Have they got the winter plug thingy disconected. The green plug on the side of the top of the engine. Can't remeber what it is called but tells the ecu what the temp of the engine is and then does the choke accordingly, but if this is not pluged in then it will over fuel and not run on tick over , but will run with a bit of throttleQuote:

It does idle OK at the 12+ degrees of ignition advance, but only for a short while. Then it surges a little and dies. During the surging it won't react to the throttle (ie, it won't rev up and it will die, nothing can be done to prevent it).
Hmmm I have a Rangie I'm running a GT40r with a CraneCams Fireball electronic ignition, I've been running it like that for about a year-ish and it runs very well.Quote:

The GT40R is designed to be used with a ballast resistor.Quote:

The idea of this being is that when the motor is being cranked over with a full 12 volt system, the battery voltage drops & weakens the spark from the ignition coil, making it harder to start at times.
With the 9 volt coil & ballast resistor system, the resistor is bypassed when cranking giving the coil extra voltage so producing a bigger spark which makes starting easier.
If you fit a GT40R to a non-ballast resistor system, the coil will be receiving this extra voltage all the time & while it will work great, it won't last.
Most electronic ignition systems don't use the ballast resistor so you might find you have the wrong coil fitted to your car.
So that means my choice is to change to a coil that is designed NOT to work with a ballast resistor OR fit a ballast resistor?Quote:

Is it better to fit a different coil or fit a resistor or does it matter either way??
Most older Rangies have a resisitor wire running from the ignition switch to the coil.
If you have two wires to the coil, one comes from the starter solonoid and is 12 volts for starting, and the other should be a white covered stainless steel looking wire with bands every now and then ( it may have resistor wire written on it). This one drops the volts to 7-8 for normal running. AFAIK no rangies have a ballast resistor but they do have the resisitor wire.
Do not cut and shorten this wire (significantly) as the resistance is dependent on its length.

Nope no wire on mine, someone probably removed it at sometime.Quote:

Simple terms are that the gt40r coil or the gt40 are both preaty well a crap coil they are just your avarage coil with a flash sticker ...
My rangie is runin a crane 3000 series unit which dosent require a resistor coil and im using a MSD blaster coil which is designed to run at 12v and it gives off a spark that could kill a man as it got me once and it was worse than a 240v shock it made me sick in the gut and i had to sit down for a while to get over it ..Quote:

Cheers guys

Anyhow, I have the Fireball XR700 so it looks like I'll be getting a ballast resistor before I drive it again.
I'm guessing that I fit the resistor on the + side of the coil between the ingnition unit and the coil?
