Q: After engine sets for 6+ plus hours it hardy starts

asked by on October 02, 2016

The truck turns over like it should but after overnight setting it takes multiple attempts to start. Just changed all fuel injecters and the coils n plugs are less than a year old. Fuel pump is less than 2 years old. I had a hit and miss problem with missing coolant and plugs may have have a slight green tint. Truck runs and starts great after warmed up. P 0172 is code but tail pipe is off truck.

My car has 105317 miles.
My car has an automatic transmission.
