F150 hard to start
Howdy all,
My 99' F-150 is taking 3 - 4 cranks to get started. It has a new interstate battery that the previous owner installed prior to me getting the truck. It almost seems like it is starved of fuel and I was going to replace the fuel filter for starters. But before I start replacing stuff I thought I'd see if there is something else that might cause this problem. I checked in the search function for hard starting and got the reply no matches found.
The truck is a 5.4L auto 227K miles with meticulous maintenance by previous / original owner. Receipts for everything.
Thanks,
Craig

Don't know, haven't tried this.
On edit - Went out and waited 10 secs and it started much easier. However, it still didn't fire right up. I am comparing this to my 03 Expy with the same engine that when you turn the key there is no delay, the engine fires right up.

Fuel filter first. How to clean a throttle body is a sticky thread in the Engines forum. If the IAC is bad, that usually causes cold idle issues - and sometimes warm idle issues.
Look through the receipts and see if it's ever had an intake cleaning by machine - look for Motorvac or BG. If not, it's well worth the 75 bucks or so the dealer charges to do it.
It's also possible the EGR and PCV systems are getting gunked up with that many miles - unless, of course, that work has also been done.

Thanks for the input and I'll see what I can find out.

I finally had time to mess with the truck and I have a question.
A) 45.00 for an IAC sound right? That's the cheapest I have found and that is at Autozone. Other places are higher.
B) On the passenger side of the intake there is a 3 way hose connection. The center hose looks like it has been sucked flat, is this normal?
C) Thanks for the help.
