finally got the fd ready for its first start up. did my research on how the fuel lines were connected. i finally go to start the car and i notice that there is fuel leaking from the DP. dont wanna go and start the car just yet now...

i dont know where to begin help is very much appreciated

 

You might verify if it's leaking from the downpipe or further inward (like the LIM gasket). If it's just the downpipe, then it sounds like you flooded the engine and it's pushing the excess fuel out of the exhaust ports.

 

im sure its the dp cause i have no mid pipe right now. when i was cranking i smelled fuel. re checked the fuel lines checked under the upper intake manifold and no odor of fuel from there. then i checked underneath the car and there it was. this also happened to me with a fc that had rtek. that **** was leaking from the header and turbo exhaust housing.... scary

 

you might have bad o rings on the injector rails ... that are not sealing that dump fuel in the engine under pressure ...

take off the fuel rails ... pressurize the system ( jump start the fuel pump ) and look at them upside-down ( injectors facing the sky )... the problem/solution will be obvious

 

hey the feed goes to primary first then secondary?

 

Remove the UIM for full access to the fuel system. With the engine off but key in the run position, jumper the fuel pump diagnostic connector to pressurize the fuel system. This should show you where it's leaking from.

 

just did the selftest and no leaks. are all injectors suppose to come on?

 

You should pull the fuel rails and do the test like this:

The fuel lines should pressurize with fuel, but no fuel should come out.

 

ok ill try that next. but i still didnt see any visible leak... and it still doesnt explain the fuel in the exhaust. on the second gen it turned out to be faulty injectors

 

If you have a leak around an o-ring or a stuck injector, it will flood the compression chamber with fuel. When you attempt to start the car, the rotors will start to push the fuel out of the exhaust ports then out exhaust. If you have excess fuel in the compression chamber, where do you think it's going to go?

 

^^^ JAJAJA turns out that was the problem. the top oring on the injector is ok. but the one at the bottom was missing, on both! a stupid mistake. oh well, a great learning experience none the less!!! thanks Mahjik!!!!!

 

finished putting everything up last night and started to crank the car with no egi and no fuel pump relay. its still pushing out some fuel. another thing that i noticed is that the car starts up. is it suppose to do that?

 

you sure you have the egi fuse pulled? it shouldn't be starting

 

yes but everything is ok now. just finished installing the stock cat and need to put the intake stuff on. the o2 bung was stripped so i took off the exhaust dp last night to re thread it. worked nice. since everything is off from the intake y i was gonna heatwrap the wire harness..

 

another problem im having is the fan is turning on while the key is off... any ideas?
