You have a short somewhere. A fuse is a protective device against too much current. A spike in current indicates a free flow of electricity through the fuse. No way should the ecu be drawing more than the fuse can handle. A short somewhere would draw a LOT more power than the fuse can handle and would blow the fuse.
NEVER replace a fuse with a higher amperage fuse. Use only the recommended size fuse. If it keeps blowing, you still have a problem. Fuses are cheap, burning your car to the ground will be expensive.

the horn switch in the steering wheel could be defective or the slip ring in the steering wheel itself.

there is a carbon brush there that could have worn out.

i hope i fix ur problem.

SOURCE: Driver side door won't lock electronically

very common problem is the door lock actuator. i would recommend replace that. a good idea also would be to remove the door panel and check all the rods that connect to the assembly and make sure one didnt pop off.

1992 Isuzu rodeo 3.1 no spark I have change almost everything that I can think of except for my ecm relay could this be at fault ?

1992 no spark on all 6 cylinders.
ok, did you first look at the schematic on ECU and SparK>?
lets do that and see. now.
spark systems are vastly changed, from 1990 to 2000
evolutionary, that means I must look up what's there first.
lets tick them off.
1: fuses good, means test them if they L**k good.
there are 6 fuse here , for this to work. 2 for ECU relay.
2: head lamps work (bright, ok battery seems strong) and cranks.
3:key on , cluster glows, and all those warning lamps, but but the CEL it must glow, or the ECU has no power, the ecu fires the coil via an Ignitor so ECU must have power and CEL glows
Check engine light.
if that work the engage the diag jumper wire clip
this enables flash diagnostic codes.
then crank for 5seconds, if you get the code for dead CKP bingo.
how do to that is here.

now your relay question?
key on, all wires on the relay go hot 12vdc.
but the black wire (its ground)
the 2 green wires on relay must be 12vdc, output to ecu. the inputs are fused x2

to test a so called good looking fuse.
we use 2 methods, ill show 1.
ohms. with your DMM set to Rx1 range (lowest)
measure he fuse. 0 ohms good, infinity bad.
we use volts on key on car, 12vdc both sides of fuse.
there are some rare exception on that, (fused grounds)
but not this car.
the fuse related are hot all time, or hot keyon.

I have a 1992 geo tracker. It is blowing the electronic fuel injection relay fuse.I can replace the fuse after cool down and it will run awhile and blow.

which engine, 8v or 16valves??????
wrong fuse name, its IG-coil or FI. (be clear, it matters)
use correct names please.
there are 2 prime causes, seen 100 times on real suzuki forums
tracker = vitara=sidekick.
ECU caps short.
or the fuel pump is sucking way too much current
4amp is normal on the pump pike power line (real data)
the ECU on 89-95 all had/have bad huge internal capacitors.
that love to leak, short and or explode.
if they have back skins and say Rubicon on side, bingo , TRASH CAPs.
in the real world i can be lots of things shorts.
all wiring on all cars, can short. vibration and time, and bingo.
automobiles use poorly made harness clamps is why.
(unlike air craft,)
here is the 16v wiring (tossed coin for you)

i bet you, FI fuse 24 blows, right?
and is here, see it.

top fails are
1: ECU caps.
2: 02 sensor heater wires shorted, melted , last guy forgot clamps.
3: Distributor hot wire shorted to engine body, bad service.
4: fuel pump or its wire shorted.

i use an magic tool called an AMMETER to find which of the 4 pathes are shorting,
but on all G16s, we pull the lid on the ECU first day get car
and check for cap leaks, or cracks.
fix the leaks now, or the ECU will burn up.$$$$$$$$$$$$

for fun , see one guy here now with cap death.

the 02 wires are like a 1 second inspection
the distrib wire, 1 second glance.....
the ECU screws, are a #3 huge Phillips screw, and tight.
the first link above as a section called ECU pull.

is car 2door or 4?
is car 2wd or 4.?
is car stick or auto.?
is engine 8v or 16valves. ?
all matter, all wiring is different by those factors, every inch.
tell more get more.... as always...

the 8v has black painted head, TBI
the 16v has silver head that yells, 16valves. MPI
which is it?

there is a page dedicate to this. for 10 years+

read that.?

