Hi, Hope some one can help shed a little light on this problem. I am getting no power at my fuel pump. Fuses are fine (1 in dash and one under the drivers seat.) On the relay i am getting battery voltage on brown/green 30 wire with ignition on. no power from either white/purple 87 to pump (via inertia switch which tests ok) or white and orange 87a to L and R lambda sensors. Pins 86 white/grey (connects to pin 19 on ECU and +bat via dash fuse c4) has 12v and pin 85 blue/purple (to pin 16 on ecu) also seems to have 12v. It seems to me that pin 85 should ground thru ecu to energise relay but as I say seems to be sitting at 12 v and thus not energising the relay. Any idea why (apart from dead ecu)? Is it just replacable with a normal relay? Swopped relay with same type silver capped relay under chair so reasonably sure relay is ok.
As a byword, it also has an LPG system which will run great if I apply power manually to the pump and start up then switch to gas. Where is the usual place for LPG installer to switch off petrol pump when on gas?
Any input appreciated and I am at headscratching phase!!!!
