can someone please 'splain this?
1995 ford f150 automatic 5.0. i bought the truck 2 weeks ago and drove it 80 miles home,no problems,ran great. I knew the title wasn't clear when I bought the truck,but didn't have another weekend to wait to pick it up,so went and picked it up and parked it at my house until i got the paperwork for the title,which i got yesterday. Anyhow,the truck had set for the two weeks without being started. I was going to drive it some last night because I got it licensed and it is legal to drive now. wouldn't start!! just cranked and cranked. I tried several times,no luck. i could hear the fuel pump cycle when I turned the key,so I thought it was getting fuel. Didn't have time to look at it/work on it last night,so went to work on it tonight. Truck started up so fast it scared me!! hardly had to turn the key!! what gives? just wondering why it cranked and cranked and didn't start last night,but fired right up tonight? nothing really to fix if nothing is broken is there?

Could be all the cranking you did on it last night brought the fuel back up to the injectors. I'd check the pressure regulator (fuel). It might have a little hole in the diaphragm.

thanks,steve. I was thinking something along those lines,but had never had the problem of the engine not getting fuel and having to crank for awhile before starting since the age of fuel injection.

Or you could be on the way down the famous "Coil, ICM & finally PIP replacement" path. But that usually begins with a dying/no-start condition.
Do as Steve suggests & check for fuel in your regulator vacuum line.
Good luck with yer' new toy.

If it was the type of day and the right time of the evening, plus the fact that it hadn't started for over a week, It could have been condensation in some of the ignition which dried out by the following day.

Or the first cranks could have caused a no start because of a bad/marginal fuel pressure regulator or/and bad check valve in the fuel pump, and the subsequent cranking caused the engine to flood. If it occurs gain--after lengthy cranking--depress the acceleration pedal to the floor and continue cranking--just like the old carbureted engines.
The computer will turn off the injectors at cranking speed when the fast pedal is depressed completely . And I bet the truck will then start right up. When it does--release the accelerator pedal.
