You have bad electrical wire somewhere. The tap temporarily makes the contact.

Check the ECM B fuse. If good, try removing the connector from the oil pressure sensor and shorting the terminals in the connector with a paper clip. If this gets the pump to run, replace the oil pressure sensor.

Okay... anonymous, The first... easiest & cheapest assumption is your IGNITION KEY has become damaged and is intermittently FAILING... Simply having another key to try should tell if that is TRUE/FALSE... ~~ (Caution) After that the BEST THING TO DO is to make sure all your battery connections are fresh & clean. For most of the sane world... this is not a big deal... but AS for me... I think static SPARKs and losing battery... is a HUGE problem ( you should always know all the CONSEQUENCES OF REMOVING POWER in ADVANCE of so doing ). ELSE You need to consider your BATTERY (both sides). ((Body, frames & engine ground distribution ALSO)). What I am about to propose can be seriously damaging if done improperly... (extreme caution) IF I am understanding you correctly... "all dash lights radio 4WD selector switch leds are extinguished" The most likely source of your issues is your PRIMARY (large cable) POWER & GROUND... This THEORY can be disproved... when the CONDITION is FAILURE MODE... Make sure the vehicle is fully secured & NOT in gear... (as all your SAFETY switches are being BY-PASSED)... When the CONDITION recurs... Apply BATTERY directly to the "S" (start) terminal of your starter SOLENOID your starter should engage (good enough). That single test says your primary battery & ground systems are OKAY... leaving you to consider the LOGIC portion of your vehicles starting system & OBD systems. ~~ FREE circuit drawings & TECHNICAL SERVICE BULLETINS (TSB) for popular USA market vehicles can be viewed at BBB Industries (registration is required as these are real Manufacturer's DOCUMENTS) at: BBB Industries Premium Alternators Starters Power Steering Products Hope this helps...

The Bose system is complex - it has an amplifier separate from the Bose compatible radio. This amplifier takes low level audio signals from the radio, not full driver outputs from a replacement radio, and by trying to use the replacement radio you may have blown the amplifier. If that is the case, you may not be able to go back to the original radio. The only option you may have with the replacement will be to find the Bose amplifier and bypass the connections to feed the replacement radio outputs directly to the speakers. This may not be as simple as it sounds, as distribution to the various speakers comes from the amplifier, not the radio, and the wiring from the amplifier to the radio may not have all the wires you need. Before going on, you had better get a wiring diagram for the Bose system (service manual or Alldatadiy.com).

What kind of vehicle is it?

Rather then guessing if there is water in the fuel , take a sample . If there is water in the fuel the water will be on the bottom an gas on top . Water is heavier . Disconnect fuel line at the fuel rail an cycle the key a few times , collect the sample in a glass jar . Let it sit for 5 mins. If there is water in the system it will be able to see for sure .

not computer because you got good reading from the wires check firing order for the engine as the ht leads could be crossed the injectors could be blocked at the tips , or leaking under the seals

I don't know if this is procedure you followed? There is door lock receiver under the dash. The receiver sends message to bcm the bcm controls the door lock/unlock relays accordingly. Any applicable trouble codes?

Temp may just be your temp sensor, look through the drivers side front wheel, you see the sensor. Fuel gauge not working is usually the sending unit on the fuel pump. Gotta drop the tank.

You mean EGR?? It's right in front of the engine on top,next to the thermostat.
