is there always pressure when taking off the gas cap? Does it relate to a full reading on gas guage?
The gas gauge measures the level in the tank by a float lever, not by pressure. So this doesn't affect your gas gauge. The overpressure in your tank is completely normal. Gas has a relatively high vapor pressure, which means it tends to vaporize easily and even builds up a pressure when enclosed in a tank. Modern cars have to avoid the emission of fuel vapor into the environment. They allow some overpressure in the tank which also reduces the rate of evaporation. If the pressure is too high, it is released through a active carbon filter.

2003 Hyundai Santa Fe will start then die. Then it will not start. After pumping the accelerator or holding on the floor and returning later it will start. Nothing codes out. This happens probably 15% of the time. Any ideas?

A friend has an older Miata that was improperly stored for at least three years. Most of the time, it was not garaged. The gas is old, the battery is dead, it has not been started. It was probably parked without an oil change. He is looking to do the minimum to get this sellable, so the primary concern is the initial startup and the brakes. What would be recommended , especially regarding that first engine startup?

I’ve asked a few mechanics and DIYers this question and so far no consensus. Let’s say you’re 1000 miles away from next SCHEDULED oil change, and you’re about to leave on a 2000 mile road trip. Would you choose to change your oil 1000 miles early before the trip, or 1000 miles late after the trip?
