Make sure battery is fully charged. Connect a test light to battery ground and touch batt+ to check if light. Now test that there is power to the starter heavy wire directly connected to the starter. If power, good. Now test for cranking power to solenoid wire which is on top of starter; have someone cranks as you check for power. If there is power, starter could be acting up. If not, check all fuses and neutral switch. Be careful working around moving and hot parts.

When you turn the ignition on the pump is energized for 2 to 3 seconds. did you check it like that. it is also energized when cranking the engine. there is a fuse then a relay then the fuel pump. the relay is ran/ energized by the ecm computer. if there is a fuse relay box under the hood you'll need to check there to. good luck
