Ran fine ween parked on Wednesday now (Saturday) doesn’t start. It will only crank, crank, crank, sputter, sputter, crank, crank, crank. Giving it more throttle doesn’t affect it. The fuel pump is working. It ran smooth ounce it would warm up if it was cold it would run quite rough but would always clean up. It’sso not colder than it has been for the past week. I could use some guidance as to what to check.

Since it’s sputtering it would seem like it’s firing then. How old is the fuel? If its 3 years then I would say you need to drain it. Have you checked the fuel pressure to make sure the pump is still putting out the correct pressure?

we filled it up last week. It’s been 3 days. The pump was replaced 3 years ago with a Bosch pump. Has worked fine, tank was cleaned when reinstalled along with new lines and fuel filter.

It is a tbi car so the pressure should be around 14 from what I have read.

Sounds flooded.

Try holding the gas pedal firmly to the floor to activate "clear flood" mode.

Often, a faulty coolant temp sensor causes flooding when the Engine gets cold.

Check the plugs for wetness and plug in the block heater if so equipped.

Thanks

Step 2: wait for Jan to reply.

No block heater. Should I pull the fuel pump relay so it doesn’t spray nor fuel in?

When it was running the temp gauge worked fine. On the highway it would stay steady at the fourth line. If you let it idle for a while the temp would clime to the middle of the gauge then the fan would kick on and drop back to the forth or fifth line.

Coolant temp sensor is seperate from temp gauge sensor.

CTS tell computer how cold it is and sometimes lies on the cold side.

I've run into this a few times over the years.

Just a possibility, not proof positive.

Thanks

Is there any possibility that the thermostat is stuck in the open position?

It was replaced 2 1/2 years ago. Along with hoses, engine side coolant neck, and coolant. Have put about 10,000 miles on it since then.

When you turn the ignition key to the on position without starting the car, do you hear the pump for a few seconds?

What’s weird is it was fine on Wednesday we touched nothing. Then today I go out to move it so we can pull the table saw out of the garage and now it’s broken.

You found a broken vacuum line?
Old vacuum lines get very brittle and the cold weather will make them snap easily.

The one to the map sensor was already replaced as it broke before. I will check the EGR, evap canister, and brake booster lines tomorrow. (it’s dark and windy in PA currently) What other ones are needed to get it to run properly?

Yes I saw that, but some here have multiple cars.
