Hi Guys And Girls. We have put the dash all back in our coupe after replacing a plug and just a general tidy up. What we are getting is when we turn it over it starts but it wont idle unless i hold they key between on and start if i let it spring back to its normal position it just dies. Any ideas ? Coil, Ignition ????

check the ignition switch is doing what its meant to with a multimeter, id also be checking that the wires that go onto the ignition switch are in the right spot.
did you replace the plug with all the ignition wires in it? maybe you got some round the wrong way.

Hey Dude. Nah didnt replace that plug just a main one to the Engine bay harness i have tripe checked it only 4 wires so its all good. At first it wouldnt start just reds on the dash. Then i found some wiring to a kill switch that i had put to one side of the gearbox tunnel flicked it and bang it started but then the above problem.

its ethier the coil resistor or the wiring to the coil resistor. come on have a go u should of been able to work that out . When u turn the key to start it bypass's this resistor to get maximum voltage to the coil under cranking, but during normal running postion it use's this resistor to maintain no more than 12v to the coil as it would overheat them running at 14v for too long.

That all sounds great Number 1 im not a sparky and 2 i didnt remove any wiring in the engine bay just tidied it up with electrical tape and soldered some wires and covered them with Heat shrink. We removed a resistor type thing but that was for a diverted starter switch as the ignition doesnt always kick it over. Thanks Andrew

what carby is on it? it may have no power to the idle swich on the carby

Nah old school A12 carby none of that fancy stuff on it. Thanks for your reply.

Update. Now car wont start at all. HELP, Electronic dizzy and electronic igniton suited bosch coil, Lost for answers

BUMP

not sure bud id look at earthin that sometimes can be a prob, also when u did som fixin did u use a flux soilder or dry solider as maybe you have over heated or have a dry soilder joint!!
also that switch on the box was the coupe a auto at all in its life?? co the autos have a setup 4 p and n that need bypassin, via that switch id say, it may b shortin
does it have auto choke??
