So i got a bottle of gumout professional: complete fuel system cleaner 1 step. Does this clean dirty fuel injectors aswell?

And also, does a 5 second crank start on a cold engine sound normal?

I'm not familiar with the product. We had a system that connected to the fuel lines and ran straight through.

The 5 second crank is longer than I've ecountered.

Well, it may not be actually 5 seconds. Its more of a 12345 as what I counted. I would say possibly 3 full seconds. I think its either a dirty fuel filter, or dirty fuel system. May even be caused by a dirty MAF sensor. But I dont have to re-crank the car at all. Its just when the engines cold, not after it has been drivin and then waiting 10-15 minutes and go again.

After researching, I have found out that complete fuel system cleaner cleans:
injectors, intake valves, and combustion chamber while you drive.

Hope this helps!

Yea, I just answered my own question

Let us know how it does.

Alright, will do. Although, just because it doesnt work out for me, doesnt make this product worthless, as I am not sure if the reason for extra cranking with a cold engine is because of a dirty fuel injector. I will update with more progress when I start to see it. Thank You.

I've had good luck with the Chevron fuel system cleaner. I ran a couple bottles through the car when I first bought it and it helped with cold starts and brought my gas mileage from a terrible 18 mpg to a slightly less terrible ~19.8

UPDATE!

So after driving the car with the complete fuel system cleaner, I have driven ~58 miles, and I am still just now getting off the full bar. It seems to be working good. It still has a little bit of a longer cranking time, but I havent really driven that much. It seems to help the fuel injector, i had a bit of a delay when i would step on the gas, but it is improving. It only does it sometimes now. I will give it another couple of days and update whats going on.

UPDATE#2

Okay, so I drove a tank down and got ~207 miles, I filled up at 1/8th a tank. The CEL came back on. Went to the mechanic, cleared the code told me to run some more system cleaner through it after tank is down to 1/8th next fill up. Same code as I had in earlier thread. Car is great though.

Stuff works for mpg

UPDATE3!

So, my CEL came back on, I went to the local mechanic, and it WAS a dirty MAF sensor. I knew it, and could have cleaned it myself, but $85 later my car is running great and starting right up.
