Factory installed remote ENGINE start option.??
my 2005 to 2010 service manual shows no such device.
Flashlogic, after market bs? that?
or this (later it was an upgrade) per below.
so, does car start, key in ignition? that be like first.!!
does it?
if yes, then next is to look at the cluster for evics display errors.
better is to scan to pcm and see why,
if the magic is broken, scan it, or get it scanned.
on factory cars the remote start is very strict,
and it will tell you why it fails.
is that Another key , real, came with and worked before.
the keys must be married to the PCM./BCM for them to work.
scan it

find the guy who installed it and get them to make it work.
we cant guess what is installed in your car
find a live human that can look and see that, see first if
it is factory kit or aftermarket
they do not work the same, so.......

Oil pressure guage was working fine then just quit working altogether truck does idle rough could it be a problem with ignition sensor truck sat 6months

Did you change oil before starting after sitting 6 months? Oil goes bad just sitting, because moisture condenses in the oil pan, which leads to acid formation that can etch main and rod bearings. Best advice is get a mechanical oil pressure gauge and hook it up where electrical unit is now to check if your oil pressure is really low or not.

Where is the radio fuse located in a 2008 Jeep Grand Cherokee? My radio quit working and I can not figure out which fuse it is.

check the fuse box pull out or look to see if one is broken i'm not sure what type of fuses you have but if they have a metal wire inside and the mestal wire inside is broken then the fuse is bad and needs to be replaced .take the bad fuse with you to the auto parts store and match it up.some radios have a fuse in the back if you find out that it is not a fuse it could be a relay.also in some cars when you open the fuse box it will tell you what each fuse operats. good luck :)

Remote start problem triggers check engine light

The factory remote start system is designed to not function
when ever a check engie light is illuminated. The issue would have to be diagnosed by dealer and repaired. The remote starter should work again after repairs.

2000 Jeep Grand Cherokee Electrical Problems

Sounds like the ECM....the computer that controls all the electrical functions on the car is having some major issues or needs to be replaced. A auto repair or auto parts store should have a diagnostic machine that will tell you for sure or you can purchase one for between $50 and $150
