Isuzu Cars & Trucks - Recent Questions, Troubleshooting & Support


You must bring it in for repairs before it goes into Limp Mode. Something is wrong with your Isuzu. The RPMs during regen shouldn't be any higher than 2,500. This process usually takes 30 to 45 minutes. I suspect there may be a problem with the vehicle's computer. 7,000 RPMs is too high.

I don't know but I would guess not - manufacturers tend not to use two if one will suffice and wiring harnesses are usually bought in and are relatively expensive.

The circuit diagrams we consider typical on older vehicles changed radically as electronics and then computers became part of a car. It is most important to obtain wiring diagrams and understand how the circuits work before troubleshooting computerised vehicles.
One major difference with headlights is often the supply is permanent (unswitched) and a black box switches the earthy side when the light switch/dip switch commands it to do so.

It would be easy to see how a person familiar with older cars could assume the wiring of a more modern car is messed up...

Assuming there is no visible damage to systems it is probably the fuel pump inertia switch has tripped and needs resetting.

Many vehicles are fitted with a safety switch to cut the power to the pump if there is a collision. Vehicle handbook should provide the location which typically is in the engine compartment, the luggage compartment or behind trim in the passenger footwell, but realistically could be anywhere...

don't break the brakes, it can be dangerous.

easy
the alternator regulator is bad or being lied to and goes nuts
and OVERVOLTAGE condition.

use a thing called a Voltmeter, 15v max.
if more?, lamps deal early death.

Check sensors or clean out maf

Hi.

If problem is only on startup and when idleing, then the problem is likely IAC system, also a vacuum leak will cause the same problem.

If problem is not only on startup and idle, but also when driving, then MAP sensor and EGR system must be checked.

Check also accelerator cable state and setting.

The first thing to do is pulling out the OBDII fault codes stored in the ECM. This is done connecting a code reader to the ECM diagnostic port. The job can be done for a small fee at any local garage, and it is done for free at AutoZone.

The codes will help locating the problem.

About possible faults:

Problem is stalling when idling and during startup, but engine idling fast all the time. Problem not starting at times it is due to the fact that the wrong mixture is being sprayed, this is probably causing flooding and misfire. Since the CEL is on, one of the codes returned is probably misfire.

Check accelerator.

Check IAC system. This is composed by a valve and a solenoid that check and control amount of extra air air when the engine is idling. The IAC valve is located on top of the throttle body.

Check the vacuum system and try cranking with gas tank cap off. Vacuum system is tested using an hand tool gauge onvacuum lines while spraying card cleaner on the hoses (or heating them with a torch). If there is a leak, pressure will go up. A big leak will also do hissing noise, and will often result in a lean code when doing an OBD code scanning.

This kind of symptoms can also be caused by weak wiring to MAP/MAF sensor (MAP in this engine).

If the car also drives very rough and is revving up and down in a weird way, check the EGR valve.

As first thing I would do a code scanning. This car is OBDII. The scan can be done for free at the nearest Autozone, or for a small fee at any garage.

If you get any OBDII code from the scan, report it here, so that we can individuate the possible reason for the problem.

If you repute my solution helpful, then please take some times to accept the solution. Providing good repair tips requires time and skills, and your feedback is important for us.

Regards.

Ginko.
