Alright, this is long but I am trying to give all the details, not sure if some of these things relate. But I will say all of it and we can go from there.
Had a Outlet fitting on the HPOP leaking. The night I found the leak I was trying to see if the cut out between the two fittings was actually a hole that had gotten punched in the pump. So I grab a long screwdriver to probe(no jokes here ) the spot to see how deep it is. While I was doing this I accidently rubbed the screwdriver on the cable going to the alternator. As I am sure you already guessed it a large amount of sparks insude. Enough that it caught me off guard. I dropped the screwdriver which wedged itself in place and starts to glow cherry red. I tried to get it out but no luck. Next thing I know if there are flames from under the hood. I grab the fire extinguisher I keep under my seat and get the fire knocked out quickly. Thankfully the screwdriver actually melted in half and fell away from the cable. So after blowing 2 pounds worth of dry powder off the engine I survey the damage. I think I got really lucky and only saw a small section of wire loom burnt. I inspected the wires and didn't see any damage. So I replaced the loom. The next day I go to the dealership and get the parts needed for the HPOP fitting leak. The fix goes well and am back together in just a couple hours. Drive the truck to work and it seems fine. I drive it today and have noticed that it seems to be struggling a lot at first to turn over. Like weak battery's or something. But it always starts. Also when I stopped at a stop light I have an idle variation. It is going up and down around 75-100 rpms. I have looked under the hook for any loose wires. I am at a loss.
What is causing the rpm to go up and down?
Why does it seem like the truck is hard to start all the sudden? (Temps have been in the 50's at night)
Batteries are two year old INTERSTATES, glowplugs and injector o rings next week.
I didn't see this until now. Are you asking after the night/first start up? Or anytime. After driving the truck for about 30 min this morning it was reading 14.6 at idle. Off batteries were sitting at 12.6. I did test the glowplug relay the other day. I replaced it with the larger one a lot of guys do. Going into the glow plug relay was 12.6. Coming out was 10.5.
Altenator line to the HPOP. I have a pic of the melted screwdriver . There is just an ark mark on the back of the alternator. That's it.
Somebody help me with this one. There aren't any alternator lines to the HPOP that I know of
There is EOT sensor, IPR, and EBP around the front. Show us the screwdriver pic. Unless it is really tiny, I don't know that any of these have enough amps (fused) to melt it.
The only thing I can think that I did different was take out the check valves on the HPOP? But everybody was saying that they didn't do anything anyways. I am totally at a loss.
Sorry, you can't hear much over the turn signal. When it goes up in rpm it runs rougher, when it is down it runs smoother. I know this all sounds crazy to me too.
This is all I could find for burn marks. Have a couple spots on the alternator. Then the small piece of loom I replaced. And the hole between the HPOP fittings is where the screwdriver was.
