Default help get this fc back up in running

fucking shit is pissing me off hope some of you guys can help me out heres a video, and heres what ''i'' think its doing is its only getting fuel to one rotor, but how can this randomly be ? ive replaced the following parts with known good ones to see if these were the problem
n/a s5 maff
n326 trailing coil
440cc injectors ''primary's''
new ngk plugs
new main relay
ive also reved it up and the revs take forever to get to 5 grand than once it reaches 5 grand it acts like 2 step and back fires and if u give it a lot of gas it also back fires
much help would be great YouTube - rx7 running like shit for sale 4.000 $
i will give someone ether rotary parts of choice, or cash if they fix it heads up ford electronic guys

have you check to make sure your secondaries are coming online, check to make sure you have power to all injectors and that your getting a signal to all four. what impedance inj are you running?

you can use a dmm set for dc and back probe the inj plug, and run the car and you should see it switch from 12v to ground. or you can buy/borrow or rig up a inj test light adapter.

Walboro's are known to fail every once in a while. I would definately check the pump and re wire the pump if it hasnt been done already simply to allieviate the possibility of it fucking up later if its not already. Also second the new fuel filter, its only a few bucks and its good to do.

Check the injectors with the multimeter like was suggested. If you are getting the proper reading and the cars still not running properly, i have a guy that cleans and repairs injectors (flow tests, o rings, the works) who charges 20 an injector. It might be a good idea to have them used injectors cleaned up a lil, and his shop is in Temple terrace so the turn around is usally a day or so max.

Other than that? well we'll have to go from there when we establish that the previous checks didnt resolve the issue.
