timing belt was replaced on 12/29/2006 got the slip for it. around that same time the water pump was replaced as well...

crank sensor???

The crank sensor sends a signal to the omputer to let it knw where it is on timing. Tach. But usually if its bad it wont start at all, or they start going bad after its hot....like you'll be driving, stop at the store, come back out and it wont start for 30 minutes, then it will start.

So now we're back to MAF, Coolant temp, or ignition (plugs, wires, coil)
