Hi I have a...

Hi I have a 2008 Nissan Titan 5.6l and it won’t start it will turn over but will not start. I check for fuel pressure an there is none so I sprayed some started fluid in the throttle body and it looked to turnover so I figured it was the fuel pump so I ordered one just replaced it an still no fuel pressure. I was looking for a fuel pump relay but I don’t see it can you tell me what might be the problem.

Mechanic's Assistant: How many miles are on the vehicle? And when was it last serviced?

Truck has about 48000 miles

Mechanic's Assistant: Are you fixing your Titan yourself? What have you tried so far?

Yes and fuel pump

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I also changed the crank sensor thinking that was the problem
