Fuel pressure is typically in the 35 to 45 psi range. If your Anti-Theft light is flashing; the anti-theft system is disabling the fuel pump to prevent the engine from starting. Bad fuel pump (Pump should run for a few seconds when ignition key is turned to start, no buzz means no fuel delivery to the engine).
Can a weak fuel pump cause a car to not start?
A weak fuel pump may still pump fuel, but the vehicle may experience difficulty starting from the lack of pressure. A weakened fuel pump can cause the vehicle to take more cranks to start than normal, and in more serious cases may even cause the vehicle to require multiple turns of the key before it will start.

What is the diagnostic code for fuel injector problems?
The injector can face problems due to a contamination of the inlet filter on the injector. It is also possible for this problem to arise because of a dirty or clogged fuel filter or a defective fuel pump. P0253 is widely known as the diagnostic trouble code for “Injection Pump Fuel Metering Control A Low (Cam/Rotor/Injector.”
What are the symptoms of no fuel pump?

What causes fuel pump code p1614 to fail?
The most common cause of code P1614 is failure of the fuel pump relay. Other possible causes could include the following- Failed, or failing PCM. Note that this is a rare event, and the fault must be sought elsewhere before any controller is replaced. What are the symptoms of code P1641?
Why does my fuel pump not start when I change it?
You always want to replace the fuel filter when replacing the fuel pump. This could cause the concern you are having.

Why does my Chevy Spark Plug not start?
Chevrolets have a common issue with fuel filters getting clogged. You always want to replace the fuel filter when replacing the fuel pump. This could cause the concern you are having. It may seem as you are getting enough fuel from the pressure regulator but if the pressure from the fuel tank is not correct, it will still not start.
How to diagnose a faulty fuel pump in the garage?
Perform a thorough diagnosis to ensure the pump is the problem before replacing it. The first step is to verify the problem is fuel related. Then, you can do additional testing to find out if the pump is to blame. Listen for the fuel pump: Put your ear near the fuel tank and have an assistant turn the ignition key to the “on” position.

That’s the sound of the fuel pump being energized. That means the pump is receiving power and it’s responding. If you don’t hear this sound but the engine cranks when you try to start it, you may have a problem in the fuel pump electrical circuit.
Where can I find the fuel pump code?
The codes may either be directly related to the fuel pump or make reference to an air/fuel ratio problem. A scan tool or a simple code reader can be used to retrieve the information. Many auto parts stores will pull codes for free. Plus, there are inexpensive code reading tools and apps for your smartphone.

Where is the fuel pump control module located?
It is often found in the fuse box located in the engine bay and functions as the primary electronic switch that controls power to the fuel pump. The fuel pump relay is usually controlled by the ignition or Powertrain Control Module, and when switched on, will provide current to the fuel pump so that it may function.
What does p0628 fuel pump a control circuit mean?
Although generic, the exact repair steps may vary depending on year, make, model and powertrain configuration. If the P0628 code appears, it means that a problem has been found in the fuel pump “A” control circuit. Specifically it means that a low voltage situation has been detected.
What are the symptoms of a bad fuel pump relay?
A bad fuel pump relay can cause many different symptoms. Here are the most common ones The fuel pump relay is an important component of the fuel system of your vehicle. The fuel pump relay gives the fuel pump power when it is time to build up fuel pressure in the rail.
What is the code for the fuel pump control module?
The codes were P3089 and more specificaly, it said “P025C fuel pump control module, short to ground”. Ross Tech says; Check/Replace Transfer Fuel Pump (G6).
What are the symptoms of a fuel pump relay problem?
1. Engine stalls One of the first symptoms of an issue with the fuel pump relay is an engine that suddenly stalls. If the fuel pump relay has an issue while the vehicle is operating it will cut off power to the fuel pump, which will cause the engine to stall.
What is the code for the fuel pump on an Audi A4?
I’m trying to diagnose a P0089 (VAG P310B) code on my 2007 Audi A4, not your specific situation but similar.

Where can I get a fuel pump gauge?
Because GM has installed a Schrader valve on the fuel injector rail that facilitates checking the fuel pump with a fuel pressure test gauge. Don’t worry, a fuel pressure test gauge is not inexpensive diagnostic tool and you can pretty much find one (to buy) just about anywhere (AutoZone, Pepboy’s, O’Reilly Auto Parts, etc).
How can I Check my returnless fuel pump?
A digital multimeter (DMM) can be used to check the circuit for continuity, power and ground, as well as any unwanted excessive resistance. Check the fuel pressure regulator: Returnless fuel systems do not have an external pressure regulator.
