MY WONT START UP.

2006 Nissan Titan • 70,500 miles

I have a 2006 nissan titan.I started it up today drove it down the road about 2 mile and got on the hightway. Everything up to now is normal.I get on the highway and it just dies. So I get on the side of the highway and put it in park and try to start it up again, it sounds like it wants to start but never does. The battery icon comes on, the low oil pressure comes on and the check engine light comes on.I have to get it towed back home. I get it and try again to start it and it turns over and sound terrible, like a bogging sound and putters out and dies again. Do you know what is wrong?

Check the fuel pressure and get back to us.

The only way to check the fuel pressure without finding a test port is to have the trouble codes checked.
There is a specification for fuel pressure, but there is not a designated port to attach a manaul test gauge to. Repair failities and dealerships have special tools to check pressure if there is not a safe testing port. However, you can usuall find somewhere on the fuel rail where you can insert an adapter, which would come with test gauge, to check fuel pressure.
Advance Auto and other large auto parts chains have loaner programs where you can borrow tool including pressure test gauges. You might also buy a Haynes maual as they work around these types of issues for the do it yourselfer and show where a test port can be found.
The normal fuel pressure is, (350kPA at idle).
Otherwise a repair facility should not charge more than a half an hour to give you the code and what it means.
Another item you can test on your own is to check if the fuel pump relay is working. When you turn the ignition switch to the, "ON" position the relay will turn the pump on for 1 second to prime the engine. There is a flexible part of the fuel hose that you can pinch while someone turns the key to the ON position. You will feel the fuel pulse in the line if the relay is starting the pump. If it does not then the relay needs to be replaced. Even if it does, you should still check the fuel pressure.

I reccomend you have the trouble codes checked at a repair facility and have them check the fuel pressure if you are not familiar with fuel injected systems as the fuel pressure is bery high and can be dangerous.
