My Marauder is alive after 3 years of being dead......

[TonyD]

I finally got the reprogrammed computer and in the package was a sheet that said to verify the plugs or coils were not the cause of the prior computer failure. So I ordered new NGK plugs and coils from rockauto.
so when they arrived I started on the passenger side and they were all okay. The driver side was not so good. The first one towards the front was a little oily but no concerns yet. It went downhill real fast from there. The rest were beyond juicy......the socket and plug both came out dripping with oil.....oh did I mention the second coil was completely melted and the spring and most of the coil pieces were out of the hole. The same plug as the melted coil was barely even hand tight. I needed assistance from this point and had my mechanic buddy look and he said most of the threads were missing. He got the new plug in and we kept going. The back two plugs were completely under oil. But we got it all back together. I asked if I should order a new valve cover gasket set but he said to let's wait to see how the motor starts to see if it's still going to be savable.
couple days later the locksmith came out and programmed the computer to acknowledge the keys and it started immediately but they only let it run for a few seconds.....I was at work.
When I got off later I started it and yup it fired right up and the self leveling fired up and the rear came up. I have a weird thumping noise coming from the dash possibly an hvac issue.
the motor idles okay I don't think it's ticking or a rod....it sounds like an exhaust leak or maybe a bad cat....and I would assume really really old bad gas.
it has oil, coolant is low...oil looked okay. I have new tires for it once I can drive it and I called the dealer and the car never had the lighting recall so I'll do that too.
any thought.......

Don't do the lighting recall, they'll butcher the wiring harness.

Have FBM or someone upgrade your LCM. = FAR better way to handle the problem.

I agree do not let the dealer do the fix! I am out of modified LCM's so I cannot help. Good luck getting in touch with fastblackmerc I haven't had any.

Pull the covers and reseal the top of the engine. Have You done the timing components? Surprised the fuel
Pumped worked after sitting that long. Replace the fuel filter and give it some fresh oil and coolant. Burp the system. Good luck!

I'm bringing one back to life after sitting over 5yrs. Can't wait!

I have a weird thumping noise coming from the dash possibly an hvac issue. EATC blend door actuator failing? Run the self test as prescribed here: http://www.idmsvcs.com/2vmod/eatcswap/selftest.html

What is a modified lcm? Modded in what way?

[Agent2006]

How low on coolant, and why?

Compression check would be my next move...

The relays in the LCM are too small for the amperage going thru them which is why the LCM fails.

A modified LCM has had the relays replaced with stronger ones.

I didn’t know this was a thing. Good to know. Thanks.

So do you just open the bad one and replace all the relays, is there a thread I keep searching using the search box but I must be doing something wrong

I still can't get it to pass a smog test but I'm still trying. I've replaced the heater door blend actuator, replaced the resistor and the blower and now all that works. Replaced the drivers rear door that was dented and now I just need to fine tune the actuator cause it's sticking. Replaced the bulbs in center gauges....But when I try to smog it, it keeps coming up with a lean bank 2 code, we smoke tested it for like 30 minutes and didn't see any leaks. The reader says fuel pressure is right but when we put a gauge on it, it drops way down so they suspect it's either the pump or a bad fuel injector. I bought both but can't find a video or a how to on how to do the injectors. On my 5.9 Durango it's a 15 minute job but any help would greatly be appreciated since I have never taken my marauder apart yet. Figure maybe do valve cover gaskets at same time and maybe intake gasket? I've searched on the forum but don't see anything specific regarding how to replace...
thanks

Or do what I did I wanted my lcm to remain stock as from the factory no updated or modified stuff, so I just got a headlight relay kit upgrade so all the headlight switch does now is activate a 40 amp relay way less draw on the lcm relay and a little bit better voltage to the actual headlights. No cutting any factory wires and removable with no trace.
