    2002 nissan pulsar n16 help

    So im looking at the above car for a neighbour .

    Backstory : Car has sat for 2 years . Apparently car ran fine when parked up 2 years ago. Went and took a look and car would start run for 5 seconds then stop. Clamp off fuel return line car would continue to run (although poorly)
    I checked fuel pressure directly at the outlet of the pump and only had 20psi. Bought and fitted a new pump and yay , 90 psi at pump outlet , ~40 psi regulated.

    Car did exactly same thing , ran for 5 seconds then stopped. i suggested maybe the injectors.. because his funds are limited , he decided to try some fuel system cleaner along with fresh fuel in the tank. he kept the fuel return line clamped and ran the car for 20 minutes , which afterwards he could remove the fuel return line clamp and the car would continue to run (although still poorly).

    I went and took a look at the car the following day. Once again it would start , run for 5 seconds then stop (from cold). i did the same as he did , start the car with fuel return clamped and warmed it up to the point i could remove the return line clamp and car would continue to run. tried revving it up and it will not rev past around 3000 rpm.

    There is no check engine light on and i am unable to scan the ecu (my scanner only does suzuki and toyota)
    i put a noid light on it and it is cutting injection.


    Ideas Gents?

      The filter was part of the in tank fuel pump assy to buy the filter was nearly $500 , i used a generic bosch fuel pump which was a direct plugin to the original socket (efp-007) .

      i checked the fuel pressure directly out of the fuel pump sat in the tank and was only getting 20psi from old pump so knew it was the pump not the filter . after replacing the pump in the in tank assy , i checked the pressure AFTER the filter and was getting 90 psi and 40 regulated.

        Throw a CAS on it, these things always used to kill them even when brand new.

            Iíve only even seen that fuel cut type behaviour when the tps is stuck reading zero

              Yep mate of mine said that was the case and he has some test units he can loan me to try

              tested that and with a fuel pressure gauge tee'd in its getting 40 psi .

              hmm if the tps was stuck reading zero would it not still start and idle fine ?

                Is it maintaining the 40psi of regulated fuel pressure when you rev it to 3000?
