Start and Idle problem
p1) When I go to start my e99 7.3 it takes a few cranks (sometimes a few tries) to start, even if you let it glow long past the WTS light.
p2) When it does start, at idle it surges, as in it revs between 700-1500 rpm, and when it gets to 1500 rpm, it makes a whine, (which I can only relate to a PS pump when it is completely maxed out to one side at a low rpm) then goes back down to 700 and starts all over again. If you rev the motor up and then let off, it temporarily goes away and then comes back in a minute or so.
I have put some anti gel in the tank, and have a new fuel filter yet to install (when I get time). I'm thinking maybe a vaccum leak? possibly bad glow plugs/ relay/fuse? I haven't had a chance to plug it in and try heating it first to see if that helps with the starting, gonna try and do it tommorrow, as I am not currently driving the truck (not registered yet).
Would the WTS light still come on if the glow plug relay is bad?
I figure that people who know these motors better than me should have some ideas of what to look out for .
What are you guys thinking, I'm looking for directions to head in. Any help is appreciated.
