My old honda runs great…so great that I do not want to get rid of it but……when it gets rained on and /or the weather is especially humid IT WON’T START…..installed a new main relay and no difference…..I have had the yellow service light on for many years and when I try to start the car the various red lights and this yellow light come on as always..then the red lights go out and there is nothing….but then sometimes I hear a hum of (I think ) the fuel pump coming on and then it will start! Runs great ….but as electrical problems are hard to diagnose….is it time to cut my losses and get a new car? HELP…advice greatly appreciated!!
