hello can anyone help? I disconnected the battery in my Freelander 1 2l diesel to do some welding work. When I reconnected the car won't start. The heater coil doesn't come up on the dash when ignition is turned on. Could not hear power going to the diesel pump. Changed the ECU the car will turn over but cuts out after approx 10 secs and I can hear power to the diesel pump. I bought a Landrover Terrafirma model no TF930 but this will not read the ECU. The battery is fully charged. I have read some threads on here and tried some of the suggestions but to no avail. I have cleaned all the terminals and all are good. I have checked fuses and relays and all seem in good order. Can anybody offer anymore advice?
