2004 700 efi fuel rail issue

Got the new tank in, and changed the plugs while it was off. also took the injectors in and had them cleaned and tested. Hooked it all up tonight, but still didn’t start.

Noticed fuel on the left side. Discovered it was coming from the injector, left side had a slightly torn o-ring when I took it out.

Not sure if this is why it wouldn’t start. Perhaps fuel pressure wasn’t high enough in the rail since it had a small leak?

Getting new O-rings tomorrow, and I’ll see if I can find a fuel tester. I’d also like to get a NOID tester.

With the tank back off, I shot a little starter fluid on the cloth around the air filter, and it fired and ran nicely for a short while. (I know this is not recommended.)

So it’s definitely a fuel system problem. Hoping it’s just the leaky O-ring, don’t want to put any more money in this machine!

Thoughts on the leaky rail preventing it from firing?
