Why does everyone go to a fuel pump without verifying things.
You'll need to pull the lower dash cover off, both the plastic one and the metal shroud underneath. You will need a 7mm and an 8mm socket and short extension or a nutdriver tool for each. Check the Ignition switch harness.
Constant 12V+ Yellow Ignition Switch Harness
Starter Red/Light Blue Ignition Switch Harness
Ignition Red/Light Green Ignition Switch Harness
Accessory Gray/Yellow Ignition Switch Harness
check the wires. You should have two Gray/Yellow When the vehicle is in the KO/EO position, all should show 12.4 volts on the DVOM or red light on a test light. The starter wire obviously should only show voltage (12v) while cranking.
