2001 Service engine soon 2001 GMC 3500 savana 350 engine Sign In

   I have a 01 GMC Savana with a 350 gas engine . We have had some really cold nights . Van sits outside year round . Van has been sitting for awhile now . Went to start it and no power . I put the charger on and got van running . I tried using my 3.0 Genisys to see what the light was on for . I could only got to retrieve codes and when I did it said I needed to trun key to on . Well van is running so Itried to check data stream and again said van needs to be on . Could van still run and have a fuse blown for the ecm ? What could be wrong ?

That's a definite no. The ECM operates the fuel injectors.

You might want to try a different scan tool.
