Car stalled need advice.
Leaving my mom's house on Saturday the car died on me as I was getting to the end of the block. I gave it gas, it sputtered and died. Tried cranking and it would not turn on but smelled alot like gas. Almost as if it were flooding. I waited for 5 minutes, pushed the gas pedal to the floor and it fired right up. I was able to drive home and took it out for a test drive later on without incident. I have put about 1k miles on the car since i got it and this is the first sign of trouble. Engine is Roush 427r with Holley Carb. New components I installed as soon as i got the car are new ignition switch and new MSD coil. What should i check next?

I probably can't help much but I have a similar setup. I often find that a short stop somewhere makes the car a little harder to restart and also smell a lot of gas.
My particular setup seems to run really rich (came back this way from a checkup down at BDR). Without knowing better I just thought this is how they dial them in. |

Not that this pertains 100% to this post but I found my Roush 427R would boil the fuel in the carb after stops when the engine was hot making it really hard to restart after sitting for 30 min to 1 an hour after a long drive. I installed a 1/4" phenolic spacer ( most I could install so air cleaner would clear hood) between the carb and intake which actually cured the issue.
Just an FYI for Roush 427R owners... |

Do you have a clear fuel filter so you can see your fuel. I wonder if ya got some trash in the line. Just another thought to think about. I've got about 1800 miles on mine and so far no issues other than the fuel boiling problem which I addressed.

I agree with Patrick, I had a similar problem that ended up being a very fine piece of rubber that got between the needle valve and seat on my holley (I assume from the rubber hose when it was installed). Did it a couple of times before a found it because it would work loose from the needle and then do it again!

Do you have an electric fuel pump with a switch on the dash? I was having similar intermittent problems until one day on the way home on the freeway the car stalled like yours. I had a fuel pressure gauge and could see I had no pressure. I checked the fuel pump but it was too noisy to hear, and went to the front and started jiggling the switch and I could see it come on and build pressure and figured out it was the switch had developed a flat spot. (And yes, it was a Lucas switch.)

I agree with Patrick as well (on this one).
I have a small "go bag" that I keep in the trunk with various tools, an electrical tester, an extra rotor cap and a battery powered single-wire timing light from Flaming River....

All good input. Fuel pump is mechanical so that removes the electric pump possibility. However now I am thinking about debris in the fuel filter and or fuel lines. Does anyone know where the fuel filters are on these cars? Are they easy to swap out? Might be cheap insurance if it is easy enough to do on a Saturday morning. Thanks again everyone for the feedback.

I can only speak to my car.
It has in-line filters at both supply and return lines mounted under the car below the driver's seat. Then an additional in-line filter under the hood just before entering the carb. I have a mech pump on the engine that takes the daily work and electric pumps in the trunk that I use to prime things and then only work for reserve or if I lose the mech pump. Hope that helps... |
FWIW, I only have a plain old Carter mechanical pump. If it fails I'm basically SOL but what I would do is just have one of my kids sit on the front of the cowl and spray ether down the carb every three seconds while I limped her slowly home.:cool:

Such a caring dad!
Maybe just get a squeeze bottle and about 6 feet of tubing!;) |

My filter, 2013 build, is located underneath the car right outside the tank on the fuel line going to the front of the car. I keep meaning to install one under the hood so I can see it easier but keep forgetting......this thread may remind me to do it!!!

The fuel filter can vary considerably from a small in-line unit to a large canister unit. I have a mechanical fuel pump and my fuel filter sits on the fender and is quite large. I have sen some sitting right before the carb. You might have to look around a little to see what you have.

Start at the tank and just follow the lines...

...and your Holley may very well have Moraine filters in the fuel inlets (mine does). If you didn't know to look for them, you might not even know about them. They look like little brass meshy things with a spring in them. You need to clean them every so often too. Here's a pic:
