P500 Hard start cold

[25yrds]

It's the seat belt light, you must be latching in right away.

Yeah, hehehe, I plugged the passenger side into to driver side. Don't by any means advocate this but it's what I needed to do

Forum store has a bypass plug for that seatbelt if you like.

Yeah, once it starts once it fires immediately all day long as long as it doesn't get too cold. Doesn't bog. Actually runs extremely well once it's started. Heavy oil and questionable battery are what I'm thinking

Yep, I've seen it. For now this will work

Are you stepping on the brake paddle while cranking it?

Only time mine doesn’t start right up is if I’m to impatient to let the fuel pump finish. No trouble codes displayed? Frustrating. Under warranty, then call dealer? Following and thinking...

My battery is 3 years old and still starts fine, if I let the fuel pump get going first.

Mines an 18 with 300 some odd miles on it and it does the same if I don’t let the fuel pump cycle all the way. Long as I let it do it’s thing it hits right off the bat and tires right up.

Believe me, I'm letting fuel pump pump up. Even cycle it 3 or 4 times until I hear it stop. I'm an ASE certified (30 yrs) auto and heavy truck mechanic. I

No. Never heard of this. I'll give it a try

Only if it's in Gear you do this..I just found this out.Thought it had to be in neutral to start but you press brake paddle in any gear to start it...

2015, original battery, 10 degree weather this weekend. Mine would crank a little longer before catching but I wasn't surprised due to conditions. Inspect plug because it could be fouled from short runs at dealer if it was moved around every day but never actually run any length of time. New plug, full tank, excuse for a long ride. Don't forget what 'new' stands for, never ever worked.

My .02 on this is a tight valve, been there, done that with a 4wheeler before, same exact issue.

Oh, yeah, I knew about this.

Or just go with the “Original Contributor” Idea. Thanks @JTW. One of the early best mods on this forum like the box.

Ok. This evening I tried to start it. Cycled key on/off 4 times, 5 seconds between. Heard pump go every time. Cranked for 6 seconds and didn't fire a lick. Stopped, tried again, about 3 seconds in she "coughed" through intake and fired almost immediately and runs flawlessly, restarts quickly every time now, even though I shut it off second it started. 60 degrees. Sat all weekend without running. Tomorrow I'm gonna put a jump box on battery first thing, as I just don't think she's cranking as fast as she should, and see what happens.

It's a P5! HA! just kidding, what's the age of your battery, you have some pretty cold winters in Idaho. The battery in our P1 is a little over 3 years old and I'm thinking about replacing it with an Odyssey like my secondary battery. The original is getting a little slow when it's cold.

Many posts on how sensitive these engines are to even the slightest compromise of battery strength. Finally replaced mine recently after going down rabbit holes, cleaning connections, etc. Showed good voltage, but weak on actual cranking amps.

My suspicions exactly

That freaked my ECU out, so I stopped starting it in gear?
