RX300 was running fine, although the gas mileage sucked so I cleaned MAF, cleaned throttle body, changed PCV valve, chenged air filter and changed spark plugs and now the vehicle cranks but doesn't fire. I checked 2 of the plugs and no spark.

I re-checked all the connections and hoses that I disconnected and they are all snapped/plugged in. I checked the 2 ground wires that I took off and they are tight and clean. I had the battery connected during all this work so I disconnected it and let it set a while then re-connected still no spark.

Also, I am going to change my O2 sensor (it's dangling because the studs broke off) but I need to get it started so I can drive it to my shop where my torches are).

What am I missing other than my daughter's soccer game?

Even though the ground wires were 'clean' they weren't making a good ground. I removed them, sandpapered down the contact surface, put everything back together and fired right up.

What got me thinking it was a ground was when I was cranking it and it wouldn't start my RPM gauge was going wacko and a relay in the fuse panel under the hood was buzzing. In my many years of troubleshooting electrical controls in the HVAC industry, when **** starts acting weird check your grounds and electrical connections.

Glad to hear you got it all figured out!

There is nothing like the feeling of doing it yourself and it is awesome having a forum like this to turn to for insight into the many tasks we need to perform on our RX's.

I am hoping in the future I can help out all of you as much as you've already helped me.

I will be painting and clearcoating the wheels soon because they are starting to blister. Does anyone care to see a step by step on the process with pictures? My brother has owned a few bodyshops and is a master bodyman and painter, he said he would give me some tips....

Yep stock wheels.
