Re: GN Sigma - Intermittently Wont Start

Sounds like your ignition coil is on the way out....also remove coil lead from coil and check that the coil tower is not burnt/black. Check condition of spark plugs-take all 4 spark plugs out,if one or more are shiny and clean this indicates that coolant is entering into combustion chamber.Also chec...

Re: GN Sigma Temperature and Fuel Gauge not working

Yes you need to take out the guages and clean/or replace the voltage regulator which is mounted on the rear of the guage cluster.Very easy to clean,if still no good an auto electrician/instrument specialist should be able top source a new voltage reulator.

Re: Auto choke woes

Just a correction to the above post.Peter Wherett Sigma did not not come from factory with Weber carburettor.They used the same mikuni /solex carburettor as other Sigmas,but had factory fitted extractors.This was just pointed out to me by my friend who owned one of these cars back in the 1980s.

Re: Using Goss fuel pump G575A over G642A? GE Sigma 4g52

Pump will work fine with return line blanked off..blanking plug should come with fuel pump,just make sure you use the correct fuel resistant plug.According to Goss website,G642a supersedes G575a,so pump should work as long as actuator arm is the same...just compare it to your old pump to make sure.
