What does Ecutek variable “Fuel Rail Pressure MPA” represent (no startup)?
 

My FRS currently is cranking but not starting, so here are 2 datalogs

CURRENT (cranking with no startup): https://datazap.me/u/eazy-v/2013-frs...g=0&data=12-17

2018 (startup fine): https://datazap.me/u/eazy-v/2013-frs...g=0&data=12-17

Any ideas of what might wrong?

Fuel rail pressure monitored is the DI fuel rail pressure.


unlike fhe port injection pump in tank that is regulated to aprox 60psi constant, the di fuel rail pressure is variable and controlled the the DI computer and engine ecu to vary the di fuel rail pressure depending on di demand, the di system manages both pressure and injectpr pulse width to deliver required amount of fuel

These cars start on 100% port injection


but ensure all bolts are in and tight on DI computer on side of engine

Ok I’ll check that

So, would this indicate that the in-tank fuel pump has to be working since it would be sending fuel up to the DI pump? Or is the DI pump on a separate fuel line to the gas tank?

there is no monitoring on the in tank low pressure pump you would need to T into fuel line and measurecfuel pressure should be round 60 psi.


The di pump is mechanical pump fed from intank pump but im pretty sure it will just draw fuel through the in tank pump even if its low pressure or bot working

Can you give it a little squirt of starter fluid? If it "tries" to start you then know it's a fuel problem. If not then check your Flux Capacitor.

Got it resolved, found that the inline fuse on my Deatschwerks fuel pump hardwire kit was completely melted

That's a sign that something is terribly wrong, I would figure that out before hardwiring again.
