Default 2005 Accord PGM-FI Relay location help needed

I'm dumbfounded. I can't find my PGM-FI main relay in my daughters 2005 Accord. Some internet pics show it under the left dash, some show it behind the glove box. one showed it behind the kick panel. I've gone all thru the under-dash, and I can't find it anywhere. Someone please help.

What is the reason you're looking for the relay?

There is a PGM-FI Main Relay 1 and a PGM-FI Main Relay 2.

PGM-FI Main Relay 1 is FI Main.

PGM-FI Main Relay 2 is the fuel pump relay.

They are located in the under-dash fuse/relay box.

I'm searching for the bigger "main relay" that's "somewhere" under the dash, not the small ones in the panel. The car starts and then immediately dies. I've read this was either the ignition switch or the main relay. I've replaced the ignition switch, so now I'm searching for the main relay, and can't find it.

It doesn't have the older style main relay. What I previously posted is what is used on the 2005 Accord instead.

gotcha, so that explains why I couldn't find it. Now, I've replaced both small PGM-FI relays in the panel under the dash, and the ignition switch, and I still have the same problem. The car starts right up, and sounds good, then dies in about 2 seconds. Any ideas?

Is the Check Engine Light on? Any trouble codes?

It can be due to various reasons, such as timing, fuel issue, etc.

I got it figured out!!! woohoo!!!
If your car starts fine then dies about 2 seconds later, like mine was doing, I may have the fix for ya.

I replaced both PGM relays and replaced the ignition switch... none of that helped...

RESOLVED: I had a dead bug carcass stuck up inside my mass air flow sensor!! Dumped the dead bug out, sprayed with some MAF spray, and car runs perfect!!!

Check for dead bugs in your MAF Sensor!!! Hope this helps someone else.
