1988 300zx turbo
low fuel pressure problem - running rough, stalling, loss of power
1. code 42 - fuel pressure regulator
2. swapped fpr from an 88na. After the swap still got code 42 and still no pressure. Also, "possible problem" fpr worked fine in 88na after swap, so both fpr's working ok. rule out fpr (Peculiar--->(when removing good one from 88na, fuel sprayed everywhere for a quite a while....but when removing the "possible problem one" from the turbo there was no pressure)
3. I think I got (code 42-fpr) because the fpr at least needs pressure to work
4. I can hear fuel pump running.
5. AFM clean burn test ok
Need help.........THANKS!!!
