Question about 1998 Buick LeSabre

3 Answers

Where can I get the wiring diagram for a 1998 Buck LaSabre? I am interested in the part on the ignition switch/starter motor area (where I am having problems) Thanks! When I turn the key to Start, the starter motor does not turn over, but if I jump the heavy yellow and purple wires, it does. If it does start, it almost immediately dies as if the fuel pump were then shut off. All relays and fuses are ok. Battery fully charged.

Starter enable relay is under the hood in a fuse box that runs along the bottom of the windshield wipers, there are (2) twist knobs and (1) wing nut in the far left hand corner of the fuse box cover. remove cover. now you will see a group of smaller fuse box remove covers and look inside there will be I.D. to tell you which is which.

Looking at the end of the solenoid on top of the starter, the battery cable hooks to the larger stud on the top "12 o'clock". A smaller purple wire connects to the smaller terminal at 3 o'clock and the stud at 6 o'clock connects to the flat wire coming out of the starter. The purple wire comes from the neutral/park safety switch, which is fed by a yellow wire coming from the start relay which is fed by a yellow wire coming from the ignition. The start relay is also controlled by the Pass Key decoder module. Hope this helps, as for starters.
Check the fuel pump relay

The fuel pump relay is located to the right of the glove box.

Remove three 8mm screws (along the front edge) and a wingnut (drivers side near the accelerator) to loosen the insulation panel. Twist out the light courtesy light and using a pair of pliers squeeze the plastic nipple to remove the SIR. Remove the insulation panel from the vehicle.

After the insulation panel is removed, the fuse/relay panel will be to the right of the glove box. The insulation panel should have a diagram of the fuse/relay panel layout.

The relay should be in the left column of relays just above the fuses.

Why once I have driven my 1998 Ford Explorer XLT and the motor warms up and I turn off the switch. The ignition will not turn over. I can. Crossout the cylinoid and it starts automatically


Hey Opie , how are thing's in Mayberry ? Ha Ha Ha , bet you get that a lot .
The ignition will not turn over. You mean the starter will not turn over ? When you turn the key to the start position nothing happens ? The starter doesn't spin the engine .
Could be a few reasons . High resistance in the starting circuits . Do you have and know how to use a volt meter ? Doing voltage drop testing on the starter motor , cables .

Starter Voltage Drop

Looking at a wiring diagram and testing the control side of the starter circuit , relay ,ignition switch , wiring etc... Do you know what a wiring diagram is and how to read one ? Video's on youtube showing how to understand diagrams . Here is a web site for free wiring diagrams . http://www.bbbind.com/free_tsb.html
Enter vehicle info. Year , make , model and engine size. Under system click on engine ,then under subsystem click on starting . Click the search button then the blue links one at a time . Do you have a manual or automatic transmission ? Could have a bad clutch switch if manual trans or park neutral safety switch with automatic trans .
Check out some videos on basic automotive electrical testing .

Will not turn over! Starter won't engage!!


When you turn the key to on, do the dash and warning lights come on? This would verify power to the ignition switch.

It's like this: you have a positive battery cable with a lot of juice connected to the starter, but not to the starter motor. It is only connected to the starter motor when the start wire out of the ignition switch energizes the starter solenoid, mounted on top of the starter.

So you check the small wire to the starter for power with the key held in start. If it has power then, the starter or the solenoid is probably bad- as long as the battery is charged and the battery connections and starter connection is good.
If you have no power on the small wire in start, trace the start wire back to the ignition switch. You may need a wiring diagram- there is often a start relay, a park/neutral safety switch with automatics or a clutch safety switch with a manual transm., and sometimes a "crank" fuse. All or some may be in the path of the start wire from ignition switch to the starter solenoid. You would need a voltmeter or test light to check this circuit. If you want more help, post back with make, model, year, and engine, and I could look at a wiring diagram for your start circuit, or I could post a link for you to see the diagram.

Due to part availability, this recall is being conducted in three phases. Phase 1 will consist of 1998-1999 vehicles, phase 2 will consist of 2000 vehicles; and phase 3 will consist of 2001 vehicles. When sufficient parts are available to notify customers of 2000 and 2001 vehicles, you will be notified and will receive a new initiation report.
Recall - Ignition Circuit DefectCondition
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 1998 model year Buick Skylark; 1998-2001 model year Chevrolet Cavalier; 1998 model year Oldsmobile Achieva; 1998 model year Pontiac Grand Am; and 1998-2001 model year Pontiac Sunfire vehicles. If the engine fails to start and the driver holds the key in the "start" position for an extended period, high current flows through the ignition switch, and sometimes produces enough heat to melt internal switch parts. If the switch is damaged, a fire could occur in the steering column, even with the engine off and the key removed. The fire could spread to the interior of the car, which could injure occupants of the car or cause damage to adjoining structures.