Integration relay

check the lamp itself to be sure it isnt burned out... check the main fuse and relays under the hood... check for bad wires throughout the lighting system (time consuming and tedius)

My Suzuki areo fuel pump is not kicking in and making buzzing under hood even after changing pump.Already checked relay.

i see you are guessing?
did you check all engine related fuses? that be first.
with a $20 DMM volt meter , the guessing ends.
the electrics form 2 paths,
1: power
2: ground
if either are bad, the pump fails. (suzuki love to do this)

when you turn the key, the ECU/PCM , energizes
the fuel pump relay,
if you have no power to the relay the relay will be dead.
the relay then passes pump power to the pump, on the pink wire
on most suzuki's state side (no location stated)
the pink wires goes hot (12v) for 3 seconds each key on.
if not the relay is bad, or the power to it is bad or the ECU is bad.
if you lose ground to the relay , the ecu or the pump. the pump
will be dead.
using a voltmeter allows you to find this simple failure.
lets pretend the pink wire is hot.
you key on, pink goes 12v , for 3seconds but the pump is silent.
1: the pump has 2 wires , not 1.
one or the other is open.
2: if you see 12v on the pumps ground wire for 3 seconds key on.that means the pump ground is dead open.
the voltmeter will not lie to you , use it and find the problem easy.

I have an 89 ford ranger that i cant get the fuel pump to run. i jumperd after the relay and from after the relay the pump runs. i cant get tghe relay to work at all and i even put a new one on.

Hi, if the car runs with the jumper wire, maybe the wire from the ECU is bad. The pump is powered by the 30 amp fuse #1 in the box under the hood. The relay coil is powered by the EEC power relay, and receives it's ground connection from the ECU. If fuse 1 is good, odds are the relay is not getting the ground signal. You can verify this by connecting a test light to the positive battery terminal and probing the relay socket. The pump terminal will dimly light the test light, and when the key is on the ground signal from the ECU should make the light bright. If you don't get this light, either the ECU is not turning the pump on, or the wire from the ECU is bad. Going back to my first question--does the car run with the jumper? If yes, I would guess the wire is bad. If no, I would say there is a reason the ECU is not trying to turn on the pump--like maybe a security system or safety interlock. An easy way to force the relay to come on is to cut the tan/light green wire from the ECU and ground the side that goes to the relay. The pump will run when the key is on, but the ECU will noit be able to shut it off. Please let me know if you have questions.

I was driving down the road when all of the sudden i smell burning plastic.I pulled over turned my radio down stepped out popped the hood .I didn;t see any problems i cranked my car and my radio was dead...

arent you still under warranty?! check the positive terminal of the battery(common gm issue). check the wiring at the starter motor and look for burned wires. if there is consider the warranty. BY THE WAY, IF YOU HAVE HEAVY SMOKE AGAIN, DO NOT "POP" THE HOOD! IT CAN CAUSE AN AIR FEED AND POSSIBLY IGNITE A FIRE IN YOUR FACE. ive put out car fires in iraq. its not fun getting or treating people for burns. let me know if you need further assistance. cheers

Check the wires with the car in reverse and the key turned on, use a meter. On cars the black is usually the ground but you need to check to be sure.

Radiator fan on my 1994 toyota camry

there are actually 3 temp sensors. 1 is on the top of the engine that goes to temp gauge in dash has 1 wire. next to it is a 3 wire sensor for engine control and choke. on the bottom of the radiator next to the hose is a 2 wire sensor. loosen all 3 but leave connected. get engine hot past halfway point on dash gauge. with ac off disconnect 1 sensor at time. start with 2 wire under radiator. it takes the most abuse. fan will come on when you disconnect broken sensor. 2sensor must agree for fan to stay on till engine cools when turned off. note this is solution i used after verifying fuses, fuseable links and relays worked.WOO HOO! make sure you check both the fuse box under hood and fuse boxleft side of steering wheel my ECU fuse was inside my bros was outside.ECU B on my car goes to nothing and is under hood. Had it confused with ECU on wiring diagram.DOH!
