You can often get a bag of 10 or 25 bolts from Fastenal for the same price Ford charges for 1 or 2. You just need to identify it with hardware terminology, not a Ford part number, or bring one in for them to match up.
I have an 03 and last year my cranking issue was a slow starter. Didn't hear it getting slower over time but what difference when I changed it. Cranks in a couple seconds.
I've had all the other low pressure issues before as well. The cheapest repair by far was the starter.
I'd suggest 1st listening to another truck that cranks right away if you can to compare the motor turning over.
I use Torque Pro app for sensors hpop ficm voltage.
the worst issue was a blown gasket on the hpop. Cranked cold but not hot. Spent over 1k for the shop to find that
Gilbert: One thing you can do with Torque Pro, as long as your OBDII adapter is up to the task, is in the set up for the Adapter in Torque, set it to Faster Communication, then set up a log set of PIDs, and set the logging interval to 1/10th second. You can start logging before you hit the key. I would put Coolant Temp, RPM, and all the voltages for FICM and battery. You could add things like HPOP and the Cam and Crank sensors as well. If you make the list too long I doubt it'll handle that short of interval for polling and return/capture of the data (you could swap out PIDs, just leave coolant temp and RPM in all of them). I've used this mainly to watch FICM voltages at cold start, but also see cranking RPM and how long it takes to fire off. You will be able to know how long a crank you are really getting, Cold, Hot or whatever. You also just might catch something that isn't playing well with others when cold...
For comparison purposes: My cold starts are 1.2 - 2 seconds (though I have some logs that look like instant starts - just don't believe 'em), my cranking RPM is from the high 150s up to the high 180s. I have Oddysey Extreme Batts and don't see voltages (since installing them) below 11 on cold start; I also have installed all of Jack's early Cable suggestions and an extra Alt to Pass. Batt Fused Hot 6G one.
If you find that your starter is getting tired, look at the 6.4 as was mentioned. The Mean Green 6.4 starter boasts double the torque of the OEM 6.4 starter...

Well I just wanted to bring this to a close just in case anybody was interested. Never made time to address the long start and it finally left me stranded. Had the dummy plugs/stand pipes replaced also installed a 6.4 starter and now it starts like a champ.
