Hi just wondering if any one has come across a problem iv got, iv got fuel up to the high pressure pump but theres only a bit coming out of the outlet but not much pressure the customer has bought a second hand pump which has been tested but still the same problem. Just wondering we're to start with the scope? Iv got a 12v feed to the two pin plug on the pump could the fuel rail pressure sensor cause this problem?
Iv got 2 bar from the lp pump,iv got 0.65 then when cranking goes up to 300/400 on the frp. But what doesn't seem right is when I crack the pipe off there doesn't seem to be any thing there very little diesel.
Iv got a 2 channel ADC 212 which iv only just started using new to this just trying to learn as much as possible,info would be really helpful. I'm a novice who is trying to learn the hard way lol
On the injection quantity mg/stoke all 4 are 0.00
Also wont attempt on easy start which I would of thought valve timing was out but iv checked that and done compression test. But should still have fuel out of pump
The HP pump delivers pressure not so much volume & you should not be cracking the pipe off to see !
What does your info system tell you about the LP ??
take 1 CH with cranking current & the other on the FRP signal, but it's no good telling you to post the capture as you never do which makes it difficult to try help.
What readings did a compression test reveal for each cylinder ?
& no attempt to start on sniff ??? is this the 150 ??
Milage ?
Do you have the 600 & low amps clamps ?
