Fuel Pump Rewire Problems
 

Okay so me and a friend just rewired his 10th Anni's fuel pump and now theres no power going to the ORIGINAL power in wire, black with white stripe, when we turn the ignition on. Also the car won't start. Any ideas?

you won't have power there unless you are

a. cranking
b. running
c. fuel pump jumper in the front is jumpered and key to on.

having the key to on by itself doesn't make the pump run (power on the stock wire)

since you had the pump out. you might need to prime the system. jumper the fuel pump jumper in the front (pass shock tower) and turn key to on and leave it for 30 secs as fuel flows. and check that you have power and you can hear it.

The Black/White wire should have 12v when the key is to ON. That12v gets there when the Main Relay is pulled in. I suspect you blew the 30A fuse up in the engine compartment.https://www.rx7club.com/forum/attach...postid=1398836

Blowing that fuse kills the power to the ECU on pin 3I, I think. So the car won't start. Gotta have 12v at 3I of the small plug on the ECU.

All figured, had some wires setup improperly. Just had to set em right and away she goes :)
Thanks for the help though guys.
