1991 sidekick,xjl alt blew up battery replaced both now wont start,checked fuses good, turns over no start.any ideas

cranks but wont start.
only a shorted starter can do that.
or alternator gone nuts but that blows the 60amp fuse seen here
you can do lots.
first and always first. check all fuse, (TEST THEM)
I had a car back in 1972 that (mech, really alternator reg)
that went nuts and blew up every lamp in car, at midnight far from home, in a bad neighborhood too.. scary, but engine ran.
your car is EFI,
and is only safe up to 15VDC< over that you blow up ECU
or if lucky (only the 3 ECU fuses blow)
is the CEL lamp working in the cluster,? if no the fuses blew.
the 3 fuses are
IG coil
and dome.
there are 50 reasons for no start but based off one fact
i say fuses.
testing fuses. matters
if they look bad the are,
if they look good, they can be in fact bad,(called hairline cracks)
we test them did you? really test them,i do it live using a voltmeter
the meter NEVER EVER lies.
see? using a meter avoids going down the wrong path to H3LL.
(dog chasing tail)
now what if you measured the 3 power pins on the ECU behind
left speaker (sold my 91,4wd/2door, restored by me)
the ECU has power, (i have the schematic)
if it has power, the CEL must glow, or the ECU was burned up.
1991 are all 8valve cars, then
simple schm.
full set.

starter. /charge.

1992 isuzu rodeo has no spark I have changed the coil , the rotor , the spark control modual , the ecm , the pick up coil , still no spark could it be the ecm relay ??

double posted, why?
I guess you are h3ll bent on gue$$ and not testing.
so keep going replace everything, we love to watch.
why not use the diagnostic jumper as posted in your other posting.
no spark out of coil right.
recap of last answers.
fuses, good, all 7 for ecu +spark good????????
we test them not guess, but ones that look blown are.
CEL Glow key on,?
flash codes ok 5 seconds cranked.
CKP good , the ECU will tell you its bad with flash codes.
why skip this key test??????????????????????????

The ECU must have power ! this is first. not changing out tons of stuff, 12vdc power,, and there are 7 fuses.
i bet you never tested them
or measure all ecu power pins to see if its has power first.
and is FIRST, no brain,(ecu)no spark and then no fueling.
if the CKP is dead, there can be nos spark.
I can only presume you connected a good new spark plug
to the actual coil tower point, then ground the spark shell.
and cranked and spark really is dead, 100 years, same way.
if dead, check 7 fuses.... seen in the book on car.
log in to mitchells diy. (google that)
and read how it works, its all there, read it.
a schematic to.

Cadillac ecu

    • 1 Turn the ignition switch to "Off."
    • 2 Pull down on the top of the fuse panel lid beneath the steering column. Remove the fuse panel lid.
    • 3 Grasp the fuse that is labeled "ECM" or "ECU." The inside of the fuse panel lid shows a chart indicating where each fuse is located.
    • 4 Pull the fuse straight out of the fuse panel to remove it.
    • 5 Turn the ignition switch to "ON" without starting the engine. Leave the Cadillac in this state for five minutes.
    • 6 Turn the ignition switch off.
    • 7 Replace the fuse into its slot in the fuse panel. Press in on the fuse until it is fully inserted. Replace the fuse box cover.

Where is the body ecu located

Engine ECU is located in the engine bay, on the driver side(RHD). Body electrical has no ECU (earlier models). Citroen Berlingo uses what is called 'Multifunction Control Modules'. It has 2 of them. One is located in the steering column switch assembly and the other is incorporated inside/underneath the fuse/relay frame in the engine bay. If your Xantia is late model, it may adopt the Berlingo system but I have not seen one that does.

Efi fuse blows when car strts wher is the efi located

NO YEAR stated (old post)
there is no EFI fuse. sorry,
the ECU has 3 fuses.
FI, Dome, and IG-coil
all 3 run the ECU.
i do know what you ment.
but knowing the correct name makes reading the FSM better.
my guess 2 is you lost the fuse box cover and cant read the names.
guessing year at 91 -95

the ECU fuse blows page. is here

top reasons.
shorting fuel pump (they pull 4amps normal) if 10amps or
more they blow the fuse and or causes the ECU to click relays
like mad.

Trying to locate the ecu . the problum is we got 12 v to the injectors but they are not spraying gas .

check the fuel pressure to injectors to see if pump is working properly. there should be a schraider valve on engine fuel line under hood to test this. the ecu is located on floor directly behind radio. there is a black cover with 2 round plastic snaps that cover ecu. from drivers side, ecu is beside gas pedal. pull on the ecu cover to remove it. are all fuses and fuel pump relay ok !!
