If you look at the relay it has a wiring diagram on the side of it, showing the power wires (recall 87 being one of them) and the control wires. Can't tell you color, perhaps a Toyota tech could but in my experience they vary.

SOURCE: 87 toyota pickup 4x4 22ret i have no injector

OK, the computer grounds one of the curciuts on each injector to pulse it.
Interesting information from alldata, the autodata and mitchell and Bosch AFC all show a code 11 as being ECM (B+) that I have, which could be the EFI main relay, fuse, fuse link or wiring (usually one of the wires on the battery terminal have broken off or corroded and lost connection)
Here is the diagram I have for Bosch AFC on Toyota PU, I'm not sue it will be readable compressed for upload but here you are

SOURCE: STARTER DOESNT START ENGINE EVERY TIME IT CLICKS

This is a starter solenoid issue. The best way to fix it is to change the entire starter, but there are solenoid repair kits available to fix just the solenoid. The rest of the starter is old, so it won't belong before it will have to be replaced anyway. I just do it all at once and be done with it.

Do you have a volt meter ? How to voltage drop test starter motor circuit Here is a site for wiring diagram http://www.bbbind.com/free_tsb.html Enter your vehicle info.Year, make , model , an engine size. Then under system click on engine , then under sub system click on charging system (starter system is also under that ) Then click the search button , then click on the blue link . You can issolate the starter circuit at the starter relay in the under hood fuse box , to see which side of the circuit is bad , control or the load (starter) side . If you pull the relay out of the fuse/relay box an look on the bottom you will see four numbers 86, 85 & 30 ,87 .If you were to take a piece of 12 gage wire an jump where 30 & 87 plug into the fuse / relay box . And if the starter spins the engine over you just eliminated the starter , battery cables , ground circuit as not being the problem . This would indicate that something on the control side was bad , Park neutral safety switch , ignition switch . But before replacing parts some electrical testing should be done . Hope this helps an if you have an questions let us know .

Tip

My car starter motor does not turn over.


Hi.

If you do not have any power at all, and the dash is not turning on, then check the battery connections, and the connection from battery ground to the engine body.
Also ensure you have tested the battery. Read the voltage across the positive battery terminal and a ground connection on the engine body. It must be around 12.5V
If there is no problem in there , then the problem is the ignition cylinder. The ignition cylinder can be tested reading voltages at its contacts. This in case there is no power at all.

If instead the dash is turning on, but the starter motor does not turn over, then there may be more reasons for the fault.

To start, look for the starter fuse. This is a large fuse, probably a 30 Amps. Look also for a5 or 10 Amp fuse to the ECU/PCM (main car computer module. If any of this fuses has blown, it can cut power to the starter motor.

After testing the fuses, check the starter relay. This is usually located in the fusepanel under the hood, or under the dash. The relay must click when the key is turned. The relay can be tested in fullusing a Volt meter or an Ohm meter.
The starter relay can also be tested swapping it with a relay of the same kind.

Fuses and starter relay are the most common failure when the car dash comes on, but the car does not start.
If this test good, ensure that the anti theft system is not armed (starter should still turn over by the way).

If fuses and relay are good, read volts at starter motor, while machineis cranking. You will need to use Voltmeter on the contacts at theback of the starter motor solenoid. If there are 12 Volts at startermotor, but motor does not turn over, then starter motor or startersolenoid is faulty.

The starter solenoid can be tested using an Ohmmeter at its contact. Ifthe solenoid is bad, reading with multimeter set on impedance, it willhave no continuity (it will read infinite Ohms).

If there is no volt, or volt is much below 12 Volts, then the problemis either the ignition switch located in the steering column, or aproblem concerning wiring from ignition.

The ignition switch can be tested jumping its contact, reading Volts orOhms on its terminals. To access the switch it is necessary to takeapart the steering column.



Regards.

