Squash fuel system (fuel pressure sensor) - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Are you guys keeping the stock fuel pressure sensor? The directions from Squash seem to delete it. Or are you going with aftermarket in the A pillar or just using the analog off of the regulator?

Many use something like this, don't have the exact one handy:

Unless someone has figured this out, the sensor can no longer be used once you go with aftermarket dual/triple pump assm.

Damn i just bought a bunch of fitting to retrofitted on fore install. Wish i would known that.

Whats the reason it cant be use no more if you dont mind me asking?

it will work,but the FPCM will have to be connected and because the FPCM don't see the stock fuel pump anymore,it pops up the service engine light. I have my FPCM disconnected right now until I or someone figures it out to datalog or read it without the service engine light on.

Never going to happen. You must run an external sensor and gauge.

Lingenfelter has really nice Psi sending units,We have really nice small boost gauges that can also read fuel pressure ,just no datalogging. You could put a go pro on it during a run and go back and watch it.Or if you have a 5v input on you hp tuners cable or efilive cable or aeroforce gauge you could run it into one of those.

Our display sits right below the tach,technically you could datalog it.

If Andy didn't figured it out. I don't think nobody else can.

Stock sensor moved to the rail for logging, after logging I pull the fuse to the FPCM and the code p023f goes a way, only put the fuse in for logging fuel pressure for my tuner, FPCM used to power and read the fuel pressure sensor only, works just fine.

Pretty much what I have seen, but have seen it done with the fitting like above so the wiring doesn't have to be moved.

That's 1 option

It would be easier than to plug and unplug the FPCM .Haven't really thought about that.Yes that is the code that I see aswell
Where is this fuse located? the fuse box in the trunk ? I don't have the car in front of me right now.

In the trunk behind the right side carpet

I have the Squash Fuel system. I put a pressure sensor on my fuel rail and use that signal to one of the analog inputs to my SCT device. I datalog through that.
Setting up the transfer formula was a PITA, but after that all is good.
