i was up in prescott over the weekend and it was much colder there and it did the same thing. it starts fine when its warmer out.seems as if it only does it when its cold. should i start at the relay first?
Yes. It is the easiest and least expensive step. Plus, it solved the same exact symptoms for many of the members trucks here including mine last winter. Xcept, I replaced the glow plugs first. Oh well, Live and learn. If I knew about this forum last winter I would have been much better off.
Depending on what computer code your truck has, the wait to start light will go out, you'll start it, and the glow plugs will continue to cycle for up to 1 1/2 minutes. On the really cold mornings, 20 deg or so, I'll turn the key to start the glow plugs, give them 20 seconds, turn the key off, then back on to start the truck. The 20 seconds will warm the combustion chamber slightly, and by turning the key off and then back on, I allow them to cycle for the full amount of time. I don't bother with the extra 20 seconds when it's 40 deg outside.
so if im having to do this more than twice to start it on a chilly morning, could it be that my relay is bad? i picked up a #MR99 relay at autozone this am --anyone know if it will work?
I have replaced the glow plugs with autolite (they are only half the length of the original glow plugs but they thread right in), the glow plug relay, the starter (after the old one burnt up) and one battery. The other battery was replaced before I took possession of the truck when I bought it almost a year ago and it tests out ok. Turns over fast now. But when the temp drops, if I don't have it plugged in, it is still a bear to start. Have to cycle the glow plugs many times before attempting to start. It wasn't hard to start last winter after I bought it and the temps dropped to the teens (didn't even have to plug it in then). I have laid off trying to work on the problem lately. I just carry an extension cord with me everywhere I go. It hasn't failed to start when plugged in, starts right up. But to take any trips in the winter requires some preplanning on where to park where there is a receptacle to plug in to. Suggestions anyone?
