2015 Silverado Cranks a Lot Before Starting - Anyone Else Having This Issue?

I’ve been experiencing quite a frustrating issue with my 2015 Chevrolet Silverado lately. The engine seems to crank a lot before actually starting, and it’s not getting any better. I’m hoping to get some insights from fellow owners or anyone who’s faced similar challenges with their trucks.

What I’ve Noticed

  • Cranks multiple times: When I turn the key, it cranks for several seconds before the engine finally catches.
  • No warning lights: There are no warning lights on the dash indicating any problems, which makes it even more puzzling.
  • Weather doesn’t seem to affect it: I’ve tried starting it in different weather conditions, and the issue persists.

Possible Causes?

I’ve done a bit of research and found a few possible causes that might explain this issue:

  • Fuel system problems: Could it be that the fuel pump is struggling to deliver the required pressure?
  • Battery issues: Is the battery not providing enough power for a smooth start?
  • Starter motor: Could there be a problem with the starter itself?
  • Ignition system: How’s the spark plugs and ignition coil holding up?

What I’ve Tried

  • Checked the battery: The battery seems to be in good condition and holds a charge well.
  • Fuel filter: I haven’t replaced the fuel filter in a while, so that’s on my list to check.
  • Drove around: I’ve taken the truck for longer drives, thinking maybe it’s just a case of lack of use. Still no luck.

Call for Help

If anyone has experienced this issue or has any tips on what to check or try next, I would greatly appreciate your input. I’m really hoping to get this resolved soon, as it’s quite inconvenient to be cranking the engine multiple times before it starts. Thanks in advance for any advice you can share!

I’ve had this issue with my '15 Silverado too! It cranks for a while before starting, especially when it’s cold. I suspect it might be the battery or fuel pump. Has anyone checked their battery health?

3

Exactly! My battery tested fine but I still wonder if the fuel pump could be failing. It definitely cranks longer and longer.

You guys should also look into the ignition system! If anything is faulty there, it can cause cranking issues as well. A lot of people overlook that.

5

Great point, pstone! I hadn’t considered that aspect. I’ll definitely ask my mechanic about it. Thanks for the tip!

I’m feeling your pain with this one! Sometimes it feels like an eternity waiting for it to start. Wonder if it’s a common problem with these models?

It really does! It’s like waiting for a slow movie to finally get to the good part! Anyone tried replacing the fuel pump yet?

8

I haven’t replaced the fuel pump yet, but I will if it doesn’t improve. I also read online that sometimes the key fob battery can affect starting. Crazy, huh?

Totally! I replace my key fob battery just to be safe. If it helps, great! If not, I’m out three bucks. Better than dealing with endless cranking!

That’s a solid plan, meagan92! I might just do that myself. Can’t hurt to eliminate possibilities, right?

11

Everyone’s sharing great advice here! I wonder, is this issue more prevalent in cold weather?

12

I noticed mine struggles more in the winter. Cold affects the battery’s ability to provide power, or so I’ve heard.

13

In conclusion, while it may be a plethora of issues at play, consolidating our insights will help tackle this cranking issue. Let’s keep each other posted!

14

I’ve been dealing with the same issue on my 2015 Silverado! Have you checked the fuel pressure? A faulty fuel pump could cause excessive cranking.

15

That’s a good point! I also suggest inspecting the spark plugs. Worn plugs can really delay starting.

I had a similar problem that turned out to be an issue with the ignition switch. Sometimes you need to wiggle the key a bit before starting.

17

Interesting! How did you diagnose that? I want to be thorough with my checks.

18

You might also consider using an OBD2 scanner to check for any stored codes. Sometimes the computer can provide valuable insights.

19

Great idea! I’ll grab one this weekend. Any specific codes I should look for?

A common code to watch for is P0340, which relates to the camshaft position sensor. It can cause starting issues if faulty.
