On newer fuel injected vehicles you will usually need a new wiring harness and engine computer to match the engine you are putting in. You will also need various sensors for the new engine such as mass airflow sensors and intake air temperature sensors.

1995 Buick Roadmaster won't start again after sitting Mechanic says no fuel getting pumped but this is an intermittent problem doesn't happen every time Any ideas on sensor issues?
You need to most likely replace your fuel pump wiring harness. It is located in the gas tank connected to the fuel pump. While your there you should also replace the pump and sock. Note the configuration of the old wiring harness when you pull it out because the new one you get is a generic one made to fit different cars. You WILL have to rewire the new harness to make it work.

Will a 2005 4.0 sohc 4x4 Ford Explorer engine work in a 1995 Explorer?
Yes, but not easily. The PCM will need to be changed and the engine harness may be different. If you have a OBDII port under the dash, it won't be too had. HUGE difference in power, well worth the work if you are considering the upgrade. The biggest problem is the PATS key, your old system (in the colum) won't interface, you will have to get a custom tune to bypass the PATS, upgrade the colum or bypass the PATS with a good transponder taped in the colum.
