Just went out & started my son'* 99 with TPS unplugged. Then unplugged MAF & started with both sensors disconnected.

Thank you for info.
It will save me some time to look elsewhere than into TPS and MAF
But honestly no idea where else to look.
If sparks and fuel will be present,thenI'm lost so far.

Don't rule out those sensors until the scantool says they're good.

I'd go ahead and check for spark & fuel injector pulse. That'll pretty much rule out some how blowing a fuse.

I remember an old post where someone had coolant leaking into the intake after doing some engine work. IIRC he didn't all the old gasket off before putting the throttle body back on. Make sure the coolant sensor didn't somehow get unplugged. The only other things I can think of is a large vacuum leak or a problem with the IAC.

PS - Others have reported their engines not starting with the MAF disconnected. I have no idea why some would start & others wouldn't.

The coolant sensor UNDER the TB in the end of the LIM can prevent a start in certain temperature conditions. The one BEHIND the TB controls the gauge and has no effect on performance or PCM.

I 'm suspecting I didn't tight enough one of the bolts on TB.
The one tha goes with bracket for cables.
I was screwing it in and it was going not easy as two others.
I was afraid not to ruin it and maybe gasket has some vacuum leak and that srewing start up?
Anyway I'm planning to take TB out again tomorrow after checking spark,visual inspection of spark plugs and scanning sensors.
I have to recheck is surfase of TB was clean enough for new gasket .
I've read somevhere here it was an issue when old gasket wasn't removed properly and it caused vacuum leak and coolant into cylinder.
But in my case wacuum pump isn't powered.No belt on it.
And when I was removing TB there was not even a drop of coolant,so I don't know if that a case,but I don't think something just suddenly broke right after TB cleaning.
Low probability,but possible too.

You just explained your starting problem and your coolant leak.

Make sure you don't cross-thread the supercharger with that stud. They should be torqued according to the data in Techinfo/Specifications (link at the top of the page).

I was going to say water pump instead of vacuum pump.
Don't know whatI was thinking when typing . LOL
I think I don't have coolant leak because there is no water pump working and no circulation.of coolant. Or maybe it gets into cylinders somehow.

When you turn the key, the water pump turns.

Please fix your TB and come back with an update.

Yes,there was coolant in TB and I guess it was trying to fire up antifreese. I just reinstalled everything.Cleaned perfectly before installing gasket.
Battery was too week.
I cranked for few second.
It was about to catch but I guess it needs a little longer to blow all crap from cylinders.
Battery is charging and I'm out to remove accessory bracket.
Will post later when it fires up. (I hope)
