Testing for leaky injectors

I just got an idea... what if i jumper the fuel pump relay, and have the fuel pump running... with the engine off... then try to start it after 5 minutes. If it's flooded... it won't start, and that means my injectors are leaking. If its not flooded, then they're fine.

Does anyone agree with my logic? I'm running out of things to friggin test!!!! And the issue will only get ALOT worse if I put on an aftermarket fuel pump


Thanks

-Ross

Or...

You can driev your car around for a bit to get things warmed up and running (might only leak enough when it's warmed up). Then park your car, let it sit for 15 minutes and unbolt a portion of the fuel line as close to the injectors as possible. if there is pressure in the line, it should come out with a decent amount of force. If not, it'll be mostly drained and just dribble.

That's always worked for me on piston engined cars, I'm a rotary n00b :p

Sounds like it might work. I see no reason why not.

Looks like the injectors aren't leaking... well at least not at the pressure @ the jumper thing.

So... back to square one.
