Ok brief synopsis.

Yesterday I got my oil changed and while they had the car up, they mentioned to me that I probably could use a fuel filter change. Due to price, I declined got the rest of the general 3k mile maintence done.

So this morning I run out and jump in my car and turn the key, the engine is cranking but not catching. I figured it could just be a frozen fuel line and let it sit all day. Come back at lunch and still no go. A gentleman happened to notice me having issues with it and pointed out a few things

So brief synopsis.

1) Engine was running fine yesterday. No sputtering.
2) Starter is turning as belts and fans are moving when I turn the key.
3) Car has gas (1/4th tank)
4) Fuel pump is running as I can hear it when someone turns the key from my gas tank

I've noticed my car does have a bit of trouble starting in colder weather but not this bad. I'm pretty sure it this is somewhere along the fuel line but I have no idea how to be positive this isn't condensed water that froze in the bottom of the fuel tank.

Welcome to the forum, I'd use a fuel pressure gage on it. Some of the national brand autostores used to loan fuel pressure gages. You can call and ask. Once the vehicle sits overnight, there shouldn't be much if any pressure on the fuel system. Take the supply line loose from the fuel filter, you stiil need to be aware of possible pressure on the system, aim the line into proper size container, cycle the key on and off, see if any gas comes out?

Also, you can take the fuel supply line loose from filter end and at the engine compartment, see if you can blow air through the line. There is an additive, that you add to the tank to keep the fuel from freezing, if something is already froze, I don't know that it will help. Any testing be safe.
