fuel pump problem? please advice
Hello, ive got SR20VE swaped N15 with DE fuel pump.
I have floored it in first gear to 8k rpm and suddenly rpms went down to 0 and engine wont start, there was no strange sounds, starter is running, only difference is, that i cant hear fuel pump buzzing anymore.
Another thing is, that i am encountering strange engine behaviour. I am running without O2 sensor and downpipe only. Thing is, that sometimes after revving up the engine, RPMs are going higher, even when de-clutched.

Thank you. ADR

get a o2 sensor and sounds like you need a new fuel pump.check the fuses,and the voltage at the wires than connect to the fuel pump..let us know what happens.hope fully your engine didn't mess up..

thank you for response.

so, dont have fuel pump yet, but i've tried voltage on FP connector and its 11.94V first 2-3secs after turning ignition to second position. If i am right, this is another fact, that problem is in fuelpump.

i've tried to fault check my ECU and i am getting code 21, something wrong with ignition signal. Can it be somehow related? Fault check was done with cold engine and fuel pump disconnected.
