      Ok so I’m stuck…My truck won’t start. I thought it was the fuel pump, but no. Its getting fire but nothing more. I’ve changed battery, starter, crankshaft,camshaft & throttle body position sensors, relay, tumbler, fuel pump motor and fuel filter..nothing
      I changed the ignition, but ended up putting ok one back in…you think it’s something with the anti theft system(relearn)?
