1994 F350 7.3 idi turbo ZF5 swap
Recently truck had been getting hard to start when cold and excessive cloud of smoke when it eventually started. Then it would idle and smoke. When driving down the road no smoke in mirror. When I let off the throttle it will smoke again. Not burning any oil from what I have seen on the dipstick.
I noticed several of the caps on the return lines were wet with fuel. I replaced all caps, o rings and hoses as well as glow plug controller and glow plugs since the original controller was melted (probably due to 2 broken glow plugs which were laying on the and shorted and melted the glow plug wiring harness) now there is no visible fuel leaking or seeping out.
Now after replacing the above when starting the wait to start light comes on shortly and goes out. Crank engine for a long time and it puffs smoke entire time while cranking. Eventually it will start and blow excessive smoke and then same thing. Smoke while at idle and smoke when letting off throttle. Truck has 192,000 miles. Unknown if pump, injectors are original or not. Would a bad injector cause this? Not sure where to start. I don’t have a way to check the timing unless I buy the tools needed. Nobody local to me in Plant City, FL has them that I know of to help.
Just kind of lost on what to try next to diagnose.
