1993 Ford F-250 5.8L Starting issues
I have a 93 Ford F-250 standard shift with the 5.8 engine in it. The truck has a hard time starting when it is cold. You have to cycle the key 20-25 times or put a shot of starting fluid to it before it will start. Once started the truck will run fine. After it warms up it seems to start easier. I have had the fuel regulator recall taken care of, new fuel pump and sending unit, new water pump and thermostat. I have checked the timing and it is fine. Checked the inertia switch and replaced coolant sensor. If anyone could help me with my situation I would greatly appreciate it. COuld it be the IAC, Ignition switch, or TPS?

Whats the mileage on the clock?
Since you state that the truck will fire off on starting fluid, and THEN will run 'fine' (idle/cold/stable? no smoke?) pretty much eliminates the IAC/TPS ect. or base engine issues as any/either of them if a falt for idle basics, would probably still be there once the truck fired up on the starting fluid cold.. Seems it would also cancel out any ignition problems too it it LIGHTS OFF on starting fluid immediately..
Being that the key needs to be cycled 'multiple' times to get an eventual start would surely get a fuel pressure/volume test from me... Even If the parts have been replaced, and even more so if it was done by someone else.. Checking for pressure/volume would at the 'very least' eliminate fuel delivery as a culprit, at least at the 'supply' end of the need.. It would also be a good way to check for pump 'on times' during a crank, or key cycle, to check relay/circuit problems that may affectfuel pressure on a start..
