could this be my problem?
ok so i went bak to work on the 7 today and found that this ground wasnt hooked up to anything. does anybody know where it goes? or can it just go anywhere on the engine? and also i noticed my injector clip is broken can i just cut clips from any other car and rewire them into the harness or do i need specific rx-7 clips?

ground goes to the upper manifold I beleive, that would also be why it isn't hooked up in that pic????
Edit: Since we don't know what your problem is,well, that MIGHT be it - it might also be the fact that your missing an upper manifold and throttle body - hehehe

ok well the problem was that my injectors arent putting gas into the engine. someone a while bak said it could be my grounds and i noticed this ground wasnt hooked up to anything. this is the ground that is attached to the wiring harness, there is another ground wire that is by itself and it went from the tranny to the firewall. but this one im not sure where it goes to. and to specify the picture, the bottom part of the picture is the tranny

ok well i hooked up the ground and!!............. nothing i got nothing. help please!! what can it be? i got spark because i sprayed starting fluid and it fires up for a second or two before it eats up the startig fluid. one of my 2ndarie injector plugs are broken so it wasnt hooked up. but does that effect the primaries? i wont be using 2ndaries for a while(new rebuild 2000miles) so i figured i can fix the 2ndarie clips later when i actually need them.

You have left the electrical plug off the AFM. Reconnect it and try again.
Or your fuel pump is not working. Jumper the fuel pump check connector and turn the key to ON. The pump should run continuously now. Listen at the filler cap (cap off) for the sound.
Or you connected your fuel lines at the engine assbackwards. Swap them back to where they belong.
Make sure the EGI INJECTOR fuse is good.

no one ever remembers my advice, it makes me sad.
like Hailers said though check your fuel lines the fuel line off the filter goes to the forward lower steel line and the one to the firewall goes to the rear lower steel line. make sure your MAF is plugged in and try cranking the engine for 1 second and see if you can hear the fuel pump whirring by listening to the fuel tank.
somewhere along the line you aren't getting fuel and my bet it is the pump not running not your injectors since you have spark.
also try jumpering the fuel pump connector at the RF strut tower.

well my fuel pump does work, it is wired to a switch and it is a walbro so it whirrs loudly. my AFM is plugged in. what makes u think its not? the only thing is the fuel lines, u mite be right about that but my fuel lines arent like the original ones. the guy who had it before me ran the entire fuel system with rubber fuel hose. and the lines run thru a FPR with a pressure gauge attached. so its not really so simple to know which line goes where

Sure it is. Line from the filter is always high pressure from the pump, the other is low pressure return/drain. The injectors all need to see high pressure, and the fuel pressure regulator is the last thing in the system, and controls how much gets returned to the tank, so the return hose connects to it.

my pressure guage reads around 40psi when i turn the fuel pump on so yes, i do have pressure.

so why is it that nobody thinks it could just possibly be bad injectors? and yes fuel reaches the injectors because when i first put the engine in and turned on the fuel pump. the return hose that goes to the fpr popped off and started spraying pressurized fuel evrywhere.
