Engine Tech / No Run Problem
when it was running,the injectors were spraying?
and i get the same voltage on mine.

Let me try to answer some of your questions.
The red "engine" light is duel purpose, Low oil pressure or engine overheating.
Your car has no check engine light.
The red wire on the fuel injectors should be 12v with the ignition in run or start.
The EEC provides ground pulses to the tan wires to operate the injectors.
The EEC will only pulse the injectors if the engine is turning over.
The EEC knows the engine is turning over if it is receiving PIP pulses from the ignition module. (danzajax's procedure tricks the EEC into thinking the engine is turning over)

Jumpering 12v and ground directly to the injectors can destroy the injectors)

The shop manual method to test if the injectors are pulsing is :
1. Install your fuel pressure gauge.
2. Pressurize the fuel by doing several "primes" and confirm that it can hold the pressure with the pump stopped at a nominal 39 psi.
3. Unplug the fuel pump relay.
4. Crank the engine for 5 seconds.
5. The fuel pressure should drop to between 10 and 20 psi.

There is a specialized test light call a noid light for testing for injector pulses. It has connectors that match up to your injector connector.
Or you can make do with a regular test light that you can use for other stuff. (note, not a self powered continuity tester type light)

So off you go to the car parts store for a fuel pressure gauge and a test light.


now what he and I both need are the voltage checks on the ignition module to see if its sending that signal to the eec.
when turning over,what wires have what voltage from the ignition module.
I replaced my ignition module but would love to know the voltage outputs because my wiring is suspect also.old,corroded wires etc.

check ur voltage at the injectors.one injector has 2 pins.check one pin then the other with the key in the one position.should get 12v on one pin.have someone turn the car over and the other voltage should be 5v on the other pin
let us know

Here is a good way to check.  If you are comfortable re-seating/aligning the distributor.

Unbolt the distributor.  Pull it free from the cam gear but leave it touching the block (leaving the wires attached).  Remove the cap and with the car in run, rotate the rotor button (counter clock-wise).  The injectors should fire and the spark plugs should pop.  You should be able to get a good close look at the injectors firing.  When do it on my MPFI with the upper intake off, I can easily hear the injector spraying.

i may be wrong but on my 83,there isnt anyway for the dist to fire the injector.

even if u had really low pressure,the injector would at least drip.if the injector isn't spraying a dribble,and u know u r getting gas to them,its electrical.IMO
a good firing injector and weak pump would dribble gas.no injector pulse and you will not dribble anything :burnout:

check ur voltage at the injector clips.
should be 12v on one and 5 volts on the other.at both clips.
thats my problem.i have the 12 v but not the 5.i was told its either the ignition module or eec.i replace dmy eec,still no voltage.im in the process of replacing the eec.
u can also use jumper wires to see if ur injectors will spray.remove the injector clips,and give it some voltage.one pin will be +...the other ..-
turn the key to on,let the pump give it gas.do one injector.turn off car,turn back on,do other injector

dont do it alot,may hurt the injector.
try that,let us know if they will spray.

Body/Appearance/Interior / factory body kit?

There is no factory body kit...

well,whatever it is,ive seen this car since 1986  owe owner and it had this kit on it since new.

im having the same kinda problem.
im getting gas to the injectors but not current.i am getting 12v on one side,but not 5volts to the ground.
i can jump the injectors with a battery source and they spray fine.hook everything all back up..no fire at injectors.
i put on a new igniton module,still not injector fire.

Body/Appearance/Interior / factory body kit?
i have a 83 tbird and i have found a 85? near me that is wasted,but has the factory body kit on it.
will it fit my 83 or is it a waste of time?
