Pinto Eec Iv Injection Wiring

[Guest MalcolmE]

I am trying to 'tidy up' the wiring on a recently acquired Robin Hood sub K with an injected 2 lt pinto engine. I have obviously done something wrong as I can't get it to start. The fuel pump runs continuously which I know is wrong, and there is no spark. The strange thing is that the wiring diagram in the Haynes manual doesn't tally with what I have on the car. The instrument cluster in the manual shows a 16 pin connector and mine only has 12. I have the coil etc wired as per diagram 4 in the 1987 to 1989 section except that there was a switched 12v connected to the green wire on the coil which is not shown on the diagram. When I started out the green wire was connected to coil negative when it seems to me it should go to positive. It worked though! Does anybody have a way of checking the TFI module which is a Motorcraft 86FB-12A297-AA (8M12B) and the EEC IV module which has the following numbers on the label. EFI-VM100 5BCA 85BB-12A650-CA. I am starting to suspect these components.

No I've been there and his drawings don't seem to tally with what I've got either!

Colin Ushers website is very useful but he refers to an 83BB ignition module and mine is an 85BB-12A650-CA. They appear to be different. I wish I knew what the module was supposed to do. He does explain the 12/16 pin anomaly on the instrument cluster though. Thanks for the link.

fuel pump running constantly means a sensor problem, it might not be seeing them all

Green wire should be on negative terminal of coil and goes to rev counter and TFI module. Coil positive has switched live black wire to positive terminal which also goes to TFI module.
