I have read a ton of information off of this website (Thats why I bought a CTD) and appreciate all of the contributors. I FEAR that I have a Fuel Injector Pump problem and hope that I am wrong. My symptoms are: NO POWER after a time period of 6 hours...(not running-cold) meaning the engine revs fine to WOT in park but in drive in the AM idles strong for 2 minutes and accelerates to exactly 5psi boost pressure and hits a wall with a noticable turbo dump hiss sound and snap into the next gear that could cause whiplash. No more RPM's, nothing. It crawls at 5PSI boost pressure with slow acceleration until the temperature guage starts to register 140 (roughly 2 miles) then ***** on walls again with no problem there-after. It is a snappy jump when she lights off because I don't realize how far I have the peddle pressed until she "wakes-up". My Edge module is installed and the codes that I saw were in this order- 0500, 1693, 1693, 0216. On a recent trip I did notice a no power condition while climbing a steep grade until I let off the gas and then reapplied power and she went like the rocket that I built. I am really hoping that it could be a wastegate sensor, o2 sensor or anything but the PUMP. I voided my warrantee at 100 miles. I do understand the need for a fuel pressure guage and will "surf for one" when I post this. Thanks in advance. Wes

 

You need to put something in your signature so we can see what you have for a truck.

 

Being that you have the user loved 0216 code, you have a pump problem. This code is generally the death rattle for the 44 pump. however, it could run for a while, or it could go poof instantly. its entirely up to you how long you wish to run it. Good luck with it.

 

99 here is a list of codes. I do think one of your problems is Vp44. fill out your sig. I'm sure others will chime in and help!

Good luck
Gary


P0216
Fuel Injection Pump Timing Failure

P0500
No VSS Signal

P1693
DTC Detected In Companion Module

DTC Detected In PCM/ECM

 

I updated my signature to show mods, but I forgot to specify that I have tapped the fueling wire with the edge module. And j-hooked the turbo (boosts to 30psi from GO) Could that affect the codes that I am reading? Thanks in advance again. Wes

 

Wes, sure sounds like a injection pump failure to me. Have you checked your fuel pressure. You can plumb a cheap pressure gage off the schrader valve on the vp44 and that will tell the tale. Your truck mods sound great. I think that if your warranty is voided the next thing you need is a hot rod vp44 from industrial injection. It'll give you a more dependable pump and more horsepower from what I understand and also a fuel pressure guage of course!! Another thing to consider is a better fuel delivery system, lines and a new lift pump that I think you will find you need. Your mods are using more fuel than stock and one of the best ways to keep the injection pump happy is keep it supplied with fuel. I like the idea of relocating the lift pump back at the tank and bigger fittings and lines to keep the pressure up. Vulcanweld can help with that among others but he is pretty reasonable and a good setup imho unless you want to spring for a fass system! Good luck!

 

Good advise Barry. I have similar mods and when I first installed my comp, my 44 died on the spot. ,,,,,Oh well, learning more and more about these CTD's! I should of read more about them before doing the mods. But, that would be in a perfect world! Anyhow, Wes, I start with the fuel pressure. That is extremely important. If that is good, no doubt in my mind it's yer 44. I know you don't want to hear that but it seems evident. Especially if your over 100,000 miles. If you do replace, difinetly go with a hybrid. Good luck.

 

I would not leap to a bad fuel injection pump right away. What the code 500 represents is that the ECM is not seeing a vehicle speed reference signal. Without that, the fuel injection regulation logic will not properly function, and your throttle position sensor will also not function properly. That will give you fuel system related errors that pertain to buss failure, pump failure, and various companion codes that can send you down a rabbit warren looking for the trouble in the fuel system when it is a sensor or connector.

The 500 code would lead me to look for a bad engine to body and body to frame battery ground. Also, check your speed sensor to be sure it is functioning and that you do not have a mass of wet mud on the speed sensor connector under the truck. Check your throttle position sensor and be sure it is clean and reading proper resistance, as it can also ground out the signal from the speed sensor if it is failing. Once those are out of the way, check your connections to your PCM, the loom through the firewall, the lift pump, and to the injection pump to be sure they are clean and protected with dielectric grease. Then do the TPPS reset procedure outlined in the Tech Facts section, and see if that does not solve your immediate problem.

If this does not get you up and running, you need to complete a fuel pressure check on the outlet side of the fuel filter and make sure the lift pump is functioning properly.

 

Thanks for responding....now I have an ulser...just kidding . The fact of the matter is that I only have 38k miles on her. I have been doing a lot more reading on the HELP forum and I do not have the associated smoke problem that seems to be prevalent with the 44 failure. Yet the darned code 0216 is there. I never knew how to read the codes until the night I posted. I think that the only way to reset the codes is to disconnect both negative leads from the batteries and wait an hour or so? I have no idea when they were tripped. I never got any warning lights. I have also had my engine compartment pressure/steam cleaned. I now understand that that is a NO NO. And upon inspection of my Edge box I have noticable corrosion on the jumpers and jumper pins (Mounted under the hood). What should be my next sequence of events? Reset codes or unplug the module? Or both at the same time? And another newbie question, can I leave the fueling wire tapped and just replace the factory MAP connection or do I need to remove it as well? I am sure by now that it is obvious that I am not the mechanic. I had coworkers do all of the modifications....they are jet mechanics and I just clean the floors when they are finished. PLEASE tell me that this info alters my next step of just purchasing a new vp-44.

 

RCW... THANK-YOU SO MUCH!!! I love to here alternatives that might be a culprit that I can investigate before having to invest another fortune into what I believe is the last truck that I purchase. Did you read my last post? I added more info that gives tech savy people more insight into my dilemna

 

I think you are on the track of the real problem with the corrosion. Get everything cleaned up, coated with dielectric grease, and back together. In fact, I would remove the Edge box until you have solved the problem, it makes one less component to worry about while you troubleshoot.

If you have corrosion on the terminals, then you also have it in the throttle position sensor, and that is most likely the source of your real trouble. Do a search on here and you will find a procedure for cleaning that little stinker, and it may save the the price of a new one.

 

Good info RCW!! I thought that the 0216 code was pretty much the end of the pump! Thanks for the education!
