How about this? Your glows don't come on till 15 seconds into the cycle and you turn them off shortly after that, 20 seconds. Double cycle them then try a cold start. Depending on the temperature, I could burn the plugs for up to 30 seconds. Doesnt change.I would half the timing change and go back to .95 mm to see if that gets you better starts. And just what condition are the injectors in? I would be pop testing them in the cold to see if some weirdness with cold expansion is having some effect on delivery. I have no idea on the injectors, I wanna say good? I run ATF and Diesel Power Service regularly.All the other normal issues seem to be taken care of, slow starter, bad battery (honestly an F350?), fuel in the lines, timing and leaks.Yup one of the two out of an f-350, not only that but the battery is a reman and ATLEAST 5 years old.. it was around in the truck before i knew of it.. so 5+ years old, still measures at 12.61V. This was in my 81 just after i got it out of the barn it sat in for 6 years and running. Oh you mentioned you don't drop the clutch when starting, but do you give it that 1/3 down on the accelerator? That seems to help mine as it allows fuel to be delivered and pulled to the pump and not incur a restriction of any sort on the pump.Yeah, scratching our heads here too.You need a garage man, 50 degrees F (10C) , not a problem starting then right? I'll try dropping the clutch next time, see how that helps.. i do have fresh 75w tranny oil, so i dont think it adds too much to drag. I do push the accelerator down the little bit, but only recently as of this problem. I have a 2 1/2 car garage, or a 4 mk1 garage . But it is currently my tools and my '67 Cougar. This was taken after top end gaskets, and figuring out the bastard wiring the PO did to get the 87 motor and its electronic distributor in there.. She runs real good though http://www.youtube.com/watch?v=jt3jOpUS_8k
