Truck Repair Service 101: How Wo Fix A Hard-Starting Truck

Truck starting problem?

Truck batteries endure four to five years under regular usage. Get your battery examined if your truck is cranking slower than usual, your “check engine” light is still on, or your headlights are dim.

In this scenario, truck hard-starting isn’t exclusive to the winter. Regardless of temperature, there are typical causes of long cranking durations. In this article, we will dig deep into how to fix hard-starting trucks in detail.

What are the most common hard-starting symptoms in trucks?

Don’t give up if you’ve tried everything to start your vehicle but are still sitting helplessly on the side of the roadway. Hard starting is usually the simplest to diagnose of all the truck repair concerns.

Even though it’s irritating when your truck won’t start, it’s essential to recognize the signs that indicate hard-starting trouble so you may take the appropriate measures to fix it.

  • A dead or weak battery
  • Starter Contacts are no longer working.
  • Starter assembly or circuit issue
  • Neither a battery problem nor a starter issue

1- A dead or weak battery

Common symptoms of a dead or weak battery include:

  • The feeble cranking begins when the key is turned in the ignition.
  • Very low or nonexistent dash lights
  • There is either nothing electrical that works or barely does (e.g., the window scrolls down a lot slower than average).
  • The dome’s internal light gradually fades out.
  • Internal and dashboard lighting flickers.
  • All electronic components are fully functional.

How to fix it

  • First, inspect the terminals for looseness and rusting.
  • If a battery’s lifetime has expired, it should be replaced rather than recharged or conducting diagnostics.
  • If the connection is good, upgrade the battery and recharge.
  • Drive the truck for 20–30 minutes to see whether the battery will recharge, yet do not pull over to determine if it will restart.
  • If recharging doesn’t work, you’ll have to replace it.

2- Starter contacts are no longer working

Common symptoms of a starter problem include:

  • Put the key in the ignition, and the engine will start to crank.
  • The dashboard lights get a little darker for a second, but then they stay vivid.
  • The operation of all electrical accessories is regular.

How to fix it

  • Take the starting solenoid apart and replace the contacts.
  • If comparable price, replace starting solenoid assembly.

3-Starter assembly or circuit issue

Common symptoms of a starter circuit issue include:

  • Cranking happens when the key is turned in the ignition or when the starter button is pressed.
  • The lights on the dashboard remain operational.
  • Every electrical accessory is operating correctly.

How to fix it

  • Depending on the problem, you might need to replace the starting contacts, solenoid, or whole starter assembly.

4- Neither a battery nor a starter issue

Cranking occurs after putting the key into the ignition. It is operating fine, but it won’t start. The truck can’t move until it has air, gasoline, and a spark.
