Fuel pump relay bad??

[Swifty1638]

I don';t even know if the coolant temp sensor is still hooked up to be honest. It's running off the AEM EMS, s stated earlier. All I hear is teh relay clicking off, and then the car dying. I don't know what else could cause this. It's also only when it's cold, which now, is daily. this is annoying

See anything in your AEM logs that would help?

I can't hook up the aem. My laptop is taking a shit on me quite often. I honestly don't think it's anything like that. Something is shutting the fuel pump off everytime the car finally starts, after cranking over soo long. But, once you do it like 13 times each morning, then the car will finally fire up. It's weird.

I'm guessing its an ECU issue pointing directly towards the AEM.

[Swifty1638]

how? what could it be?

I don't know, but it has to be something controlling the signal to the relay/pump. Could you try swapping in a stock ECU just to see how well it starts up?

[Swifty1638]

I dont have one, and i know that with the cams and everything else the car has i doubt i'd be able to single the ecu out as an issue

There is a box that can get unchecked that would cause that issue in the AEM. That is supposed to be fixed in the later versions though. I can't remember what box that is, I know Shane would know and probably Swanny. the AEM forums should pull it up also.

Honestly I would check the Alt. fuse. Damn cars will act like they are possessed if that goes!

[Swifty1638]

ok. Thanks jet.

If anyone knows what box this is he speaks of, please come forward!

Tools -> startup procedure -> 'when cold don't hard start'

...be sure it's unchecked ;)
