I came home a few nights ago and shut off the Tracker. Couple hours later I was gonna leave and it turned over but not start. Little squirt of ether and it started for a second so it’s fuel problem. So I changed the cam sensor and fuel pump. No change! 🤷🏻♂️ Fuel pump relay is supposed to be hot in 2 spots? Mines good in one and .97v in another. Fuel rail isn’t getting any fuel at all. I’m about ready to dump a load of tannerite on the dash and 💥 ... It’s gotta be something simple doesn’t it?

Simple is perhaps a relative term.
It starts on ether so it's a fuel problem - I agree with your diagnosis there, but your remedial action puzzles me - why change the cam sensor, why change the fuel pump? Why not change the fuel filter - that would have been simpler and a lot less work - with possibly the same results.
Once I had established that there was a fuel issue my next step would have been verifying that the fuel pump was good (wire it to a 12V source, and if was investigate the electrical power circuits to the fuel pump.

Seems like every time an engine problem arises (with previous Trackers) it was a cam sensor. I took the one off my 2000 model to check it. Tank had to be dropped so I figured it’s a small investment to go ahead and change the pump and strainer. Original was clean and overall the inside of the tank is spotless. The original pump still works too. 🤷🏻♂️ I’m reasonably sure if I can get voltage to both relay prongs... I don’t know if I’m reasonably sure of anything to do with it really. Seems like it has to be a bad connection. But where?

Have you checked fuses? If you are missing power to a terminal on the relay, it is probably a fuse problem. I believe the ECM controls the relay via the ground. Are you missing voltage from the "supply" terminal of the relay, or the "coil" terminal?

I’m not sure. A buddy was laying in the floorboard with the leads and I was reading the display. I can double check it for sure. Thank ya!

There comes a point when you have to recognize your limitations and choose a way forward, sometimes the way forward means paying a professional to do the job.
Most automotive relays have either four or five terminals, so if it's only got "two prongs" then it's not a relay. A relay is an electrically controlled switch, one that uses a small current to control (switch on/off) a large current. Typically there is a coil of wire, which when the control voltage is applied, becomes a magnet that pulls a lever that closes the relay contacts switching them on - you need to figure out which are the coil terminals and which are the contact terminals before you can test the relay - easy way out in this case is to put the volt meter on the pump terminals and crank the engine see if you get power there, if you don't then you need to get to the technical stuff.

It’s 4 prong. We were testing the plug in in front of the fuse panel. The bottom of the 2 relays there. My shop of choice is booked for the rest of this week and next week closed for vacation. 2nd choice is a little short staffed and has 10 in front of me. Which could eventually turn into more than 2 weeks. Not sure how extensive those repairs or upgrades are being done. They do quite a few turbo VW diesel conversions.
