Hi Chupee, I thought I would post your Bring-a-Trailer ad, when you bought it, since it shows detailed pictures of the engine compartment. Bill, John, Jeff, anything here that stands out ?? I know one of our members had a similar problem, 2-years ago, just had the Cobra built in AZ and was driving it back to Washington State, Everything was (Suppose) to be new. The Cobra would run for 45-mins (there abouts) and die, wait 15-mins, it would fire up, and run fine. It turns out (two issues) A semi-coggled in-line fuel filter (Unknown to anyone, under a frame rail, you could find it by following the fuel line). One of those very small glass filters, that can be cleaned, after finding that, the issue was better but still quit after an hour and half driving, that turned out to a coggled fuel pick-up in the tank. I hope some of this will help Chupee, Cheers Tom. https://bringatrailer.com/listing/19...a-and-america/

Twilight zone
So I just walk out to the garage and of course./.
FIRES RIGHT UP AND RUNS PERFECTLY NORM It did not start at 3 pm which was 3 hours after it died. But now it is 750 Pm in LA so it has been 8 hours and it has healed itself from whatever is goin on. So this Spark, FUEl dilemma is not the issue? Open to all interpretations!!!! Merry CHRISTMAS! I will offer a 5 STAR dinner to whoever can solve this! |
Well...
No fuel was getting to it, when the good Samaritan looked at the carb, so start looking at the petrol supply lines. Check for inline filters. Trace it back to the tank and if there is nothing along the way then get into the tank and see what is going on there. Check your fuel pumps for proper action.
Sounds like fuel dribbles into the fuel line over time, and when it gets used up it stops. She won't run without fuel!;) Best of luck with the gremlin! |

Under the external gas cap, is there a secondary cap underneath? If so, it should be a vented cap. If uncertain if you have a vented, or non vented cap, or whether the cap, if found to be a vented unit, is suspect, I purchase an appropriate replacement vented cap and see if that solves the problem. In addition, while picture 115 clearly shows a billet fuel filter, I'd check to see if the filter inside is clogged. Picture 123 shows an electric fuel pump, but no fuel pressure regulator, I'd be replacing the pump and adding a regulator after the pump, and a fuel filter before the pump as well. Finally, picture 114 shows multiple carb spacers, the bottom 1-1.5" may have been required due to the Edelbrock carb currently in place, but the upper "phenolic" spacer needs to be removed and replaced with a simple 1/8" heat shield (just 1) from the MrGasket "3170" kit. I've been using them on all my big block, and small block powered cars for years without an issue. If not used for clearance issues, I'd remove both spacers and just use the 1/8" heat shield in their place. Bill S. |
Pop the gas cap open immediately after it dies, crank it over for a while and if it starts up again, it's the fuel tank failing to vent in air to replace the gas thats pumped out.
Yours has an electric fuel pump, right? Check that it's running. And see if it's hot and failing when hot. And check all the fuel filters. At least if the carb was bone dry when it dies, you've narrowed the problem down to fuel. -Dave |
Pictures show an Edelbrock carburetor. On them there is a fuel filter at the fuel line inlet. Some remove that filter when an inline one like yours is added, others leave it in. I would check to be sure yours has been removed. It is very small and clogs very easy.

Gas cap not vented. Lift the lid and put the pump in. New fuel filter and all lines were replaced a few weeks ago. New fuel pump was installed a few weeks ago, not sure about the pressure regulator. Will ask. The spacer. That was not addressed but will ask..... Also replaced the module and coil 2 rounds ago. (1 month ) Also did this, route a single steel braided or heavy duty rubber rose fuel-rated hose from the back of the carb. straight to the electric fuel pump or hose connection junction going the the pump. Eliminate the Holley fuel regulator. Much appreciated..... QUESTION: I had someone rebuild the alternator and his work was a bit sketchy at times. Could that be the culprit? |

OF COURSE NOT... The fuel is the issue clearly. |

Did you run the fuel line, or did your mechanic? Perhaps fuel line to close to starter, exhaust manifold or exhaust, creating vapor issues and air bubbles that can explain the no fuel in carb issues until everything cools down. You removed the fuel pressure regulator? Need to add a new one just after the fuel pump. Need to add a fuel filter just before the fuel pump under the car. Ok, fuel tank not vented, somewhere on the tank should be a vent of some type, this may be clogged (bugs, ants, bees love to build small nests inside the vent tubes), need to have this checked by your mechanic. Don't over think things, sometimes it is the simplest of items that cause the biggest headaches. Bill S. |
JUst waked out othe garge and i started 1st time and ran fr 5 mn and I tunred it off.
I will send it back for 1 more round of detective work with all these great comments! Stand by & THANKS!! |
Boy, the more I think about this, the more it comes back to a coggled fuel pick-up in the tank. The car's 40yo, probably sat most the time, fuel tank metal breaks down (Scale, rust). Bill what do you think?? My 73 Volvo 1800ES, had to remove the tank (10years ago) because of that problem, couldn't find another gas tank (Most rusted out) the tank guy, boiled out, and glassed (Fiberglass) the inside of the tank, good to go. Mine was so bad, after 10mins of idling it would clog, and died. Or a Vapor lock is a possibility. Chupee, it worth checking. Cheers Tom.

Setup a temporary fuel tank and line to carb. You need to start to narrow down your search. Cheaper than a tow. Engine forward or fuel line back.

I think we (you & I) have owned so many cars over the years, we've seen about everything, that can happen, happen. What's the saying "Seen that, done that, even bought the T-shirt & Hat" I hate when I have to post the same thing, you posted WAY back in Aug. you're always one or step's ahead of me :) Cheers Bill, Tom.

August, yes, but the year I originally posted it was 2003, a little before your time here. :LOL: Bill S. |
Had an awesome conversation with a fellow Aurora owner who has had this EXACT issue several times with SUPERFORANCE and other cars.
He is swearing it is a case of the fuel pump being too close to the exhaust and it simply overheats and dies, I need to see how close it is but its getting down to the nitty-gritty!!!! I think.... thanks for all the thoughtful info..some pretty wild ones also!!!! |

Lose the spade terminals. Google how to tie wire, crimp on a barrel and add two layers heat shrink tube. Check by blowing thru or just change filter. Check filter on carb hookup too. With filter removed from pump run some gas and see what comes out of tank. That’s a small pump. Looks cheap. If it’s old just change it to a better new pump. |
