The fuel rail pressure was 500 bar and no matter what I did I could not get it down. Couldn’t do pump learn as pressure too high.
Some how I had ordered 2 SCV,s so out of desperation I put the second new one in. Bingo worked like a charm managed pump learn. Test drove it and it drove better than ever. Happy days. Stopped started all day long.
Went out this morning van wouldn’t start just got it going and fuel pressure is back up to 5/600 bar. It does not make sense to me. Tested pressure sensor 12v on live good ground on other and 2v on sender wire.
Tested wire on SCV got a good 12v on orange wire. Didn’t test other wire as not sure what I should be measuring.
It’s as though the SCV is staying open hence the high fuel pressure. But why after leaving it overnight this has now happened on 2 occasions. Very confusing.
Are they "genuine" Ford or Denso items..?? If they're cheap ebay or similar items, they just cause grief, fail to work properly etc...
