulley was loose so wobbled a little bit...

Checked cap and rotor? Fuel filter could possibly be plugged....? Vaccum leaks?....

had put distributor cap rotor and coil in a friends b2200 and it started right up...also have good fuel flow...even if i put engine start in carb will not crank over....

sounds like a timing issue or the cats plugged up u say the crank pulley was loose?? might want to check and see if it slipped on the woodruff key

im gonna chk all the timing today and at the same time ill check the woodruf key thanks again ill post again if it works or not..

check for broken teeth on the timing belt
