P1693 has nothing to do with say the injection pump. It's only a companion code, indicating another code

 

well i got the codes checked by a ob something 2 the good one. I pulled up 9 codes 1st through last-P1693-P0237-P0122-P1698-P1689 i had two for some of them like the P0237 and the P0122. Can any one tell me how to fix this and what they are.

 

Kinda off for no start trouble codes. Could be a failed pump, could be a failed ECM.

Basic codes 237 is a map sensor performance
122 is a TPS/APPS performance
1689 is no communication between ecm and pump.

 

i did the apps adjustment like a week ago it was a .3 something and it is suposed to be a .555 no its at .52. how can i fix the 1689 i heard it could be a bad or lose connection but where do i start. what is the 1698? and how much fuel is supposed to come out during the bleeding, i have only done the 1st 3rd and 4th should i do more?

 

The pump may not be producing enough volume, Check all connections at the VP44.
I bleed all my lines except for 2 thats behind the intake horn. Turn it over may take upto 5-10 minutes of cranking time in some cases. Always try and start for 30-45 seconds and let the starter cool atleast 5 minutes. Tighten the lines and try again. Clear all codes before trying to start!

I've got a tester I rent out to make sure the VP-44 is the problem and not the ECM, let me know if you need it!

The number of codes would lead me to think failed ECM or PCM but not always the case!

 

i check the voltage to the injection pump and it was 12 volts is there any way i can see if it my ecm or anything i can do to fix it

 

Where are you at in NC

 

im in manteo a bridge away from nages head

 

There's some guys that run around that area, I'm sure they would be glad to help.
I'll also be glad to send you the tester to rule out the ECM causing issue.

 

im just going to try to borrow a buddys ecm he has the same truck
