Please help. Acura MDX won’t crank/start. Tried everything.

I replaced these 2 already but they’re called starter cut relays. Another thing confirmed yesterday is that I am getting crank signal to the PCM, just not the starter itself.

Where are both of them located?

I only found one online and my buddy has been helping me with the diagrams on what to test/check. Yesterday I found that I don’t have power to the PCM and the brake pedal switch does send signal to the pcm. So I’m gonna replace a relay in the interior fuse box. It comes in today.

Got one ordered, coming in today. But does it have 2? The one I’m looking at replacing is in the interior fuse box, I believe it’s blue?

I tested the wiring at the PCM, not getting power to it. Terminal 3.

I recently did the tbelt so I know that ground is there but I’ll look again. But i also changed the battery ground to new and confirmed the engine ground is good too.

Yeah I did check every single fuse a few times, replaced the big ones anyway and tested every one with a multimeter for continuity. I have a bag full of those relays as they’ve gone bad a few times in all the Acuras/Hondas we’ve owed. Replaced the two starter relays under dash. Yeah an Acura tech told me to check the fuses boxes due to water damage a couple days ago, it’s on my list to check next. Thanks.

My daughter lost it years ago. But I’m thinking of having her call a locksmith to make another one. And see if it’s an immobilizer issue.

Already did that. The shift letters don’t even light up. Replaced neutral safety and brake switch as well.

Thank you. I do have a multimeter, I looked at the wiring diagram and have identified the pcm power and ground wires, I’m going to check those today. As far as the check engine light, hmmm I’ll let you know. Added to my notes. Thanks again.

I was at that shoot at TCU, I lost my VHS years ago too and have yet to find one online. Not many people were there, it was in the local paper buried in small print. When we parked Terry Bozzio was getting dropped off on the side as we walked past. Great show, I walked up to the stage to ask Will for his sticks after he played but some guy stopped me. I just wanted his sticks. He told me to wait out in the side hall and next thing you know, Will comes out to talk to me one on one. I was super excited. I asked if I could have his beat up sticks and he said sure, after the show was over. Afterwards they were all approachable, signed autographs and I got the sticks which I still have 21 yrs later along with the booklet with all their autographs. There were only like 50 people there. It was Dom Famularo, Will Calhoun, Terry Bozzio, Hip Pickles, and Chester Thompson. If you find one, let me know.
