What is your question?
I had a intermittent starting issue (crank no start) that seems to have manifested itself into a no crank no start. When this first happened I jumped it and it slowly started and ran. I got the battery tested and it was bad. I replaced the battery with a new one that was tested and proven good. Once I put it in the car, it still started slowly but ran and drove. I shut it off and left it for about 3 hours. When I came back and tried to start it, it cranked but seemed to gradually get slower then completely stopped. No crank at all when I turned the key. I checked battery voltage and it showed 12.69v and tested good again. I probed the yellow wire from the ignition switch with a test light when the key is in the start position and it did light up. Hit the starter with a hammer with no result. I switched relays around but still nothing. Crank relay has constant and cranking voltage. Fuses are good. Check engine light stays on in crank position. Any help is appreciated. Thanks.

Hello, Check the ground for the battery, and make sure the cable is good, has continuity, and is clean and tight at both ends. Then, do the same for the positive cable. If the cable runs to the power distribution box before it goes to the starter, add that into your list of connections to check. The battery cables should have nearly no resistance from one end to the other, and corrosion can work it's way up from the battery terminals to underneath the sheathing on the cables. The battery checking at 12.69v is great, but what does it read while cranking? Same at the starter, what is the voltage at the starter while cranking? Sounds like the issue is in delivering power to the starter.
