alright, I just got done building my 84mm lsvtec. I installed the turbo kit, and drove it to my house with my wideband plugged up, watching the a/f's. I had the car idleing at 14.7 rock solid. On the way home I kept it at 13.3-13.5 under normal acceleration, and 14.6-14.8 at cruise. Alright now for the strange stuff.

I got home and went to crank it the next day, and it wouldn't crank. I checked the timing, spark and fuel. it's got everything. I pulled the plugs to do a compression test. It came back 210-215 across the board. But #1,2, & 4 plugs were fouled and the piston tops were black, and #3 was clean and the piston was clean. #3 smelled like gas though. I pulled the dip stick and the oil smells a little like gas. The only thing I can think of is that my wideband needs calibrating. But I don't know. Any suggestions

 

anyone?

 

how did u do those tests if the car didnt crank?

 

you can smell fuel in all the cylinders, the compression test was a cold test, and for the spark just pull the plug and wire, and hold them next to a valve cover bolt. It'll arch if you have a spark.

that's not a accurate way of measuring voltage coming out of the ignition system. It doesn't tell you if it's a weak spark or strong spark. Get the right ignition spark tester instead of doing it the shade tree way.

 

alright, how to I test to see if it's a strong enough spark?
