Question about Cars & Trucks
Replaced Fuel Pump, Cap & Rotor, New Wires, New Plugs, New Fuel Relay Switch still does not start.
Well Dave you just can't replace parts an hope you fix it ! There are test that need to be done to find out what system is malfunctioning ! If no spark , the ignition system is at fault ! An that could be any one of a number of things , ignition control module , engine computer ,crankshaft position sensor. If the fuel system is at fault is there battery voltage getting to the fuel pump through the relay , is the PCM turning on the relay ? The relay is most often a four pin relay an where it plugs into the fuse / relay box you can test for power an ground an control of the circuit ! Another possibility would be the anti-theft system not letting it start, any light like SECURITY lit on the dash ? Rather then just replacing parts Dave in a random fashion ,you need to find out what is missing fuel , spark an is the engine in good mechanical condition an no SECURITY light ! good luck Dave !
You spent more on parts then it would have cost to take to a repair shop !
