I have been having problems with my maf sensor not reading continuously. While i was tracing wire i found where my fingerstick was tapped in had be come a little loose so i removed the fingerstick and put everything back to stock. I fired up truck and was starting to check the voltages coming to and from maf sensor when all off a sudden my truck died. And now will not crank. No CEL. No blown fuses. Batteries tested good. Everything else works. Does anyone have any ideas?
