there is alway something wrong but this has me beat.
car just started to hold back while driving and then cut out it started again but it would just tickover and not rev. towed it home and same again would start but as soon as you touch the throtle it dies changed the plugs and fuel filter as i had some lying around.
put a gauge in the fuel line and it says 0.4 bar (5 psi ish)not sure how accurate the gauge is but does this sound ok.
help someone please

fuel pressure should be closer to 3 bar with the vac connected to the regulator 3.5 with the vac off so no 0.4 bar is a serious issue, pump mabe

 

cheers trevcoss hope thats the case

 

saw a cossie recenlty with a one way valve for the breather on the vac line to the fuel press reg, was giving similar probs.

 

Your either out of fuel or out of fuelpump(milage )

 

i hope yous are right and its just the pump cheers everyone

Could be a regulator gone duff( you're gauge might be innacurate), so might as well try seeing if you can up the pressure by adjusting it.
I would first though CLAMP the return line, this will ensure you get all the pump pressure, see if it revs ok, don't keep clamp on, otherwise it will be VERY DANGEROUS.
WHEN WAS THE FILTER LAST CHANGED ?
As said pressure with vac on is 3 bar vac off around 3.5 but up to 3.7/3.8 depending on how good your engine is!!
A rewire of the fuel pump is also a good idea, whether it is the pump or not.

possible fuel relay ,does it prime on start ??

 

thanx for the help peeps havnt been back on as ive been trying to polish my old turd.
thanx tabs fuel gauge must have been donald ducked as i put on a group a pump and it didnt show much more and it had the pump rewired last year.
cheers stage 3 muppet is the pump relay in the dash next to the ecu as i cant hear it prime before i turn the key the last stage to start it.
cherrs everyone maca

 

mabe the regulator is knackered?

 

poss regulator can u adjust the pressure or does it stay the same

 

woo hoo its sorted thanx everybody for their input but in the end it was the 3 bar map sensor but what the hell its back on the road.
cheers maca
