You guys are great. I feel dumb cause that was such an easy fix and I missed it for 4 days even after checking many times and all. But oh well, learn something new everyday. Stay good fellas!

It The new sensor was from advance auto. They look identical but the o-ring is just barely too big for the hole. Very very hard to catch. I just happen to notice it. I don’t know the brand off hand but if you go to change it, just make sure it’s fully seated and you’ll be fine! Thank you...

I FIGURED IT OUT BOYS!! After 4 days, many hours and a lot of words. The cam sensor, for what ever reason, did not seat fully after the many times of it going in and out for test starts. I put the new sensor in and noticed there was a little gap, and by little, I mean micro. So out with the new...

Sanded down the cam sensor port to bare metal. No change

The tach does move on start up attempts. Basically the car acts like it wants to start really bad but just won’t. If I had an accessport I would be glad to upload logs or anything helpful but I haven’t got around to ordering the port. And I don’t have a computer for logs either. Which would make...

VTCS is all good, checked that last night. Haven’t got around to doing the delete on it. And I traces all the fuel lines both HP and LP to be sure all was good and they are.

Yeah, blowing you guys mind too huh. I get off work at 11pm est, I’ll head back to my garage and sand down the sensor place again, hook up the battery charger to make absolutely sure that it has charge, add gas in the tank to be sure it has gas and make another attempt at starting. I’ll grab...

Also tried to choke the car and start it, (block the intake from pulling air to get fuel to flow better) that got me a more consistent attempt on starting. (Every turn over was catching but only for a split second but lead to nothing again) I checked the plugs after doing this to make sure I...

Yes, occasionally it will catch for a split second but nothing happens. And their is a fuel smell from the engine bay. Not sure about from the exhaust. It’s just me trying to do this alone so it’s hard to catch everything

Cam position sensor, the one that sits on top the valve cover.

The only thing I forgot to mention in the original post and this whole time, I cleaned the air filter as well. It’s a full Cobb filter set up so I followed their site on cleaning it with their kit (‘soap’ and oil) but it won’t start even without it on.

Spark plugs are the same brand and gap as the old ones, plus won’t fire on the old plugs either. Pretty sure they are Denso Iridiums because nobody around me carried the ngk so I’ve just been running the denso’s. As I said, same plugs the car already ran on

Same size intake as it was when I parked it to do the job. Nothing is new, ran when I parked it now it won’t

I’m not sure what pictures are needed to help you guys out, there is spark, I tested by just pulling the plugs and placing them in the boot to see spark, they all work. Tried 3 sets of plugs to be sure. All the fuses are good and checked with a multi meter and as stated in the starter post, the...

I have read all your replies and I have tried each and all of them. No codes, reconnected all wires many times along with checking them with a multi-meter to make sure they have power. As stated, all screw holes on the valve cover have been taped or taken back to bare metal, the sensor in...

Update: HPFP is grounded. Still nothing

Thank you, I will check that tomorrow and update!

For note, car isn’t throwing any codes either.

2012 Mazdaspeed3 So, I park my car in my garage to do some maintenance. 1. Change valve cover gasket 2. Change Plugs 3. Change oil and filter so, first thing first, I disconnected the battery just out of habit. Pulled the plugs, then valve cover. Replaced plugs, and taped off and put a coat of...
