Product Questions & Answers
Customer Guides
Are the codes P069E and P0231 code readings mean fuel pump problems when they appear in the scan tool that is plugged in a GMC Sierra 1500?
Most likely, the problem is coming from a damaged fuel pump control module. The truck may be driven and used normally even if this component is just on the verge of failing. However, immediate replacement is very important to avoid engine stalls and low acceleration rates. The fuel wires must also be checked for any short circuit and ground issues. The wires must be repaired quickly by soldering or by applying electrical tape.
What is the normal PSI reading to know if the fuel pump is still in well-performing condition?
If the fuel pump in a GMC Sierra 1500 is still in good condition, which means it's not leaking or damaged, the normal psi level seen on the truck's dash is around 50-60. The best way to know this is through conducting a test by connecting a fuel pressure gauge to a plug or port located on top of the engine. This analysis must be done with the key on the port, but the engine is off.
What is the proper way to wire a newly-installed fuel pump?
Connecting the wires in a new fuel pump is very easy. The colors of the fuel lines or cables in a GMC Sierra 1500 are different from one another. First to attach are the black and white wires attached to the fuel pump. These wires must be hooked up with the black wires that are already fixed in the truck. The remaining wires must be joined together according to their respective colors.
What is the right amount of voltage in the pump to make the car start? The readings say five volts. Is that normal?
Five volts is not enough. The power around the fuel pump and the grey wire attached to it should be 12 volts. Make sure to crank the engine while conducting a power test on the pump and wire.
