Fuel Pump Info

okay, i dropped my Walbro 255 fuel pump in yesterday. my plan was to drive the whip to get dyno tuned, but when i started the car it ran for a few minutes then died out. i know its because its extremely rich for a stock ecu, but even with smaller injectors the car continues to turn over and over. is there any hope of getting the car to start, or should i just tow it to the dyno and work from there. note: i have an p28 ecu that has a base map for 550cc injectors, but i did not put it in for fear of the same problem i ran into today. i have F22B Vtec injectors, F22a4 non-Vtec injectors, 550cc injectors, a stock ecu, the basemapped ecu mentioned before and the fuel pump. if there is a combo that i can put together to get the car from point A to point B, please let me know.

1. Your going to get flamed for spelling vtec wrong. Please learn to spell it right really not hard.

2. Find another map. What are your mods. 550cc vs 240cc or whatever stock is is a big difference. Find a basemap that is close to what you have.

3. What are your mods anyway.

good lookin out. fixed the spelling error. feel like an idiot now. okay. all the upcoming was on the stock ecu: i ran the stock fuel pump with 550cc injectors and the car ran rich, but it was driveable. i put the stock injectors back in and upgraded the fuel pump to the walbro 255 and now the engine STAYS flooded.

as far as mods, its SUPPOSED to be a boosted F22B SOHC VTEC, with the injectors and fuel pump. thats IF i ever make it to the hot damned dyno

stock ecu(p0A), stock injectors.

stock ecu(p0A), stock injectors.

im guessing go back to the stock fuel pump as well? cuz the stock ecu/stock injector with the upgraded fuel pump idea didnt work either.

you must have messed up something during the fuel pump install.

it should work with stock injectors/ecu and the walbro pump.

but it WAS working. the car was running, i even revved it up a few times just to make sure fuel was being circulated. i turned it off, ran a few errands and two hours later, the car started up again, and then died out all together.

well, i pick up my fuel pressure regulator Friday. i am hoping i can throw my 550s in along with my fuel pump and just lower the fuel pressure. if that doesnt work, then i have a SERIOUS problem. by the way, does anyone know the size of the stock fuel pump for the 90ex sedan?

the FPR's functionality should make the car work fine with the 255. any extra pressure gets fed right back to the tank... you have a different issue than the pump...
