Homer Posted February 11, 2006 Share Posted February 11, 2006 I can't find any instructions on here for checking the fuel pressure on an Aeromotive FPR. Anyone got any links or tips? Cheers Link to comment Share on other sites More sharing options...
BURT Posted February 11, 2006 Share Posted February 11, 2006 have you not gpt a guage that goes on the side of the fpr? Link to comment Share on other sites More sharing options...
Alex Posted February 11, 2006 Share Posted February 11, 2006 Put the small gauge on the front (if it's not already) Start the engine, pull off the vacuum reference line. Note pressure, adjust if needed, put hose back on. Personally I left the pressure gauge on all the time.... Link to comment Share on other sites More sharing options...

Static fuel pressure should be set without the engine running. What you need to do is run the fuel pump with the engine not running and check the pressure. To do that you connect the +B and FP pins on the diagnostics port in the engine bay and turn the ignition on. Link to comment Share on other sites More sharing options...

Soonto_HAS_soop Posted February 11, 2006 Share Posted February 11, 2006 Go with Simons method. Link to comment Share on other sites More sharing options...
Alex Posted February 11, 2006 Share Posted February 11, 2006 Ahh forgot - yes - I couldn't do that (proper way) with the VVTi as there is no way to prime the pump unlike the previous versions. The FP pin isn't on the diag box for the VVTi. Link to comment Share on other sites More sharing options...
