Hello, this is Bob. I will do my best to assist you.
I assume that the distributor shaft is turning, correct?
yes it is
Do you have a test light or a volt meter?
yes I do
I have voltage at primary side of coil
Ok, do you have power to the igniton module?
Also do you have battery voltage to the red wire that goes to the fuel injectors with the key ON?
yes I have voltage at both with key on 11.87 volts
There should be battery voltage at the igntion module red/light green wire with key ON. in the diagram I traced the power flow in red and the blue should have battery voltage when cranking the engine over.
Orange/white wire should have 5 volts with the key On. Do you have that?
the color code on the schematic does not match what I have on this auto,top to bottom looking at the module connector installed I have : 1) Blue
1) Blue 2) Yellow 3)Red/purple tracer 4)Red 5)Yellow/Blue tracer 6)Black #5) Yellow/blue,has 11.87 volts key on, 4.87volts cranking
If wire colors don't match then use this diagram.
Your battery votlage seems low, can you charge the battery?
The red/ purple should be hot when cranking the engine. You have power to yellow/blue which is the run circuit.
Also check to make sure the ground to the ignition module is good.
Ground is good at module,I have power during cranking on the red/purple
Are you checking for spark at the coil or the spark plugs?
Also did you check to see if you have 5 volts at the orange/white wire at the throttle position sensor with the key On.
checking at coil, voltage at the orange/white with key on is 1.17volts
What about voltage on the orange/white wire at the throttle position sensor, you should have 5 volts with the key ON?
Trying to see if the engine computer is powered up and sending out vloltage.
at coil, so i need a PCM/
Just trying to see if we missed something. So you have no spark at the coil wire, correct?
You said you check voltage on the orange/white wire at the coil, I asked for voltage on orange/white wire at the Throttle Position Sensor, which should be 5 volts. Did you put coil in error instead of TPS?
