It's a 2007 Chevy Malibu LS can it be the fuel pump cost it not to crank or start


Bad fuel pump will not cause it not to crank, but can cause it not to start. Test with fuel pressure gauge. If it will not crank, entirely different issue=bad solenoid/starter, bad battery connections, bad ignition switch, relay,wiring.

My expedition 2001 eddie b it acts like iy isn't getting any gas we have boosted tried to reset fuel pump button but it wouldn't I guess its ok what is wrong what can we do?


You can spray carburetor cleaner in the throttle plate to see if it starts ! , if it doesn't try an start you need to check for spark ! pull a spark plug wire an stick a screw driver in the end of plug wire an hold close to metal on the engine an see if it gives a nice blue arc. Don't touch the spark or the metal of the screw driver , you won't like it an it could hurt you, a lot of volts 40- 60 thousand !!!!!!! On the other hand if it does try to start you have a fuel delivery problem. There is a fuel pump relay in the underhood battery junction box , you could test for power an control if you knew how ! An under the right side of the dash is the Inertia fuel shut off switch ! You could also test for battery voltage at the inertia switch. When you turn the key on the PCM - powertrain control module powers on the fuel pump relay for two seconds to prime fuel system . When cranking the engine over if the PCM sees a crank sensor signal the fuel pump relay is energized all the time while cranking. You could also jump the fuel pump directly at the relay socket if you knew how too do it ! How to Diagnose Bad Fuel Pump No Pressure Ford Ranger

Hard Start When Cold 01 Bucik Regal


Did you check the fuel pump relay ?
You would need to use a fuel pressure gauge and check pressure before you crank the engine.
When you turn the key switch on, the pump relay is supposed to provide power for 3 seconds to boost fuel pressure.
If fuel pressure is ok, the coolant temp sensor could be telling the computer the engine is warmer than it really is.

2002 lincoln ls fuel pump electrical cutoff switch


The inertia switch should be in the trunk behind the trim panels.
You may need a pump relay.

Hard cranking when engine is at operating temp, I have replaced the fuel pump relay, still having problem


If it is a "warm restart extended cranking", almost always it is low fuel pressure caused by a plugged fuel filter or a bad fuel pump, good luck!!

01-LS stops when idling/driving/hot/cold....


make sure to check for and aftermarket ignition module installation in other words make sure the ignition module is factory and not aftermarket,
this is not a fuel problem because fuel problem acts diferent
but coul be your ignition module or your crank sensor
