Default 1976 eldog

I have a 1976 eldorado conv, I was hoping someone can direct me to the location of the fuel injection relay. I can't get the car to start, if I pour gas directly into the throut it starts but will not stay on by itself. I checked for fuel pressure at the rail and there is plenty so I am assuming that the injector relay is bad and not letting them do there job. Any sugestion will be highly appreciated. Thank You

EFI is somewhat of a pain. Do you have or access to FSM? If you have "Noid light" see if it blinks as engine is cranked (all 8 ). If you don't check to see if you have 12v to injector connectors. There is a sensor (trigger points) mounts to distributor which sends signal to control module to operate injectors. EFI is a unique type of F.I. there are isn't a scanner or codes, there was a test box long since discontinued(it was very helpful, but did not always take you to the solution). You really need a factory service manual if you don't have one. EFI was on 74-80 Eldo,76-80 Seville, 77-80 Fleetwoods. The basic diagnosis for EFI is the same regardless of engine size.

If you have a picture or schematics for this vehicle I would really appreciated. I have bought a noid light kit to test the injectors but I'm 100% sure I have no elect to the injectors. Thank you

Actually,there are very rare chance to owned hundred percent none faulty Vintage,so these type of issue are in the Vintage but who love his car also take it with care and in a mint condition.I am a mechanic by profession and know well about the car,i owned two Vintages in a fully perfect condition.
