Truck is "dead in the water"! HELP!!
my truck was cranking a little slow so I took both batteries to Interstate Batt and one of them showed good charge but a bad cell under load so I replaced both, id say take your batteries have them tested, these trucks are sensitive to electrical gremlins

Electrical
just the other day I looked at my ground on pass. side near battery with the gray connections ( 2 of them ) I know a ground should be solid with no splices, so I slid it apart and there was no resistance, I took the plastic gray connecters apart ez to do and reconnected and it slid on and off very easly, I got the solder iron and soldered the connections, at Boeing we had to do ground stud resistance check with ohm meter I don't remember the specs but anyhow I wished I had ohmed the ground before and after, the factory made them this way to make assembly easier and quicker, with time im sure vibration heat and cold cause the connections to lose their bite and now we have the symtoms, I also took all the grounds on the metal and cleaned to bare metal and installed a washer then ground then bolt for a better contact, also silicone should be applied to protect the ground bolt or screw,that's how we did grounds at Boeing. it seemed to make things better on the truck. I don't know if this will pertain to your problem but thought id share since our trucks are built the same

starting trouble when hot

signs of a bad vp44 bad mpg?
check your wheel alignment.

Trans won't shift 1-2 unless I take my foot completely off the pedal
sounds like the kick down cable is too tight, it will cause late shifts and wanting to downshift, my shifter is a little out of adjustment so I usually go from park to Low1 and shift into drive and the tranny will shift normal, what im trying to say is it can hang up between gears and cause problems. you need to see if the spring is still attached to the kick down lever on tranny too

47RE slamming into reverse in low range?
Just a sign of a healthy tranny, a higher performance VB will go into gear quik but as you said a torque conv and idle speed will determine how hard it hits going in gear

Did the Alt. test
Got the proper relay from autozone 19273 wired it up cranked fuel psi back up to 19 and it starts with just a quik blip of the key. I cut and spliced the wires from the LP so I didn't have to cut into the factory wiring. I think I will do like my drag car and drop the tank install a #8 bulkhead at the Bottom lowest point and move the airdog 100 closer to the tank and replace the banjos with AN fittings extend the wires, the pump will then be gravity fed and work ezr and supply all the fuel it needs and maybe add a t fitting to sump the tank now and then to keep it clean. - - - Updated - - - Got the proper relay from autozone 19273 wired it up cranked fuel psi back up to 19 and it starts with just a quik blip of the key.

Did the Alt. test
Will a Autozone RL44 relay work ? it has 85 86 87 an 30 There is no 87 and 87a only 87.

Ill be mainly driving empty no loads nor trailer so ill give the throttle a good stretch, im in flat area except for a tall bridge which I hope the VP will never go out on me on anyways the tall long bridge is a good test road to put a load on a vehical, ill have to find your diag. to the fuel pump relay and bump the pressure back up. the truck is all stock , no programmers, just straight piped.

As far as cranking pressures you hit it, it bounces 9-11. Like I said iv backed down pressure it idles 14.5 - 15 psi . Ive never put my foot to the floor but at 16-1700 rpm about 65mph its about 12 - 13 psi and seem to be at that psi at even lighter throttle . I seem to remember when the idle psi was at 18psi it would cruise at 15 - 16psi . I just don't wanna start doin wot runs and get bugs coming out that I don't want to see lol, I did run it about 3/4 throttle one time and pressures stayed at about 13 and seemed to loosen or wake things up in the motor because it has ran smoother and accelerates better and gauge on turbo seems to spool up better than it had before and probably because it had its first drink with 2 cycle lube mixed in it. Im a little lost on the cranking pressure test you just described by pulling the relay ? Will I then need to hook a gauge to the VP to test the pressures coming out of the VP ? - - - Updated - - - As far as cranking pressures you hit it, it bounces 9-11.

I hope I remembered that correctly.

It was at 18psi but then was getting the hard to start so I backed it down to 15 psi to able the starts a little easier as far as the VP psi output I haven't seen any test for that are there any ? Maybe I should crank the LP psi and do the relay ? I was thinking while at cruising rpms the fuel is going through the VP isn't that suffiecient to keeping the pump cool and while at idle at 15 psi the return is allowing the fuel to pass and cool ? im no expert by a long shot so plz educate me on this.

Did the Alt. test
Just trying to take all the steps to keep my vp going strong as I don't know its history as iv only owned the truck little over a month now. So with meter on DC engine running = 13.97 V switch to AC =.03 - .04 according to Mikes vid .1 is the limit ? so im hoping im good to go for a good while its a quik and ez check. with over 300,000 miles im assuming the VP maybe its been replaced but I don't know, it did still have a carter LP but its replaced now with a airdog 100.

4" Exhaust
What did you have prior to the change ? Is your truck modded or all stock ?
