    Default DTA EMS Fuel Pump Issue

    Hi Guys,

    As some of you know, I've recently picked up an HPC Cat with a Vauxhaul 2.0 and DTA EMS. I had a freind help me sort my stripped gearbox plug by welding on another piece of metal which permitted the plug removal. Now. The mechanic who did the work is very knowledgeable and disconnected the battery to ensure no shortages as a result of the welding. As a result and unbeknowenst to me, this could have affected the DTA system and fuel pump as the fuel pump no longer pressurizes the engine for starting. When I bought the car I was told to turn the ignition kep a few times until the ticking of the fuel pump slowed and then I could crank the ignition all the way. Since I've reconnected the battery, the fuel pump keeps ticking and does not slow at all so the car is very difficult to start. Usually takes 10 tries now. So, my qyestion is, what can I do to reset the fuel pump so that it does it's job and pressurizes properly so I can start the car without issue?

    As always, thanks in advance,

    I have a DTA ECU on my Yellow seven. When I turn the key to the on position the pump primes and then stops. I too usually wait for the pump to stop before turning the key to the cranking position to start the car.

    When I assembled my car originally, I had to install a relay between the ECU and the Pump. If you have a relay in there check to see if it's connected or working properly. Tom

    I installed mine on the bulkhead right above the ECU.

    If you know the part number, you may find a picture online for identification.
