I'm officially a stupid blind roockie:eek: I unscrew the vacuum for brake pump....

I apologize.

The correct inlet is on driver side(I hope),the line with a sort of "bleeder".How it work?
I presume is to push out the air trapped in the line? can someone confirm?

Thank you.

I answer to my self:
It's a air bleeder,take of the little cap and push the spring in the middle with a small screw,a lot of air come out,crank the engine and do same thing,now I have the fuel coming out.I'll try more time and try to see if the injector become wet,if not i find the guilty.

I can confirm,using a really small screwdriver to push inside the bleeder,the air comes out,you need to push until the fuel comes out.
Today a learned something of new !
Now the problem is moved on the injector.
I hope step by step to put the lady back on the road again but I'm not in hurry.

Today I cleaned the injector,soakng in the WD40,now I can hear the click using a 9 volt batterie.
In one injector connection cranking the engine I read 11,9 volt,in the other one just 2,9.
I have disassembled the fuel pump regulatoris necessary any sort of "setting" with this brass float?I found all screwed up,I try to start the car with it in half way,but nothing.

During the injector disassembly I notice difference in one of it(passenger side) is lost/broke the ledge,this can cause a lot of fuel dropping down?

I try to start the engine many times dropping some fuel direct on the body,and I had a huge back fire(I don't have chenged ignition timing order)just checked the rotor cap,the back fire come from the driver side,next a have the same thing on passenger side but just smoke.
Maybe a lot of fuel dropped in the engine?

Can a bad fuel regulator cause this thing ? the "check engine "light is on.

:eek: opsss..

I noticed too some fuelleaking in the base of TBI,maybe the surfare is not straight,no more !
I think I need to buy the the complete thottle body,is the way to go.If I compare the cost to machine the body,2 injectors,fuel pressure reguator,TPS and all gasket I don't have a big difference !

Another strange thing is the difference of voltage in 2 injector,I thing the work in the same time at idlee too,but I can understand this huge difference(11,9 to 2,9).It's possible they work in the same way to carburetor and the secondaries open with vacuum and not meccanically?
I want to check the wires from TBI to firewall.
