Hot Start Issue - 99 XK8

![Default](/forum/images/icons/icon1.gif)
Hi everyone! Just pulled my XK8 out of storage about a month ago and have been enjoying it ever since!
However, today I had an issue that seems to be repeating. This morning it fired up immediately. I drove 45 mins to work and it ran FLAWLESS. I pulled over to get coffee and when I returned the car wouldn't start. It cranks and cranks but it won't turn over. I tried for 15 mins or so with no luck. I sat in the car for another 10 mins without trying then finally tried one last time and it immediately fired right up. As if nothing was ever wrong! From there I drove it to the office without any issues.
I drove home without any issues at all and again, it performed FLAWLESS. After I parked it in my garage I tried to start it again and again, it won't start.
Any ideas or thoughts here?
Thanks!
Jay

I have had this happen once after sitting in 100+ degree stop and go traffic for over an hour and stopped for about 5 minutes. No start and the failsafe mode message. Waited about 5 more minutes and it started right up. I speculated that the standing coolant temp was too high to let it start. That's when I got Realguage. Don't know if that helps but, that was my experience.

I do not believe that there is any circuitry in the car that will prevent the engine from starting or running too hot. On the other hand, something electronic on the engine might have malfunctioned from excessive heat, such as the electronics in the throttle body or the MAF sensor.

Update -
Took the car out today and drove it for about 40 mins. Got home and turned it off. I waited 1 minute and tried to start it. No luck. Just turns and turns but no fire.
I wrapped a napkin around the schrader valve and depressed it with my key. Fuel shot up 3 feet in the air!! However, after doing that a few times the car started up.
Is my FPR shot? I'm lost... I'd hate to blindly take this into a mechanic and have someone randomly throw parts at it.

Hi Gus. I tried your suggestion and unfortunately it didn't work.
I took the liberty of making a short video of what I'm dealing with. Please take a look and let me know what your thoughts are.
And here's a follow up video shot 15 mins later. Car starts with no issue.

Thank god for the new battery! If I had my old one in there I would have been stranded with all of the starting attempts. At least now I know to just wait it out until I give it a try.
As for the warnings, the Traction Control and ABS lights are related. I was told by my mechanic that if most likely need a new ABS computer. Easy enough fix...
As for the rear bulbs, last summer I discovered that the previous owner hacked the wire loom in the trunk. Rather than replace a faulty socket he cut into a live wire from the opposite working side and jumped it over to the bad side. Such a ratty move.

To clarify, there are two fuseboxes you should do this to, the passenger side near the windshield and the driver side near the headlight.
