So today Tom and I finished putting together his car after a long time of not running. So we go to start it up and the fuel pump isn't kicking on, we check the fuel pump fuse, its fine. Then tried swapping fuel pump relays from my car and it didn't do anything. So we decided to see which way the relay goes by putting it in my car and cranking it. My car didnt start, same issue with the fuel pump not kicking on. We tried flipping the fuse around and it still didnt start....The car was running about 12 hours prior just fine...WTH?

 

yes he broke your car too..shame

 

this BLOWS!!!! two dead cobalts

 

and a partridge and a pear tree!!!!!!!!!!!!!!!

HELP THEM !!! so i can go back to work

 

lawl/..help us so my car runs again!!!!

 

We're thinking it's because we pulled the relays while they had power....but not too sure....Any ideas???? Anybody???

 

Pretty sure the ECU controls the Fuel pump..

It could be a bad ground as well in the relay or even the pump..

 

But why would it do it on both cars? Same year and engine, his is tuned mine isn't.

 

unplug the battery and put the relays back, if i am correct shouldnt it reset the computer?

 

watch how you put that relay back in it's really easy to have it in the wrong slots.

yes, i did that dumb **** when i was changing my fuel filter if you need me to i'll get a pic up if you need it.

 

that will reset the computer, but not nessicarily solve our problem, his has been disconnected all night so hopefully its reset and fixed
Just tell me where pin 30 is located, because the cover doesnt dictate where the pins are. Its either upper right or lower left on the block.

A word of caution: I would remove your positive battery line before attempting to pull the relay out....that might be why mine and toms doesnt work, because we didnt remove it.

Another update, I called my dad (guru of all things car and otherwise I swear) He says it sounds like the ECU isn't "happy" for some reason.


Update again.....so we're idiots....the relays were in the wrong spot....we put em back, my car runs great again and his is running odd, but that is probably because he changed cams, TB, injectors, intake manifold and didn't get it fine tuned before starting it up. So we are resetting the ecu now and awaiting a call from Vince at Trifecta in hopes of getting it fixed today.

 

She Lives!!!!!!!

 

does it sound sweet with the cams

 

It sounds nasty, check his build thread for updates.

 

lol, since it needds fine tuning and stuff it kinda is ass right now...but with a little throttle it sounds AMAZING

 

ugh its a decision im trying to make with goin turbo or cams not to sure man

cams seem easy to install am i correct

 

car has been dead a mo because of that **** lol

 

haha **** that is true u def need to figure it out haha
