P1693 - DTC Detected in PCM

Put another 6 gallons in it.

Start at the fuel canister. Let it get full of fuel first. Tighten the lid. Then crack the injector lines. Crank the engine over for 30 seconds. You will need to do this a few times before you get fuel at the injector lines. once you get fuel, tighten the lines, and continue to crank. It will start to sputter. keep cranking until it can actually start on its own.

This is assuming everything mechanical is working such as your LP and IP.

 

P1693 - Indicates a fault code has been generated in the companion engine control module.

This is the only info I could find on P1693.
It sounds like you are not getting any fuel to the filter, which points at a bad lift pump (LP). With the hood up, turn the key on and you should hear the LP buzz for a couple seconds. Then bump the motor and the LP should run for over 20 seconds. If you don't have any fuel coming into the filter housing by now, the LP is probably cooked. 6 gallons should have been plenty if the truck is setting on level ground. I ran my 99 empty when the fuel gauge went south and all I did was put 5 gallons in the tank and had to crack open 3 injector lines before I got enough of the air out for it to start. It ran rough, but cleared up as soon as all the air was out.

Hope you can find your problem.

 

well theres another code in there, some time it can't read it. You will need a scanner. where are you located at maybe some one around you can help that has a smarty. Autozone will read them for free, but if you can't get it there that don't help.

 

So are you getting fuel in the filter housing?

 

Look at it this way. The stock lift pump can spew a pretty good amount of fuel in a short time period without the truck running. If you bump the starter (to cycle the LP) and have a banjo off before the VP-44 you will be able to tell that you at least have a semi-operational LP.

Just a thought.

 

ok im giong to try it all again.I sure do appreciate all you guys' help and support. Sometime I do things that are less than genius caliber and i pay dearly for them.Wish me luck .BE back in a few.

 

what is the VP_44? and a banjo ?

 

the vp44 is the injector pump the banjo is the hose fiting that goes to the lift pump look at the engine diagram on my sign to see where it is

 

the VP is the pump...

banjo is the bolt with a hole in it...just like on brake calipers...

ok, now i have evidence of fuel up to injector fittings. Its no shower or even a squirt , but there is moisture on the threads and on the intake . Like about a toothpaste cap full.

 

That could be just left overs.

You really need to get a scanner on it.

You will be looking for P0216 as the worst possible news. You could still just be out of fuel, but it sounds like you have some time into it.

Did you put some more fuel in it?

Where are you located?

 

Im not exactly sure, but I "think" that code is just saying that there was a "fault code" generated by the computer. It is typically followed by another code that is more specific. Im sure if I am wrong, someone that knows will correct me.

ops.. Sorry.. Didnt see the 2nd page.. This is kinda old news...

 

dont know the code but to pressurize the tank is easy, it takes two people to do so. first person holds a cardboard cutout of fill neck with tiny hole, second person uses a blow gun in the small hole should allow about 8 to 30 psi to get in the tank but you may blow diesel back in your face so have on glasses if you try. also check out other threads on vp44 that may be your code. looks like i have seen that one before look on the help just work backwards tell you find it best of luck buddy

 

i did it once and my old man gave told me somthing i feel that i shouls pass along " its just as easy to keep it from half tank to full then it is from empty to half"

 

Ok you guys have been "on point" with your help and advise. I mean to tell you its been a struggle , but I give you my word I never cussed her! The fella that mentioned possibly having to pressurize the tank ,had it.! The guy who wrote about the cardboard fuel neck cover was real close , but I tell ya what,,.An old metal gas cap can be drilled to recieve a tubeless tire valve then be used to pressurize the tank . In 30 sec. "charline" was up & runnin!
THE bad news is for us 2000 24v owners, we will no longer be able to find a motor mounted lift pump for our trucks. At least here in CA. they are only going to sell the tank mounted pump. So needless to say this would make for a long afternoon.
Keep your heads on a swivel!!!!! THANKS
