Hi There,
It sounds like you may have a fuel line running to or from the pump that may be leaking. As you know, this can be very dangerous and should be looked at as soon as possible to avoid a potential fire. Depending on the location of the leak, this may be related to the fuel pump installation or it may be unrelated. I would suggest having a professional from YourMechanic come to your location to take a look at your Blazer to determine how to properly repair this.

How to Identify and Fix Common car Problems ?

You are smelling gas because there is a gas leak. Fuel leaks are the #1 cause of engine fires. The only option is to find the leak and repair it.
The most likely causes of this are leaky hoses inside the tank. Some fuel pump modules use clear corrugated flex hoses inside the tank. This hose is designed to stand up to fuel and can reduce noise from the fuel pump.
Check all the connections (fuel lines and wiring). If you have a fuel pressure gauge, test the pressure—it`ll almost certainly be low. You can also try removing and reinstalling the pump, following the installation procedure carefully. If the issue persists, you likely have a defective part.
When you were installing the fuel pump module back into the fuel tank you may have inadvertently bent or damaged the the fuel gauge sending unit. If the sending unit arm got bent when installing it then it will bind up on the metal anti slosh plates inside the fuel tank.
1 Answer. You shouldn`t have to reset the ecm after changing the fuel pump.
If a fuel pump isn`t installed correctly, it either won`t work at all or won`t supply enough fuel to the engine. When the fuel pump isn`t working right, your engine isn`t getting the amount of fuel it needs to run well. Your engine loses power and fuel efficiency.
A leaky fuel line will produce either drips, or in more serious cases puddles of fuel underneath the vehicle. A leaky fuel line will also cause a drop in fuel pressure, which can compromise the operation of the fuel system, which can cause engine misfires and stalling.
Once the vehicle determines the systems are safe, then the vehicle allows you to restart. The fuel pump shut-off switch is located behind an access panel on the right side of the luggage compartment. The fuel pump shut-off switch has a red reset button on top of it.
Press and hold the “Trip/Odo” button again until the Odometer says “1.” This means that the reset process has begun. Keep holding the button down while the fuel gauge resets. Release the “Trip/Odo” button once the reset is complete. You`ll know the process is finished when the Odometer display moves back to normal.
Cracked Charcoal Canister
If your car smells like gas, but there`s no leak from the gas tank or fuel lines, it`s time to turn to other possibilities. The charcoal canister is a key part of the EVAP (or evaporative emissions control) system in your vehicle.
If your engine is burning too much gas, it will increase the amount of gas fumes coming out of your exhaust. When there are more gas fumes coming out of your exhaust, it`s possible that these fumes will make their way into your ventilation system, which is why you would smell gas inside of your car.

Fuel pump not pumping gas. 1996 Chevrolet Blazer
ANSWER : Hey there, thanks for writing in about your 1996 Chevrolet Blazer. If you hear the pump, but still get no fuel out of the pump, then you have the power and ground backwards in the wiring or they have it backwards on the pump. If you need help having this checked, a certified professional from YourMechanic can inspect the starting issue and let you know what repairs are necessary.
Just replaced my fuel pump but its not getting any power tested fuel pump relay and fuel fuse both good tested the wires all good.
ANSWER : You need to look at the theft light on dash to make sure it comes on and goes off when you turn the key to the on position. If light comes on and stays on then your theft system is causing the fuel pump to not be engaged. I recommend you check the theft system and then scan the computer for theft system codes. You may need to reprogram the keys to work or you have an bad sensor for the ignition key in the steering column.
the car is acting like its getting to much fuel. changed the fuel pump, fuel filter, and the fuel pump relay.
ANSWER : There could be a few things contributing to your problem. You are correct that clogged or sticking fuel injectors and possibly the fuel pressure regulator could be faulty. A plugged catalytic converter can also cause the vehicle to bog down. A failing throttle position sensor can cause the symptoms you describe as well. I suggest having a certified technician, like one from YourMechanic.com, do a few tests to determine the exact cause of your starting concern.
Cranks and runs rough have to keep foot in gas to keep running. Has new fuel pump and died while driving after pump was changed
ANSWER : Check fuel pressure. There are only three possible explanations: a fault in fuel supply (plugged filter, injectors, etc.); ignition system problems; and air induction including the idle air control valve, throttle position sensor, mass air flow sensor and vacuum leaks including the PCV and EGR systems. If obvious, and easy to check, possibilities do not reveal the fault, the recommended service to request is a rough running diagnostic and the responding certified mechanic will travel right to your location and get this diagnosed and resolved for you. It is also possible that diagnostic trouble codes have set and the mechanic will attempt to retrieve those using an appropriate scan tool. If you have further questions or concerns, do not hesitate to re-contact YourMechanic.
I have a truck that won’t run and is not getting gas to the engine. Fuel pump is running, have a new filter and new fuel pressure
ANSWER : Hi There,
It sounds like you may have a clogged fuel injector or potentially a faulty injector that is fried internally. I would suggest testing them if you have access to a multi meter. Disconnect the injector from the electrical connector and set your multi meter to Ohms mode and measure the resistance of the injector. After testing all injectors, compare the resistance. They should be the same or very close. If they are not, they will likely need to be replaced.

Installed new delphi fuel pump and fram fuel filter. still no pressure on fuel rail valve and wont start. 2003 Chevrolet Tahoe
ANSWER : Hi there – I suspect you have weak power getting to the fuel pump. I would first check the voltage coming out of the fuel pump relay. If the contacts in the relay are burned, you will not get reliable current flow to the pump. Check the fuel pump ground as well (voltage drop across the ground, not just continuity). I recommend a fuel system inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
Engine crank, no coil spark, fuel pump does not kick in.
ANSWER : Hi there. There could be multiple issues causing your lack of spark problem, ranging from a minor electrical short in the main relay to an issue with your ECU. In order to know for sure, you should have a professional mobile mechanic complete an electrical problems inspection.
