Theres another code somewhere and I bet its P0216 or P1688....


Have you cracked an injector to see if you have fuel from the VP-44? Be very careful doing so and use cardboard to check for spraying fuel.

 

i dont really know what you mean if i have fuel from the vp-44. It still runs real good and everything it just smokes at start ups and once in awhile when you mash the throttle down. Does it have to be taken into the dealership to get those codes?

 

I mean, if you take a wrench and crack open number one injector do you have high pressure fuel spraying out?...

If you have a Smarty - it should be able to pull whatever codes you have.

I may have gotten ahead of myself. Are you getting any dead pedal or hard starts when warm?

If not, I would just drive it and see what happens.

 

I think thats what im gonna do. I havent got any hard starts or dead pedals yet ( knock on wood) But im gonna get that Airdog system done as soon as possible so i can get the fuel pressure and power back up. Hopefully it also takes care of the fuel pressure taking awhile to build up after startup. I guess ill just have to wait and see what happens

 

Now, to add some food for thought to this. If you install a AD or FASS that have such reliable pumps and the VP44 is damaged it will expedite the process of failure. So, what I'm saying don't expect the AD to solve the problem if the VP44 internals are damaged. It may not ever happen but you must be prepared to replace it if the P0216 code is present.

 

Ya im fully aware of that. I just figured if i do all that it takes one more question out of the problem. Im sure that ill be replacing the vp sometime this year. I just hope its not till later this fall when money is a little more available for pleasure

 

Find someone with a smarty box or decent OBDII code reader (some shops will do it for nothing) and check to see if you have that P0216 code in there somewhere. If it comes up at least you will know what you have to do even if it isn't right away.

 

I checked it with my smarty box and olny got the P0500 and the P1693 so i think i should be ok for awhile atleast

 

Well, then it is probably alright. What's a speed sensor signal? Some to do with your cruise control?

 

Ya it reads the speed off of the rear axle. The wireing harness wears out in them and whenever mine gets wet it throws a code. Also if i do a nice burnout it will throw it to