Why wont vehicle turn over


Is the anti-theft light lit ? Is the starter relay good ? Do you know what a relay is ? Are the battery cables good ? I would start will the starter relay circuit's if the anti-theft light is not lit.! The starter relay along with the starter relay diode is located in the battery junction box in the engine compartment. The relay is K-22 . If you pull out the relay an look on the bottom of the relay you should see four sets of numbers 30,87 an 85 ,86 . If you take a jumper wire (12-14 gage ) an jump pins 30 an 87 if the battery cables & connections are good the starter will crank . Pin's 85 &86 are the control side of the relay . One of these comes from the ignition switch when is start position an the other goes through the transmission range sensor (park neutral switch) To ground or the PCM if yours has a V-8 . Now if when you jump pins 30 & 87 an nothing happens you have bad connections or the battery cable is bad . You can go on youtube an check out videos on voltage drop testing the starter circuit .

It just wont start i turn the key and there is nothing the fuel pump comes on but nothing else and i have tried everything i can think of. the only way to start it is by doing a rolling start.


Check signal wire from starter to either solenoid or start relay. Make sure signal wire is connected to starter properly. One side of the start relay leads to the starter the other to the ignition switch. Check sinal wire is connected. If so test signal wire w/ tester. Ohms setting. Test relay ohms setting. Relays usualy dont go bad. Test ignition switch w/ tester. DC voltage 12 volts or greater. Black terminal to neg or ground. Red terminal to ignition switch side of relay/solenoid. Turn ignition swich to start look for voltage reading. Depending on the vehicle it could be anywhere from 6 to 12 volts. If no voltage reading somthing has failed on the ignition switch side of relay. A relay is simalar to a fuse and will be housed w other fuses under the hood. Also all fuses should be checked. This can be done w the ohms setting on tester without removing the fuse. Look at the top of the fuse there are exposed points that allow the tip of each lead to contact the fuse. Only some fuses are like this. Remember signal wire or fuses this is probably going to be your problem.

97 tacoma tail lights and dash light not working. Fuses and relays seem good.


If you can remove the relay, it is easy to test if you have a multimeter (volts, ohms, amps).
A relay is simply a switch that works electrically, using a low current circuit to turn on and off a high current circuit, for example a headlamp or spot lamp circuit that usually draws anything from 10 to 30 amps, and is switched on by a switch designed to handle only 2 or 3 amps.
Typically it has four contacts, but sometimes contacts are shared, and the relay ends up with just three contacts.
To test the relay (once it has been removed) find the low current contacts. This is achieved by switching the multimeter to Ohms, turn it to the lowest reading (200 or less) and probe any two points on the relay. Carry on testing until a pair is found that shows a reading on the meter. These two points are the "pick" points, or the low current circuit contacts.
Placing a 12 volt current across these two points will close the circuit over the other two points. If you can't find any two points that indicate a reading on the Ohm scale, your relay is shot.
If you've found the two points described, connect a wire to each one and connect one to the battery +, the other to the - or earth, and listen for a "click" sound indicating the closing of the contacts.
The high current contacts can still be faulty, so check with the meter for continuity across these points when the relay pulls in.
Please let us know if this helped at all..

30amp auto shutdown fuse blows is it alternater


The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements. The Fuel Pump Relay is a separate relay controlled by the ASD relay input to the PCM. Fuse #12 (10amp) provides 12 volts to the coil side of both the relays and the ignition switch. Fuse #6 (30 amps) supplies 12 volts to the output side of the relay. Fuse #16 (15 amp) from the relay output to the Oxygen Sensors and Fuse #26 (15 amp) relay output to the PCM. Fuse #24 (20 amp) is Fuel pump relay output to fuel pump. Fuse #19 (10 amp) supplies 12 volts direct to the PCM.
look for burned or melted wires in the offending circuit.
sounds like you wiggled a wire while installing new relay.

