Honda Mechanics Here? Solve this problem please04

04 Odyssey, 205k, Sometimes she will crank/turn over, but will not start. Sometimes she will start after many attempts, sometimes she will start after a few hours/over night. I drove this morning but this afternoon, she won't start. I am thinking either fuel relay or fuel pump. This problem first started like two years ago but recently happening more frequently. Anyone care to guess?

^ just wanted to add. Once starts, it stays on. It hasn't failed me while driving.

How does she run once she starts? Rough?

Not rough but sluggish but it’s 18yo/205k so it runs like one. This morning she turns over again. No hesitation at all. So frustrating.

One time I took it in, my mechanic said no code was coming up snd I will have to drive until it breaks down. How do I even explain this to him?

1) relay
2) battery test/replace - also check ground cable and connections
3) starter before fuel pump
4) fuel pump
5) sell to me for $1500.

could it be a key problem? sometimes key cylinders wear out.

My vote is starter

No issues with inserting and removing key. When I try to turn on, she cranks hard like it wants to turn on but having issues with actually starting the engine.

I replaced starter like 5 years ago. I don't remember if I've ever replaced fuel filter. I know I have never replaced fuel relay.

I am also thinking relay. Battery is strong and connections look good to me. Starter was replaced about 5 years ago. Fuel pump, maybe, I am not hearing any sound from the gas tank.

For your number 5, let me get back to you. LOL. Good day bud.

Go to Autozone and use their diagnostic code reader

If it cranks, it’s not the starter. That’s the starters only job, to crank it.

I ordered a relay switch and will replace it when it comes. i hope it fixes the issue. thanks all.

Our 01 Odyssey had a bad power cable between the battery and starter. Their are hundreds (thousands?) of wires in your van but the really high current wires are between the alternator, battery and starter. Should be checked.

Do the basic starter check at any auto parts store or shop, where they quickly check the state of your battery, alternator and starter. I once had a starter motor that mostly worked but was drawing four times so normal amount of current and was killing the battery.

Before replacing the fuel pump, replace the fuel filter if your van has one. My ancient Subaru was showing signs of a failing fuel pump but we saved a bunch by replacing the fuel filter that was clogged.
