Do you have an idea what it could be or should I get the monitor first? A class action lawsuit was even filed against GM for its use of the CP4, alleging the injection pump was designed around European fuels which have more lubricating properties than the ultra-low sulfur fuel which were accustom to stateside. There is one CP3 I believe that is EGR compliant. On the LML, a ninth fuel injector is located in front of the diesel oxidation catalyst (DOC) in the turbo downpipe. Whats the easiest way to diagnose a cp4 that shit the bed? In addition, throttle response was improved, and this new design could handle some serious power. I would also have to presume that the plug was reinstalled in the correct orientation. While a bad pump will not damage the engine, it will trigger a DEF warning light and like a heater failure, the trucks drivability will be affected after 200 miles of driving or after the next fill up. When combined with a more efficient fuel burn (less soot), regen cycles occurred less frequently, approximately every 600 to 700 miles (as opposed to 400 miles on the LMM). By injecting diesel exhaust fluid (DEF), a mixture consisting of 32.5-percent urea and 67.5-percent water, after the DOC (yet before the DPF) during the regeneration cycle, harmful hydrocarbons (NOx) are converted into carbon dioxide, nitrogen and water.
