Many 2011–2013 Jeep Grand Cherokee and Dodge Durango models, and other Chrysler vehicles of that era, have a fuel pump relay inside the TIPM (Totally Integrated Power Module) under the hood. When it fails, the engine cranks but won’t start, or stalls. Other TIPM faults cause random horn, wiper or light problems.
Quick answer: If your Jeep or Dodge cranks but won’t start, first listen for the fuel pump to prime when you turn the key on. No hum points to the fuel pump relay in the TIPM. Check your VIN for recalls: some 2011–2013 Grand Cherokees and Durangos had a recall that adds a separate fuel pump relay. Confirm with a fuel pressure test before replacing parts.

Wiring and grounds corroded connectors or grounds.
Before You Start
- Park on level ground, set the parking brake and chock the wheels. Never work under a car held up only by a jack: use rated jack stands.
- Let the engine and exhaust cool before you touch them; coolant systems are under pressure when hot.
- Wear safety glasses and gloves, and disconnect the 12V battery before unplugging electrical parts or working near airbags.
- Check for open recalls on your VIN (Transport Canada or the manufacturer’s site) before you buy parts: a recall repair is free at the dealer.
- Fuel is under pressure; use a proper gauge and relieve pressure before opening lines. No sparks or flames near fuel.
Step-by-Step: Jeep & Dodge No-Start
- Listen for the pump. Turn the key to on and listen at the fuel tank for a 2-second hum.
- Check your VIN. Ask a Jeep or Dodge dealer about open recalls for the fuel pump relay or TIPM.
- Scan the codes. Read codes; P0627 points to the fuel pump control circuit.
- Test fuel pressure. Connect a gauge to the fuel rail test port and compare pressure to the specification.
- Check power at the pump. At the pump connector, check for power with a test light during key-on.
- Check the TIPM. Check the fuses and connectors on the TIPM for corrosion or heat damage.
- Fit the repair. Install the external fuel pump relay kit, or replace the TIPM if it is at fault.
- Confirm. Start the engine several times and check fuel pressure again.
When to Stop and Bring It In
- There is power at the pump but no pressure: the fuel pump itself has failed.
- Several TIPM circuits are faulty.
- The TIPM needs programming after replacement.
- There is an open recall: let the dealer do it free. See car won’t start.

Frequently Asked Questions
Why does my Grand Cherokee crank but not start?
A common cause on 2011–2013 models is the fuel pump relay in the TIPM. Listen for the fuel pump hum and test fuel pressure.
Is there a recall?
There were recalls on some 2011–2013 Grand Cherokees and Durangos that add a separate fuel pump relay. Ask a dealer to check your VIN.
What is the TIPM?
The Totally Integrated Power Module, the fuse and relay box under the hood that controls many circuits.
Can a TIPM cause random electrical problems?
Yes. Horn, wipers, lights and the fuel pump can all act up.
Should I bypass the relay with a wire?
No. A jumper wire keeps the pump on all the time and is a fire risk. Use the proper relay kit.
Is it the fuel pump or the relay?
Check for power at the pump during key-on. Power but no pressure means the pump; no power means the relay or wiring.
