So I have an 03 fatboy that after it runs for awhile shuts down. I’m getting a code that the front fuel injector is lean and the main relay is open or closed. I’ve replaced all the lines in the tank, fuel filter and pressure regulator , fuel pump and the disconnect. I’ve also replaced the tps and main relay. I’m tired of dumping money into it. This started happening after I changed my tank and rear fender. I’ve also checked my grounds after I did that and cleaned all of them and still no better.
