can anyone help me ??? iv got a 2wd saff cossy its a std car part from zorst. it keeps cuting out when and where it feals like it.. its as if its runing out ov fuel. but it will always start back up. or clear.. any ov you out there got any ideas iv just put brand new fuel filter and fuel pump to see if was that but still the same also bypassd the fuel cut off switch. HELP....

 

I may be completly wrong but mine did the same for a while, turned out to be the head gasket. It would cut out then 5-10 mins later start up with a bit of white smoke. May not be the same but never know.

 

something like this happend with mine, i replaced a fair few parts and never got to the bottom of it, in the end b4 it died i just put it down to a loose or dodgy sensor

 

thanks for your help andy but its just had a top end rebuild... and mine starts back up right after it cuts out... but thanks for the nifo and starting to think same as you boost mad. loose wire. but where do you start hav they got fuel pump relay like the the rs turbo ???? thanks for all your help boyz

 

Change the fuel pump and filter

 

Mine was cutting out randomly, turned out to be a dirty crank sensor

 

i was gona say crank sensor maybe, or even temp sensor on back of the head. mine revved randomly sometime aswell lol, but i dont think this was linked.

 

thanks for the help boyz. will giv them a go and get back to you

 

check phase sensor too. it's most likely that or crank sensor

 

agree with phase or crank sensor. Whip the dizzy cap off and look at the phase sensor...chances are the wires are all crusty and fucked. also worth giving the crank sensor a wipe off if its covered in cack.

 

thanks will also try rhe phase sensor to. what dose it do ??????

 

it tells the ecu the phase of the engine. the crank only has 4 pins on it, spaced at 90 degrees. being a 4 stroke engine, the crank shaft makes 2 complete revolutions for every (suck, squeeze, bang, blow) cycle. that means that for example, piston no. 1, comes to the tdc position twice, but it should only spark near that position once out of every 2 times. how does the ecu know which time to spark?

the camshafts and auxilliary shaft (and hence the distributor) have pulleys twice the size of the crank pulley, and only rotate once per 2 revolutions of the crankshaft. the phase sensor basically tells the ecu when cyl 1 is at tdc so that it can time the spark and injection for it. the other 3 cylinders are then done 180 (crankshaft) degrees apart after that.

most clever ecu's like L8 only seem to need the phase sensor signal on starting and you can disconnect it after that and it'll still run fine. one of my cossies is like that. the other on a L6 seems to have cutting out problems caused by a phase sensor fault

 

Does it only cut out when slowing down or @ idle. Or is even when you are accelerate(spell)
