I'm having a problem when the car is low on gas maybe 1/8 on fuel gauge it won't start unless i put more gas in the car. When this happens test gauge reads about 12 PSI when you turn the key on. I have changed the fuel filter, still reads 12 PSI Would appreciate any ideas as to whats going on. maybe bad fuel pump? Thanks, Bob DanD Veteran / Moderator Oct 11, 2005, 3:04 PM Post #2 of 4 (2391 views) Re: Fuel pressure Sign In Do you mean that your car wont start, your pressure gauge is showing 12psi, you add gas to the tank, the pressure goes up to the normal and starts??? If so that is very strange, the fuel pump pick-up screen doesn’t float with the fuel, it’s fixed as close as possible to the bottom of the tank. Dan.

Fuel injection needs more the 12 psi. The pick up for fuel is the same like he said so the fuel level shouldn't matter too much. The only thing I can think of is a low gas tank makes the fuel pump run hotter as they almost all recirculate and don't like being hot. It's a pain but keeping your gas tank near full can help prevent problems. - T mach8 New User Oct 12, 2005, 4:58 PM Post #4 of 4 (2360 views) Re: Fuel pressure Sign In Thanks guys for your response, changed fuel pump, everything is fine now.   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
