Have Truck Repair Questions? Ask an Expert
Thanks for asking your question and requesting me. I will try and help you out.
When the engine starts, then shuts down. Correct? Does it run a little rough and maybe smoke for a minute then clears up? Or does it restart and not run rough at all?
Thanks for the information.
It definetely sounds like the fuel is leaking down overnight. I've seen this many times on the C7 engine. It a common problem.
There are two things that will cause this.
The first and most common is a faulty fuel pressure regulator on the back of the head. I would replace it first. When the engine is off its suppose to hold fuel in the head.
Second is a faulty fuel pump. If replacing the regulator does not help. I would replace the pump. 9 out of 10 times the problem is the regulator.
Please reply back if you need more help or have more questions. I am happy to assist.
