I have spark but no fuel pump

[siexyy55]

I tried to fire my m50tu swap today and it wouldn't fire up. So i tried some quickstart and it fired right up, so I have spark. I can't hear the fuel pump turning on, so i'm pretty sure I just need to figure out why the fuel pump isn't turning on. Im using a treehouse adaptor. and its an m50tu into an 88 325is. Also, I did s50 cams and a turner chip if that might be of any effect. Anybody have an idea?

thanks in advance

have you checked to see if the treehouse adapter is incorrectly pined for the fuel pump? should be pin # 13 to pin 13 between the adapter. also have you checked the main power relay for the fuel pump iirc it should be the blue one.

The pins look good on the adapter. And the blue relay is working, Are you sure the blue relay is for the fuel injector?

And when i turn the ignition on i hear a sound in the engine bay, I thinks it's the injector pulse but no fuel pump

jump power to your pump and see what happens.....

I jumped power to the fuel pump and it runs. So all i need is to figure out why there is no power to the fuel pump

ends up I testing the relay the wrong way and it was the problem after all.

Cool, so your running now?
