Welcome to the forum

Do the 50/50 test
Spray fuel, gasoline or ether(quick start), into the engine and try to start, key on
If it starts and dies you have a fuel delivery problem
If it doesn't start then its a spark problem
50/50 instant results, no guessing

Lets us know

And what year Ranger?
And manual or automatic transmission?

 

it's a 88 5 speed manual. I noticed there's two sensors with nothing plugged into them. Also have spark fuel pump starts when I jump relay
