I have a 2003 truck, which after much work is great, and starts fine.... until it doesnt want to crank over!
Ignition is fine, starter motor is fine, only relay i can find for the starter is in the engine bay and been cleaned up, so is the earth terminals near the relay and fuse box!
Any ideas or wiring diagrams to trace this fault will be greatfully recieved. TIA

maybe of some use Online Classic Wiring Diagrams

Traced what i could, still the same😤 have decided to fit a supplementary relay connecting in parallel to the starter with a push button in the cab, so if the correct (key) wont start it at least i can bypass it in the dry!

Anybody else had this issue or know of any solutions??
