2014 Caprice 408 swapped lots more, but I hope to learn about fuel pressure info.
I have Fore innovations dual pump, with their controller installed, and now a return system with mechanical regulator for adjusting fuel pressure.
I pulled the fuse from the FPCM due to codes, but here is my question:
The fuel pressure sensor is plumbed in the system, but wired to the stock FPCM so now the ECM has no signal.
Should I reconnect the FPCM and deal with the codes generated due to no pump connected?
Is there a solution to connect the pressure sensor to the ECM direct?
Is this pressure signal needed?
Thanks to anyone who has taken time to read this.
