Diagnosing intermittent crank no start condition.

Replaced oil pressure sensor and must have caused a short to open because when I fiddle with the wires behind the intake I can get the truck to start and run. In the picture attached I can see, from top to bottom, cam position sensor, oil pressure sender, and an unknown component that looks like a ground. It also looks like it threads into the back of the block.

1. What is this component?
2. Could it cause a no start condition?

Thanks for the help.

Here’s a picture from a different angle I stole

The wires from your camshaft sensor look bare, but maybe it’s just a sheen from oil I’m seeing

Any dtcs?

Agreed with @ks03. If wiggling the wire gets it to start there’s probably a bad connection or a short.

I agree, most likely culprit is cam position connector. I have another pigtail on the way, in case it is the culprit. No DTC present, which is weird because of the cam connector was shorting I would assume I would get a cam sensor circuit DTC.

The component that I am confused about is a large hex with a wire in the center, does not appear to be in your picture. Perhaps this component has been removed in later generations?

It's just a ground.

It's just a ground.

Do you know what ground it is for?

I see no issues with this

Just updating this. I soldered the new pig tail in and i am 99% positive that this issue is fixed. I haven't had any no start issues since last post.

Did you take off the intake manifold to do this?

I did not, taking it off will help with access immensely though.
