Running Rich With Stock Fuel Pump - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

180sxsun · 12-18-2006, 04:59 PM

Can someone help me out! I recently took out the walbro fuel pump and put the stock one on, the car was running really rich thats why I put the stock back on, now it seems it made a difference but i still see black smoke coming out (not a whole lot), and my gas goin down fairly fast, could cams cause this problem or is there a place I can control (VIA MOTOR) the flow of gas?

Caps lock will get you flamed here at Zilvia. Or ignored if you're lucky.

Edit: Sorry I can't be of more help to you. Just a suggestion that you may want to edit your post a little. ;D

oil change or tune up, maybe?

mandoz85 · 12-18-2006, 06:37 PM

maybe one of your injectors is leaking, causing you to run rich? check your fuel pressure regulator, timing and do a tune up.

okay.

i'd start with the visual inspection to see if there's any fuel leaking. when you don't find anything, i would go with the tune up.

thanks for all the info ill do my best to check everthing out, and one more thing just to throw it out there, could the maf also be a factor?

engine light on? maybe you should reset your ecu..

Markovich · 12-18-2006, 07:28 PM

coolant level good? is you coolant sensor for the computer good? that will cause it to run rich. also a bigger fuel pump wont make your car run rich unless your regulator is bad...

peace

yea grab a fsm and follow the steps to check your fpr, also check your maf, and go ahead and check your spark plugs, because they might be fouled now since its been running rich
