08 chevy malibu
So I went to work the car started up fine and ran like normal
got to work and was there dfor maybe an hour and I went
out to go the the bank and it wouldnt start had to have it
towed home we checked the battery,cables, wires, fuel
pump, starter, alternator, changed the crank shaft sensors
checked the ecm and all are good its got spark and its got
fuel but it won't completely turn over it struggles and
