You can run a compression test on the cylinders to check the head gasket. This is to remove the fuel line that connects to the fuel injector rail and place it in a container. Every application is different, so always look up the pressure specs when troubleshooting fuel-related performance problems. If you're asking if it has a safety feature shutting it off in an accident, no it does not, except if the engine shuts off due to the accident, fuel pump will not work, unless key is turned off and then back on, and will then work for about 5 seconds and shut off, unless engine is started.
If pressure drops quickly, the vehicle may have a leaky fuel line, a leaky fuel pump check valve, a leaky fuel pressure regulator or one or more leaky fuel injectors. If pressure at the engine fuel rail is even a couple pounds less than specifications, the engine may not start or run well, or experience hesitation or stalling problems.

There are no rules of thumb. While I am able I will make as many of these in what I feel are important subjects.

Dead Head Pressure This checks the maximum output pressure of the fuel pump.
My vehicle is the z-71 version of the Chevrolet 1500 pickup truck. The second to the last failure caused a domino effect that ended up being very costly to me. Checked ground, volted, replaced relay, pressure regulator. This time it luckily did not ruin the above mentioned items. Low fuel pressure creates a lean fuel condition that can cause lean misfire, hesitation, rough idle, hesitation and misfire on acceleration. Decreased level of driving quality, poor general performance, suboptimal gas mileage, or exposure to possible unit failure are just some down sides of driving a vehicle with a defective component. Ask our knowledgeable staff any questions about your installations and repairs.
This new fuel pump module assembly is ideal for your restoration needs at an affordable price. For more information, go to.
