Fuel pressure has always been on my mind but the only way of testing I had was to measure flow!
It has always flowed 3 litres in 60 secs and as a minimum its supposed to do 2.5 litres in 60 seconds! However as I always tell everyone flow and pressure are two seperate things!
MFI fuel pressure guages are very hard to come by! You can go pick up a EFI one for £20 in the local factors but you cant use these on MFI, they wont connect never mind read 6 bar!
So not a tw*t mate...
It seems to have been intermittant but was happening all the time when I got the guage was the car was priming and going up to 6 bar before coming straight back down to 2 bar! Then you'd start the car and it would go up to 6 bar before coming back down to 2 bar! The pump was priming again - not running constantly! So ive rewired it now and done away with both the pink and brown relays, more trouble than they are worth! Last thing I want is to be at a trackday and the relay goes, days over and push it back on the trailer!
