Alright so it's been a while since i last posted, but I finally have the car running (Mostly)

First off I can't get the fuel pump to turn on and pressurize with the ignition to on. When I ground the wire under the dash (The brown one) on the Fuel pump relay it will turn the fuel pump on. After the car is running I can disconnect that ground and the fuel pump will stay running.

Next thing is the cold start. If the car is cold (After I pressurize the lines and such) It will start, rev to 1500ish RPM's hold for 2-5 seconds then die. I can do this a few times then it will finally hold and keep a constant idle. As well, if I tap on the gas at all when it's trying to cold start it will kill it as well. I did just swap in another Air flow sensor (used), but never had it tested.

As well it's a 1987 RX-7 Turbo

 

the fuel pump does not turn on until the engine starts pulling air through the afm. On the cold start do you have the thermowax still on the car?

 

thermowax?
