I have a few cars that have sat for a while and now crank but won't start. 94 E420, 94 C280, 89 300SEL for example. They do run a second or two with starting fluid so I suspect fuel pump inop. Would this tool be compatible with the fuel injection systems in these cars? Both as a diagnostic aid and just to get them running so I can move them around.
