Message: [QUOTE="GRN250, post: 1568671, member: 11773"] Working on a '97 powerstroke and it runs good but has started to idle erratically at times. The fuel pressure is within spec and no DTCs are present. The P1276 (Cylinder #6 High to Low Side Fault) occurs when an injector buzz test is performed. The UVCH has been recently replaced along with the two associated injector harnesses. The wiring from the UVCH harness back to the IDM measures .25 ohms on the signal wire and .23 ohms on the ground wire. I checked this against the #8 cylinder and it measured .26 ohms on the signal wire back to the IDM; it shares the common wire with #6 injector. Measuring from the IDM back through the injector measured 3.00 ohms on #6 injector and 3.07 ohms on the #8 injector. This lead me to replace the injector with a Ford refurbished unit. The problem still exists. The IDM has also been swapped with a known working IDM. I am guessing the issue is with the ECM but would appreciate input if others have experienced this problem. Thank you! [/QUOTE]
