The csd relay kicks and cut the current to the heater plugs and pump when i connect the upper temp sensor isuzu 4ja1, 2.5l turbo what could be the problem, pump and injectors are reconditioned?


what car ?
what year.?
what model car.
what country, (engine and fuel system vary by,,, country)
Bakkie means Austrailia, we are USA forum and dont have the car here, nor books on it, what is uses for injection cant guess.

why not post to a "Australia isuzu forum".. and get fast accurate answers. Goggle that and bingo, it hits. in 1sec, flat.

the books are not free. isuzu sells them in your country
if you ask on Aust, forum maybe someone has the book and can scan it.? for you?

seem like it needs major electric work.
why not go to Isuzu and buy the book, and have all that,....

I have a 1987 Isuzu Impulse turbo with a T3T4 turbo and intercooler installed. It won't idle. Accelerator to the floor is the only way it'll stay running. What will fix this?


well if car is stock, is it? is PCM stock and matches your turbo?
no engine stated. 4Ez1 or 4xc1, 4zc1-t (my guess last one)
there is also a EZ1 turbo too...
we start with basics.
did you run the diag flash codes yet? jumper?
ALDL pin 1 to 3. for code 12 (ok) 3 is ground wire.

Right?
1: compression ok. 150psi on all cyl? min?
2: spark timed right?
3: cam timed right?
4: all sensors reading right? (scan it for bad reading sensors?)

i can see there is no MAF sensor, so is MAp BASED
IS YOUR 2 BAR MAP READING RIGHT.?
are all these parts stock???? and matching your setup?

the map and IAT ,(and pcm tables) are used to calculate all fueling rates. The map is baro sensor. air pressure (called vacuum)
and the pressure drop, is what causes fuel rates to rise.
turbo or no turbo.

if car is not stock now's that time to fess up. ?
and full spec. of whats there. as we can not guess any of that.

the 4zc1-t
i see it has an I-tech unit and an turbo controler
and and air modulator, device, (no clues to what it does)
id recommend buying a REAL FSM to work on this complex setup.



25852667-qtce4npyt0vcvgrmwdzgcqbf-3-0.jpg

or login to alldata.com and read that huge section on diagnostic.
i see it injects in pairs too. (PCM does that)
and has DIS wasted spark coils.

Is the fuel pump electric on1988 Isuzu p up


ok no engine stated. cant help much if you can show VIN or engine name.
we can't guess the following
  1. engine
  2. if carb or EFI (1988 in usa they had carbs and EFI in 1 year)
  3. country, sorry, no country no joy, as varies by that.
why not just look, lets do this simple task.
  1. look at engine, its a carb or just throttle body, ?
  2. is the fuel lines to injector (s) and follow it to tank) it arrives at a filter, go past filter to tank and see a fuel pump rack in tank and 2 wires to rack and 2 to the fuel level sender, so 4 wires total that is EFI there. and is Electric pumps on all gas engines.
  3. if carb, it can be electric or mechanical off cam. drive. same deal see that fuel line it goes to 1 or the other, if electric it has 2 wires, not its pure mechanical.
on older cars there are 2 EFI fuel lines, a loop its called.
1 is like 30psi feed line an the other is just return. 0psi.
1 example of just 2 1988 engines.
he D1 is carb (dang carbs., LOL)
the E1 is EFI.

I need a diagram where the starter is located at on a 92 Isuzu rodeo 6cyl


the starter can only be at 2 points.
the left side or right side of engine
just the most casual looking finds it.
v6, what displacment? gas or diesel?

2.3 L 4ZD1 I4
2.4 L C24SE I4 (GM, Aus)
2.4 L C24NE I4 (Euro)
2.6 L 4ZE1 I4
3.1 L LG6 V6 (GM)
3.2 L 6VD1/6VD1W V6
2.5 L 4JA1 diesel I4 (Cameo, TH)
2.8 L 4JB1-T turbo diesel I4
3.0 L 4JH1-T turbo diesel I4
3.1 L 4JG2 turbo diesel I4

which one?????? omg....

to learn about your engine, use the real name, above is list of all
used world wide (USA smaller list but you never said)
my guess is the GM LG6 common in USA.

using GOOGLE,
and searching for LG6 and starter
i land on this GM site.
