Has the inertia switch located by the driivers side kick panel been reset and checked for continuity??? Has the fuel filter been changed???
Does the engine run when using starting fluid???
Were you driving when engine just died???
Do you ever have to add coolant to the system?? (WOndering if the water pump is leaking and has ruined the timing belt)
Did they do a fuel pressure test with a fuel pressure tester before replacing fuel pump or just change fuel pump?? Has the fuel pressure regulator been checked???
