Hard cold start
Got a 99 f-350 , as long as it is plugged in it starts fine. but when it's cold you have to cycle the plugs several times and it might start and lope and cut off if you don't give it fuel. No power at all with pedal on the floor untill it warms up. Glow plugs are new, system works fine,fuel pressure @ 58 psi. , hpop tank full. New turbo last summer. Once it gets warmed up runs great rest of day,no problem starting. No codes , no light coming on. Thinking along the line of g-rator may be worn out. But as soon as engine starts oil pressure fine. Oil changes every 3000 miles. No smoke cloulds when cranked. Compression @ 400 psi in all cylinders. Has 175,000 on it, does not use oil. I have tried to find a adapter to fit the hp oil gallery so I can check for 500 psi start pressure in each head,and to see if it goes up when pedal is pushed( have a 4000 psi setup) but the threads are 1.25 pitch 12 mm. Anybody get any ideas? I have all-data and I've went through their system.
