Question about 1995 Mitsubishi Montero
I'm assuming that you have checked all the wires and connectors, even the grounding strap for the engine, and they are OK. In that case i'm sorry to tell you but since the the only thing that would prevent a connection between a reader and an ECU is a dead ECU it means that your ECU has been fried - replace it.
You can get a service manual from here

You will have to test the coil pack,The problem relates to either faulty coil pack or the ecu is not giving command to coil packs .To test the coil pack, remove the coil pack connector out.You will have to test each coil pack connector one by one by ohmmeter or voltmeter.
Once out, look at the area where you removed the electrical plug. You should see a "+" on the back end of the electrical plug. There should also be the letter "B"....
the spot where you see the positive symbol, means that's prong number one on the electrical connector.To test:Turn on your ohmmeter and place the positive wire on the 1st prong in the electrical plug of the coil pack. The negative wire should be touching the middle prong. Verification of the ohmmeter at this time should say "0" aka infinite... if it's anything else, the pack should be changed. Next test: reverse the wires... positive on the middle prong and negative on the 1st prong.... on a new coil pack, it should give a value of approximately 1.3-1.7 mega ohms. If any of the readings are off, replace the coil pack.If coil packs checked out ok then its indication that ecu is not commanding the coil pack to fire as required.It has to be checked and replaced.--------------- Check out.Keep updated.Thanks.Helpmech.

The first thing is to check the grounds, there are many ground wires bolted to the engine and on the intake manifold, make sure they are all hocked up ,the other thing is the tone wheel on the crankshaft, make sure it did not come loose or broke off the crank. this sounds like something went bad if it ran for over an hour and then wont start and has no spark from other coils only the first then it sounds like a wire for ground or the crank sensor tone wheel, and last check the timing belt, make sure everything lines up but the crank sensor tone wheel would be the thing to look at after checking all ground, these are single wire grounds, and important one at that, good day.
