Re: Plenum pull advice
Okay first off It's been a while since I was able to touch my Zr1 project. What happened was I got everything buttoned back up But once I started it I noticed a miss Using my stethoscope i pinpointed which primary injector was stuck Despite tapping I could not get the stuck injector loose. Needless to say I had to pull the Plenum back off again. Once I had the Plenum off I tested all my injectors with a 9 V battery. Only to find that four of the secondaries were stuck. Once they were all free I energized the fuel pump circuit Via The fuel pump pigtail that hangs off the main harness from the ECM. Once the fuel system was energized I then found that I had six secondary And two primary injectors Leaking. So the lesson here is if you ever do a injector Replacement or anything in the valley Make sure to test your injectors before putting the Plenum back on. Now my injectors were rebuilt by a company that a number of people Have used on this forum. Before I go naming names or pointing fingers I want to talk to them on Monday.
