I've been lurking around here a while and have learned alot. Never had a reason to post till now.
I have an r32 gtst with an rb20det, 25t turbo, 550'cc injectors, q45 AFM, and Emanage ultimate to control the fuel and such. The car has been running fine right up until the last week or two. The car started to run way lean (16-19) at idle and would refuse to accept fuel upon acceleration. There was about a 2-3 second delay upon hitting the gas to time the engine recovered. That's just an average sometimes it was worse. We found out the power wire was lose on the AFM, quick fix to put it back together until I had time to resolder. This didn't fix the lean issue as I hoped. I took all the wires off the AFM and resoldered them all but go the ground and signal mixed up and possibly cooked the AFM. The car started ran for about 30 seconds then died and hasn't started since. I have checked most every sensor in the book and tried to line up the timing belt at TDC to verify cam placement, all looks well. I have spark and fuel pressure, injectors are firing. I have tested 3 different CAS all the same result, either all bad or all good not sure. If I take it out and spin the CAS I get injectors firing and until I pulled the power spark (don't miss that on future tests, made quite a bang). All fuses look good, all coils test out the PTU has been used on a different car and there may be something I have missed!!! Please help me out here I have used some really good advice from this forum to help troubleshoot so far, but am out of ideas. Thanks for your time. Oh yeah have swapped ECU's and tried to run without the E-manage still no go.
