Wallbro fuel pump Hi all, i am new to this forum, as i have learnt so many things from this page. I have an issue hoping to resolve through this page if possible. The thing is i have replaced my stock fuel pump to wallbro 250 high flow fuel pump. As mine stock pump was playing up and one day it ended not working so replaced to wallbro. My car is r33 s2 97 all stock. Well, i called one of mine mechanic freiend to install it for me as i have no idea to install. As far as i know he just replaced the pump used the same wiring as the stock. And performances is fluctuating. When i fill the tank to the max the car lags the power and tend to go power cut and need to re start again and even if the fuel is about the quater happens the same. If i take sharp turn to left or right power tries to cut off. Called my mechanic friend explain it to him he has no idea. I just bought it 3 months ago havent enjoyed it yet. any idea regarding this issue. I know some brother will help this brother for sure...

Hi everyone, I'm seeking advice with a fuelling issue. My fuel tank had a leak and i took my car(1990 r32 gts-4) to a mechanic to get it fixed up. He fixed the leak and replaced my lines since they were old and cracking. When driving home, when coming to a stop my car would just drop to 0rpm and stall. I took the car back to him and he said i had a bad fuel pump and replaced it. I got my car back, but now my car was idling at 1400-1500rpm. I got home and saw that he had unplugged my TPS, and so it was just going on the fall back system and idling around 1500rpm. After plugging the TPS back in, the car had the same fuel pressure issue. I put a fuel pressure gauge in and when turning the ignition on, the pressure goes up to around 50psi. When i start the car it backs off a bit, down to around 35psi and then just slowly drops to zero and stalls. Does anyone know what this guy could have done or has anyone had this problem before? Just looking to know what I should be checking first.
