Hi
Thanks for the reply. Testing with just ignition on at the 2 wire plug coolant sensor br/gr wire, and brown wire on the maf sensor which incorporates the air temp sensor, I am getting 9.6 volts on the meter (car battery getting low with testing). The connecting test bulb 21w to battery neg and then to the above wire`s, bulb does not light. is this loosing the feed somewhere.

Would i need to unplug the injectors to do the cranking test, As i have the front & centre plenoms and various connections off, to gain access, And to stop unwanted petrol being injected into engine.
