2001 WJ electrical issue
Ok, first off I want to apologize ahead of time as this post may be slightly long to explain issue:
Extremely proud owner of a 2001 WJ Grand cherokee Laredo, this vehicle has not had any issues in its life! Wondering if my luck has ended.... Ok, so the problem started a few days ago, I drove to work (I only work 1.5 miles from the house) Everything totally fine. Im a driver, so i returned from my route and went to head home, heres where everything goes south. I opened the door to leave and hear a clicking the second i open the door, then notice that none of my interior lights are on like normal. Go to start my jeep, and nothing! No click, no notta. Tried to jump start it to no avail. Anyway i left it at work and had the wife drop my off the next day, so when i finish i said, what the hell, ill go check it. So i open the door and low and behold, no clicking anymore and all interior lights are on (faintly). Tried to start and did get the clicking, so we jumped it and now it wont stay idling without throttle applied, even when pulling upto stoplight/stop signs. Get it home and my buddy who has been a GREAT mechanic for me for about 15 years+ started the trouble shooting.
((Had this abbreviated problem before and thought it had a bit to do with my negative terminal on my battery was TOTALLY corroded away, he replace the ends and we got a brand new battery just to be safe. didnt have the problem again for a cpl months(so we thought it was fixed))
With the problem coming back, we new it was nothing to do with the battery so with its age, i didnt even check, i just had him replace the starter. Still problem, so he wanted to get the Alternator checked, so we took it to 2 different parts stores, both cleared it with NO issues. He put it back on and has sat in the driveway for 2 days.
I have gone out periodically to check it and it is still sporadicly 1) clicking when door is opened to start with no interior lights and nothing when trying to start. 2) open door no clicking all interior lights on(faintly) and clicking when trying to start. Then jump start it, no throttle applied it will idle for a few seconds, then just die. wont start again without jump start and then dies over and over. Apply throttle after jump start and it stays running (did this for 30 min, lol) then let go of throttle, fell down to idle rpm held for 5 secs'ish then died again.
My poor buddy is getting very frustrated, so just looking for some possible help to get my baby back to tip top shape.
*Starter replaced, Alternator tested and GOOD, Brand new battery, new fuel filter also replaced 6 mnths ago. He just brought up, possible vacuum scenario.
Just looking to see if anyone has seen this issue or has any further suggestions, if anymore info is needed to help diagnose please just holler. Im in serious desperation mode, please helppppppp!!!!!!!!!!!!
