No power/stalling

[baddkarmaracing]

I have a 99 f550 wrecker at work that has been having intermittent no power and stalling issues.

Codes I'm getting are
p0603 internal control module kam

P1316 idm codes detected

P1247 boost pressure low

P0340 cps circuit fault

What are the normal causes for these codes?

 

[baddkarmaracing]

I guess I should add that the cps is new and codes probably didn't get cleared

 

[Whytry]

Clear them and check again Do you have ae?

 

[Arisley]

Where did the CPS come from? Sounds like you might have gotten a bad one.

 

[baddkarmaracing]

Cps came from international I believe. I have a snap on solus pro scanner.

i ran the koeo test and got :
p1277 cyl7 (c) high to low side open
p1293 high side open bank1
p1294 high side open bank2

and koer code only got p0476

for some reason when i ran a contribution test it would never go thru the test. buzz test got gave me the same codes as KOEO

With those codes I bet it is often not running on all 8 cylinders.

What should I look for? I know the Cps is new. I guess something else worth mentioning is It is hard to start in the mornings but when it does start it runs fine. Almost acts likes its not firing when it does it. Cranks fast (new starter) and sounds good but just takes forever to actually fire up. It doesnt act like a gp issue

get in the data stream and look at the ICP data.. and then check the plug at the ICP sensor for oil contamination and possible bad ICP sensor

plus it sounds like it's either got a couple of flaky UVH's or possible a couple of injectors headed south..

Not sure why I didnt think of icp. I took notes of all kinds if stuff but not icp yesterday. If I have a chance today I will put the scanner back on it and check that. It might Have to wait till tomorrow because today is my busiest day of the week.

Anything else I should look at while I'm there?

 

[JLDickmon]

I still think it's got two problems...

pull the plug off the sensor and see if it's flooded with oil....

that funky buzz test is making me think very high resistance between an injector and
ground... could be the #2, which was the first problem child, could be one of the odd-bank ones, given that they were affected as well..

Ok it died today and wont start anymore.

Icp when cranking is about 2200psi
Cleared codes and none come back but still no start

Just picked up a cps from a friend so we can see if maybe the new one is bad.

He thinks the Idm may have gone out but since I can't read the Idm codes it's hard to tell.

Btw friend is actually a ford diesel tech
