I have a 2002 gmc duramax, it'll try and fire up, but just won't. Replaced everything on the motor. I heard it could be the TCM, but don't want to spend the money and it not be that. The Injectors are aftermarket and are just fine. Had them checked, everything on the engine has been checked. Need help please

LB7 2004 Has hardly no heat
When driving down the road, plenty of time for truck to warm, it is putting out luke warm heat, control set on 90...no leaks, fluid is full,had radiator replaced about 4 months ago, havent tried flushing heater core yet but will try if you guys think it will help, also thought maybe the thermostats, just seeing what you guys think maybe a cause, new to the site and thanks in advance for any help, temp here in Georgia high 20's to mid 30's if that helps any on the heating end of it.

my heat wasnt working right and I got tired of it. It was 20 degrees where I live in TN and decided it was the Tstats. Drained some coolant, took old out and replaced and works great now. Takes me long enough to get from home to work (which is about 5 minutes) for it to heat up.

Thanks

So both therms and it works perfect, is that what ur saying? Mine fluctuates with engine revs, on the hey and give it throttle and it warms up, stopped or at a light, goes back to Luke warm or hardly anything. I guess it wouldn't hurt to just change them anyways, did you use aftermarket or genuine, I'm not to good for aftermarket so I might just give it a run, what temps did u get?
