Burning coolant has in many cases on this forum taken out spark plugs and O2 sensors. You will want fresh plugs to start with. After the engine is assembled, take out the old plugs and throw them out. Leave the new plugs out and crank the car for several seconds (It would be wise to pull the ICM and injector harnesses to keep fuel and spark from happening). This will dry out your cylinders, and keep coolant vapors from ruining your new plugs. Install your plugs and try to start.
When it starts, you will probably smoke a little (oh, keep in mind I am going on the assumption that you had a hard fail) as the cat is buring off coolant. If you CEL comes on, assuming all the sensors are hooked up right, it will either be a misfire code or O2 code.
And even if you did so already, change the oil. Your motor will thank ya
I just found it wouldn't start. I did get some slight firing, like the old cars on a cold winter day when they flooded out.
I looked at a plug. Wet.
I started to put in the old plugs I had taken out when I put in the current iridium Delco plugs. But I'll take all the current wet plugs out and spin her a few times to do like you said...
I'll put in the old plugs. Run a while and then put in new plugs--hoping it will start with the old previous set of plugs..
When it failed it had just started running rough after about a 1/2 mile trip and turning a corner, probably taking in more coolant off the bottom of the plenum area. The CEL came on and it limped home about 1/2 miles. But it ran better on way home after CEL came on...
I found that 5 of the plugs were wet and oily black, probably the oiliness is coolant. #6 plug was black sooty.
