Starting isssues and spark knock Q's

[spudz29212MKIII]

yea I found out that its the cam sensor connect. Diagnosis would show no signals from it. Then jiggle wires, reset stored codes, start car, then do another diagnosis codes gone. Connector good just the wire attached looks shitty. hoping just a re-wire solve it.

I did not have the knock when I got the car like, 10 months ago. also no egr vac modulator. After i replaced that with a used from ebay maybe a few months later it started.

YouTube - Supra Knock? This is what is sounds like. Only between 2000 rpm and 3000 rpm

See now you're getting the puzzle pieces you need.
For every 1 thing you fix on these cars.
2 more things go wrong.

Sounds like you are getting close to the heart of the matter spudz.
For every 1 thing you fix.
2 more are surely to break.

The only way I can get a leg up on my car is to work 3 days straight on it with no rest.

Then when I do rest and come back, the supra gremlins had made well oiled use of their time.

thats what im afraid of. Especially since its the cam position sensor. If that thing messes up it can cause a whole heep of problems if not carful.

I had 1 thing go wrong and by the time I finished poking and prodding I have a list now.

It never ever seems to fail.

These cars cover up so well until they break.

OK, my next two cents goes toward a cam follower knock, that is, the knock sounds to me like it's coming from the head, not the block. Although it's not easy to diagnose from a video and because I don't know exactly what yours sounds like, I can't say %100 that this is the cause but if I were to bet, I would say it definately sounds like something in the head.
Since Supra cam followers are solid type and not hydraulic, only two possibilities arise, either there is too much clearence between the cam lobe and the follower or you may have a valve that is slightly sticking. If the valve is sticking you could try some marvel mystery oil. If clearance is the issue, you've either got a worn cam lobe or follower shim or a combination of two.

Of course, I could be totally wrong and you might have a bad piston pin.
In that case, time for a new motor.

its in the head, i know that, loudest at exhaust side valve cover
