I have a problem with my HJ Monaro. On three occassions over the past week I have taken the car for a drive only to have the car not start again after it has sat for a while (from 25min - 1hr). It is turning over without starting. Then after a few hours it will start again. I replaced the coil and checked all the connections. The high tension lead from the coil has a good strong spark so I am confused what the problem could be. I know nothing about distributors or the ignition system.

Today I inspected the distributor cap and found no cracks and i cleaned a tiny bit of carbon build up from the inside. I thought I would give it another go tonight so I went for a 4-5km drive and parked the car. I turned it off then started it immediately without problems. I waited about 25 min and tried it again only to have the same problem.

Would appreciate any help or opinions.

Thanks Kev

I guess it could be a number of things, I had a HQ v8 doing a similar thing once and it turned out to be a bent shaft on the dizzy, After replacing the dizzy (I went electronic )it never happened again.
maybe a fuel /carby prob also.

I had this once on a Mini (don't laugh. I didn't always have such good taste).

Lots of crank, lots of spark on coil lead, good compression, good fuel delivery. Put it all together, and no go. After many, many days of swearing, cursing and replacing

Thanks Cloudy and Jabba. I will look at all the things you mentioned.

I initially didnt think the fuel would be the problem but it does appear that something certainly needs to cool down for the engine to start again. I will check the fuel lines.

Well this afternoon I started the car without any problems. I plan to look closely at the fuel but I can't understand why I would be getting fuel lock when the weather has been so cool.

Surely the fuel lock would have been happening during summer when

Leaking fuel is never good! But it only takes a few seconds cranking to fill the bowl, even if it drains.

The rotor is a good idea. It's those little things that get the home mechanic...things you learn through years in the business.

Easiest way to check the rotor button is to remove the dissy cap and get someone to crank the engine while holding the coil wire near the rotor button. If it sparks to the rotor button, then replace it.

Fuel leaks from Holleys often come from the accel

Good point. When it has been sitting, not only will the float bowl be empty, but the intake will be full of fuel (mega flooding situation).

The way to start it would be to hold throttle wide open as you crank. Should crank a few times (maybe many), w

Thanks Sandman and Jabba.

Not exactly sure what parts of the carby you refer to but the leak iscoming from underneath the front right corner. There it appears to be a pump because it has a moving part that moves up and down.

Is this the pump you wer
