i have a 95 240sx stock.
no mods..
injector flooded out the 1st cylinder. i replaced with a functional injector. replaced all o ring. i pulled out the fuel rail as well.

to check if all injector are fuctioning...
- i put the key on ON position. just to make sure its not leaking.. or injector stuck open...
all injector was good no leak..

i checked all grounds everything was good...

i started right up.. right when i hit the trottle.. the car dies..

can you identify what i didnt do or what i missed ?

please reply
thank you

the car currently turns on.. but is on limp mod...

just wondering if anyone know how to take it off safe mode

UPDATE... i reset the ecu and is out of the limp mode...

but my problem is still here...

when i start the car it will idle for 10 sec or less.. then it will cut out.
when i try to step on the gas it will cut out.

maf is cleaned.. maf wires are checked.
timing is at TDC.
injectors is not leaking when i put on ON position.
grounds are all checked. and cleaned.

if you any can think of something please reply thank you..

did you reconnect the vac line on the fuel pressure regulator? are the fuel lines installed backwards (aka return and feed lines reversed) if they were disconnected during service? did you pull the fuel pump fuse or remove the gas cap to relieve the pressure?

just some things to check.
