Scotty, really enjoy your youtube channel. Listen I have a 2011 MDX, 140k miles. I am original owner. Acura rebuilt pistons under a huge recall due to oil slipping past the rings. Runs like a top, except, theres a delay in fuel delivery when turning the key. Mechanic suggests it’s something in the fuel pump which is in the tank. I believe the filter is in the tank also.

Installed a new heavy duty super duper battery also. Fancy one from battery's plus two years ago. No change.

Insert Key and start, chugalug - struggles to get fuel and finally starts.

or

Insert Key, wait for fuel needle to register and noise from pump, then it starts fine. Turns over perfect.

If I use the dealer installed remote start, it turns over fine also. That seems to replicate the pause/delay.

Sometimes I can hop in and start no problem. Cold. 

Worth Mentioning - I have a strange ticking sound from what sounds like a relay or motor on damper under steering column, seems to only happen in spring and fall when AC or heat is flipping back and fourth. Click click - Click click click. Hear it at stop lights.

Oddest of all, if I put my fingers to the screws on the back of the steering wheel, I get shocked. Little zaps.
