What is your question?
I hold down the pedal then it starts.Whats the problem? I've changed filter, egr valve , couple coils, throttle position sensor, fuel pressure regulator, plugs, air intake sensor, had the throttle body cleaned, had the catalectic converter checked, crankshaft position sensor, it idles rough also. It seems to happen a lot after it runs for awhile. Help me please.

u didn't say what the fuel fuel pressure is. how many miles, were the injectors cleaned, readings on mass air flow.
Does your truck have an "Idle air control valve"? My Escape had a similar issue, and replacing the IAC valve (two bolts, small gasket) fixed the problem. Basically, the IAC controls the air to engine under start/idle so it runs smoothly. This is pretty cheap to replace. If this doesn't do it, have you checked your fuel pump?? Could be fuel pump is about to go. If fuel pump is about to go, it could be causing the relay (under hood in fuse box) to shut off, and it will start up again after the relay has reset. Good luck!
Thanks for the info
I don't have the right tools for fuel pressure. Miles are 100,000, I ran fuel injection cleaner through it, don't think I changed the mass air flow.
