2001 lb7 duramax. New long block, new Bosch injectors, fuel pressure regulator, fuel injector control module, ecm, tires,batteries, brakes, maf sensor, front windshield, marathon seat covers,all fluids changed in front and rear differential, transfer case and transmission. Truck has a long start issue when it’s warm. First start it fires right up. I put a set of injectors in it with the new long block. Had the long start issue. Mechanic said it was injectors. Replaced them with new Bosch injectors. Not remans. Issue still persist. Engine comes with 100k transferable warranty. I have receipts for all purchases. Truck will come with old injectors if someone wants them since core is not required when purchasing new injectors. I have around 30k in the truck. If someone could fix the long start issue it would be a solid vehicle.
