Fuel Pressure Fundamentals For The Plymouth Acclaim

The fuel pump in a car is responsible for delivering gas from the fuel tank to the fuel injectors. The Plymouth Acclaim, a car model produced between 1989 and 1995, is known to have some issues with its fuel pump. Some common problems reported by owners of this model include the fuel pump not coming on, losing fuel pressure, and the car not starting or running due to a lack of power. It is recommended that the fuel pump is replaced if there are any issues, as driving with a faulty fuel pump can be dangerous. The cost of replacing the fuel pump in a Plymouth Acclaim can range from $528 to $563, including parts and labour.

Fuel pump issues

The fuel pump in a car is responsible for delivering gas from the fuel tank to the fuel injectors. The pump must deliver the right amount of fuel and at a high enough pressure to keep the engine running smoothly. If there is a loss of fuel pressure, it could be due to a faulty fuel pump.

Some common issues with the fuel pump in a Plymouth Acclaim include:

• The fuel pump not coming on: This could be due to a faulty relay or a problem with the wiring. It is recommended to check the fuel pressure first to ensure that this is the issue. If there is no pressure, then the relay and electrical circuit can be checked.
• Loss of engine power or the car not starting: A failing fuel pump will not create enough pressure in the fuel system, which can cause a loss of engine power or prevent the car from starting.
• Noise or leaks from the fuel pump: If the fuel pump starts to make a lot of noise or leaks, it may be failing and should be inspected as soon as possible.
• Check engine light comes on: A bad fuel pump can cause the check engine light to illuminate.

It is important to note that fuel pump issues can be dangerous and should be handled by a professional repair shop. Repeatedly running the fuel tank low or driving with clogged fuel filters can also put additional strain on the fuel pump, shortening its lifespan.

Fuel pump replacement cost

The fuel pump is responsible for delivering fuel to the engine from the vehicle's fuel tank. In modern gasoline vehicles, this is done via an electric fuel pump located within the fuel tank.

There are several signs that indicate a bad fuel pump. Firstly, you might notice that your car sounds different when it is on. Instead of a soft humming noise, you may hear a sharp whining sound from your fuel tank. Secondly, your car may have trouble starting due to the fuel pump's inability to maintain static pressure. A weak fuel pump can also cause problems with acceleration, such as hesitation, lack of power, or stalling. Finally, the fuel pump may fail completely, causing the vehicle to shut off and become inoperable.

The cost of replacing a fuel pump depends on several factors. The parts cost of a fuel pump typically ranges from $75 to $250, depending on the vehicle. If you choose to replace the fuel pump yourself, you will only incur the cost of the part. However, if you decide to hire a professional, the labour cost can range from $400 to $600, and the total replacement time can take between 1 to 6 hours. It is important to ensure that the fuel tank is properly cleaned of all contaminants during the replacement process.

In addition to the fuel pump replacement cost, there may be other related expenses. For example, a clogged fuel filter can exhibit similar symptoms to a bad fuel pump, so it is recommended to change the fuel filter first. Additionally, modern vehicle fuel pumps often include the fuel-level sending unit, so a malfunctioning fuel pump can affect the fuel gauge. In such cases, replacing the fuel pump assembly can rectify both issues.

Fuel pump location

The fuel pump in a car is responsible for delivering fuel from the tank to the engine, and issues with the fuel pump can cause the car to sputter and die, or not start at all.

The fuel pump location in a Plymouth Acclaim is inside the fuel tank. This is confirmed by a user on CarGurus.com who states that their 1992 Plymouth Acclaim stopped running and they were told it was the fuel pump. Another user on the same website confirms that the fuel pump is located inside the gas tank of their 1993 Plymouth Acclaim.

In addition, a user on 2carpros.com with a 1993 Plymouth Acclaim states that their car started, sputtered, and then died, and would not start again. They could not hear the fuel pump starting up when turning the key and wanted to know the location of the fuel pump relay.

It is important to note that the fuel pump relay is different from the fuel pump itself. The relay is an electrical component that controls the fuel pump, and it is usually located in the engine compartment, often on the driver's side.

To diagnose a potential issue with the fuel pump in a Plymouth Acclaim, it is recommended to check the fuel pressure first. This can be done by using a fuel pressure gauge to measure the pressure in the fuel lines. If there is no pressure, then the issue may lie with the fuel pump or the fuel pump relay.

Fuel pump relay

The fuel pump relay is a crucial component in ensuring the proper functioning of your 1992 Plymouth Acclaim's fuel system. Here's a detailed guide to help you understand and address any issues related to the fuel pump relay:

Location of the Fuel Pump Relay

The fuel pump relay in your 1992 Plymouth Acclaim is located on the driver's side of the vehicle. Specifically, it can be found on the fender well, mounted on the strut post, near the headlight. This information should help you easily identify and access the relay for inspection or replacement.

Symptoms of a Failing Fuel Pump Relay

• Inoperative Fuel Pump: One of the most common signs of a faulty fuel pump relay is that the fuel pump itself does not function. This can manifest as an inability to hear the fuel pump engage when turning the ignition key.
• Intermittent Functioning: In some cases, the fuel pump relay may exhibit erratic behaviour, causing the fuel pump to work intermittently. This can lead to starting issues and stuttering while driving.
• No Fuel Pressure: A failing fuel pump relay may cut off power to the fuel pump, resulting in a lack of fuel pressure. This will cause the engine to crank but not start, as fuel is not being delivered to the engine.

Troubleshooting and Replacement

When facing issues related to the fuel pump, it is essential to first check the fuel pump relay. This can be done by measuring the voltage at the relay and inspecting for any signs of damage or corrosion. If the relay is faulty, it should be replaced with a new one. Additionally, it is recommended to check the fuel pressure and the entire electrical relay and wiring control circuit to pinpoint the exact cause of the problem.

Preventative Maintenance

To avoid unexpected fuel pump relay failures, it is advisable to regularly inspect the relay for any signs of wear and tear. Ensure that the battery is in good condition, as a weak or old battery can cause undervoltage conditions that may impact the fuel pump relay's performance.

Fuel pump specs

The fuel pump in a car is responsible for delivering gas from the fuel tank to the fuel injectors. The pump must deliver the right amount of fuel and at a high enough pressure to keep the engine running smoothly. Fuel pumps on most cars and trucks use an electric motor to drive a fluid pump. The pump can be either inside or outside the fuel tank.

The fuel pump specs for the Plymouth Acclaim are as follows:

• The average cost for a Plymouth Acclaim Fuel Pump Replacement is between $528 and $563. Labor costs are estimated between $132 and $167 while parts are typically priced around $396.
• The fuel pump is located inside the gas tank.
• Walbro OEM Fuel Pump Kits are available for the 1991-1995 Plymouth Acclaim with a 4-cylinder 2.5L engine, the 1991-1992 Plymouth Acclaim with a 4-cylinder 2.5L Turbo engine, and the 1991-1995 Plymouth Acclaim with a 6-cylinder 3.0L engine. The kits are priced at $299.99 and guarantee fitment.
• Fuel pump issues can be diagnosed by checking for pressure at the fuel injectors when trying to start the car. If the pressure is low or non-existent, the pump's electrical circuit should be checked.
