Is the service engine soon light on? Read codes tis way...then test fuel pressure.
https://www.2carpros.com/car_repair_video/test_fuel_injection_pressure.htm[img]https://www.2carpros.com/forum/autCross these two terminals as shown, then turn the key on. Count the flashes, a 22 will flash as 2 flashes then a short pause, then 2 flashes, if more than one code is stored, the pause will be longer. The codes will display three times and end with 12. Write them down and post here.
