Now,check for voltage at the Fuel Sender.
Does the pump run when key is turned to on position?..should run for 2 secs ...
If no voltage is present,you need to check the circuit.
Check all Fuses
Check Fuel pump Relay
Check all related wiring
If voltage is present,connect a Fuel Pressure Gauge and test fuel pressure..should be betwen 41 - 47 psi
If you have spark and proper pressure,make sure you have compression..
Check for injector pulse using a noid light
