The steel tanks on these trucks are a constant source of rust chunks and other junk. I don't know how this got past the fuel filter. I don't think this enough to seriously restrict fuel flow. If it was it'd set P0087, P0088, or possibly both. I'd remove the flow dampers and fuel supply line...

The firewall one. It looks pretty good in there. Does disconnecting the scv make a difference in how it runs? In theory it should still run when disconnected, just badly. The best way to tell if it's bad is to watch it's performance using DX. P0193 in Isuzu literature describes it as a large...

Get the junction box open and connectors apart. Look for corrosion

Get it started and start wiggling connectors. A bad connection at the common rail pressure sensor can cause some misfire symptoms. Scv too. I don't like telling people to buy thousands of dollars of parts on a guess.

Uo101 doesn't mean anything if it's inactive. P0102 and P0113 were set when you unplugged the MAF sensor. P0183 is the fuel temp sensor on the fuel pump. The sensor pretty much never goes bad, so I'd suspect wiring. This will cause limp mode. P0193 is the common rail fuel pressure sensor high...

Is it drivable at all, or does it make zero power?

A scan tool with live data may be essential for fixing this. I'll continue to think about it. Had anything been done to the truck before the problem first started?

Aren't the 'normal' ones around 600 hp?

Does your mechanic have a scan tool that can read engine codes and see live data? What year is the truck?

Did this happen all of a sudden or did these symptoms coincide with some event? FYI, engine data is pulled from the 16 pin connector. I don't know what scan tool you're using, or whether it's compatible. The injection timing is not adjustable. If you disconnect the mass airflow sensor does...

Do you have any backstory on it? Any event that coincided with this symptom?

Did the ground wire from the battery to frame break? Send me the VIN if you can

I don't have a definition for that code, either. Weird. Are there any symptoms besides extended crank? And how extended is the crank before starting?

We don't have this model in the US so I don't have any parts info for you.

One of our customers has an older Mitsubishi. Its got around 650k miles. It runs great. The problem is that they are much less common than other trucks, so you might struggle to find competent mechanics to work on it. I spent several hours replacing all the brake lines with Nicopp tubing because...

I recently worked on a truck with a leaking fitting on the fan clutch. You couldn't hear the large leak over the engine noise, but when you cut the engine off the fan clutch solenoid turns off, stopping the leak. With the engine at a low idle the compressor couldn't keep up with the leak, so...

I'd check the brake switch adjustment first. Its super easy to check and it can cause an instant power-no power situation.

Was this problem resolved?

The first thing I'd check is the brake pedal switch.. If it's out of adjustment it can intermittently cause no power. If you're flooring it, it could go from no power to full power in an instant. When the brake pedal is released, the plunger on the switch should be fully depressed. If it's not...
