Got a slight problem, my S2 keeps cutting out when i drive along! have tested the fuel pump and the battery is holding charge. i just drive along and it cuts out and will sometimes start and sometimes not!

anyone got any ideas

 

Would it be an air leak ?

 

Possibly an electrical problem.

When it cuts out and will not start can you hear the fuel pump?

 

i can drive for a mile or so and then cut out, this morning i drove it 10 miles and then it cut out, it almost seems as something is loose and shorting out? i have no idea!

 

yeah the pump seems ok

 

Proably a poor conection somewhere.

With the engine running try moving the loom around and wiggling the wiring to sensors etc to try and locate the fault.

Could also be the hall sensor in the dizzy breaking down.

 

cheers for the replys, i have changed the dizzy and rotor arm, but im thinking it has to be a dodgy connection some where!

 

When u say it cuts out - how? At what rpm? What load? WHat happens exactly? What does the rev counter do? Does it splutter? Is it a dead cut?

 

fuel pump relay have you taken it out to see if its burnt out?

 

I have changed the fuel pump relay, as for the cut out. it splutters and then cluts out its can be through any rev range.

once it has cut out it will sometimes start and sometimes it will. its very stange

 

So you could be on boost, and suddenly it will splutter?

 

i dont have to be on boost i can be driving off boost and it will happen!

 

3 wires in the dizzy must be a break in wires to the fuel pump?

Yes, but does it do it ON boost? And is a dead/clean cut - or splutter?

 

Change the coil.Regards,Micky

 

as Mikey says, change your coil, had this on mine

 

check and replace your battery earth wires if necessary
remove and clean/tighten where they fasten to the body/gearbox

bad earths are the most common electrical problems you can have , especially with the amounts of rust your cars have your side , i want to cry when i see it on your project cars......

 

Dizzy would be my favourite, i dont think theres an RS left that hasn't suffered with the sensor breakinf down (mine is on its way out).


Next time it happens watch the rev counter.........

And if it wont restart listen for the fuel pump when trying to restart, you'll probably find it will only prime and doesnt run when you crank the engine.

 

Had exactly the same problem on mine when i used to be sat in traffic it would just cut out , the loom by the fuse box that runs along the bulk head used to get hot and there was obviously a broken wire in there. wiggled it about and would start again. ended up havin to change the wiring loom got one for £40 with a clifford concept 500 on it!!!!!
