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?

 

It might be the fuel pump, check and see if you hear it prime...

 

LOL, how long were you running your car off of carb cleaner?

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.

Check this first, and don't run the engine with ether or carb cleaner.

 

my car will run fine but when i turn it off for a while then try and turn it back on it wont start...i dont no why. so i just open the gas cap and let the pressure out and then itll turn on fine...wierd as hell but it works all the time!!

 

Pressure is comin back out the pump instead of thru the lines? mebe u got a goofy pump or bad one. im not sayin i know this but if u think about it. its a possibility
