like the title states i've got done doing a swap to me EG and everything was fine. until i went to go get my tags. the ecu fuse blow out every time i turn the key to accessory? i've checked most of my wires and haven't found anything. I also have a walbro 255 fuel pump that was acting up before but i'm not sure if that could play a factor. I have friends that put 255's in and blew a fuel pump relay... ? any takers?!

 

no one? i'll keep searching..

 

its a short somewhere.

 

Unplug the vss and put in a new fuse and see if it pops.

 

ok will try and let you know how it goes.

Tried it today and it's still the same. I'm beginning to think it's the ecu itself

 

could be try a different one

 

Repalce the fuse, use a Digital Multimeter, set it to volts, put one led on ground, then prong one wire at a time at the ecu...should not read more than .5V with key on engine off. Test your fuse box with a test light, with the engine off with led on ground, there should not be any power, if there is you are half way there.

 

tried it still doesn't work, here's a lists of what i have tried...

Unplugged everything such as ecu, fuel pump, injectors, O2..
except the main relay and it blows.

Ecu is fine, plugged it in a friends car and it worked prefect.
Fuel pump has been changed back to stock and unplugged and it still blows.
unplugged O2
Unplugged Injectors

I unplug the main relay it doesn't blow. I changed it out with a brand new one and it still does the same thing. This is becoming such a big headache.

Everything is factory specs.

Any other ideas??? I could use it.
