Why does my Dodge Omni stall after a few minutes of driving?

Short answer: On a 1988 Omni 2.2 that stalled within the first 10 minutes of driving, the fix was the Hall effect pickup in the distributor, which a member called a common ignition failure on Chrysler 2.2 and 2.5 engines. Others had suggested a weak fuel pump or the injector relay. If yours sputters when the choke comes off and smells of gas or drips fuel, check the fuel tank vent and vapor lines are routed to the right places.

Symptom: Within the first 10 minutes of driving, the engine stalls, no matter how much fuel is in the tank. Or it sputters when the choke opens, smells of gas and may drip fuel.

What to check first

1. When it stalls, check for spark. No spark points to the distributor pickup.
2. Have fuel pressure tested to rule out a weak pump.
3. Check the injector relay (one member suggested a jumper test).
4. Look for fuel leaks or drips and smell for gas around the tank and lines.
5. Compare vapor line routing to a diagram; a disconnected vent line was found on one Omni.

Likely causes

1. Distributor pickup (Hall effect) plate. The confirmed fix on the 1988 Omni.
2. Weak fuel pump. Suggested as intermittent before failing completely.
3. Fuel injector relay affected by heat. Suggested for the 1988 TBI engine.
4. Vent or vapor line problems. Suspected for a 1988 that sputtered and smelled of gas.

What it usually costs

No owner posted prices.

Is it safe to keep driving?

Stalling in traffic is dangerous, and a gas smell or drip is a fire risk. Don't drive it while it leaks fuel. Verify with a mechanic.

DIY or shop?

DIY for the pickup plate, relay and line routing. Fuel pump work is usually shop work.

• Plain words: Recall 84V116000 covered an emissions valve on 1985 Omnis that can make the mixture too rich and cause stalling while stopping, coasting or turning. That's close to this problem. Other recalls (84V147000, 85V010000, 88V105000, 91V132000) covered fuel leaks in the engine bay on mid-1980s models. If you smell gas under the hood, don't drive it until it's checked. Verify with a mechanic.

What owners report

• In 1988 Dodge Omni stalling issue on Car Talk, a 2.2 TBI Omni stalled within the first 10 minutes of driving regardless of fuel level. Members suggested a weak intermittent fuel pump, a fuel injector relay affected by temperature, and replacing the distributor pickup plate, which one called a common cause of ignition problems on Chrysler 2.2 and 2.5 engines. The owner reported back that the Hall effect pickup was the problem, and the car went back to daily driving.
• In My poor Omni on Car Talk, a 1988 2.2 Omni wasn't getting enough fuel and sputtered when the choke came off, smelled of gas and sometimes dripped fuel. The owner found a tube that wasn't connected to anything. Members suspected a fuel tank vent line and shared the evaporative line routing so the owner could check where each line should go.

Quick tip

If your Omni stalls with no spark, the distributor pickup is the first part to suspect. If you smell gas, fix that first.

Vehicle focus: 1978–1990 Dodge Omni (2.2L four).
