OKAY i have a 1990 acura intregra ls and sometime it has trouble starting.. i dont know if its the fuel pump or fuel filter.. sometime it just starts great then sometime i have to spray carb cleaner in the intake manofold then it would start as long as the carb cleaner is left in there..? i have put in carb and injection cleaner but that doesnt help.. is my fuel filter clogged or something not sure.. ani suggestion on what i should do?

This is more than likely your main relay flaking out and not telling the fuel pump to turn on. Listen for the priming of the pump (low hum) or click (same time the dummy lights finish their self check) of the relay opening the circuit.

where is the main relay on my car? ani suggestion on what i should do?

He said it WILL start if he sprays carb cleaner in the intake. How the hell do you get no spark out of that?

Sounds like a fuel pressure problem... First thing I would do is replace the filter.

 

this is really funny because i have the same car, that had the same problem, that i fixed the same way for a time (yay aerosols!!!!!!)
It turned out with me that there was a component in the ECU that controls the starting functions of the car and only those functions, and it had decided to take a crap on me. I had a vw shop replace it with one out of a vw bug and it has started great for almost a year now. sorry about being vague but it may be worth it to have your ECU checked out.
