[QUOTE="Chipofsc, post: 14945445, member: 166854"] Fuel pressure would run like the RPMs. Low was 30 and high was 70. When he shut the engine down it would not hold pressure and drop to 5 lbs. quickly. I don't know what the program he used but he said it was a ford software. The car data did not show a misfire. The compression data in the program does not tell you what the compression is but that all cylinders were the same. Two cylinders were lower than the others by 2 %. He wanted to do a injector leak down test but the fuel pressure would not hold long enough to complete the test. [/QUOTE]
