Based on this more detailed report, I wonder if the problem is co
incidental with the oil change. I would start by checking the battery
terminals; then checking/charging battery.
As Grahame suggested a load test would let let you know if a new battery is called for. If that’s not an easy option a nice long trickle charge would be my next step. How 'bout taking the battery to a parts store that offers testing, before you buy a new battery that may not be needed?
Seems all “modern” cars are very sensitive to incorrect voltage and their
computers will exhibit any number of odd behaviors; including triggering
spurious warnings. So I’d forget about the engine light unless it returns.
I, too, have a no-start problem with my 2002 -type 2.5, but it’s intermittent. Battery is nearly new, but one day i set off on errands and after 2-3 stops and restarts, when I stopped for gas the engine refused to turn over, barely a click. AAA tech tried jump start to no avail. Towed to mechanic, not import specialist but competent and thorough. They found that the car started OK, spent time checking to try to find a problem with no result. Took car home, and after 2 weeks normal driving, it again refused to turn over or start, while I was ten miles from home. It’s now in my driveway, has continued no-start behavior. I’m thinking that relays and fuses associated with starter should be double checked, but has anyone experienced this pattern, or have suggestions for other trouble shooting? I’m hoping to get a friend/mechanic/Jag owner to do a brief home trouble call before I have it towed anywhere else. Thanks for any new leads… Jim Poole, Ft. Collins, CO.
