This is my first cold season with my pickup and I'm having some issues...its a 96 F250, 130k miles, runs great when warm but I have to cycle my key 3 times to get it to start and its only about 30 degrees F outside. I have ohm'd all my glow plugs, the one on the right rear was bad so I changed it. All the others tested out @ .9-1.3 ohms. My relay looks brand new (I've only had truck since May) I took the two large wires off anyway and wirebrushed them & re-installed. Any ideas? My wait to start light stays on about 5-6 seconds in the mornings, is this normal? Should it be longer? Anything else I can test? Strange thing is when it does start it starts real quick and smooths out instantly, no missing or abundant amount of smoke. Any ideas would be greatly appreciated, I live in northern MN and I know its gonna be a whole lot colder very shortly.
