Expert Repair for All Major Light-Duty Diesel Platforms

What to Watch for in Your Diesel Truck

Diesel engines have unique warning signs that shouldn’t be ignored. Spotting them early can save you from expensive breakdowns and keep your truck on the road where it belongs. Here are the most common issues we see at Tanzillo Automotive.

Hard Starting or No Start

If your diesel takes too long to crank, smokes while cranking or won’t start at all, it could be a failing glow plug, low fuel pressure, or an electrical fault. These issues can quickly leave you stranded, so we get to the root of the problem fast.

Loss of Power or Rough Running

When your truck feels sluggish, struggles under load, or just doesn’t pull like it should, it could be related to injectors, boost pressure, or airflow sensors. We isolate the issue and bring your performance back up to par.

Excessive Smoke

If you’re seeing black, white, or blue smoke from the exhaust, your engine is trying to tell you something. Black smoke usually means too much fuel, while white or blue smoke could point to coolant or oil entering the combustion chamber.

Fuel System Problems

Water contamination, dirty filters, or worn injectors can lead to misfires, hesitation, or even long-term damage. We thoroughly inspect and service your entire fuel system to keep your truck running clean.

Turbocharger Issues

A drop in power, slow throttle response, or odd whining noises may point to turbo failure or a leak in the boost system. We diagnose and repair turbo issues to restore power and prevent further engine stress.

Warning Lights & Codes

When the check engine or glow plug light comes on, it’s time for a deeper look. We use advanced diagnostics to pull trouble codes, monitor live data, and pinpoint the exact cause so there’s no guessing.
