Hello All,
I searched the forums for some time and tried most all suggestions but nothing has worked. I've gotten to the point where I almost want to sell the damn thing.
Vehicle Info:
2001 XJ Sport 2WD 4.0L AW4 217,000 miles
OEM CPS is only 10k miles old
NAPA TPS and IAC Sensors Brand New
Battery is New
Alternator Tested Fine
Cables and Connections tight and clean
Fuses look fine
Symptoms:
Initially wouldn't idle without pressing on gas, now doesn't even crank just one click.
Long Story:
So back in the summer it started not wanting to idle all the time. It would start just fine but without holding the gas it would just die. It was far and few between but I did do my best to fix it. Initally I changed my battery out, as it was pretty old and came back not holding a great charge. This fixed the problem for some time.
Then two months later it did it again but with even more symptoms. First it would start and run just fine then on the highway the "check gauges" light came on and the Voltmeter spiked to the highest it could go. Then all the guages died. It ran fine and has never happened sense then.
A week later it started just fine then would die if I didn't hold on the gas. So I figured, "check the alternator". I pulled the alternator and got it checked by 3 different places multiple times. Everyone said it was fine and not the issue. I hooked everything up, cleaned all the connectors and insured the cables looked good; It started right up and idled fine.... now I was thinking, "sensor or bad ground somewhere".
I went ahead and pulled the gauges, and my aftermarket radio to insure nothing was grounding out. Again, everything seemed fine. I checked all the ground straps under the hood and insured they were clean and tight. This fixed it for a week (I assume because I had the battery disconnected and for no other reason) then it started doing the same thing.
I did a lot of research on the forums and found that a bad IAC and TPS could cause similar symptoms. I went ahead and bough both and threw them on. It worked... for a week.
Then last weekend I went to drive it and the same thing happened. Started but wouldn't idle.:flamemad: I was pissed so I just held the gas with one foot and braked with the other. That worked fine. I got home later that day and packed for the airport, as I was leaving town. A few hours later I hopped in and tried to start it. Initially it made some clicking noises from the relay box under the hood but didn't start. Then it did nothing, no clicking, no nothing. Still had power in the ON position but other than that it didn't even think about starting. A few days later my wife called me and said she tried to start it and it started right up!
Today I hopped in and it wouldn't start again. I checked the fuses and relays. The fuses seem fine but not sure how to check the relays. Maybe it's the starter? I'm frankly tired of throwing money and time at this issue. Has anyone heard of something similar? Anything I'm missing here that could be the cause. I'm about at the end of my rope. Thanks for reading and sorry for the book.
