Isuzu Recent Questions, Troubleshooting Help & Support

Question edited for clarity. Turbos are a disposable item, just like a battery. After a certain number of years you replace them because they wear out in the hostile environment of super heated exhaust gas. You could remove it and strip it down, and you will likely find that the bearings and seals are worn. $237 for a new one https://www.google.com/search?q=1998+Isuzu+2.8+DT+service+turbo ..

When the brake booster light and brake light come on after replacing the batteries in a 2017 Isuzu NPR Diesel, it could indicate a problem with the brake system or a malfunctioning brake booster. Here are some steps you can take to troubleshoot the issue:

1. Check the brake fluid level: Low brake fluid level can cause the brake booster light and brake light to come on. Open the hood and check the brake fluid level in the reservoir. If the level is low, top it up with the recommended brake fluid and check if the lights go off.
2. Check the brake system: Inspect the brake lines, brake pads, and brake rotors for any damage or wear. If the brake pads are worn out, replace them immediately.
3. Check the brake booster: The brake booster is responsible for increasing the force applied to the brake pedal. Check the brake booster for any damage or wear. If the brake booster is malfunctioning, it will need to be replaced.
4. Reset the brake booster light: If the brake booster light and brake light stay on even after checking the brake fluid level and inspecting the brake system, it may be necessary to reset the brake booster light. To reset the brake booster light, turn the ignition switch to the "on" position without starting the engine. Pump the brake pedal 3 times, then turn the ignition switch off. Start the engine and check if the lights go off.

If none of these steps work, it is recommended to take the vehicle to a certified mechanic or the nearest Isuzu dealership for a professional diagnosis and repair.

I can suggest that you check the owner's manual for a fuse and relay diagram, or you can try contacting an Isuzu dealer or a qualified mechanic for assistance with the issue you are experiencing. They may have the necessary diagrams and experience to diagnose and fix the problem

The timing settings for the Isuzu 320 V6 engine will depend on the specific year and model of the engine, as well as the type of timing system it uses. However, here are the general steps for setting the timing on a typical Isuzu V6 engine:

1. Remove the timing cover: Start by removing the timing cover to access the timing components.
2. Locate the timing marks: Locate the timing marks on the crankshaft and camshaft sprockets. The marks may be visible on the sprockets themselves or on the timing cover.
3. Rotate the engine: Use a socket and breaker bar to rotate the engine until the timing marks on the crankshaft and camshaft sprockets are lined up as specified in the service manual.
4. Check the tensioner: Check the timing belt tensioner to ensure it is properly adjusted and functioning correctly. If the tensioner is worn or damaged, it should be replaced.
5. Adjust the timing belt: If necessary, adjust the timing belt tension by loosening the tensioner bolt and moving the tensioner until the belt is at the correct tension. Then, tighten the tensioner bolt to secure the tensioner in place.
6. Reinstall the timing cover: Once the timing belt is properly adjusted, reinstall the timing cover and any other components that were removed.

It is important to follow the manufacturer's recommended procedures for setting the timing on your specific Isuzu V6 engine to ensure proper operation and prevent engine damage. If you are unsure about the correct timing settings or procedures, it is recommended to consult a service manual or take your vehicle to a qualified mechanic for assistance.

I found this on JustAnswer This is a link to the service manual. It is too large to upload here, so it is sent to the cloud where you can download it. The relay diagrams are on pages 8-56 through 8-71. That is chapter 8 and pages 56 through 71. https://acrobat.adobe.com/link/track?uri=urn:aaid:scds:US:387250f1-9d35-3e81-8681-5c5579d2cfed Hope that helps and thanks for using JustAnswer and let me know how it works out.

t is possible that a 4bc1 Isuzu engine may fit in a Bedford Elf truck, but it would depend on various factors such as the specific model and year of the truck and engine, and any modifications that may be required to make the engine fit properly. It is recommended to consult with a qualified mechanic or expert in Isuzu engines and Bedford trucks to determine if this engine is a compatible and appropriate option for your specific vehicle.

is this AFRICA KB240 , 2.4L petrol.????????? we have no KB here in USA not a one. no parts, no books on it. (heck no WIKI on KB. ouch) so it starts and drives ok/ but idle surges (up/down RPM) means PCM can not control IDLE RPM at all, and has many causes. you can drive it fast and even up hills or at WOT.? but only stopping at say a stop sign the engine surges. well lets work that 1 problem if is just 1. EGR struck open, is common. (if has one) IAC stuck the idle air controls valve is stuck and needs cleaning, of gunk off it thermostat not bad, 180F (82c) is good but 150 is bad. hot normal engine. VVT failing . if has VVT. (cam timing variable) VVT engine most times have no EGR valve. spark wires bad, seen on new cars with no COPS. seen with COIL packs and 4 HV logs and 4 HV wires and HV wires bad, or just one. as I said no books here on KB at all. zero. as in service manuals.

