Rear driver side of fuel rail should have a threaded boss for the short (2-3") ground strap that bolts next to plenum bolt in same area. Bernie is very emphatic on having this ground connected, so I think it's a good idea. I agree with Cjw3 on overall problem being chip and or ECU issue. Especially with no blinking light. Gary aka: DVDBURN does a great job at repairing ECU's.
