hey guys how u doin im new to this site, but i have a simple question.. i have a 2001 supercrew with the 4.6L and i have trouble startin it when its cold.. ( in miami thats like 75-80). i have to let it turnover for a while and when i let go of the key, is when it starts up. Other than that, the engine runs fine.

 

check simple things first. fuel filter,air filter. how old are your plugs?? 9 out of 10 times its a simple problem.

 

yea plugs are fairly new and the filters are new, thats the first thing i did

 

ok check fuel pressure at the rail.
