FOXY005

First a little history
I bought the truck new and it always started after 6 or 7 revolutions of the starter.
At 75,000 miles I had a long crank time before it would start, took it to the Dodge Dealer and they replaced 2 injectors and said it was good to go.
Drove it for a week and still had long crank before starting, took it back to the dealer and they replaced the remaining 4 old injectors. Which fixed the starting problem. Back to 6 to 7 revolutions to start.
At about 98,000 miles I started to get a longer cranking time before it would start it would take 12 to 15 revolutions.
I took it to the dealer and they said they checked all the pressures and all were within spec, could not duplicate the problem said if it starts within 5 seconds that is considered within specs.
Well having driven this truck since new I know what normal should be and that is not normal.
At 103,000 miles I had some crank times that were 25 to 30 revolutions before it would start, took it to a independent fuel injection service that is Chrysler and Bosch certified. They checked the fuel pump minimum of 10 pounds of pressure, checked the CP3 good, releif valve good, checked the injectors with the scan tool all good replaced the FCA as a maybe that was faulty but it made no difference still had the long crank before starting. Also no codes were set.

Went out one day last week at lunch time and had 3 cranking session of 25 to 30 revolutions to start it. That same day after work it took 4 extra long crank sessions to start the truck.
While I had it running I took it back to the independent shop and parked it in their lot and called the wife to come and pick me up, while I was waiting for the wife I tried to start the truck and it started in 12 to 15 revolutions ??

The independent shop again tested the fuel pump, CP3, injectors, releif valve and anything else they could think of and found nothing out of spec. Said it would start for them every time within 3 seconds and 5 seconds was the acceptable standard.
Of course it won't misbehave when it's in the hands of the mechanic.
I drove it for several days with cranks of 12 to 15 revolution before it would start.

Last night 2 extra long cranks before starting and again this morning 4 extra long 30 + revolutions to get it to start.

This is driving me nuts any suggestions anyone, I hope I just don't have to start throwing parts at it to find it.

I am guessing it's new injector time but they only have about 30,000 miles on them and I don't want to spend that kind of money to find out it's something else since they cant find anything out of spec.

I use Stanadyne Lubricity Formula and Performance Formula at each fill-up I had hoped that would prolong my injector life span.


Any and all comments will be appreciated.

Thanks in advance.

What fuel filter do you use as not all fuel filters meet OEM specs? The only 3 fuel filters that meet Dodge/Cummins Spec of 7 micron or smaller and also separate water out of the fuel are Baldwin PF7977, Fleetguard Stratapore FS19856 and the new Donaldson P550800.

I am using the Fleetguard from Geno's Mopar 4-2-1 kit and it was recently changed with no change in symptoms.
