2002 S80 NA will not run longer than 10 seconds

Post by Drdave007 » Wed Jul 17, 2019 10:49 am

got this 2002 s80 very cheap because no one could make it run, I think i am a competent technician, has fuel pressure 55-60psi,
injector pulse good,swapped injectors,ignition firing on all six coils, timing belt in time and hasn't been messed with. will run for ten seconds then sounds like it leans out, spraying carb cleaner makes it worse but plugs not fouling. if you grind on starter it will almost crank sometimes but sounds like its a tooth out in timing or real slow. compression 100 pounds . any ideas???? all help am very thankful for.
