Why would a 1999 pontiac bonneville not start?

Engine does not crank and dash gauges, auto headlights and blinkers do not work however radio, blower, wipers and flashers do work. When jumping solenoid engine cranks but does not start.

Going to be bad ignition switch your items that dont work require the key to be <<on<< the items that do work will work on the accessory side of the key.. if the key is <<on<< when you jump the solenoid and does not start it is because the pcm is not powered and the security passkey is not reading a signal.. gm ignitions are common problems on these older cars

SOURCE: 1995 pontiac bonneville stalls

I just went through lots of troubleshooting and expense on my 1996. Whenever I would lift my foot off the accelerator and was below about 30 mph, the rpm's would starts jumping around and sometimes it would stall. If I gave it a little gas (accelerator), I could sometimes keep it running. It also backfired once in a while. Starts right back up. Also, if I let it idle while in part, it would die after 1-2 minutes.

I ended up finding a hole in the fuel regulator. About a ~$70 part if you get an AC Delco, but very simple to change.

SOURCE: 1995 Pontiac Bonneville SSE wont start.

Hello, you seem to have a problem with your anti-theft system the ignition lock cylinder has two wires that are very small and are common at breaking because every time the ignition switch turns the are being rocked back and forth, or either there is a malfunction in your key, but odds are you will be replacing the cylinder. You will also have to have a new key made.This fix is kind of exspensive so I would advise you to let the dealer do it. Besides when putting the switch in it could be possible to damage the new one so let them have that headache. Thank You

Have a 1999 Pontiac Bonneville SE. Turned off while driving, sounded like it lost gas to engine. press gas pedal and it made bogging out sound, like it was flooded. What should i troubleshoot?,

Well Jeff if you think it is flooded I'd start by pulling the spark plugs and see if they are wet with fuel . If they are clean them or replace them. If not wet , I would check for fuel pressure , you can get a fuel pressure gauge at harbor freight fairly cheep. On the fuel rail there is a black cap, un screw it an screw the pressure gauge on to it. Crank the engine over a few times an see what the pressure is, it should be 55 psi. And if you have fuel pressure check for spark, pull off a plug wire and put in a spark test , you can buy one at harbor freight or auto parts store for $5-$10 .If it has spark you would need to do a compression test. You can get one of those for $30 bucks .How many miles does the car have . What engine ? 3800 V-6 this engine should have the timing chain replaced at 150,000 miles . have seen them jump time causing them to die and not restart. Should have 150 to 175 psi compression depending on the ware on the engine. Last one I did when the timing jumped , it bent an exhaust valve .

Headlights flashing at blinker speed

Flickering headlights can get you a ticket to the policeman's ball, but more importantly, they may indicate trouble inside your car. This problem can result from many potential causes, but whatever the reason, you must identify and address it before your lights go out altogether.

If you have a drain on your battery , it would not take 18 months for the battery to go dead . What do you mean The battery gauge in the dash shows only about 1/2 power, When ? When the vehicle is running ? Not charging ! The battery gauge as you call it has nothing to do with the Battery . That's showing how much the charging system is putting .The volt's indicator is controlled by the PCM - engine computer . With the engine running should show 14.1 volts .if your only seeing 7 the charging system isn't working. The alternator is controlled by the PCM as well ! Have it check by a GM dealer .

Verify you have good power and ground at the blower motor if so replace and make sure the wires are not routed near the blower motor.

You could start by checking the maxi fuses that feed the ignition switch. If you don't have power to the fuses feeding the ignition switch, the problem would be between there and the battery. The best tools for finding this type of problem is for me, is a wiring diagram and a test light. A test light is $5 at an auto parts store and you can copy your wiring diagram for ten cents a page at your local library...

Tail lights out as well as dash lights. 1995 pontiac bonneville

you need a head light switch. buy from carquest (significantly less expensive then dealership).
remove knobs (small insert on pull knob press in with a small flathead while pulling towards you, twilight knob pops right off)

take off the cover plate over steering wheel (pop out with flat head screwdriver)

then cover over instruments (small torx bit 5 screws, 2 hidden by previously removed cover).

three small bolts hold in light switch.

1999 Pontiac Sunfire won't even turn over, but the

The radio will work even with a dying or discharged battery.

First, be sure to check all of your fuses in the engine compartment.

A full battery will keep the headlights bright with the engine off. With a dying or discharged battery, the headlights will be noticeably dim.

When you turn the key to crank the engine, does the starter try to turn or make a fast clicking? If so, the battery if low or dying. If it makes a slow click then stops, then it's REALLY dying.

If you don't have a battery charger, go to Walmart and get some jumper cables. Hook up a friend's car to yours. If it starts, then the battery was low, either from a bad battery or a bad alternator.

If it doesn't, you have electrical problems, possibly a bad starter or starter solenoid.
