Hi there-we have been working on daughter's 1991 Dodge spirit-she slowed down for turn, went to accelerate, then no power-car began jerking, so she pulled over. Car would not start up again. Husband said car is getting fuel, but no spark. Replaced some relays, now the problem is that the crankshaft is turning, but the timing belt will not turn. Is this simply because the timing belt broke, or is there something else going on? I appreciate the help, and I hope my question made sense. Thank you so much.

Question: Crankshaft turns but timing belt does not

If the engine cranks the starter is spinning over the crankshaft and likely allowing fuel deliver form the pump because it sees the engine cranking. If the camshaft isn't turning the cam may be seized but is more likely teeth on the timing belt are stripped off.
Some 3.0L engine on Chrysler/Doge bend valves when the belt breaks, I don't believe the 2.5L engine does.

YES TIMING BELT SHOULD BE REPLACED EVERY 60.000 MILES .CHANCES ARE WHEN YOU REMOVE THE TIMING BELT COVERS YOU WILL FIND THE TEETH SHEARED AT THE CRANK END.THIS IS A NON-INTERFERENCE ENGINE WHICH MEANS YOU DON'T BEND VALVES WHEN THE BELT BREAKS.JUST LINE UP THE THREE TIMING MARKS ,INSTALL THE NEW BELT, PROPERLY TENSION THE BELT, REASSEMBLE AND DRIVE AWAY.GOOD LUCK GUNNY
