check you crank position sensor, if resistance is not between 350-600 ohms, you have a defective sensor. Mostly will be your problem or check coil, primary coil resistance should be .63-.77 ohms and secondary resistance should be 12,800-19,200 ohms. Check all sensors in distributor, TDC/CKP/CYP. they all must be working for the ecu to inject fuel.
