hi
i have had just a few problems with a C14SE anyway the ecu flags up error 29 = low fuel pump relay voltage
can anyone give me a clue what to check and how low volts would occur?
i have btw swapped the relay

Fuel pump relay?
Could be a wiring fault, something shorting to earth would cause low voltage to come up
that sounds more like it, i will meter the relay supply see if it earths. to be honest i would have thought a fuse would have blown?Originally Posted by andy_mk3
i have 4 relays 3 second hand and 1 new....what are the chances of all being faulty?
steve
May also be the pump itself at fault.
the pump is a brand new walbro 255 motorsport and filter the fuel pressure is fine at 3.5bar
I guess its not that then!
What problems are you actually having with it?
right here goes
fuel pressure as said is fine
getting a good spark (new coil, amp, rotor arm, dizzy cap and leads)
spark plugs are new and gap is correct
timing spot on and checked with a lamp
new CTS and TPS
car really really tries to start takes about 10 goes before it finally ticks over but it is very 'lumpy' as soon as you hit the throttle the engine dies
from then on it starts first time but dies again
today was the first time the CEL came on and showed code 29, no other codes (apart from 12 )
i have half a tank of fresh petrol
also compression is good on all cylinders
steve
Has a compression test been done?
dam it, could'nt edit fast enough
and before you say it, i have changed the injectors
oh yes and i have a spare ecu
AND A BOX OF MATCHES
