removed hks safr, now car wont start. WTF!!!!
as title states, the car wont start
actually, i think it has nothing to do w/ the safr
im pretty sure its the fuel pump but thought id ask for some opinions and advice anyway
wouldnt hurt rite?
so my car TRIES to turn on, the rotors spin, im getting spark from the spark plugs, new battery and the car does not turn on
i tried push starting it to no avail
im i right? is it the fuel pump? can it be something else?
thanks in advance

YES!
i made sure of that. that was priority number one. thats what makes me lean towards the fuel pump. that and i had trouble w/ the fuel pump before but never changed it.

Did you reconnect the AFM wire that you had to cut to install the HKS AFR (or at least, that's what you do on an SAFC)? You also need to make sure that the circuit opening relay is getting switched correctly by the AFM.
Also, jumper the fuel pump check connector by the passenger side shock tower and see if you can hear the pump running with the key in the "on" position.

You'd jumper the yellow, two socket, fuel pump check connector and turn the key to ON. Listen for the hummm of the pump and listen for the flow of fuel thru the fuel rails.
The electrical connector above is near the right front strut tower and is not tied down to anything.

well, everything behind the strips is completely stripped. no rug, sound dampening, plastic covers, anything.
when i turn the key to the "ON" position, i dont hear the fuel pump "PRIME".
so, thats another reason why i think thats the problem
but thanks for everything guys. its all much appreciated

Damn it. There is NO SUCH THING AS PRIME!
Either do what ARGHX suggests or stop writing. You write but don't say whether you tried what he suggested or not. You go off on some GOOFY tangent that isn't relevant. Arrrrrrrrgh!

I replaced the pulsation damper (it was leaking BADLY) so the car starts now. It wont go past 2500rpm. I think it is the AFM wire. The only bad thing is, i dont know anything about the ECU/harness. What does it look like? What color is the wire? Where is it? Is it obvious where it should go? The HKS SAFR was already in the car when i bought it. When I removed it, I just removed the wires that were spliced into the ecu. flame on.

Download the fuel and emissions section of the factory service manual. Look at the "control unit" section or whatever. There is a pinout of the ECU. note that the diagram at the end is from the back of the connector, the side with the wires coming out.
There are also wiring diagrams that will show the wire color. It is in a different section of the FSM labelled "wiring diagrams"

I reconnected the AFM. It was pretty obvious, the only wire that wasnt connected!!!
(im an idiot). Anyway, NOW THE CAR WONT IDLE. It turns of fine, runs fine, everything. It just wont stay on. Even after the car has warmed up. What could be causing this?

Once again, I dont stop and think. When I installed the pulstaion damper, I tightened the little screw inside all the way. So now theres no fuel being delivered to the motor during idle. Would I be correct? Im just waiting for the motor to cool down before I go in there and fix it.

p.s. Ill also be sure to check the tps and idle adjustments

Well, I loosened the screw as much as I could. My car struggles staying on but still dies. The idle is set correctly, I just need to check the TPS.

It is a HKS SAFR (which is for sale btw). It was already installed when i bought the car. Although, the fuel injectors were stock and one needed replacing. I really didnt see a reason for it since NA rx-7's have more than capable fuel systems stock.
