Q: Car cranks, but won't turn over

asked by on

My 2004 impala won't start. It cranks but it won't turn over. I've tried a number of different things to try and resolve the issue, but none of it seems to work.

My car has 150000 miles.
My car has an automatic transmission.

There is a number of tests that would need to be done on this vehicle to narrow the problem down to an ignition, computer or fuel system problem. Have a mechanic like one from YourMechanic come and test the computer sensors, fuel pressure from fuel pump and spark signal from the crank and cam sensors.
