Fuel relay problem?
This seems a little odd, yesterday went out to my car in the AM to find it exhibiting symptoms like it was flooded.
Started to catch, then spiiiiiiiiiiiiiiiin!
Pulled out the plugs and cleaned em off, the trailing plugs were coated with fuel. Still no go. I noticed that I didn't hear the fuel pump prime/cut on (or maybe I'm losing my hearing). At any rate, I decided to check for voltage from the relay to the fuel pump. When I used my voltmeter on the relay the wire that goes to the fuel pump was reading ~ -12V. Odd...negative? Verified that the meter wasn't bullshitting me by going over to the battery getting a reading of ~12V.
Ideas? Shot relay?

Maybe the Apex seals went for a night on the town and didn't think you would be back untill the PM?

Sorry to hear about the compression. Sux

PS- I had a question about the fuel relay. Does the Microtech stuff use the stock relay or do you wire it up independantly of the stock relay?

Independant of the stock relay, just a basic automotive relay that's switched on by the ECU itself.
I can get chugs, but no go still, keeps reflooding. Going to try some more things today...got gas (vapors coming out of the exhaust begging for me to ignite them), got spark (checked leading), thinking I just have a really really flooded engine.

Get a battery charger on that cell man. Once my Sport was really flooded and I couldn't de-flood it. I charged the battery and it fired up on the first try.

If it had that much unburnt gas coming out the exhaust, it's possible that the apex and side seals have been thoroughly washed with gas and are not making compression. Do the usual de-flooding procedures (remove EFI fuse and/or unplug the fuel pump) and spin it with the throttle wide open to get the gas out.
Then, using a little squeeze oiling can, squeeze a little two cycle oil through the spark plug openings to get the compression back. Reconnect everything and drive away happy!