Here's one owner comment...

Re: Frontier 320 V6 fuel consumption
Hi Garreth,
I get between 6.2 and 6.8 km/l in town if I drive carefully. On the open road this goes up to about 8,8 km/l.
Recently hauled quite a load and it dropped to about 5,5 km/l.
By the way - Hunter : thanks for that valuable bit of advice ...
The best option seems to just have a good check and tune done.

Interigate the ODB port and that will give you a clue. Could be wheel speed sensor or anything including Cat issues.

The fuel pressure at the fuel rail with the engine off on a 2001 Isuzu Rodeo with a 3.2L V6 engine should be around 0 psi, as there is no fuel being pumped into the system. As for the fuel pressure specification at the factory, it is typically between 35 to 45 psi (pounds per square inch) with the vacuum line to the fuel pressure regulator disconnected and the engine running. However, the exact specification may vary depending on the specific model and configuration of your vehicle, so it is always best to refer to the service manual for your particular make and model for the exact specifications. It's important to note that fuel pressure can be affected by a variety of factors, such as a clogged fuel filter or a faulty fuel pressure regulator, so if you are experiencing issues with your fuel system, it is always a good idea to diagnose the problem before attempting to adjust the fuel pressure.

found and engine in a garage sale.(on a pallet)? no car told, or year or model or VIN the book is by CAR /TRUCK name, and VIN and year. or google it. get lies. do you build engines by internet rumors? try youtube https://www.youtube.com/watch?v=kVIzSbsoECo

This could be a sign of a failing braking system. It is possible that the brake pads are worn out and need to be replaced. It is also possible that the master cylinder is failing and needs to be replaced. It is best to have a certified mechanic inspect the braking system to determine the exact cause of the issue.

NO COUNTRY TOLD OR VIN.SCAN THE PCM FIRST (OBD2) FOR TWB ERRORS. (throttle by wire) DTC errorsscan the PCM first at the OBD2 16pin port, USA scans tools work on this car if car is USA car, not told yet.THROTTLE BY WIRE MUST NOT BE FAILING.WATCH OUT FOR ISUZU PARTS NOT SOLD AT SCALPING PRICES. (some vary rare)yes 3.2L engine not 3.5 or 2.2basic basics (redux after facts told)engine good, compression good yes 175psi (12bar)engine pumps air!, vacuum good, CAT not melted.EGR not stuck open allowed cranking or at idle ever.spark good. yes, has 6 COP coils new spark plugs and the cop coil boots not bad and carbon tracked bad.now test fuel runs. oops forgot that why?I guess the engine starts some or random and when doesback smoke happenswell if FPR is bad, fuel pressure regulator too high does that. smoke. thing.NO IAC idle air valve (separated) it is now part of TB with motor drive throttle. called TBW this year 3.2LIAc was on 1999, now gone.TB = throttle body, all these words xyz are ASE , EFI names. a standard in the USA. IF TB is bad, crank with 5% added foot throttle to add air and now idle is good?this engine has TBW, throttle body ,throttle by wire.we scan the PCM first to see of TB or pedal fails.SO FAR TESTS SHOW:NO ScaNS DONE, AND MAKES THE JOB 10X MORE HARD.good enginegood sparkgood fueling are the test for sure 22 year old cars.on old cars we do all the tests. (lots there are)good fueling includes AIR, or fuel mix fails.the TB ,TV MOTOR DRIVE valve must not be stuck closed. (TV INSIDE TB IS THROTTLE VALVE )the TBW , throttle valve motor , not dead.if you use a scan tool it will tell you of TBW fails.

help with what could be the problem Based on the information provided, it appears that you have already checked many of the common causes for the engine not starting, such as compression, spark, ignition coils, vacuum, and the switch and computer. However, there could still be other issues that could be causing the engine to not start. One possibility could be a problem with the fuel system, such as a clogged fuel filter or a malfunctioning fuel pump. It could also be an issue with the timing belt or chain, which could prevent the engine from turning over. Another possibility could be a problem with the camshaft or crankshaft sensor, which could prevent the engine from receiving the proper signals to start. It's recommended that you take your vehicle to a professional mechanic or Isuzu dealership for further diagnosis and repair. They will be able to perform more in-depth testing and troubleshooting to determine the root cause of the problem and provide a solution.
