Help Code 11 on 91Q

[crix20001]

I tried using the search to figure out this problem with no succes im the second owner of a dealer serviced Q 125000 miles on engine 60000 on transmission dealer replaced recently changed one bad injector on intake side new fuel pump and repaired fuel pump ecu. Came home form work one day parked up car never started up again but now i checked the ecu it shows code 11. Got a new camshaft angle sensor changed it same thing just tumbles endlessly any ideas??

Or camshaft position sensor which ever one is more politically correct one of my friends told me i should look into replacing the ecu also ecu thats in the car currently says infiniti remanufactured but maintainance history shows no such swapping of ecu done to the car

Fuel pump ECU = FPCU?

Why do you suspect the ECU? 1991 had the transmissions replaced under a silent recall. Perhaps Infiniti replaced the TCU also? Check to see if your transmission drain pan has a bolt.

Many ECUs available for the early models. I guess it is fair to presume it was exchanged if upgraded.

What do your "friends" say about timing chain guides?

[elwesso]

the code is probably coming from a corroded connector or some sort of connection issue.

I. Suspected the ecu because the. Injectors are staying open indifinately and the fuel pump clicks on when it wants to

I checked conections to the camshaft sensor all seemed fine
