Toyota Repair: Fuel in the oil, kevin braun, ground path

Question
I have a 1992 Toyota Previa 2 wheel drive van.
184,000 miles on it.
It started out missing at start up after sitting for several hours, but started fine if setting for a hour or less.
So I replaced the spark plugs.
Still missed at start up, so I replaced the plug wires.
Then when I went to start it, it sounded like it was hydrolicing or coming to a real tight spot.
I did a compression test the lowest cyl was 135,
But fluid came out of cyl #2. It smelled like gasoline.
I thought maybe I had a leaking fuel injector so I replaced the fuel injectors.
I did every thing the book said I removed the gas cap and released the pressure at the fuel rail.
When I put the fuel injectors in and went to start it, it seemed to hydrolic again, but did crank finaly and started.
I let it sit for a couple of days because I was frustrated with it.
When I jack up the van to look at things better I saw something dripping. Smelled it, it was gasoline.
I drained the oil, it was full of gasoline.
Any idea where it is coming from?

Thank you ,

Answer
Since there is only fuel getting into the #2 spark plug and all the injectors are good there may be a computer problem or the injector is constantly grounded which causes it to stay open.
There are two wires to each injector, one is a constant 12volts and the other one is switched off/on through a ground path by the computer, check which one is the 12V wire with a test light then check to see if the other wire is grounded to the body or engine, with the key off and the engine off there should be no continuity to ground, if there is, disconnect the connectors from the computer and see if the ground goes away, if so, the problem is in the ECU, if it's still grounded start checking the wire harness, the wire is shorted to ground someplace.
You can also check injector signal with a special small test light that plugs into the connector(available at most autoparts store)then when cranking the engine the test light should flash, if not there are the above mentioned possibilities, good luck with this.
