Buick Skylark Repair Question
All major ignition components have been replaced
In warmer days it started fine now in single digit temps , it will fire for a second, stall. to start after that involves several attempts with the peddle depressed partialy. run stall over and over. finaly start and hold peddle a minute, after a noticable change in engine, it runs fine.untill it sits over night.Also fuel filter changed, injecters cleaned, with the machine, not gas additive.Also if related on ocasion severe hesitation, studder off the line. Thanks very much.
i would start off by checking the fuel pressure , and watch the gauge to see if the pressure drops quickly ,if you get a pressure drop this would most likely be a failed fuel pressure regulator , but check the pressure and lets go from there
