no power here i go again
how did it get from #1 to #2? That do make a difference, yessir! you will notice that your adjusted rotor position is the same as the pic I sent you -which points to #1 firing tab.
you owe gerard for figuring it out. in the future, you can help yourself -and maybe establish some credibility- by doing the simple things, like marking plug wires at the distributor.
If you would have followed directions this would have been the outcome long ago.

At the end i find out this was wrong. i have to align the rotor to the center of the engine. between 1 and 8 cap post 6 oclock position.
so in part i was under the belief that the rotor was ok at 5 oclock position.
that is why I thought that everything was ok.

after seting the TPS to spec the car is not working ok
I try to set timing using my timming light. and the mark on the balancer is way off.
when i try to rotate the dist cap clock wise to get the mark closer to 6* BTDC the rpm get so low that the car turn off
in order for the car not to die on me, the mark on balancer is way off . in fact out of scale
like a inch away from the last number on the scale btdc
i set tps to the correct numbers 0.45 close to 4.3 full open. did not get to 4.5 but i guest 4.3 is close enogh
here is a picture of the reding of TPS

[/IMG]here is a pic of the distributor the way it is now after reseting the tps. nothing like before

I dont feel number 7 injector clicking. if i touch every other injectors. clearly can feel the clicking. but not in number 7 injector.
I disconect injector 7 with the engine running. and i feel the change on the engine.
so one thing is telling me injector is not working, the oder tell me is ok.
I was planing on doing some more test on that injector. but iam going to the beach tomorrow and coming back on saturday. so may be on sunday. any way i will take my laptop to check the forum like always

Best and quickest way to check all your injectors work. (my new injectors are very quiet) so that clicking noise may not be a good indicator but you felt a change so it must be working.
From cold start the car and run for 20 or 30 seconds then shut her of, feel each exhaust header pipe about an inch from the head and check they are all the same temperature? and hot to touch.
I had a injector electrical connector that had a cracked metal strip, when it was unplugged and turned over i could see the 12 volt pulses with my multimeter but obviously it couldn't pass enough current to the injector. Now that was a hard one to trace. If you have a cold exhaust on no 7 then you will need to check the connector or replace it. Note if an injector is not working the engine will shudder under acceleration and feel like it is missing and have a lot of engine shake. Note loss of compression from valves not closing all the way can have the same symptoms.
You did disconnect the timing bypass connector?
It is a single wire plug near the fuel pump relay and windshield wiper.
You need to disconnect it and then set the timing, then re connect it for the ecm/spark retard to work.
The tps 0.54 to 4.3 should be fine and should rise gradually.
Have you confirmed you are getting good fuel pressure (at least 30psi)
Also check all your connections are good especially the mass airflow sensor and make sure there is no corrosion which will act as an insulator.
