Had Truck Scanned need input on codes

[hopkins.phillip]

1996 7.3 Auto

P1705 Not in P or N (i figured probaly neutral saftey switcb)
P1272 Cylinder 2 B High to Low Side Open
P1274 Cylinder 4 E " "
P1293 High Side Open Bank #1 Right
Is this talking about the front two passenger or driver injectors? Could this just beeb a wiring problem?
Truck runs fine has a slight hesitation at times under WOT just when you first floor it. ICP was between 570-585psi at idle, hit the high idle it jumpes to 605psi then back to about 580. Gonna do a few part throttle and WOT psi checks tomorrow. Any help would be great

bump, anyone git anything

buzz test the injectors and then do a balance/cyl. contribution test, let me know what you get from that

i went ahead and ordered a UVCH, after i cleared the codes only things popped up on any of the tests was the P1293, the P1272-1274 came from a few days ago when i acidentally left the front driver UVCH unplugged.

on the good side ICP held a steady 2500+psi at WOT i was getting worried with the odometer getting ready to roll 400k she'd be getting weak, but all is good for now

ill do anither contribution test tomorrow, on the buzz test it does one multiple loud one, the the other 8 buzzs sound identical.

[STR8-6]

the buzz test is strictly electrical but that also means dont bother anymore with the UVCH connections, they are good

follow up on the contribution test

[STR8-6]

oh and to answer your earlier question, the drivers side is 2 4 6 8 starting from the fan... if you end up pulling them remember which one came out of #8 hole so it goes back

signing off for now
