Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Can you tell me which engine you have? The 3.4 or the 3.8?
The fuel pressure regulators on these engines have had a ton of problems. What is happening is that the regulator fills the vacuum line that connects to it with fuel and on a restart, it has all of that raw fuel being drawn into the engine, thus, flooding the motor...
Pull the vacuum line off of the regulator and see if a fuel leak or fuel is present in the line. If it is, replace the regulator...If it is not, run the engine for awhile, pull the hose of a wait a few minutes to see if the leak occurs.
I had the same problem on 1 3.8 engine that took me 2 days worth of checking to get it to act up...
The fuel pressure regulator is located at the end of the fuel rail next to the throttle body..
