Nissan Repair: 1986 nissan truck 4x4 king cab, fuel pump relay, truck 4x4

Question
The truck starts to "chug", not getting full power from gas, the next day it won't
start.  Both days it has been bad weather, not known if it's a coincidence.  
Engine turns, battery is fine, new starter in, grounds checked.  Turn and turn,
won't catch to start.  Coil checked, Distributor cap checked.  Is it weather
related?

Answer
Megan,

I would check the fuel pump, fuel pump relay and for the presense of fuel pressure at the fuel rail.  Second, I would use starter fluid and spray a little in the filter box.  Then, replace the filter and start the truck.  If it starts you know you have a fuel related issue.  Nissan's are known to act up in cold weather.  So, get a fuel dryer additive and fill the tank with premium gas and give that a try if all else fails.
