hello - yes, this could be the fuel pump failing, but could also be the fuel pump fuse(s) or relay (https://www.yourmechanic.com/question/-relay-keeps-getting-hot-and-turning-truck-off-by-luis-r). Either of these would cause the fuel pump to stop working, even if it was good. I recommend a...

Hi there: We're seeing more of these questions frequently with late 1990's Chevrolet's. Although there are multiple issues that could cause an engine to not start, the most common repair we're seeing is replacing the crankshaft position sensor. This component...

I wouldn’t condemn the head gaskets just yet. Intake manifold gaskets are a common failure item on your Chevy's engine. When they fail, they can leak externally, or internally, or both. When they leak internally, coolant gets into the oil....

Hello. If your car will not go into reverse, it is an indication that the reverse gear in your transmission has failed. This will prevent the truck from going into reverse. To fix this problem, the transmission will need to...

It is very possible that the fuel pump is going bad. Many times when the fuel pump fails this can cause the vehicle to die due to lack of fuel delivery to the engine. I would recommend having your fuel...

Depending on storage conditions, ethanol content, and so forth, fuel will expire in 2 to 6 months. If fuel has sat in a tank for 6 months, and the car has not been used during that period, there is no...

Fuel pumps rely on fuel for cooling and lubrication so be sure the tank is always kept at least one-quarter full of fuel. If there is a voltage drop on the supply circuit to the pump, that will cause high...

You need to have the fuel pressure regulator and injectors checked for leaking. The fuel pressure regulator (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-fuel-pressure-regulator) is most likely leaking into the intake and causing the excessive fuel to get into the cylinders. I'd suggest getting the vehicle...

Hello. Thank you for writing in. Looking to the spark system for a no start (https://www.yourmechanic.com/services/car-is-not-starting-inspection) situation. The screw driver trick is one way to test for spark. This is not the safest way to test, but does work. Once...
