can anyone help me and tell me how to do a bottle test to see if i have to much fuel return on my injectors.
To check for high return use EFI-Live, Snap-on Modis, tech2 or similar to command 160MPA fuel pressure. If it does not maintain within 2MPA of commanded pressure suspect high return rate or faulty relief valve.
is that accurate? if you use a scan tool to try and check return the injection pump is still in the picture and could be faulty, the scan tool would just confirm you have an issue!
