Guest twinbridge01 Posted August 6, 2006 Can anyone help!! I have finally finished wiring my 1991 205 gti up to a 1991 mi16 engine. I have used AndyRs guide and everything went straight forward enough. The engine will now turn over but I am not getting any power to the fuel pump. The fuel pump relay does not switch when the engine is turned over either. I thought this might be the problem so I fitted a new one but no joy. Does anyone have any suggestions??

Miles 331 1 Cars Posted August 6, 2006 Are you getting a switching signal to the relay when cranking? if not trace this back as it could be the Power feed or the signal from the ECU Share this post Link to post Share on other sites

I ll trace it back this weekend and see if im getting a 12v supply when cranking. Ill test it on the original side of the 205 loom. If this is ok I will swap the ecu with a spare to see if that cures it. Have you heard of anyone else having problems like this with the ECU?? Thanks for the info.

Thanks for the info. Chris I had this problem a while back - but check the crank sensor first, because if the ecu isn't getting a signal it won't know the engines turning and consequently wont energise the pump relay.
