2001 Suburban Died, Won't Start
I have a 01 Suburban 1500 with a serious problem. About a week and a half ago it died while idling in park. Took a few seconds but it did start again and drove with no problems. Then a few days ago it died just as I was pulling into my driveway and wouldn't start at all. I hooked up my scan tool and it showed P0706 (Transmission Range Sensor Circuit Range/Performance). I tried clearing to see if maybe it was just a bad sensor or something and it fired right up. It ran normally until yesterday when it died idling again and wouldn't start. Hooked up the tool and this time it showed U1041 (Loss of EBCM Communication) and P0335 (Magnetic Crankshaft Position Sensor Electrical Error). Tried clearning it again but it still won't start and it won't show any DTCs now. The engine will turn over when starting, but just won't actually start. With it being the same problem but different codes, I'm thinking this could the be the ECU. What do you guys think?
Thanks a lot for your advice!
HAPPY NEW YEAR!Andrew

Hopefully that will do it. Good luck to you. Where did you find an ECM from?

Haven't tried. I'm fairly confident that this is an electronic, not mechanical problem. It's worth a shot I guess. Never used that stuff before, where do I spray it and do I do it while cranking it or before cranking?

Didn't really think that the fuel system was the problem.
Funny thing...I tried starting it today for grins and giggles and it started right up no problem. Problem now is that yesterday it had died inside one of the indoor car wash stalls on base and today they disabled all the roll up doors since it's -23 and they don't want anyone using them when it's below -10...and now they're off work until Tuesday :( LoL So hopefully it'll still start on Tuesday and I can at least get it home.
Now, I am convinced this is an electronic problem, not mechanical. Anyone know if this would be the ECM or could it be some other system/circuit?

Roger that. I'll try that if it doesn't cost too much. Please post an update when you get your ECM!
