Injector time!!!!
Good idea, Van. I'll check that this weekend, and log on Livelink as well. At least I had a gauge monitoring fp duty cycle, rather than finding out the hard way.
EDIT - just looked back over my prior three datalog sessions. FP duty cycle was between 89 and 91% at 6,200 rpm. Now I'm at 99% at 6,000, so something is definitely amiss.
Is the 14v an average of both circuts? Possibly the BAP is dying? Its very rare but possible. Silly thought but what is your altenator putting out? If its only charging at 10-11v rather than 14.5v maybe the BAP and FPDMs arent getting enough and the BAP can only put out 14v?
I posted that the voltage going to the FPDM's (from the BAP) is 17.2v at idle, so the BAP is fine. If you look at the datalog, battery voltage is over 14v, so that's fine too.
Even stranger - there is 14.2v going into each side of the BAP, 17.2v going out of each side and into each FPDM; 17.2v going out of each FPDM; and 17.2v on both sides at the fuel pump hat. And yet the Livelink datalog shows single digit fuel pump voltage for most of the log, and tops out at way less than 17v - which my multimeter says is wrong. How the hell can the datalog show single digit FP voltage at idle while I am simultaneously showing 17.2v on my multimeter??? WTF is going on?
