No power going to ignition control module, what would cause this?


Yes, the pink wire to the ICM and from the run/crank relay should have battery voltage in run or start. If not, check fuse 11, a 10 amp fuse in the Fuse Block-Underhood. Also check fuses 38- a 30 amp fuse supplying power to the run/crank relay, and fuse 9- a 10 amp fuse between the run/crank relay and the ECM. All of these fuses are in the underhood fuse block.
Fuse 38-the 30 amp fuse, the power feed for the run/crank relay- will be hot at all times. Fuses 9 and 11 will be hot in run or start. Check for power at the fuses. If the relay is not turning on and sending power to those fuses and to the ICM, and the ECM, (and to the injectors through fuse 16 - a 10 amp fuse), then work back to the ignition switch and the body control module. Wish I didn't have to say that, but yes, the BCM is between the ignition switch and the run/crank relay.
Good luck, Michael.

No want to start,no light check engine on,


Maybe I can give a little help. Do you have the 4.0 liter straight six engine? This should apply as well if you have the V8 engine.

:...no check engine light...:With key on, does the light turn on? If not, it may not be getting power. Have to check that first, check all fuses in the under hood relay/fuse block. The check engine light should turn on with key in on position, just as an alert that the PCM is powered, and ready to work.

"...no electric to coil..." With key on, the dark green/black wire to the coil should have battery voltage. In that fuse/relay block will be a relay called an Automatic Shut Down relay (ASD relay). When the PCM turns this relay on, power is sent to the ignition coil on the green/black wire. The power feed for the ASD relay is fuse 2, a 20 amp fuse in the Power Distribution Center -the fuse/relay block under the hood.

So you have a couple of things to check: Make sure the PCM is powered. If it is, hold your finger lightly on the ASD relay while someone turns the key to on. You should feel it click on. If it does, but no power at the coil, check if fuse 2 is sending power to the relay, and check the green/black wire from relay to coil. If no relay action, possibly a bad relay, or the PCM is not turning the relay on.
Good luck. Let me know what you find.

The fuses are located in the fuse box under the hood, but could be the fan motor too, check if you have power at the motor

None of my wipers work. We were driving in the rain, and both the from and back wipers just quit. I did not check the fuses because they are 2 seperate fuses.


Both the front and rear wipers have a couple things in common. They are both powered by the 'Wiper System Relay". This relay supplies the power to both the front and rear wiper fuses. I would check for power at both of the fuses. If there is no power, then there is a problem with the relay or the relay circuits. The relay and both of these fuses are located in the underhood fuse/relay box. Please note that there is a "Wiper System Relay" as well as "Front Wiper Relay" and "Rear Wiper Relay" Why??? I don't know...some engineer at Saturn worked out his job-security with this one, I guess...

Any way, the Wiper System Relay feeds both of the fuses which, in turn, feed the two other relays.
The primary side of this relay is controlled by the Ignition 2 circuit from the ignition switch, so the relay is energized any time the ignition switch is on. (sounds like a good way to overheat and burn up a relay to me...but who am I??? I am not an engineer, I just get paid to deal with their stupidity)

The secondary side of this relay gets its power directly from the battery...no fuses in between, just a fusiblelink. This link is not the problem because there would be a whole bunch of other stuff not working - including your engine computer.

If I were to take a guess, it would be the relay.

Let me know if this helps you. Take a moment to rate my solution this will let me, as well as other know.

1986 Supra. Head lights pop up but does not turn on.


the headlight pop-up circuit is different from the lights themselves. Check the headlight fuses in the engine compartment fuse box. If the fuses are good then check the headlight relay. It is in the same fuse box just behind the headlight fuses. (The headlight relay is the second relay from the right side of the fuse box. the relay at the far right is the electronic fuel injection main relay.)

The radiator fans in my 1996 Plymouth Vogager is not functioning. The 40 Amp orange fuse for "radiator fan" in the power distribution center is in perfect shape. Is there any other fuse or relay to check...


Check the fuse box under the hood and under the dash, find the cooling fan relay or fuse. Sometimes there are relays mounted to the fan shroud itself. little black square plastic relay 1"x1" roughly. Look inside cover of fuse box for location or owners manuel. Check or replace the relay(s). Possible bad fan assembly though. Check for power.

Why do my headlights not come on when all other lights a re working fine?


There is a main fuse/relay box located under the hood. It may be on either side of engine compartment. Remove the cover and locate the fuses/relays. Each section should be marked as to what each fuse/relay is for. Typically, there is either a fuse or relay for each headlight. They are usually marked with the letters LH (left headlamp) or RH (right headlamp). If there are fuses under each heading, check fuses with a fuse tester. If you do not have a fuse tester, simply remove the fuses and check to see if it is blown. If the fuses are good, the next step would be to check the relays. To do that, with engine and key off, remove a relay from another section (check to make sure the prongs match) and insert relay into headlamp relay socket. If headlamp comes on, simply replace the relay. If the problem still exists, have it serviced by a qualified mechanic certified in automotive electrical systems. I sincerely hope that I was of some help with your problem. Please feel free to let me know of your progress with this situation. Thanks.

Put oil and anti-freeze into the truck,then the truck won;t start. the batteries are new, no turn over at all.


check to see if you have power at the fuse/relay box under the hood. reise the lid off the fuse/relay box and look inside for correct location of the ignition start fuse and the relay. check with a testing light for power to fuse and relay. replace faulty fuses and relay.
