ok using #19 and #20 there may be some data points that are common to the problem

right at the point that pressure spikes we have some odd numbers
the Target CP at 354kPa also has a VE1 of 10 and not the expected 100
VE2 is also 10
FUEL Total correction transitions from 100 to 95

Target CP drops to 311 at the same time as the actual CP ramps up

Although the older 5MinSoakWarmStart log exhibited the same numbers but did start ok
if VE1=10 and CP target of 354 is common to all the no start runs then we might have at least some circumstantial evidence to work with

can you look through the others and see if the pattern follows between starts and no-starts

the roller pump should be able to ramp fuel pressure up that quickly, it would be nice to match the CP log to actual pump status though

Yes! mechanical/hydraulic constant flow injection can be managed by a modern EMS
