When I start the engine cold I always get the stop engine warning light and buzzer. I check my VMSPC says that I have either "High Voltage" or sometimes "Low Voltage" injector 4.
After the engine warms up or I am over 1100 rpms the warning shuts off.
Anyone have any "self service" ideas. I am pretty good mechanical, I know my way around, so if not to intense - I should be able to change or check anything.
Thanks,

Low batteries (slow cranking speed ) will trigger the engine shut down light. I had that problem and found two of the three optima batteries were bad (18 months old!) Try starting with the boost switch on, if that helps check those starting batteries.
I have checked the codes in my VMSPC hook up and it states that I have "low voltage", sometimes "high voltage" at "injector #4".......
Just wondering if any Dzl mechanics out there can tell me what to do?
