SO STUMPED! starting problem, help pls..

[DawgB0]

Aite I brought me 92' turbo wit stick for only $800 already knew it not going to run..
Im tryin to start it front of the yard and say sucker to them that I got it to running condition. But all I keep gettin backfires, smokes sometime white but black mostly time in back of exhaust, and vacuum hoses behind the engine next to the EGR keepin pop apart when crankin engine.

The pix; I was removing the spark plugs and cleaning up the oil all over the place the galley, didn't work out..
I had the wire-sets in correct places, found loose wire to starter from battery n tighten it, had adjusted my timing belt back to correct tooth at TDC and the belt is in new condition. I tired starting fluid, but I keep gets nothing just cranking so I knows the fuel pump works and starter too because I felt the starter bolt was HOT then I tighten it, then starter become hot means it's getting right connection, checked all fuses; all is good.. I had a new battery full charged I used it for my van with no PROBLEM, even I jumped the supra and ALL IS SAME RESULT just rollover until i let go the clutch, yea the CPS is GREAT! wow, I'm stumped.
if wondering about voltage drops, nope it keep coming back to 12v means ALT is great too!!

Hi! If that is a current condition picture , then the coil pack needs to be bolted in place across the cam covers , the coil plate NEEDS TO BE EARTHED !!!! ,if the small wire is broken -make a new one , the coils are open curcuit at the moment so no sparks.The plate is mounted on rubber grommets so there is no direct earth route and that is why the earth wire is SO important .Also, ensure the AFM wiring is connected , this is important too, -left mine off once , fired and stalled , fitted--fired and ran nicely.

Yes, the air filter keeps dirt out... It's not a sensor or anything. Put a sock or a piece of woman's stockings over it for now. Doing both will work even better. Make sure they're very securely tied/rubber banded on. Don't cut them too small so that if they happen to come loose they won't make it past the throttle body. I strongly advise against driving it with anything other than a real air filter though.

No, im exactly a student auto mechanic rite now, jus i have strong experience with mechanicals. Just learning electical system right now thats why im not smart with this part just yet. I has done muti swaps with no plm, rebuilt 2 engine with great result, replace all fliters, wires, spark plugs; basic tune ups.. everybody, sorry grammer aint my strong skill. Jus be patient wit me unless im nt makin nonsense lik others

Yeedaimean, i got it runnin now only at idle, lol.. idk wat i did bt what i did was bring back a full charged battery and replaced the vacuum i got 2 of dem wrong and got it correctly now it dont even smoke anymore just backfire few times but it idles now after o pull spark plug nbr 1 n check if have sparks it does, but plugs is terrible and planning to get me new one in any mins so what else i should lookin at?

Thanks for posting the pics, but there's very little that can be done to help diagnose from looking at pictures.

Let's take a step back and establish what's been done so far. I believe you said earlier that you have fuel; what steps did you take to verify that the engine is getting fuel?

Have you checked to make sure there are no obstructions anywhere in the intake that would hinder the engine from getting enough air?

Are all of the sensors plugged in?

In the fuse box, is the 15 amp EFI fuse making a good contact?

Have you messed with the ECU, and if so is it properly mounted and plugged in?

I jumped b+ n fp my friend hear the pump, i smells the gas when i cranks it few time so yea
Now i suspect i miswired the ignition coil so give me pix or which wires im suppose to connecting, due no sparks now.
I has replaced new fuses unnessecery but yea why not.
I has reconnected the vacuum correctly way.
Did check all sensor.
Got me new battery.
New 3 gallons of gas.
Starter system im leave it alone since it will crank everytime so focus at ignition coil wires here.. i mite misconnectes one of dem tjen sld able to get spark after i found a pix or sum1 tell me wat color the wires suppose be connecting thanks. Then it sld be my final question.

I have a friend with a 7MGTE waiting to swap into his Supra, I'll see if I can get out to his place sometime soon and check out the coil pack wiring for you. When you mounted the coil packs, did you attach the grounds coming off of them too?

[DawgB0]

Of course i made sure everything is well connected and earthed and yea they all are, i already tested all voltages n keep getting 12v means its connecting but no spark or i reLly does but wrong wire!! that y i need help by give me closer pix of the wires or just tell me off of any turbo mk3 jus lik my pix above
