Fuel Pressure Dampener?
Here's what i have done and specs
SR20VE P11 in B13
Infiniti G37 Fuel Pump
Cleaned Tank and in tank filter
fuel pump replaced 3 months ago
Fuel Filter replaced 3 months ago
Spark Ignition components checked and good
checked fuel pump relay and fuse
Pulled Fuel rail with injectors checked resistance on injectors at 13 ohms
Here's the issue, cranks wont start, Fuel comes out of the line from fuel filter into feed line, no fuel (bone dry coming from FPR which connects to return line) during ignition on or when cranking
when i relieve the pressure and pull the FPR and turn ignition on to fill up the rail with fuel, starts and idles til the rail runs out of fuel and dies after a few seconds
replaced the FPR with a known working FPR from a VE and DET and still the same issue, so that eliminates the possibility of a bad FPR
here is what im thinking, would a Fuel Pressure Dampener not be able to let fuel through the rail when i reinstall the FPR
test i have done is, turn ignition on with the fpr removed and fuel pours out where the FPR sits, pretty strong, do FPD's go weak over time? and with the FPR installed the FPD just doesnt have enough to let fuel through?
checked and replaced vac lines for both FPD and FPR (intake manifold is clean)
been doing searches and reading on similar situations as mine, and most peeps just replace the fuel rail but never really isolate the issue to either fpr or fpd
