Hard starting

[Patriot304]

My truck 88 f250 7.3 no turbo has always had a hard time starting. Guy I got it from said it had new glow plugs. It normally takes 20 secs to turn over cold. When I start it warm it does fine but even just sitting for an hr makes it hard to start. Any help would be greatly appreciated. Thanks

Sounds like air intrusion, imo.

Here's the thing - how long do the glow plugs cycle for? If it's less than like 10 seconds when cold, and the "after cycles" are just "click-click, click-click"(it's not staying on for at least a half-second each time), your glow plug controller is short cycling.


Air intrusion usually manifests with it firing up almost instantly, revving up and then dying a few seconds later, after which you have to crank for a bit before it starts again.

That's what my truck is doin after the wait to start light goes off it clicks
