Hello,
I got the connections figured out on the OBD Making sure I had a positive connection this time. What I was doing was performing a function test with the continuous flashing light. So I now routinely get a 1 1 1 no problem . Tried 3 times always the same. Good.
Following the green book, I was taken back to checking for spark .No spark with pulled plug grounded on head. then taking the HT wire off the cap from the coil and running it through a plug grounded on head we see a good spark. The book says and it makes sense the problem is with the cap or rotor. I have tried 3 different caps & rotors , I had cleaned the ground to the head. and still no spark through the cap but a good spark just through coil to cap wire. Tried wires and plugs from another running engine. Rotor turns .( I could handle a trimming belt. joke) injectors firing with fuel pressure.
I guess I will turn to the ECU with the thought that the spark from the coil alone
is false hope. Any thoughts would be appreciated. thanks ,Steve
