Fuel solenoid keeps cutting out is it a faulty relay?

Hi been looking at wiring diagrams for this one i assume the vehicle does not have an alarm or immobiliser the wiring diagram shows no relays for the solenoid its a direct power supply from the ignition switch so you have either got a faulty ignition switch or wiring from switch to solenoid if it has got and alarm or immobiliser it could be a fault with them
