Thread: My Car Keeps Cutting Off!

Recently my car has been acting up, and losing power at high rpms... when the car is low on gas it shuts off completely.. I have...

calum basic

im doing a full tune up on the weekend but does anyone have any suggestions?? (i already replaced the fuel pump.)

You replaced it with a stock fuel pump or a 255lph-hp pump? Did you try replacing the fuel filter? They're only like $4 may as well try it.

you may double check fuel pressure...

How low on gas are we talking.

If you have a Walbro pump your car is also running rich and you will need a Nismo fuel presure regulator adjust the fuel presure back to its original setting. The presure you are looking for is 44 PSI with the vacume hose off of the FPR or about 36 PSI with it on.

Does you car seem t shut off when you go into a corner also. If that being the case the fuel pump box in the tank was not put back properly and it is either leaning to the side or it is now floating around in the tank. I have seen this happen a few times.

There is also a return line that goes back to the box if that was not put on, or came loose the gas coming back from the motor will not refill the pick up box and it will run dry.

what he said ^^^

after goin thru all that **** it turned out to be the maf.. since then i gota new one and now it runs beautifully
