Ford bantam 1.3 rocam no signal on crank & cam sensor

Check the relays and fuses. If the starter selonoid cable is running in the same channel as the crank angle sensor signal wires, remove the Selnoid wire out of that channel and away from the sensor wires. Check the amperage draw on the main starter cable from the battery Pos cable to the starter and clean the terminals. Clean and check the earth cable from the Battery Neg to the body and fit an extra cable from the battery Neg cable from the gearbox.