My 2006 buick lacrosse wont start radio and lights work but its not saying nothing when i try to crank it


Hello! Do you hear a click when the key is turned?...If no click is heard either the ignition key, the Crank relay, the starter, or the battery are suspect...Having lights and radio does not mean the battery is capable of running a starter motor......Put a meter on the battery...should read 12.5 volts...Turn key...Does voltage drop to 8 or 9 volts? Bad battery...If all is well with battery and connections to it...Check the starter fuse # 33 in the under hood fuse/relay box...If the fuse is good that click you should hear is from the Crank Relay in that box...If all of the above is OK connect your meter to the Purple wire that is connected to the starter motor...When the key is turned 12 volts must be on that wire...If there is the starter motor is defective...So, #1...Do you hear a click when key is turned...That would point at a bad starter or weak battery...#2...If you do not hear a click bad fuse #33, bad Crank Relay, bad ignition switch...#3...If fuse is good Bad Crank Relay or Ignition switch; Crank Relay is a low cost item ($10)...Replace Relay...Stop there and send a comment as to results...Guru...saailer

Hello! Sounds like a defective Throttle Positioning Sensor (TPS)...Bolted to the throttle body with a four wire connector...(one lead for the air flow meter)...We are interested in three of those wires...Wire colors are: Brown/Black=ground...Green/White=output...Green/Black=5 volts...
Using two safety pins push the points into the rear of the in-place connector into the Brown/Black and Green/White wires...Clip the (+) probe of the meter set to read 5 volts to the Green/White pin and the (-) probe to the Brown/Black pin...Start the engine...At idle meter must read less than 1 volt (.85)...As you increase the throttle the voltage must rise smoothly to 4.5 volts at full throttle...If it does not the TPS needs to be replaced...See photo below...Guru...saailer

1996 plymouth grand voyager wont start


It could be a number of thing's , wouldn't think the battery cables or connections . If they were bad it would have started in the first place . Timing belt ! There again , it wouldn't start in the first place . The crank sensor would not have anything to do with the starter spinning the engine over . The fuel pump will only run for two seconds when the key is first turned on , this is to prime the fuel system ! The fuel pump will not be turned on again untill the engine is cranking , or running . The fuel pump is controlled by the PCM - engine computer through a relay (fuel pump relay) Samething for the starter control , has a relay . Testing for control of the relay ,.at the relay ! In the under hood fuse / relay box ! Find the starter motor relay an pull it out an look on the bottom , you will see four sets of numbers . 30 , 87 & 85 , 86 . 30 should have B+ volt , testing with a volt meter . 87 goes down to the starter solenoid . If you take a piece of 12 gage wire an jump these two spots in the fuse / relay box , the starter will engage if the battery , cables an the starter are good ! The other two 85 & 86 are the contol side of the relay .86 should have B+ voltage an 85 goes to the PCM , where it will supplie a ground IF ,there are no problems with the park neutral safety switch . Or also if your vehicle has a anti-theft system an no problems ! Also your vehicle has a relay called a ASD - auto shut down relay , this relay powers up a lot of systems on your vehicle , i would also check it , Relays do good bad .

Hello! I sent a test procedure to you Wednesday evening but It appears you did not receive it ..This is the path for Battery and Ground to pull the crank relay which applies +12 volts to the starter solenoid..Either there is a fault in this path or the starter itself was damaged in the collision...Leaving the ignition switch when in start ...+12 volts on the Yellow wire goes to the Crank fuse (10A)...Other side of fuse is Purple wire to PCM C-2 Pin # 23...+ 12 volts at this point...PCM sends a ground on C-2 pin #76...Yellow/Black wire to crank relay....+ 12 volts from the PCM ABS fuse (10A)...via Park/Neutral switch to crank relay...Relay pulls and applies +12 volts on the Purple wire that goes to the starter...That +12 volts, if there,indicates a starter damaged in the collision...If not there chase it back until you lose it...Would you be so kind as to not rate my solution until the test procedure is accomplished...Send a comment..saailer
