    That's an oil pressure switch.
    If it's a Digifant engine, there should be 2 temp switches on the water pipe flange housing on the front of the engine. On early cars I think it's alloy, black plastic on later ones .

    2 wires connection plug on it?
    any of you lads from co durham ?would like some one to cast an eye over it
     
  14. jeffcatr New Member

    the one on housing on front of engine has 2 sensors the one iv change had white plastic connection2 pins,the other single connection. what about throttle body switches ?
     
  15. Spacecowboy Paid Member Paid Member

    You have an early 8v digifant like me. The white 2 pin sensor is the ecu sensor (its blue on the later Digifant with the plastic coolant flange).

    If you want to check the microswitches on the throttle body follow rubjonny guide in stickies. Be worth checking the FPR too however are you certain the ecu checks out? A fried ecu is famous for overfueling on these engines...

    well a bought new ecu but may of gone so im doing to get it checked the fuel pressure reg is a new one to .
     
  17. jeffcatr New Member

    Bad earths can fry the ecu. Best to make doubly sure all the earths are good e.g. battery to chassis leg to gearbox, head to coil and there is one more I think which someone will be along shortly to advise.

    I don't think you will be able to view rjs guide if you are not a full paid member. It's in the Engine FAQ section. Worth a tenner just for the guide (its basically how to tune and keep sweet the 8v digifant).

    thank you for the advice going to check earths again ,a was wondering should there be an earth from inlet manifold,
