Think my 044 primes for about the same time too?

My prime on the L6 ecu was about 4 seconds from memory, defo nowhere near 20-30, but it's ecu controlled, wouldn't worry so long s it's working as it is purely just a timed pulse from ecu.

cool,its an L8 ecu,just heard it this morning reckoned it didnt used to take that long,but never paid much attention before,lol
thanks for replies puts my mind at rest,bloody cossie paranoia!!lol

tabetha

Plenty of cossie paranoia, I was like it to start with, just resigned myself now to if it goes wrong it goes wrong, but it only had a hiccup or two in 3 years, even managed to do 20 miles home after HG blew, stopping every 5 miles and refilling with water.

there mite be air getting in the system check the connections on the fuel filter check the rubbers haven't crumpled up or bin pinched and then if that dnt work check the fuels pump connections (wires) c if u got a good connection

tabetha

If air was getting in, or even if the outlet pipe was disconnected it would not alter the prime, the ecu does not know what pressure is in the fuel rail, it purely gives out a timed supply when it wants.
