Fuel Pump Relay Replacement Cost (2026 Guide)

📈 Average 2026 US Cost

$80 - $250

Most relays cost $20-$60 and clip in under the hood. Some integrated modules cost $100-$200 and require coding.

📈 What Affects The Price

Relay vs integrated module: Older cars have a simple clip-in relay ($20-$50). Newer cars (post-2015) often have a fuel pump driver module that costs $100-$280 and requires coding.
Relay location: Under-hood fuse box is fastest. Some are inside the cabin or under a kick panel.
Diagnostic time: A proper diagnosis (swap-test with a matching relay) takes 15 minutes. Most shops charge 30-60 minutes of diagnostic time.
OEM vs aftermarket: OEM relays last longer but aftermarket Standard or Bosch are fine for $15-$40 less.
Whether coding is needed: Some fuel pump driver modules require BCM coding after replacement, adding $50-$100.
Dealer vs independent: For a simple relay, any shop is fine. For coded modules, prefer a dealer or scan-tool capable independent.

💵 Cost Breakdown: Parts vs Labor

🛠️ Parts

$20 - $180

Standard fuel pump relays are $20-$60 (Standard Motor Products, Bosch). Integrated fuel pump control modules run $100-$280.

👨‍🔧 Labor

$60 - $130

15 to 45 minutes if the relay is in the underhood fuse box. Integrated modules near the fuel tank take longer.

🎯 Total Job Range

$80 - $250

If the relay clicks but the pump does not run, swap the relay first - it is the cheap option.

🚗 Cost By Vehicle (6 Common Models)

Vehicle	Typical Range	Notes
Honda Civic	$80 - $160	Standard plug-in relay in under-hood box
Toyota Camry	$80 - $170	Similar to Honda, easy swap
Ford F-150	$120 - $260	FPDM module under driver-side frame rail on some years
Chevy Silverado	$110 - $230	Integrated module in some 2014+ years
Jeep Wrangler	$100 - $200	TIPM module is a known failure point
BMW 3 Series	$150 - $350	EKPS fuel pump control module requires coding

⚖️ DIY vs Shop Savings

🔧 DIY

+Relay is $20-$50
+Often a 5-minute clip-in swap
+Easy to test by swapping with horn or AC relay first
-Wrong diagnosis means you replace the actual pump too
-Coded modules require a scan tool
-Some relays are in hard-to-access locations

🏭 Shop

+Proper diagnosis with scan tool and multimeter
+Includes coding on integrated modules
+Warranty on parts and labor
-Some shops upsell a fuel pump instead of testing the relay
-Dealer pricing on coded modules can hit $400+

💰 Potential DIY Savings

$60 - $150

Excellent first-step DIY. Even if it does not solve the no-start, you have ruled out a $20 problem before spending $700 on a pump.

🔧 Difficulty & Tools

Difficulty Rating

2 / 10 (simple relay) - 6 / 10 (coded module)

Standard relays are a beginner job - pull the old, push in the new. Coded modules require a scan tool that can program new modules.

🔒 How To Avoid Overpaying

Before paying for a fuel pump, swap the fuel pump relay with a matching one (horn, AC clutch). If the car starts, you just saved $700.
Listen for the fuel pump prime sound when you turn the key to "ON" (before crank). No buzz = relay or pump.
Test for 12V at the fuel pump connector with a multimeter when cranking. No voltage = relay or wiring.
On Ford F-150 and Mustang, the FPDM (Fuel Pump Driver Module) under the truck is a common failure - it is not the pump.
On Jeep/Chrysler TIPM-equipped vehicles, the TIPM fuel pump relay is a known design defect - check for class actions.
Always check the fuse first - $1 part before any relay or pump work.

💬 Frequently Asked Questions

How do I know if my fuel pump relay is bad?

No fuel pump prime sound when you turn the key to "ON", long cranking before start, or random stalling that goes away after restart.

Can I test the fuel pump relay myself?

Yes - swap it with another identical relay in the fuse box (often the horn or AC clutch relay). If the car starts, the original relay was bad.

How long does a fuel pump relay last?

Typically 100,000+ miles. Heat soak from the engine bay and frequent high-current cycling are the main killers.

Is a fuel pump driver module the same as a relay?

No - it is a more complex electronic module that variable-speed controls the pump. Common on 2010+ Ford, GM, and BMW. More expensive and often requires coding.

Why does my car only fail to start when hot?

Classic heat-soaked relay symptom. The relay contacts open at high temperature. Park the car, wait an hour, and it starts again - relay is the prime suspect.

Will check engine light come on for a bad relay?

Sometimes a P0230 (fuel pump primary circuit) code is set. Often no code at all - the ECM cannot tell whether the relay or pump failed.
