Whats up with my 85 GSL-SE??
well today i got an alternator and the trailing ignitor for my 85 GSL-SE, when i start it it will run for about 2 seconds and then die, if i repeatedly push the gas to the floor and let off really fast it will stay from 500rpm to 1200rpm, but if i floor it it backfires really really loud and dies, whats up?? bad injector or something?? help me please i want to drive this thing now lol

Not an -SE expert but it sounds like the fuel pump is only running when cranking.
So - crank engine - fuel pump kicks on - engine starts - turn key from start to run - fuel pump shuts off - engine dies after a couple seconds. Maybe controller doesn't see engine as running? (did you put in a GOOD trailing ignitor?) I've also seen a faulty ignition switch do this on another Mazda (non-RX-7 tho).

8krpm is not enough
check your plug wires, if you have them crossed it'll really fuxor things up. You also might want to check your fuel pump/filter/system, how long has the car been sitting since you last drove it?
hope you get 'er running!

Do as speckamp says regarding plug wires. Lead wires go the the bottom of the housings, trailing to the top. Distrib cap is marked L1, T1, etc.
Pop open the air-filter box, and while a pardner turns trys the starter shoot engine start spray into the intake hose. If the engine keeps running you've got fuel filter/fuel pump problems. Tackle the fuel filter first.
Cheez, a New Mexico SE...All I can see is a NO Rust Seven. If you find that the little hoss ain't your baby send me a PM and I'll add the little "nasty" to my corral. That's if I can beat Max7 to it.
Best to yuh..
