OK, I am having a problem with my 1UZ-FE in my Saker SVS and I can't figure out what it is. Lets see if you guys can help me figure it out.
My car seems to "run out of gas" after driving it for a while. I trailered my car to the drag strip with a full tank of gas. I drove it out to tech inspection where it idles for about 10-15 min. When I pulled away gas came out of my overflow, which doesn't go to another container as it just goes straight out of the car. ( i think I over filled it when I put the gas in it though.) I did 3 runs about 10 min in between, then did another 2 runs with about 40 min in between each run. In between each run the car was just sitting there NOT running. When I went to start the car to put it back in the trailer it would NOT start and if it did it would just stall out. I tried keeping the throttle open when I started it but that didn't work either. So we pushed it back to the trailer. After 20 min or so I tried to start it and kept the revs up and it worked but would NOT idle as it woudl stall itself out.
Then I took the car to the road course and ran it hard for about 10-15 min. When I came into the pits at slow speed it just died. I started it immediately while still rolling and was able to keep it going if I kept the RPMs up. When I got to the pit garage I immediatley opened up the engine bay and kept the radiators fans running to cool off the engine bay. After about 5 min (I should have done it sooner) I did some temperature readings with my pyrometer and the lower part of the engine bay (headers, exhaust, etc) seemed to be cool, probabllybecause the fans were blowing directly on them. But the upper part the engine bay (intake manifold, fuel rail, etc) was still very hot. The intake manifold was too hot to touch for more then a second and the fuel rail was extremely hot. It was about 160 F if I can remember correctly.
And after driving the car on the street for about 45 min (just crusing around town with the occasional burst on the highway, but mostly calm driving) the car dies on me right when I pulled into my drive way. I was going down my street at about 35mph and when I put the clutch in to brake to pull in my drive way (to make the engine idle) it just died.
Now this sounds "kind of" like a fuel starvation issue to me, but doesn't fuel starvation also happen at high RPM????? I know that the fuel rail and the metal tube that connects to the rubber fuel line from the gas tank to the fuel rail is getting very got. I know fuel boils at a lower temperature then 160 F. Is it posisle for the fuel to be vaporizing when the car is at idle, possibly because the fuel is running at a lower pressure and moving slower trough the hot fuel rail???? What does this sound like to you guys? What coudl be the problem?
Thanks,
