Injectors leaking from electrical connection...HELP!!!!
I bought an 89 IROC in pieces and had to install new head gaskets. After putting the engine back together and starting it for the first time, I noticed that both the #2 and #4 injectors were leaking at what appears to be through the electrical connections. Has anyone seen this before? I'm sure that is where the leaks are coming from. I disconnect the harness from these injectors, soaked up the fuel sitting in them and turn the ignition on to activate pump. The electrical sockets slowly fill with fuel!? Just trying to find out if this is common (possible) before I replace them just to find out it was something else disguising itself. Thanks in advance!

I dont think its possible, unless you got some holes in your injectors, I think what is actually happens is that you have a leak at the top and the fuel runs down into and fills up the connector port.

:Sure you haven't got the O ring into the fuel rail above the injector leaking?
Did you fit new O rings when putting the old injectors back in ?

Fuel can come up thru the electrical connector if there is a internal failure. Your injs are unsafe (fire hazzard), replace them.
