Hey fellas I'm new to this but heres what i got going on.

I got this truck recently f250 93 7.3 idi. Has trouble with hard starting.

I got a high torque starter, put that on.
stain

Sent off the injectors to be rebuilt from a reputable source

Got Glow plugs ford oem

Got a upgraded fuel lines replaced the plastic ones with the stainless ones from that fella on ebay who makes them

I got a heater fuel delete kit solid aluminum with a upgraded wix filter.

Im pulling the radiator to have it serviced and or re-cored.


What else am I missing. I want it to start right up. What about other fuel lines, any one know the part numbers on them and were to get plus any other recomendations


thanks I hope I explained everything well, IDC what the oligarchs say this forum is way better then ai.

Try starting fluid if it starts right up, probably something wrong with your glow plug system. If you bought your glow plugs from eBay or Amazon they are probably fakes.

My first guess would be air leaking into the fuel line. This will cause a very hard start first start of the day. You have done almost everything needed to assure a good start BUT the fuel lines. Check every injector line and the fuel line to the injector pump (HPOP). Best of luck.

Another vote for air intrusion - Ive got air intrusion in the fuel lines I havent had time to track down and fix (Probably injector O rings in my case). Hard start after sitting, even just overnight, but the rest of the day starts perfectly. Dont have any part numbers since I havent done it yet but if youve done Ford (Motorcraft) glow plugs, high torque starter, and everything else you mention that would be the last thing Id be worried about.
