Rock Auto is where I picked that one up. $42.CAD for mine. That's why I don't want to rush out and buy another. I think I had actually selected AC Delco originally but changed to Standard so they could all ship from the same warehouse saving me $35 CAD. Should have gone with my gut and paid...
OK here is what the tests revealed
Historic had a code 34 to start with (they crop up randomly )
Unplugged the CPS was hard to start but ran once started (produced a DTC 19 Crankshaft Position reference Error as expected)
Plugged CPS in and unplugged the OS was really hard to start...
Looking at the before and after (snap shots) for the fuel rate @ idle it is identical. I guess I marked it good and got it back perfect. I could as you said bring it toward passenger side slightly to get that 7-9 range.
Fuel rate @ idle = 11.56 mm
I did not try the starting with CPS unplugged again
Are these Historic Codes or would they only show in Current codes, I will do some more test to gather that info.
I was thinking too if someone had time to run Time Set and Learn with CPS unplugged first, then OS...
Pulled OP and cleaned the window...not a bad job to do. This however did not fix the problem.:mad2::???:
So for some reason unknown I could have a bad
CPS (new ....Standard brand)
OP have no way of checking it. If I absolutely new it was bad I would buy one (probably dealer item and...
I had just finish finding and reading that thread, Doesn't look too bad to do. If I just remove the 6 torx screws and lift it off should I be able to clean it? Is there like a little lens on the bottom of that sensor? I seem to remember guys doing an Optic bump back a while ago. I will not...
Fuse... never thought of that...thanks, I know the LP works.
Actually with the crank sensor disconnected I could not start, but maybe did not try long enough. With OS disconnected it was hard to start but would not stay running. Don't know where to go next.
To clean the OS is it hard to do...
Different PMD and same results, Does any one know what the #8 fuse in the inside fuse box is for - marked Crank (10 amp) no power to either side key on or off nada! Have the batteries disconnected for 1/2 hour or so to possible reset ECM,
only code is the nasty code 88 cause it is at +2.02...
I have got the original PMD that used to be on the pump but carry it in the tool box now. I have to rig something up to mount it to for heat sink before I can try it. I tried moving the pump to the passenger side about .040 and tried to run Time set and Learn and it still stalls with tons of...
Well I got the pump moved towards the driver's side about .040 and it is still not lined up even with the notch. I don't want to do the Set and Learn until after I am finished using it tomorrow. Just in case things go bad (you know how that happens). I am wondering if my Actual injection pump...
Will the more I think about it the more I think I have to move the IP more +. With it giving a -2.02 before and the code 88 it was even more negative and we don't know how negative. Also I was getting random code 34 which probably means the stepper motor is having trouble controlling the...
If I go into Time Set or Learn it will stall out engine. So I can't look until I figure out why. In the snap shot it shows Actual injection pump timing at 33.7*, what should it be? Will turning IP to passenger side bring this down to what it should be, what every that is. If I do this when...
Making progress
Made some progress, was able to get through Learn by increasing idle long enough to get a -0.7 TDCO. Now the code 88 is gone and truck seems to run well. Will be interested to see how it starts cold at this setting. I have included a snapshot of relevant info. I don't know...
The CPS was a Standard and was comprised of the sensor with a metal mount bracket already assembled. when installed it was according to this reference picture.
Notice the two dots. It needs to be installed with those vertically aligned and towards the radiator.
@ Buddy I have set timing with this chip, I had no problem getting -1.94 or -1.75 before the HG and CPS the pump was not physically moved in the 4 years I have had it. The PMD is only six months old with harness from Heath, don't know the resistor ohms. Engine runs good once warm and timing...
AK Diesel Driver, after looking at my timing marks and what it should look like according to Buddy's picture you were right that it needs to go towards passenger side. Now to get the tools to get it done. Thanks
