Where is the ECU (engine control unit) on 98 Isuzu Rodeo
try posting VIN code 8th digit for V6,
so we can see exactly which one is there, then give right answer
or RTM?
there are no places to have any ECU tested, sorry, the tester is like $50,000 tool, ask CARDONE< how, or read their how we do it page,
i say leave it alone before you wreck it and are now out $500 for a rebuilt ECU. most bad onces are owners hotwiring them. or worse.
i can see you didnt scan it first and check fuses.
: 1. all instrument lights come on when I connect the power
good but only the CEL lamp matters here, and if dead fuse blown.
2. My speedometer reads 0 when I am moving and only registers when I let up off the pedal (what pedal?)(
how can you do that , with dead engine, pushing it? towing car?
why not say how? first. but is not important yet, below is.
speedo is a toy, speedos dont run engines. (yes help but not run)
3. the car/truck will not start, even after replacing the alternator and recharging the battery.
but cranks fast, why not say that. unless push started with ,m/t box.
2nd gear. IT CRANKS OR NOT? use word CRANKS
and means starter spins and it then in turns spins my cranks shaft seen with EYES on crank pulley, (details do matter)
my guess is you should have posted
VIN 8th digit.
then said fuses all ok. tests.
and engine cranks but does not start, help.
next is spark are all 6 ok>? does it have cop coils
1 or 2 dead, or all 6, BIG TIME DIFFERENT NEXT choices
called DIAGNOSIS and testing logic, (in our heads)
so next is scanning it,
using a scan tool, got one? if not ,you get to do this the long hard way, why do that? or worst spend a fortune in parts guessing
guessing has a bill, and is near $1000 in parts, is that fun?
i can do the pre 96 scan tool free with my scopes./
this line flummoxes me.
"The car stayed on even after I removed the key."
what in the world does that mean,
starter motor stuck one
engine stuck on
lighting of anything stuck one, (remove word car and put a correct word there, cars is not it. sorry
my guess engine will never run
and starter sticks on
or lighting sticks one of some kind.
tell more get more.
