I am working on the car for mrmarkbrody. Ok here is where the car is. Rich running tend to flood starting. Must pull fuse to ecm to get started again, shutting fuel system down.
O2 sensor is all over the chart from a steady 800 down to 30 on the datamaster software. No leaks anywhere all tested. Injectors when running look like they bounce once in awhile average is 1.5 but for a brief moment it jumps to 30 or so, nutts Is this a voltage problem never seen this before. When started goes into openloop correctly then when it closes loop it tweaks, runs rich eratic idle somtimes wont start back up. Any idea on maybe a bad ecm? Checked prom it is the right chip. Fuel pressure is good I have a adjustable regulator on the vehicle with a gauge. Good ignition/spark all the time. Any ideas would help
