Starts easily, must continue to pump the accelerator pedal to keep car running. Fuel pressure is 50 lbs at the rail. Replaced fuel filter, added fresh fuel, replaced plugs. Timing belt changed 30,000 miles ago. Codes P0300, P1390, P1300. Can drive it as long as keep pumping accelerator pedal. Replaced battery also. Car was sitting for one year. What is wrong here. VIN: YS3ED45E2X3000251

Ok let go, r those the only codes u have?, Note all your codes r misfire related codes, u may need to take injector out & clean them additive dont work at this point, did u check for any leaking & pulled off vacuum hoses in the intake & fuel pressure regulator areas, if not check for vacuum leak, note u may need to replace injector if u try cleaning & the p0300 code returns , also check spark plug type not all plugs work well in these saabs, recommend factory installed type plugs platinum ngk pfr6h-10, good luck post back after u check system.
