Replaced injectors, need to bleed?

Just had my injectors serviced.

Not sure if its still flooded from before I had them serviced or if there is air in the fuel system now that I've replaced them.

Is there a bleeder screw on the fuel rail?

Nope, the fuel circulates back to the tank so it will take out the air that way.

Are you having a problem, ie not starting? After 24 hours of not being on, the fuel pressure in the lines drops very low. If you're flooded, then de-flood. If you've replaced the injectors and want to prime the system, jumper the yellow connector near the passenger strut tower.

I'm running a Haltech Sprint RE. Which wires would I need to jumper with that setup to prime?

Or is there another way?

I also can't get my ecu to connect to my laptop. I keep getting the error that no ECU can be found.... I had it wired in buy someone who does wiring of ECUs. And he put the map I gave him on there with his laptop.

Tried with the key in the "on: position and still can't detect the ECU..

Always check the fuses... Did he wire in a kill switch somewhere?
Also when you switch the key to on, the computer will prime the fuel pump. However if it's not detected, you have bigger issues...

There is no fuel pump noise anymore when I turn the key to the on position. I pulled my injectors and had them serviced and now nothing wants to work. I hooked up everything back the way it should be. It turns over though.

The starter circuit is separate from the ECU circuit.

You need to check for power to your ECU...like fuses as mentioned above.
