{"product_id":"4-3l-engine-control-module-ecm","title":"4.3L Engine Control Module (ECM)","description":"The GM 16265045 is a remanufactured Engine Control Module (ECM), also known as a Powertrain Control Module (PCM) or Engine Control Unit (ECU), designed as an exact fit for the 1998 Chevrolet Blazer with a 4.3L engine. This unit is VIN programmed and flashed with the latest software updates to enhance drivability and fuel economy, ensuring a \"Plug \u0026amp; Play\" experience that bypasses costly dealer programming and key relearn procedures when the optional GM Clear Security is selected.\n\nACR, a reputable remanufacturer, produces these modules in the USA, backed by a Limited Lifetime Warranty. The module is tested for functionality prior to shipment. Installation involves disconnecting the battery, replacing the module, reconnecting the battery, and following a simple key relearn procedure, unless the GM Clear Security option is utilized, which makes the unit completely hassle-free.\n\nCommon issues that may indicate a faulty ECM include check engine lights, false engine codes, engine stalling or misfiring, poor performance, starting problems, no injector pulse, and issues with the charging system or fuel economy. This module is specifically listed for the 1998 Chevrolet Blazer 4.3L, with a generic hardware number of 16263494. It also fits other Chevrolet models such as the 1500\/2500 Truck, C\/K Series, S10, and Express vans from various years, often with 5.7L or 5.0L engines, indicating broad compatibility within the GM platform.","brand":"Chevrolet","offers":[{"title":"Default Title","offer_id":52688567566648,"sku":"16265045","price":170.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664202483.jpg?v=1784891123","url":"https:\/\/store.motormia.co\/products\/4-3l-engine-control-module-ecm","provider":"MOTORMIA","version":"1.0","type":"link"}
