clicking come from d/s front area? If so, thats the ABS system kick'n in. Wait for 45sec-1min, prior to firing up. If you have the GPR-LED mod, you'd see that the actual gp relay stays on WAY LONGER than the dummy WTS light goes off. meaning, ur try'n to start ur truck in cold temps, with 11v. instead of the 12.5-ish volts.
Have you unplugged the UVCH and ohmed outthe gp's?
