I’m in the same dam boat right now .
I just put a 2002 Xterra motor that was wrecked so I’m pretty sure it ran .! in my 04 Frontier . And had to go without the EGR because the 2002 does not have EGR and now it will not run . It has a new crank position sensor , sensor ,Throttle position sensor, new timing belt everything an I no 100 that’s it’s in timing . And the distributor that came out of that other motor that was running but just had Spun the crank bearings . I have spark have Fuel. Tried three other distributors that I’ve had from junk yard trips . If you figure yours out I’d love to hear what it was .!!
Hi I’m dealing with a similar problem could really use some help I have a 2000 Nissan Xterra was running fun then one day won’t start I replaced all spark plugs and the distributor cap and rotor and just did the fuel pump still no start any ideas
update figured it out everyone check the temp sensor I was getting a code for that it actually if it’s out or faulty will make it so the truck doesn’t start
