Ive got a 1994 2.8L diesel Toyota Hilux dual cab. Wont start in the mornings or evening if cold. Got 280k on the clock. When you turn the ignition key there is nothing. Lights on the dash display and glow plug light comes on. Can clutch start the car. Once the car is running for a while and warms up, you can turn it off and it will ignition start every time. The battery, glow plugs and ignition barrel have all been replaced. Any ideas would be greatly appreciated.
