2000 Hard starting when cool or cold.
Hi all. Looks like a great board here.
Anyway, I have a 2000 7.3L in an F-650. Now, this is an International build but I think everything to do with the engine itself are the same. I have read and searched the forums and done all the suggested tests. The test light on the glow plugs checks out ok. I tested the glow plug relay, it's new and good. I tested for voltage at the harness connector on all eight pins for the glow plugs. That checks out. This thing is still hard starting a lot of the time and it's parked inside a heated shop. When it's been running it starts easy.
Started somewhat easy today but there have been times we've had to use ether to get it going (I know, that's not the best idea).
The only thing that stands out to me is that the GP relay doesn't cut-off voltage when the 'wait to start' light goes out on the dash. Not sure if this indicates a problem or if it's normal.
Anyone have any tips on what might be wrong here?
Thanks ahead of time.
