Another wont start 6.0 ....

[ChiefRocka]

Hello everyone ....

I drive an '06 F350 Utility body truck for our familiy run garage door business.

When under warranty, it was back and forth to various dealers (towed twice) for 'no start' problems.

The first problem was a LOOOONNNNGGG crank to start when cold.

Now the problem is it wont start when hot....it seems to crank at super speeds, but I'm sure will kill the batterys or starter before it starts.

As it warms, you can shut it off ... then notice a longer time to start each time the temp increases.....Untlill finally at operating temp, your done!!!

Sitting next to Chevys and Dodges at construction sites can be a real test of pride when your Ford wont start !!!

Anyway .... What do I need to check first, as NO dealer in town can seem to fix this problem ??

I would like it to start IMMEDIATELY when cold, and HOT !!!

Thanks !!!

I'd suspect a HPO leak. STC fitting or dummy plugs. Also, check you FICM voltage too, just for giggles. There's a great thread in the 6.0 tech files, under repair help

Great advice.

I will give it a shot !!

[ChiefRocka]

Actually, which one would you suggest I try first ??

Will this be a process of elimination thing or what ?

You should see if its throwing any codes, then go from there. 6.0's have enough sensors and shat that they can pretty much point you right at the failed part. Be sure to use a quality scantool like AE or maybe take it to the dealer to have them check for codes. You will need that same type of scantool to check different sensors and pressures to get it figured out

If it was storing codes, would the 'wrench' or 'engine' light be on ??

I forgot to mention that .... I have no check engine lights on (other than my airbag light which flashes '27' which I think is a bad dash pass side switch)

It did have warning lights on before, when it was towed to the dealer.

One of the dealer I recall mentioned they replaced the HPOP, Turbo, various injectors....

How much would I expect to pay for an AE ?? And where can I pick one up ?

Sometimes it will show the wrench light but sometimes it won't. AutoEnginuity can be gotten from Strictly Diesel, which is who I bought mine from.

That's where I got mine from too, for 350, witht eh enhanced Ford bundle (a must have)
