righto then ive not long bought a 1.4 16v sri on an m reg to build into a road rally car it goes really well but 2 things are buggin me so answers on a post card please !
firstly it keeps blowing fuse no 1 for the hazards ,horn etc any ideas ? secondly like i said it goes really well but after driving it today the em light came on and stayed on no loss in perfomance at all still hits the limiter fine ! i know the muppet who owned it before cut the wires from the rad fan switch but thats wired to a switch on the dash could this put the light on and could that also stop the temp guage working as im not sure if it does !

thanks for looking
simon aka jarjar

another jarjar lol..from the pic in your avator looks like a pretty damn nice car...can u put sum pics up on project log or sumfin? cud do with seeing more rally corsas..need ideas for mine and i just love seeing em.

YEA the radiator fan will be causing the engine light to come on
as it tryed to turn the fan on and cant, because its on a manual switch so assumes its broken and puts the warnign light on
im guessing he has faulty thermostat so it wasnt turning the fan on so he bypassed it to a manual switch
wont affect your car too much really just annoying with the light comming on

not sure on the hazards m8, you sure you had the correct ampage fuse in it? ether that or you have a short someware or some bare wires touching.

cheers for that it gives me somethin to try at least

good luck let us know how it goes

just used a pals trouble code reader and it comes up with 4 codes one is to say the reader is workin two of them dont tally with the code book and the third says quad driver module ? anyone have any ideas ?

What are the codes you got mate? ill have a look and see what i can come up with....

cheers bud the codes are 12(shows system is working) 85 ? 92 ? and 93 quad driver module qdm the codes are for the gunsons type tester so i dont know what the equivelent tech 1 codes are and the local main dealer i used to work at dont have a tech 1 now !!!! for some reason tho 1620 rings a bell for the tech 1 code ? might just be me tho need to get it done tho the car is driving me mad it came from essex as is via a pal who did nowt to it and every thing has been messed with and done wrong its that bad im havin to sort all the poo before i can do any rally prep work on it. if there are any voleteers who know one end of a spanner from another who fancy comin and helping me i make a mean cuppa
cheers simon

Right as you said 12 is start and ending of diagnostic.

85 Imobilizer control module incorrect signal
92 Camshaft position sensor incorrect signal
93 ECM circuit malfunction

quad driver modual is just somthing that controls 4 seprate circuts
most likely its because of of the cooling fan problem looking about forums most people say they experience this if having problems with themostat or radiator fan faults so id say it was that

cheers fellas gives me something to go on hopefully i should get something sorted this weekend ill keep you posted

and ur temp gauge might not work as its just a silly little spade conector sumwere near the thermosat and its not protected so can fall off from time to time or get a bit rust worth lookin for it bud

well ive not done anything to it but the light has not come on for a couple of days now not that i think its cured ! i think is acyually the cam sensor causing the problems did some testing at the weekend and managed to replicate the fault ( i think ) so i need to get a new cam sensor to start with then go from there !

my EM light came on all the time wen the car wheels spun or jurked and it was a plug that sits in front of the battery wen it gets a nok it disconects couseing the EM light to come on a bit of black nasty sorted that. mines is the 1.6 16v ecoshed so not sure if the 1.4 16v eco is the same but am sure it is so try that as well
