    1988 Nissan Pickup The break light, but was always on. Well, I just swapped out an engine from another vehicle that ran. the engine started up and ran and sounded good, but it was getting late and to dark to continue. So we came back in the morning and finished up rapping up the job. but we found that the intake man gasket was put in wrong so we re-did it and went to try starting it and nothing happens other than running the battery down. I re-checked all the hoses and electric plugins over more than once., swapped computer brains and electronic control relay thing, also swapped solenoids, I don’t’ spell good still nothing.

    The book I’m using is the Haynes, but it don’t deal with much of 1988s, it deals with mainly 1980s thur 1985s. Well, after swapping over a new used motor. I found that the carb is acting like its not getting any gas. The fuel pump is working gas gets to the carb, but doesn’t give the gas to the motor. If you put gas in the jets area it kicks and tries to start, and sounds good until the gas gets used up, and then it died again. Well for one thing, I’m think it may have to do with the electronic control gizmo, not sure about the carbs air hoses or where the gas feed line goes to on the carb, my buddy seems to think the line from the top of the fuel filter goes to the feed intake by the lefthand side of the engine, and the vapor feed is the second line that comes from the gas tank. well I working with the Haynes book. it doesnt’ show the exploded view of the engine of this vehicle.

    Stick with the fuel injection if you can. Easy hookup and runs better. As far as your carb problem, it definitely sounds like you have an internal problem with the carburetor. If you can put gas down it and it starts and runs ok until the gas is gone, you aren’t getting gas through the carb for the truck to run on. Maybe try switching carbs from another truck.
