Lately, my car has been taking longer than usual to start. Yesterday was a good example because in rained all day here in MA. I figure it would have been moisture(water) in the lines. It could also be dirty injectors but the car runs smoothly. I added Chem-tool to a full tank of fuel. The cars started great this morning.

Have you guys had good luck with Chem-tool in the fuel tank?

Thanks for your replies.

 

In almost 6 years my Max didn't start easily two times. Fisrt time I didn't know what to do and called the dealer, who told me to give gas padel a little step. I did that and it started the engine right away. Second time I did the same and it started. Those two times were not in the very cold winter. After each hard starting, I used some fuel injector cleaning stuff bought from Costco. I don't remember the brand. I don't know the chemical helped or not. Except for those two times, the engine starts in almost no time. Usually I don't stop the key at the notch right before the start and wait for fuel pump to build up something? I just turn it all the way to start.
