Well figured out starting issue.... The starter just locked up... Fixing to post up data on the start up try

It should have started with that data, but there are a number of PIDs missing to get the whole story. Click that last link in my signature and you will get a very detailed description of what to look for.

Unless I'm reading it wrong, he never dropped below 10 volts while cranking. Manual says something like 8.5 doesn't it? I know my truck will start if it drops down to 9.3 volts while cranking.

 

No, you're reading it right.10.3 was the lowest.

 

Usually 8.5-9.5 is the threshold. Voltage shouldn't be his issue at 10v.

 

tjustice,

is this last data log before or after the starter swap?

IF you like, do some more datalogging on a WOT run and log ICP, ICP Duty cycle, vehicle speed, rpm's & engine voltage. Then either post the data or send it to me and we'll throw it on a graph so it is easier to read.

Also, what trouble trouble codes are you seeing? IIRC 1211 should be set if the duty cycle goes higher than something around 53%. You should have at least that code with that high of a DC I would think.

Edit: Here is the link Tugly was referring to:

http://oregonfuelinjection.com/pdf/f...diagnostic.pdf

 

This is yet another case where I would need to see FIPW. For all we know, the injectors aren't even firing.


I've read many specs on minimum starting voltage, and I've had a low set of batteries - yet Stinky still started. The way I see it, the spec means "If it doesn't trigger the injectors below this voltage, don't be surprised".

 

That was data from over night sit. Starter locked up during that test... Just finished putting starter on, mother sings like a new 7.3 now....
