Ok here's the scoop been lurking here for awhile and read tons of posts but nothing to fix my issues. I purchased a 87 924 with the trans out supposed to run. put tranny in then it wouldn't start been through Clarks garage checked all I could think of so here I am. new computer, tack bounce plus both sensors ohmed out ok no scope also if either is disconnected the it quits firing ,35pis on fuel rail, new plugs,good relay, tried the jumper wire to, good ignition switch also tried the jumper wire, good coil, noid light says the injectors are working, vacuum tested the intake no leaks, took timing apart lines up right, good cap, good rotor, new starter I'm am not a automotive virgin but my first and maybe my last Porsche cranks fine and fires and pops but when the key is let go it all stops almost like the timing is to advanced backfires and stops the starter sometimes sorry if this seams drawn out I just want to get the most info out to stop the routine questions please help this thing may soon become target practice  school is starting soon so I'm running out of time thanks Bill