On a 98 buick lasabre it does not start, battery is good, starter works(but no power to exciter wire when cranked), starter relay fine. I was wondering what was left to check, fusible link, park neutral...


Park neutral safety switch , try moving gear selector to neutral . If that doesn't let it start ,viewing wiring diagrams an testing the starter electrical circuit's with a DVOM - digital volt ohm meter .

What color is the wire leading out from the PCM to the starter?


There is no wire that comes out of the PCM to the starter. It's a completely different circuit that emulates from the Ignition Switch on the steering column...(which is still interchangeable with General Motors). However, the color of wire that attach's to your starter will either be a solid 14 ga.Brown wire or a 14 ga. Light Green with a Black tracer on it, dependent on which engine you have.

Wiring Diagram 1998 Chevy S-10 starter replacement


The starter has one large cable from the battery positive, and a wire that goes to the solenoid (Part of the starter) that becomes hot when the key ignition is turned to start. This also passes through the neutral safety switch. (So it wont start in gear) Not sure if this is what you need, a little vague.

1998 454 engine wont start. starter replace selonoid replaced.


Items of interest.

1.When a starter fails to start a vehicle, and the wiring has been found to be bad, and changed, one suspects the wiring first.

2.If a starter is suspected to be bad, one takes it out, and performs a benchtest, or takes it to an auto parts store, and see if they can do a benchtest. They need to load test it, not just see if it will Spin!

This test result should stop the needless buying, of starter after starter. If you get three bad starters in a row from an auto parts store, I suggest it's time to change auto parts stores! (Make sure, you are not twisting the S terminal on the Solenoid, when installing the ignition wires)

3.The frame of your vehicle should be the Ground.

Make sure that the motor home manufacturer, hasn't reversed the system for this motor home, and is using the frame for Positive.
This was done in the past for some older vehicles, because it was thought to reduce rusting, of the frame. However, you're dealing with a motor home. Hard to say what type of system they used.
Normal, would be using the frame as a Ground.

In the normal type of setup, of using the frame as ground, make sure where the starter contacts that 454 Chevy engine block, that this area of the starter has no paint on it. The starter grounds through the engine block, and where the starter contacts the engine block.

Make sure also, that this area of the engine block has no paint on it.

Be sure that there are flat braided ground straps going from the frame, to the engine block. If they are an insulated wire, and not braided flat straps, be sure they are about the thickness of your little finger. You'll notice I stated -> They. There should be TWO of them. ONE, will NOT Do!

The frame is the ground. The starter gets it's Ground source from the engine. The engine gets it's ground source from the frame. The only contact the engine has to the frame, is the motor mounts, and the transmission mount. They have
RUBBER in the middle!
There HAS to be -> ground straps! There MUST be TWO of them for the correct amount of grounding!

4.Power to start the starter turning comes from the ignition switch. The reason you have a solenoid on the starter, is so that there won't be a wire that is the thickness of your little finger, going up to the ignition switch!

Check the wire that comes from the ignition switch, for power, once the ignition switch is turned to the Start position.

Battery -> Negative terminal disconnected. Ignition wire from starter disconnected. Put electrical tape on the terminal end, of the ignition wire you removed from the starter solenoid. (Goes to the -> S <- on the solenoid)

Leave the other wires on, put the nut back on, and tighten. (Use caution in this area. The nut is only 5/16 inch, or 11/32. This means that threaded post is TINY. DON'T overtighten! IF, the threaded post starts to turn, STOP! Pull out on the post.

Inside the solenoid cap, that you can't see, there is a square boss, on inside end, of this tiny threaded terminal post. The solenoid cap, has a square hole that this boss fits into. Keeps that tiny threaded post from turning. Inside the cap, the tiny threaded post is connected to a one strand copper wire. If you twist the tiny threaded post, more than 90 degrees, the wire will twist off! Time for another solenoid!

Wheels chocked. Transmission in neutral, and it's best to have the parking brake on, and someone in the drivers seat. Have this person hold their foot down on the brake pedal. This way you avoid any accidents happening to YOU, someone else, or property.

Reconnect the Negative battery terminal. (Order of connecting up a battery is ALWAYS, Positive terminal First, Negative terminal last)

Take a multimeter set it to DC, and to the 50 volt scale. Find a clean, non-painted surface on the frame, (Or scratch a little area), touch the Black lead, (Negative probe) of the multimeter to it. Touch the Red lead, (Positive probe), of the multimeter to the ignition wire, electrical tape partially removed. (Enough so you can make a good contact to that terminal. The tape is there, in case the wire slips out of your hand, and touches a ground. If it has no tape, you'll think it's the Fourth of July under there!)

No reading? Be sure the person inside, has the ignition switch in the starting position. Still no reading? Check that ignition switch out. See if it's getting power.
