So, you'll probably never believe this. After my last post. Bought four new plugs the day after. Installed them, car fired right up, ran, and sounded great. Let it run and drove it around the yard for almost an hour. It wasn't registered for the road yet at this point. I was waiting to get it running first.
So, three days later, car sat behind the house where I had parked it. I got the car registered at the DMV, got the plate, all good to go.
Day after that I decided I'm going to run it over to my friend's place who has a hoist, so I can get a good look underneath and check the ball joints, wheel bearings, tie rods etc. Just to make sure she's good and safe for the road.
She wouldn't start. After several failed attempts, I pushed it back into my garage, my first thought was to check the plugs, to my surprise, no fire on any cylinders. I checked all 4 plugs, and checked the coils with the spark tester, nothing. I have no injector pulse. And no rpm signal while cranking.
The fuel pump does run while cranking the engine. Swapped out the new camshaft sensor with the old one. No change. Crank takes time to get to. But from earlier testing it seemed the camshaft sensor was the one responsible for the tach signal. But not positive. The cam sensor, I tested the wires. 1 outside has continuity with ground, the other outside wire has 12v with key on, and the middle wire has 5v. If I back probe the middle wire with the sensor plugged in but removed from the motor, it gets 5v and it drops to 0v if I put a wrench next to it. So, I'm thinking the sensor is working. One thing, the cam sensor had oil on it when I pulled it. Is there supposed to be oil inside where the cam sensor goes? Also, while back probing the middle wire, I installed the sensor back. And put a test light on the middle wire, and other end to ground, the test light did not flash while cranking, but I'm not sure thinking about it now if my test light works for 5v or not, I'll have to go check. Are there contacts inside where the cam sensor goes that could have fallen out or something?
And I did recheck the compression, same as before, 210 across the board, so not a timing belt issue.
