Do i have to change the injector pump after changing the ecu kit in ford currier 1.8 td

which engine? i cant guess engines, not today, too early.
what will be, will be..... fate always wins... and entropy.
so that is just 2 simple tests.
12vdc (11v cranking) to the pump , across both its 2 pins?
yes, /no of no work to ECU relay (fuel pump relay)
if the relay shows 12vdc cranking and pump
then we check fuel pressure, next.
but that is all wrong..... what do we really do, as all EFI systems can cut fuel for many reasons, besides that pump.
ill guess its a gasoline engine, and still stock end to end. (blind too)
1: head lights glow bright , key off. and cranks fast on demand.
2: key on, the CEL glows, in cluster, it must or ECU lost power.
3: fuses to ECU and pump good...???? all fuses good.
4: i connect scan tool (any tool works in usa, here) at the 16pin DLC port seen near knees of driver. i get comms now. if not say so.... if no comms now, the ecu is dead.
5: I crank for 5seconds release key and if scans show DTC errors of
P03xx codes, now you know why injection is halted, by design.
all cars do that, if up to 3 things spark wise are bad, the ECU cuts all injectors dead. (prevents crash and burn, as seen on TV by law)
so if all that is OK,?
6:then i look and see if injector 1 passes my NOID light test.
yes, then it is injecting. ECU is....injecting. ok. (did its job)
7: i then check for 12vdc (11v cranking) to the pump, if not?, I trace that wire for its obvious failure or the relay bad.
if you have 12vdc to pump cranking (good)
i check fuel pressure next. using a tool called a fuel pressure gauge that costs $20 (ask)

one could skip to test 6 first. (6 bad, start back at #1)


next time post engine in car.
cylinder count at least and displacement.
the line up, last 2 are diesel...
3.2 L 6VD1 SOHC V6
3.2 L 6VD1 DOHC V6 twin cam.
3.5 L 6VE1 DOHC V6
3.0 L 4JX1 TD I4
3.1 L 4JG2 TD I4

i answered for USA car, and gasoline engine..

this is USA forum, and we dont have this car.
IT'S NOT A USA 2002 DIESEL trooper.
that and exact engine, size.
we have, 3 gas engines, 2.2L,3.2. and 3.5L
here. only and books that cover only those 3 engines.
so if a diesel dies.
what>?
check fuses.
scan it.
check filters
try test fuel to see if it runs on test fuel
test the glow plugs yet,?

if pump pressure is dead,?
check, power to the pump yet? (fuses are first)

there are 4,.6 and 8cyl. diesels by Isuzu.,
which is it>
they have names.
7 diffr. B engines, 3,xxxx liters.
and
5 diffr. 4Jxx series engines.
my guess is the engine is.
3.0 L 4JX1 TD I4
3.1 L 4JG2 TD I4

wiki says.
"
European and Asian buyers could opt for the diesel engine option of the 4JG2 3.1-liter (later superseded by the more problematic 4JX1 3.0-liter of 159 PS or 117 kW)
4jg2 is indirect injected
4jX1 is direct.
apples and orange diffr.! injection classes. '

learn what's under that hood, then fix it?

what country
what engine, real names, not 3L vague-ness. please.

call dealer service and see if its a reprogramming issue..personally I dont have a clue..

it can be your ECU the fuel pump section of it has failed . or your noise relay . has failed.or both.a noise relay give power to the injectors.that information to do so .is from your ECU the cars brain.only way to fix is by changing them.

Injectors may not be receiving signal to open, have you had your ECU Hooked up to diagnostics and checked the injector signal plugs?


(you will need a set of injector test lights, these can be had in a kit for around 40 bucks on ebay, as for diagnostics you may need to take it to a ford dealership or service center if you don't have a diagnostic tool)

i'd say ignition, does it have a distributor cap? or not? they changed around those years... you need to check for spark.

If the plugs, wires, and coil are all good then it can be a partially clogged injector, or low compression on that cylinder. It can also be a bad ECU. My cousin had a 99 Taurus with the exact same problem and it turned out to be the ECU which he had to replace. The ECU is very expensive so make darn sure everything else is good before you replace the ECU. It could be the coil has an intermittent problem and may show good especially when cool. You might try putting that coil on a different plug position, resetting the ECU, and see if you get the same code PO301. Run a compression test on all cylinders to see if you have good compression. Add a can of Seafoam Fuel Treatment to a full tank of fuel to make sure the injectors are clean. Check all wiring closely for frayed wires or loose connections. Eliminate all other possibilities before looking at the ECU itself.

The problem could be in the injection control module. This can be checked by what they call a noid light that can be purchased at a parts house, plug it into the injector pigtail start the car and see if the noid light comes on when it is supposed to fire on that injector if does not then the control module is going bad.

i tink the problem it ur fule pump if its star whit a quick star fluid change ur fule pump and dont forget to change ur fuel filter
