All the gauges are working fine it just won't just wont start, could it be the fuel pressure regulator? Or computer module? As they is no fuel from the fuel pump to the injectors?

it could be the sensor you should look at the oil pressure relief valve
SOURCE: In my 1996 jeep grand cherokee the oil pressure
might want to check the ignition control (the key) did same to me but with volt gauge
SOURCE: 2002 Jeep Grand Cherokee 4.0L oil pressure gauge reading too high
if the gauge starts a 0 - goes to 1/2 , than full - sounds like gauge is OK - seems to me like the sending unit is bad - you could try removing the sender and trying to clean out the port with "brake clean", letting it dry than re-installing it. the pressure switch is still the least expensive place to start
SOURCE: What causes the oil pressure gauge to fluctuate on
If the oil pressure is good and there is no engine noises then the oil pressure sending unit is the problem.Just replace it and you should be good.Hope this helps.Good luck.
