#1028 of 1038 The new G8 GXP by jpstax1 May 01, 2008 (1:48 pm)
I found this link about the subject car:   http://www.caranddriver.com/reviews/hot_lists/high_performance/muscle_cars/2009_- - - - pontiac_g8_gxp_auto_shows.html   Hosts: Since I searched but couldn't find any forum for this car, I thought my post best belonged in this forum, or should I have created a new one and named it "High Performance Sedans"?

And you can get an m3 with four doors.   Not sure if the g8 gxp will be a luxury car...   Also, the new CTS-V now holds the record for fastest nurburg ring lap by a sedan with street tires. It beat the m5 by 13 seconds! Looks like they must have gotten the handling sorted out...
#1032 of 1038 1998 XJR - ran fine now will not start by jameshymel Jun 13, 2008 (6:52 pm)
We have a well kept 1998 XJR which we have been driving only once or twice a month. Today I drove it about 15 miles to work - it ran flawlessly. At lunch I took it out for a few miles (the temp in Dallas is approx 90 degrees) then parked it at the gym. After an hour I started the car and it immediately died. I tried again and managed to get it to idle, but roughly. It died. I could depress the accelerator but it seemed to have no effect. It would only start, run rough, then die. After an hour, it would only turn over and never attempt to start (the engine would never start running on it's own - even roughly). We had the car towed home and my gear head neighbor came over. He had me engage the key (turn it on, but no to start the car). He could not hear the fuel pump whine. We checked all fuses (those in the trunk) and even located and checked the fuel cut off switch in the passenger floorboard. How can I determine if an engine sensor might be disabling the fuel pump relays versus the fuel pump simply being dead?   Thanks.

Replying to: jameshymel (Jun 13, 2008 6:52 pm) Well, James, actually driving the car might've prevented this problem. A 10 year old car that's only been driven 20 or so times?? I can only imagine how much stuff is fouled/corroded in the engine and/or fuel delivery system. Once you get it fixed, you need to start putting some miles on that thing!   You can use a volt meter to check voltage at the fuel pump relay. My guess, though, is that you have a tank full of bad gas considering you've probably only filled it up maybe 3 times in 10 years, if that. Mix some octane booster, injector cleaner (might not hurt to throw a little xylene in there, too), and some fresh gas in with that old stuff, and change the fuel filter and spark plugs. Then when/if you get it started drive it until the tank's almost empty. On your way to the gas station, stop by an AutoZone, Advance Auto, etc. and pick up a can of Sea Foam. Head to the gas station, preferably someplace with Techron or other strong detergent mixed in the fuel (Shell, Texaco), poor in the Sea Foam, fill tank, and drive the car more often.

Replying to: tayl0rd (Jun 16, 2008 6:45 am) Thanks very much for your reply. I think I was not clear. The car was driven daily by my wife, but recently (for the past 4 months) it has only been driven twice a month (purely to keep things in check). The tank was down to nearly empty and so I stopped on the way to work and filled the tank. I then drove it about 20 miles and it ran fine. At lunchtime, when I started it, it idled rough then died. It would then never start. I had it towed home where we checked the fuel pump fuses (but not the relays) and the fuel cutoff - all seemed OK. My neighbor (a mechanic) said that when I engaged the ignition, he could not hear the fuel pump whine (to pressurize the lines) so he thinks the pump is dead. We have not checked the voltage at the pump to see if the relay happens to be dead. Note - I did change the battery just the night before as it had died. What say you?

Replying to: tayl0rd (Jun 16, 2008 6:45 am) Actually my Jag mechanic suggested I had water in the tank. Why I dont know. We keep it in the garage, and while we have not driven it in a few weeks - I can not think how it could be water. (Was it the full tank of gas I picked up that morning at a Shell station?) May I ask you - are the fuel pump relays next to the fuses in the trunk? I was also told (by another mechanic) that I can get to the fuel pump electrical leads by removing the trunk panels and I can check for voltage/no voltage there.

Replying to: jameshymel (Jun 16, 2008 7:12 am) Yes, I believe on all Ford and Ford owned companies, the fuel relay/shutoff/reset is located behind a panel (or the liner) on the lefthand side of the trunk. You'll know it when you see it. If I recall, it is black with yellow writing and/or a yellow switch on the top of it.
