Hello,

I just had my daughters 2.0L Vin"P" rebuilt in her 2003 Ford Focus. I am getting ready to fire it up for the first time on Tuesday 12-16-14.

I would like to assure it fires on the first start.

I have been thinking that I should pull the fuel injectors and clean them via the way youtube videos show by cycling them with a battery while spraying a cleaner into them.

This car never had a problem starting before.

Is this a good or bad idea?

Thanks,
Kenny

I've used the exact same technique on the V6Mistakes 24lb injector upgrade. Just use new o-rings.

Seems to me your way is clear.............why go looking for trouble where none existed? Fuel injectors don't clog simply sitting there and if car ran fine I see no need to touch them and then car not start to make you wonder if you messed THEM up. There will be enough guessing going on at a no start already. You can always do them later.

Fuel injector cleaning unless POSITIVELY PROVEN as needed is highly overrated, I've not cleaned them whatsoever in a long stream of cars. Most who do simply could figure out the other things messing up car that had nothing to do with injection.

I've let car sit more than a year to have injectors instantly go back up as before and no issues. And many more times shorter period of time than that, months at a time usually.

I'd make doubly sure that intake is clean inside to get rid of any previous blowup particles.
