Why does it randomly shut down while driving?

Have you ever changed the fuel filter?

spark plugs or a loose wire.

You can't rule anything out yet. It could be a plug or injector among other things, but probably not low fuel pressure. If you have a code 300 and nothing else, you may have to wait until the problem gets bad enough to set additional codes. And if any of the sensors fail, such as the cam or crank sensors, you'll get a code for those to be tested.
Have the plugs been checked or replaced in the past 30,000 miles ?

My 2006 Liberty has a similar issue. The oil light beeps and then the engine shuts off. I put the car in park and it restarts and the oil light goes off. I had the oil, filter, and lines checked and everything checked out. The mechanic thinks it may be the oil sensor going out and that for safety reasons the engine shuts down when the oil light comes on.

Sounds like your battery cable may be loose or not properly attached, try tightening the cables down on the battery posts.

have you put a new set of plug wires on it. use a spark plug tester, and put it between plug wire and dist, cap. if it is sparking you will see it. if yes and not to plugs put on new plug wires. good-day ! if above checks out. remove dist, cap and see if shaft of dist, is turning. some of the hondas have a plastic type drive gear on bottom of dist, shaft. that goes bad.

may have a slightly warped valve.

The first thing you should do is to locate the oil pressure switch/sending unit.

It's a single wire terminal with plastic connect sensor from the engine block.


This switch serves two functions.

1) provide oil pressure reading

2) disable the fuel pump relay in event of oil pressure loss.

When this switch is failing to provide the correct pressure to the ECU. The wiring harness can overheat and eventually create a short.

ECM1 fuse blow is because the harness is grounding/shorting.

DO NOT drive the truck until you change the oil pressure switch.

After you change the switch,you should spend sometime to inspect the wiring between the fuel pump relay,ECU and fuel pump.


Please post up day on the comment window/page.

I will follow up on it later.


Good luck.

Check you IAC Idle air control valve, check your EGR valve. If both check out ok. Then make sure that the glow plugs are glowing properly if this is diesel, if this is gas check altornator and spark plugs.
