The Chevrolet Silverado 1500 entered the market in 1999 to replace the C/K lineup while product designers executed several redesigns to boost its specifications and operating capabilities. At launch in 1999 Chevrolet Silverado 1500 offered three powertrain packages including 200-horsepower 4.3L V6 (Vortec 4300) alongside 275-horsepower 4.8L (Vortec 4800) and 285-horsepower 5.3L (Vortec 5300) engines that came with 325 lb-ft torque. This product launch from Chevrolet in 2007 introduced the GMT900 platform with a 4.3L V6 engine that provided 195 horsepower and 260 lb-ft of torque and operated through four-speed automatic transmission. Between 2013 through 2018 the third generation Chevrolet Silverado 1500 lineup received EcoTec3 engines that brought together these three power options: 4.3L V6 and 5.3L V8 and 6.2L V8 that provided better efficiency resulting in enhanced performance. The third generation Chevrolet Silverado 1500 achieved better handling through its combination of aluminum parts and high-strength steel frames which also brought weight reduction benefits. The transmission technology in Chevrolet Silverado 1500 included an advanced automated six-speed system for logic-based transmissions that enhanced speed and fuel efficiency during gear shifts. Factory-standard parts used in the Chevrolet Silverado 1500 have preserved its excellent manufacturing quality from the start and ensure performance and durable operation for users.
Chevrolet Silverado 1500 issues group into drivetrain control, engine fueling, and fuel level measurement. In drivetrain control, the Silverado 1500 may display a service message and lose mode changes. A failed transfer case position sensor or selector switch confuses the controller. Scan the module, replace the transfer case position sensor, and verify engagement on the Silverado 1500. In engine fueling, the Silverado 1500 can misfire with a warning light. Stuck fuel injector tips starve one bank and cause rough running. Perform cleaning procedures, then replace the fuel injector if flow does not return. In fuel level measurement, the Silverado 1500 may show an erratic gauge. A worn fuel level sensor inside the module causes false readings on the Silverado 1500. Replace the fuel pump module on high mileage trucks and inspect connectors. Follow Chevrolet electrical tests to confirm power and grounds. Apply Chevrolet torque specs and sealing checks during reassembly. Complete a road test and relearn drive cycles using Chevrolet procedures. Record pressures and trims so the Silverado 1500 remains predictable. Verify no leaks and confirm stable temperatures after service on the truck. These steps organize faults by system and restore dependable operation.

Then, take off the Ignition Coil wire from the coil and from the Distributor Cap, then the Spark Plug Wires by twisting each boot 1/2 turn and pull the wire boot. Screw out the Distributor Cap and take it off. Mark the position of the rotor in relation to the housing of the Distributor as well as Intake Manifold and pull out the Distributor hold down bolt then distrubutor thus observing that the rotor will move clock wise 42 degrees. When installing, use a second mark on the base of the Distributor for alignment. If a new Distributor needs to be installed, there must be two marks on the housing and they must be placed in the same location as the old one; rotor must be aligned with the second mark and the Distributor is to be installed in such a way that the rotor turns clockwise about 42 degrees. The rotor division should end on the mark on the Distributor base ; if it doesn't, the Distributor should be removed and replaced. Torque the Distributor hold down bolt to 25 n.m (18 lb ft), install the cap to the Distributor with new screws torqued to 2.4 n.m (21 lb in) and re-attach the cmp sensor and fuel pump/oil pressure sensor. Reattach the Ignition Coil wire by placing the coil wire nipple in an angle of 35 to 60 degrees aft of perpendicular from the engine centerline. If the malfunction indicator lamp (MIL) is on and dtc p1345, dist. Will be installed improperly. For the second installation, rotate the number 1 cylinder to top dead center (TDC) of the compression stroke, matching the crankshaft balancer marks with the engine front cover tabs. Line up the white paint mark on the Distributor stem with the pre-drilled indent hole in the gear to align the rotor segment with a v6 engine .
