xe problems

[jaywalker]

hi peeps, I'm having a problem with my dizzy nova xe, when I start it up and drive for about 5 mins then turn it off and try to restart it nearly flattens the battery but will eventually start, this happens everytime I drive it, any ideas, could it be a coil problem or dizzy or maybe something else? nothing seems loose and when I drive it really hard it starts missing n backfiring, any help appreciated thanks

Check the ignition timing with a light to see if thats out. When was the last time you changed plugs, leads, dizzy cap and rota? You could always take off a fuel line and turn it over and see if it could be lack of fuel pressure aswell

if you run it for more than 5 mins is it ok?

i'd guess its the coil/amp

how old are the plugs & HT leads?

just as a random suggestion, is the cooling system airlocked? cos an overheating head will cause similar problems

[jaywalker]

mmm I have changed the radiator recently and the dizzy n cap but not the amp & coil, can I use any other coil n amp as I have a few off other vauxhalls (nova n astras!) just wondered if I specifically have to use an xe one.? haven't changed the ht leads for ages but I will, as I have another set, how do I know if it's overheating? cheers for the advice so far ;-)

if I literally start it up and drive 1/4 mile then turn off it won't start instantly., really struggles

sounds like a sensor fault. maybe ECT. stsrt with the basics as Mowgli suggests, then pull the fault codes or read live values.

[jaywalker]

ok thanks, how do you get fault codes?

start no problem when cold?
temp sender could be at fault. next time it does it unplug it and see if it starts , my let did the miss fire thing under hard driving and it was down to the temp sender

[jaywalker]

starts first time when cold yes! so maybe if I get one this may rectify it, thanks everyone ill try it all lol
