7.3 hard start
My name's Johnny and I've been using this forum for years as a guest. Finally decided to join....a year later deciding to post for first time since my newbie post.
My ol 7.3 takes a long while to crank these days. By long j just mean longer than normal. I blamed it on the cold this winter, but now that's it's spring and warm in New Mexico, I'm not seeing a difference. Truck will usually send a puff of white smoke once she turns over. After its on tho...it runs perfectly.
