Ok guys, my truck now won't strt, I had soem water problems and rust problems, but i never ran it with the watre light on, I got it all cleaned out and had it runnin good, but when i kille dit last, it won't crank back up. No trouble lights are on, but when I do the key on off thing it gives me P2269, the water code, so i drained my water trap twice and still no start and still the code is, I have disconected my smoke switch, plugged the dummy plug in where my chip goes to make sure it stock, changed the fuel filter, my fuel pressure dummy goes off when i turn the key on so I have plenty of fuel at the injector pump. I have checked all the see through fuses, but donno how to check the realays. Any help appreciated. Sam
