KR Services is the guy I bought the original IP from. The IP had a one year warranty. He identified a part in the IP that caused this issue. Sorry I don't remember what it was called. It did correct the issue.
There is no vacuum at the gate at idle. There is vacuum coming from the pump...
Current status
Been a while. Installed a new IP per KR services. He said there was an issue with the pump because of the rpm management was out of control and it blew black smoke on acceleration. Well that was it. It is running much better. I got in the GMTD scan. And it appears I might...
Replaced the coolant temp switch. That fixed the high idle and long glow plug issue.
Checked the vacuum pump. It was not providing vacuum.
Replaced that and eliminated 78 Wastegate Solenoid Fault.
Also dumped the burnt trans oil and changed filter/oil.
Cleared codes and test run out...
I'm not sure how to check he IGN voltage. I can verify the altenator tomorrow. I tried a different PCM with no luck. Now that I'm thinking about it I think you are right. I don't think the turbo is working. That would match the power loss feeling.
Made sure the eprom was seated well, removed it reseated it. I tested the fuel pressure and it was about 5psi before the IP. I changed it with one I have that was getting 10psi. tested and really did not notice any difference. Then changed oil and filter. Cleared codes and it ran perfect...
I ordered the scan tool. Looking foward to using it.
The Chip is BPDN 16217518
It has been great for a while. Just started getting less and less throttle control.
If it was modified it was the previous owner. I have no idea on that.
Yes I have DTC57 with the DTC67.
Here is what happened today. Tried shorting the CTS and IAT. The glow plugs were maybe 3-5 seconds. Beside that change the rpm issue has not changed. It is currently reving up to 2k sitting in neautral. The new PMD came in, no change. So I'm getting low glow plug time and fast idle, so that...
The other code was 67 Torque Converter Clutch (TCC) Solenoid Circuit Fault
I plan on working on the truck today. I should have more info today. The IP was purchased 1-17-2010 from kr services. DS4831-5521
You all have more faith in me than I do. I will reset the codes and try some of the recomended test this eveing or tommorw. I'll get the exact codes and post them. I agree its not smart to throw parts at it. The place I bought the PMD is sending out one no charge, just have to send one back...
I unplugged it and had no difference. I ordered a replacement pmd.
The other code was something to do with the torqe converter. Ill report the exact number when I get home.
There is only 2 codes
Truck has just got more and more sensitive over time to the throttle pedal. For a long time is...
Limp mode-It's not running in Limp mode it is running it attack mode.. It's wants to go.
Cleared code-I tried clearing it by removing the battery leads.-no help.
New Stuff-Reman IP from KR services,Bullet proof PMD
Glow plugs on cold day maybe 10-15.. That is a good clue. It does seem to...
Cranks instanly, runs like a beast. Issue is it has no throttle responce. It is like 2-3k rpm with barley a touch. New IP, acceleratpor pedal, new PCM.
- What were you doing when it happened? Normal driving
- How was the truck running fine before this problem appeared? fine
- Has this...
