Hey guys,
Hope ya guys can help me out. Pretty new to owning a diesel and I love them. Bought one as we go out west sledding and pull a 4 place trailer along with gear and it works great. So my issue is within the last 3-4 weeks my truck has been getting harder and harder to start. Yesterday it took forever to start after work along with this morning. Never had to plug it in. Just looking to see what I can check before I bring it in. I am pretty handy with tools. The truck is just shy of 200,000 miles. Any help would be much appreciated. Thanks Live in MN.

might need some glow plugs and a relay

Was kinda thinking that. Been reading onhere how to test and change them out. Doesnt seem to bad.

relay is super easy, glow plugs it takes me about 2-3 hours to do.

Where is the relay located at?

Passenger side of the engine

Thanks

I went out and looked for the relay but can't seem to find it.

Is there a little computer looking thing on the passenger side of the engine? Above the valve cover

I looked at some pics from Oreillys auto and from that pic of the part it looks like there are 2 of them on top of the motor on the passenger side.

One is for the intake heater, the other is glow plugs
