SOURCE: Starts fine when cold, after running dies on idle then wont start

Sounds like the fuel filter is dirty and needing to be changed. It's cheap and easy to swap out.

Most likely air flow metre. Had same problem analysed and replaced and runs perfectly. Not cheap!

After I start the engine it runs fine until it warms up to operating temperature and then runs rough and produces black smoke until t dies. It will not re-start normally until it has cooled.


Bad coolant temp sensor making ECU think engine is still cold, thus running rich, as if choke is on. There are two temp sensors, one for dash gauge (one wire) and one for the ECU (two wires). You can remove it and test with voltmeter by placing unit in hot or cold water to compare readings.

Motor starts then dies several times when cold


Sounds like the cold start solenoid. It is designed to keep the engine running at a set RPM until it reaches a specific engine temp.

2000 silverado 4.3 V6. Replaced feul pump and niw it starts but it takes 3-4 cranks in the morn to start it and then it runs very rough untill it has ran for 1/2 to 1 hr. Also have replace fuel filter...


The rough running should have caused the check engine light to come on. It would be a good idea to goa ahead and scan the engine for trouble codes. The rough running could be a number of things. The codes would help us pinpoint the correct part ot replace, rather than start replacing parts until we get lucky and hit the right one. That could be very expensive.

Truck runs rough at start-up in the mornings


If this happens only when the engine is cold or cool, I would suspect a coolant temperature senor that has lost its calibration.
One way to check would be to have the engine controller scanned when the engine is cool then cold.
The coolant temperature should be the same as the intake air temperature. If the readings are not close to one another, change the coolant sensor.
The coolant temp sensor controls the fuel mixture when the engine is cold, normal or hot.
Good luck, let me know.
