Wireing diagram for what? What have you changed that you need the wireing diagram for?

  • Anonymous Jul 28, 2008

    Year and model would help to

  • Anonymous Jul 28, 2008

    Have you plugged the wires into the fuse box correctly? If you have removed the entire body and removed the wireing from the vehicle you may have plugged some or all conections into the wrong place. Do you get lights on the dash when you turn the key, and if you do check your engine fuse to make sure you have not blown it. I will see if I can get a full diagram for you, but most times you only get bits and pieces.Then you have to piece them together. And full diagrams can be very difficult to follow especially if you or someone eles has changed or removed wires from the car. Whats the model and type (trayback, wagon,shortback) and country of your jeep, they bring out different types as body styles and countries require different things.

98 Isuzu rodeo, engine cranks and trys to start but it won't

If this is a diesel engine you probably have an air lock in the fuel system. It will need "bleeding" before it will start. If you have already tried bleeding the fuel system there may be an air lock in the injectors. If it still doesn't start I suggest you carry out a compression check because diesel engines need to be in good condition to start easily, especially in cold weather If it is a petrol engine, there could be problems with engine timing or ignition problems.

1998 Honda Accord Won't Start

Park neutral safety switch maybe be the reason for the no crank ! Try putting the vehicle in park ,then try to crank the engine . Testing the electrical circuit is the best way to trouble shoot this problem , along with do a voltage drop test on the starter circuit ! This will test the battery cables an connections .

1990 Dodge Ramcharger won't start. Battery output 12v, voltage across coil terminals 6v, voltage output at coil port to coil wire 6v, voltage of coil wire output to distributor 6v. Engine will c

There should be a small white ceramic block on the firewall - this component cuts the battery voltage from 12 to 9 volts for the coil and ignition system. It has 4 wires and is called a ballast resistor.
You may need a book with the wiring diagram to be able to test it. You should have battery voltage going in and something like 9 volts coming out.
You can also run a wire with a fuse from the battery to the positive side of the coil to check the system. Disconnect the factory wire from the coil first.

I have a 1994 Buick roadmaster , I have a no crank no start issue, the car has a new battery and I changed the starter just in case, however the car still won't start! I read about the security feature...

I am truly stumped!! Help!!! ???? It's not that difficult if you know how to test electrical circuit's using a wiring diagram an a DVOM - digital volt ohm meter . Free wiring diagrams here http://www.bbbind.com/free_tsb.html
Enter vehicle info. year , make , model . under system click on engine ,then under subsystem click on charging system . Click the search button ,then the blue link . Looking at the diagram on the left , i see the ignition switch ,the crank fuse in the I/P fuse box, the theft deterrent relay an the starter solenoid . Using a voltmeter or test light check for B+ voltage at the S terminal on the solenoid while someone tries to start the vehicle . If no light or B+ voltage ,back track to the relay , Test for B+ voltage at pin's 30 & 87 while cranking . If you pull the relay out of it's socket an look on the bottom or side you will see four set's of numbers 30 & 87 and 85 & 86 . You could just take a piece of wire ,heavy gage 12 . Jump 30 & 87 . If the heavy gage battery cable to the starter is good it should crank the engine .

Mini van wont start battary charged new altanator and starter all wires are grounded

Do you mean it won't start, or won't crank.
You should have a neutral safety switch between the key switch and the starter to prevent you from cranking the engine in drive or reverse.
A defective switch would keep the engine from cranking.
A mechanic would check for voltage at the starter on the wire from the key switch and go from there.

2002 Buick Regal won't start

Hi Debbie , Do you know anything about automotive electrical systems an testing ? Viewing wiring diagrams to see what all is involved in the starting system on your vehicle would be the first step ,then testing the electrical circuits for the starter using a DVOM - digital volt ohm meter .
How to voltage drop test starter motor circuit
Starter Voltage Drop
Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. Year ,make , model an engine . Under system click engine ,then under subsystem click on starting . Click the search button then the blue link. Looking at the diagram I see when the key is turned to start it send a crank signal to the PCM - engine computer , if the PCM gets a valid fuel enable & starter enable signal from the anti-theft system it will energize the crank relay sending B+ voltage to the S terminal on the starter solenoid . That is if the park neutral safety switch is OK . You mite try putting the vehicle in neutral to see if it starts then. These switch wear on the inside that could cause a no start problem . You can test from the crank relay ,watch this video VEHICLE RELAYS Operation Diagnosis In the video he uses a horn circuit , your crank relay works the same .

Hi, I have a problem with a 1999 Dodge Ram 1500 series 5.2 Liter. It will crank over but won't start every once in a while it will start and run for about 20 seconds, then it dies and won't start...

check all your vacuum lines. if there is a vacuum leak, the truck will crank, but not start. if you need a vacuum diagram, go to www.autozone.com create a profile it's free, add vehicle. put in the info of your dodge ram. then from the main screen, where it says select a category, select vehicle repair guide. on the next screen select emission controls. on the next screen where it says select a chapter, select vacuum diagrams. as you scroll down just click on the diagram for your engine. hope it helps. good luck.

My 2000 Dodge Grand Caravan will crank but won't start.

Hi, if an engine cranks but refuses to start, it lacks ignition, fuel or compression. When the engine cranks normally but won't start, you need to check ignition, fuel and compression. Ignition is easy enough to check with a spark tester or by positioning a plug wire near a good ground. No spark? The most likely causes would be a failed ignition module, distributor pickup or crankshaft position (CKP) sensor.
