So I've been having some issues with spark! So far, I've put in a new battery and swapped in a new rotor arm, distributor cap, HT leads and plugs but still zero spark on turn over. I've also checked the resistance of the coil which sits at 3 Ohms so I think that's good, but correct me if I'm wrong please. What else could be causing the issue?

Cheers

Hi Donald

Is your car on traditional points and if so have you checked the gap?

Then disconnect the coil from the points and hook up a 12v bulb one end to the battery, the other to the wire to the points, when you turn the engine over by hand does the bulb light and go out as it turns? If you get permanent bulb on or not at all then you have an issue with earth or capacitor. If you get turn on/off then...

Next reconnect the coil and arrange for the lead from the coil to go to a spark plug if you can fit one onto the end and see if you get a spark whilst turning over the engine on the starter. If no spark then either coil or lead.

Assuming a spark then the issue is with the disti cap and or cables.

Check you are getting 12V to the coil ignition on as well.

In the process of resetting the gap on the contact breaker, I noticed a tiny bit of corrosion on the points. Low and behold, after a quick clean = spark at last!

By squirting some fuel into the carb, I've managed to get the car to fire for the first time! What a joy that was...
However, the engine is running rough and it seems like the fuel getting to the carb is inadequate. Therefore, I've been thinking about a new fuel pump and I've reached the crossroads between mechanical and electric.

Does anyone know how I'll be able to find the Gallons Per Hour rating of my Beta in order to select the correct pump if I choose to follow up with the electric pump? Currently looking at Holley's range.

Also looking at replacing the rubber lines. Any recommendations would be greatly appreciated. I believe its 8mm and 4mm bores.

Thanks for all of the advice so far!

Hi Donald
For your car i'd recommend the electric Huco 'pull' pump from Fast Road Cars.

It's around 65.00. Beware of cheap copies, ask me, I know!

It's designed to fit in the engine bay, pulling fuel. Lots of info on this forum
on how to install. You can leave the existing pump in place, or remove and fit a cover plate.

I'd also suggest an inertia switch as a safety precaution. Any will do the job.

On hoses, get the Gates branded items, and make sure they are suitable for
ethanol-based fuels.

Hope this helps
Nigel.

Hi Donald

You need R9 rated fuel hose and get branded, not Ebay etc as stories of relabelled R6 etc.

As to sizes I seem to remember 8mm and around 5mm, but easy enough too measure.

See this for discussion on petrol pipes
