Motor Swap Update, Day 5
The good news...
The motor/tranney/SC is 100% in and ready to fire up.
The bad news...
It didnt fire but once or twice. Apparently the crank shaft position sensor for a 96 is different than that of a 98, go figure. I had my 98 in the 96 motor when we trid to fire it up. It didnt hit, we pulled a plug and grounded it and got one spark from 15 seconds of cranking, WTF? So we brainstormed and decided that is was the crank shaft position sensor. They are visually different. When I swapped the sensors we got good spark but it still would not start because the motor was flooded AND to top that off I had put a cap full of oil in each cylinder a few weeks back when I did some out of the car compression tests, so the plugs were quite fouled. I pulled the plugs and cleaned them and am leaving the car to sit over night to let all the fuel evaporate out of the cylinders and exhaust. I'm hopping it will hit tomorrow night, I'm gonna get some starting fluid just incase the oil in the cylinders is still a problem. Any other sugestions are appreciated.
Sorry no new pictures, I'm just freakin dead tired!

Ahh, the suspense must be driving you crazy! Or maybe your so damn tired you don't even want to think about it
. If it was me I whould be out there cranking it every 2 minutes, lol. As always good luck dude!

Emax, your right about being so darn tired that I blew it off for the night. But I would be able to sleep if I wasent so sore. It blows when you wake up every hour or so because your so sore you have to change positions, it is what it is though!
Jeff, After we dropped the tranney from the bottom, the motor hoist out the top was a piece of cake!
I'll play with it tonight when I get home from work. It should be un-flooded and I'll hit it with some starting fluid.
Do you think its ok to sprak the starting fluid through the supercharger and into the pipeing with the MAF sensor and all, or should I spray it through a vacuum hose?

No dont spray that starting fluid thru your supercharger. Whew dont wanna burn up a good maf sensor either. I presume that you have installed an aftermarket fuel pump. I say turn the key to the on position let it sit there for oh say 30sec let that fuel pump get those lines full of good fuel. Then dont dare touch that gas pedal. Try it then after installing an engine in one of my toyotas I had to leave the key on for like 30 sec before it feed good fuel to the engine. Now you say it was flooded but are you sure. Check all those fuel connections and the what nots. Well thats just an idea

I guess I'll find a way to spray starting fluid through a vacuum line or somthing if it still dosent crank by its self.
Thanks
It still wont start...
I tried it again tonight and it would not hit. It would bairly stumble. I pulled the plugs and 3 are sooty and 3 are clean. I feel that one of the 3 timing sensors, REF, POS or CAM is some how not working properly. After looking at the FSM I have some targets to attack.
Check all the grounds.
Check all 3 sensors for propper readings.
Check all 3 sensors harness connectors.
I know that.
Fuel pressure is good.
Compression is good.
So it most probably is an electrical issue effecting either ignition timing or fuel injector timing.
Are their any known differences between 96 and 98 engine controll sensors?
Any helpfull input will be appreciated!
Now to get some rest.

Re: It still wont start...
3 plugs: All from the same bank I assume ie.. front/rear bank?
Check to see that the fuel rail is not bent(ie.. crimped) The VE maxima has a solid fuel rail but to get to the front bank to the rear, it uses a rubber hose to cross over. Maybe that one is clogged/crimped/etc..???
Oh maybe the front / rear 3 plugs aren't firing for some reason? The direction for checking the grounds etc. is sound. Let me know what happens.
Since the VQ should have these sensors, they take readings off the crank but uses that info for ALL 6 cylinders correct? So I don't see how just 3 out of the 6 could be affected by ie.. CAS sensor.
If the 3 bad plugs come from the front AND rear banks, then something is definately fishy. I would have to think about that one.

Re: Bring that VQ to Life!
I'm waiting here 10,000 km away for the news, If all goes well i may follow your lead. Though I'm thinking of using VQ30Det pistons and more boost, anyway best of luck man, waiting fo the good news.
