Hard start help please
I'm new to the diesel truck world I got a smoking deal on a 05 f250 lariat 4x4 it had some whiskey dings and needed some tlc. Anyways it now has a new turbo and full egr delete,new up pipe,the Y pipe was removed and new bellows were installed braided style. Upgraded STC fittings, dummy plugs,stand pipes,oil cooler, thermostat,power steering pump,water pump,IPR,ICP, fuel regulator upgrade,MAP sensor,oil and coolant sensors updated oil line to turbo and drain pipe,the head gasket/studs were already replaced full magnaflow exhaust with down pipe no cats. New filters all the way around. So with that being said I've done a lot of wrenching but I can't figure why it's hard to start have auto meter fuel pressure gauge reads at 60psi KOEO and running, FICM stays at 47.8volts even when cranking or running and after you seem to have to pump the gas pedal it fires up and runs like I can't believe it's got 33" mickeys and I can burn them off any time I want. Just thought you didn't or wasn't suppose to pump the pedal to start it????
Anybody got some ideas I've read the forums checked anything that I thought would be relevant need help
