Check engine sign flashing. i have an auto repair shop and encountered lots of this with isuzu dmax. engine doesn't start. no fuel coming out of the injection pump. please help!!!

Clean throttle body and passages also check egr ports and valve operation. Look for carbon build up and clean with carb. Cleaner spray can if deposits found...do not spray egr valve as if it enters the diaphragm it will ruin the vaccume diaphragm.

as each nut is specially made , getting this will be near impossible
take the vehicle to a tyre shop and they have a method of getting the nut off and then you will have to buy a new set of security nuts
I keep mine in the glove box always not anywhere else in the car.

Check your fuel pressure. Running the pump dry could of damaged it.

check the fuel pump

has the check engine light come on?
is it blowing any smoke when it starts and if so what colour?
has its servicing been kept up to date?
could be fuel related
check and drain water trap filter under vehicle look for any water contamination.
have the fuel filters been changed?
is it running rough at idle?
these had problems with EGR, injectors, and suction control valves as well as lift pump in fual tank that could cause your concern.
how many KM on clock?

could be fuel filter clog.air filter or MAP sensor or an intermittent speed sensor on the transmission

to whom it may concern. my dmax model 2006 3000 cc lately having problem like engine suddenly stop especially when it slow,fuel filter already new fuel line been check but the problem still there.anyone been encountered this problem before what is the problem?

try fuel filter's first, drain gas, add new gas prime the pump and start add fuel dry. most times its just bad gas or water . injectors do go bad but try every thing else first. need more info on what its doing

If the tech 2 device is indicating the code for 4wd module then it has to be replaced.Get the module and its connections checked before going to replace the module.If the module connections are getting short or loose then getting the connections repaired solves the problem.But most probably when it shows module problem,the module has to be replaced.The actual testing procedure is as follows:--- If you have an ODBII code reader, you can check if there are any codes stored in the ECU. There is also a diagnostics mode you can go into for transfer case issues:

1. Warm up the engine. Turn it off.
2. Turn the ignition switch on and off at least twice, then turn the ignition switch to off.
3. Shift into park.
4. Turn the 4WD selector to Auto.
5. Turn the ignition switch to on. Do not start engine.
6. Is the 4WD warning lamp on? Continue if no.
7. Shift into reverse.
8. Turn the 4WD selector to 2WD, Auto, 2WD.
9. Shift into drive.
10. Turn the 4WD selector to 4H, Auto, 4H.
11. Shift into neutral.
12. Turn the 4WD selector to Auto.
13. Shift into park.
14. The 4WD indicator light will come on for 2.5 seconds, then go out. It will then flash a series of times to represent a one or two digit code, with half-second delays within a number and 1 second delay between numbers. e.g. to represent the code 23, it will flash twice with 0.5 seconds between flashes, wait a second, then flash three times with 0.5 seconds between them.Get it rechecked again by disconnecting the 4wd module and reconnecting again,. --------------------Thank you.

First, turn on the ignition, and DON'T crank the engine. Look at the check engine light and see what it does. If it flashes 3 times and goes out, then your problem is not with the Electronic Fuel Injection. If the light keeps flashing, you need to get the diagnostic codes read and analyzed. If the light does not come on at all, then the ECM has either lost power for some reason, or it has failed itself.

Repairs will depend on the results of the above test.
