Staying on Top of Your Chevrolet Blazer Fuel Gauge
A malfunctioning fuel gauge may not sound like a big deal or seem like a threat to one\'s safety, but it sure poses other issues, such as possible underlying problems that have caused the gauge\'s erratic behavior in the first place or the total untrustworthiness and unreliability of the fuel reading. Having a malfunctioning fuel gauge could not only be troublesome but also give way to other complications. So instead of simply shrugging it off, why not stay on top of the problem and work out other issues that may compromise the overall performance of your Chevrolet Blazer.
Common causes of fuel gauge failure
Your fuel gauge doesn\'t just fail on its own. The usual culprit behind its incompetency is actually the fuel level sensor inside the fuel tank, which fails and consequently provides the gauge wrong information. On some occasions though, it may be the fuel pump or worse, the powertrain control module itself, which is responsible for the fuel pump speed and the fuel pressure. A problem in the electrical system or a bad relay can also cause the fuel gauge to fail. Whatever it may be, you can\'t provide a more permanent solution to the problem if you can\'t correctly pinpoint the root of the issue. So make sure that you know what exactly caused your fuel gauge to fail in order for it to be properly fixed.
Signs that your fuel sensor is failing
First thing you\'ll notice would be the Check Engine light turning on. It\'s a common behavior for motorists to ignore the Check Engine Light especially if they think that they\'re running smoothly. Well, that\'s actually the tricky part; the Check Engine light turning on doesn\'t say anything else other than an issue becoming present. It could be minor,or serious, and the only way to be sure would be to find the source of the problem. Yes, it could be a lot of things, and it doesn\'t necessarily mean that your fuel sensor is failing, but on the other hand, it could exactly be the problem.
Preventing total fuel gauge breakdown
The quickest way to avoid having a fuel gauge breakdown or to experience it again would be to replace the entire fuel pump module. Unfortunately, this could also be very expensive. You can try going to the root of the problem, which is the fuel level sensor failure. Make sure that the connections are all working properly and that the sensor had not been damaged. A faulty crankshaft sensor can also contribute to the problem as it is responsible for determining when the pump should be activated. While on the other hand, the camshaft sensor tells the computer where top dead center is and determines when the fuel should be delivered to the cylinder. If these sensors are malfunctioning, then the fuel delivery system gets compromised.
Sensors are vital to your vehicle\'s fuel system because without them, the Power Control Module (PCM) doesn\'t really have something to go with. The PCM wouldn\'t be able to correctly make critical decisions and in turn may lead to more than just a fuel gauge breakdown.
