I sure hope nothing breaks because of a fresh motor and hotcam. Im running out of money for this thing, still have lots of plans for the house.

You're lucky your wife isn't on here, Nate, I can't get away with saying those things.

She wouldn't care anyways. Starting it with one o2 sensor, ok or not?

[meissen]

One o2 entirely, or one set of o2s (fronts)? If just fronts, I'm not 100% familiar with OBD2 cars but I would think it'd be OK it'd just throw a code.

[nascarnate326]

Just one front no rears. The fronts make the PCM change things, the rears just turn the ses light on.

I drove for two years one one o2

It all depends on how much you trust the open loop fuel tables from a mail order tune. I would want accurate fueling for a first start, especially after a rebuild.

Its my understanding that the car doesn't read off the o2's until it comes up to temperature and goes into closed loop. So starting the car to check for leaks and ect wouldn't even allow it to get into closed loop. Am I off base?

Yes, that is correct. Since it won't be going closed loop, you have to trust the open loop fuel tables. Typically min ect for closed loop is around 90-130F so it doesn't take that long. If it was able to go closed loop, fueling can be adjusted.

Im going to take the risk and fire it up tonight. Its hot cam not a 847

Still waiting on my new plate to show up too.

[nascarnate326]

When it rains it pours. Battery was dead, had it on the battery charger/booster for couple hours last night. Seems like it doesnt have power like it normally does.
My gauges dim, dont remember them dimming. Going to try a different battery tonight and see if that helps.

The motor is turning over, but kinda feels like something else is wrong. Going to pull a plug and see if we have compression like we should.
I have two short videos for you guys.
