P1300

So with these test I maybe would come up with haveing to replace the harness? The ignitor is fine I bought a brand new ignitor for 500 dollars didnt work. Or replace the ecm?

I work at a mechanic shop so I did put the meter on everything n the diagrams that showed. Everything seems to b working correctly in the wiring harness for the ignitor all voltage isin the areas shown. The only thing I saw funny was the ecm part im not sure if the car has to be running during cheack that or being cranked I tried it with the igniton just on like the ignitor part tells u to do. Funny thing happened after tryin to still crank it a guy that has his own shop down the road said tap it with hammer not hard just a tap as u are tryin to start the car. I did that and it showed five trouble codes. Well I erased them ond only the p1300 code came back the card did start but turned right back off. I decided to take the battery off charge it for a while and also just take the hole computer out. About two hours later I went back to it and plugged it all back up I hit the computer a lil harder this time because I was getting fed up and it started it ran till I closed up my shop so it was like 45 min I drove it about ten miles the coad did not pop back on until I let it sit running for about 10 min and walked back to it and erased it before the code would pop on at every crank I have a handle held n my had the hole time im doing all this also to erase everytime it comes on with all this being said I just really want my car to run do u think it may be the computer now?
