Sounds like your neutral safety start switch. If you left it unhooked or it came loose it will prevent power from going to the starter when the starter is engaged. I hope this helps. Hooah.

Ok a mechanic came to look at my 1999 cougar says he pulled the heater resistor out and plug it back in now when I turn my heater on my ignition coil and fuel pump to not work they lose power car runs when...


I looked at info for the 2.5L engine. The violet wire at the coil pack is primary voltage, goes hot with on. Use a test light, is that wire hot? If not back track the circuit. Check fuse 4--20 amp in the diagram for voltage, key on, also check if fuse is blown. Note the diagram. Sorry if diagram is a little small, maybe you can enlarge?

did you check for voltage at the coil pack low tension input
this comes from the electronic ignition and the distributer dc setting on a multimeter

check inside the distributer that the little magnet is still in place on the rotor and that the sensor is outputing pulses as it turns over

pull a plug out and place its metal to ground check for actual sparks

Car want start ,it not the battrey car turn on and everything come on


If you are confirmed that battery is seated properly and its fully charged.Then get the battery voltage checked. A fully charged battery will give 12 volts in voltmeter readings.If the battery shows 12 volt then its confirmed that battery is good.But what about the battery connections,if the fully charged battery is not connected properly or its connecting terminals have got co-rodded or dirty or loose then this can be the cause.Remove the battery connections and reconnect it to their respective place.Then check.Also if the starter is faulty then it will not let the car to start,so get the starter checked.The starter gets power from battery to start the car. If the starter is faulty then it will not let the car to start. In many cases will be due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or crank sensor. Also this problems are related to faulty spark plug. Check the spark at spark plugs when you start the car. Do you notice any spark. Actually you should see. If in case there is no spark then it's a spark plug problem. Also the coil pack gives power to spark plug. So check the voltage at coil pack. It will show 12 volt.If there is no voltage noticed at coil pack then its faulty coil pack that has to be replaced.Also check and confirm that there is fuel in the car. If its very low fuel then in some cases this causes the problem. Also check and confirm that fuel pump is functioning properly and the fuel filter is not clogged. One of the easiest ways to check for a fuel pump related problem is to spray a little starting fluid into the air intake while trying to start the car. If the car starts momentarily, then there's a good chance the fuel pump is not working or the car is out of gas. You can also listen for the fuel pump's humming sound when the key is first turned on. Also if a inoperative fuel pump is suspected, a good technician will always check to verify there is power and ground being supplied to the pump, to eliminate the possibility of a bad relay or electrical issue. Fuel pressure can be checked with a pressure gauge and if there is pressure, pulse can be checked at the fuel injectors in several ways including the most common, with the use of noid lights. If the injectors don't have pulse the engine won't start. ---------- This troubleshooting tips will help you to solve the problem.Thanks.Helpmech.

The Battery could be shorting out internally and that was the reason your Alternator broke. It will happen again to the Rebuilt Alternator if the Battery is not checked or replaced.

When you get the car driveable, take it to Autozone or Oreillys for a Starter Draw test. This can be the short that killed the other Alternator.

My '93 F250 5.8 l Automatic was turning over slowly when cranking to start. Replaced battery no change; Then after sitting for 2 mo. turning key to start produced only a click and dead gauges (battery...


The battery to starter connection has power.the battery is ok.but there are many other possibilities related to battery and its other connections,the spark plugs,the fuel pump,the fuel itself,the sensors(o2 sensor,maf sensor)the valve(IAC valve,egr valve). Most probably the spark plug,the coil pack and crank shaft sensor.This 3 are not getting power to get the car start.

There are some possibilities which you will have to check in this case:--

1) First of all check the power and voltage to the battery. With meter it will show exact 12 volt if the battery is charged. If the voltage is less get the battery charged at local auto repair shop. If the battery is internally drained and not getting charged then its time to replace the battery.

2) When you crank the car do you see spark coming at the spark plug? If no then its time to check the spark plugs and coil pack. If the spark plugs are not worn out and looks new then its time to check coil pack. The spark plug gets power to spark from coil pack.

3) The other thing to check in this case is the starter solenoid of the car. If the battery is charged and you start the car then it gives power to the starter to start the car. But if starter is faulty or not connected properly then car will not start.

4) The other thing to check in this case is fuel in the car. If there is fuel in the car then check the blockages in the fuel pump if the fuel pump looks proper then check the fuel filter above the fuel pump.

5) If all the above possibilities mentioned above checked out OK/perfect then it's a electrical issue and the wiring's in the car needs to be checked. The car gets power from the battery to get started. so the wires from battery needs to be checked one by one.

Changed starter and alternator and still wont start on 1988 grand am


There are few things that you will have to check. 1) Is the battery properly charged. 2) Are you getting spark at the spark plugs, when you crank the car to start. 3) Is there proper fuel in the car. ---------------- If the battery is not charged properly the car will not start.Check the voltage of the battery .It should be exact 12volt. If there is no spark coming when you crank the engine then its the problem of either the spark plugs or the coil pack.the spark plugs gets power to spark from coil packs.Also check the fuel pump and fuel filter.If the fuel pump and fuel filter are worn out then it will not supply the fuel properly to the engine and this results in no-start problem. If all battery, fuel pump and spark plugs checked out OK then its time to check the wiring connections between the battery to starter and battery to alternator.This will help.

I had the starter fixed in my 1996 Jetta,, but it wont go back in.. whats the problem? The motor seemed to drop some , when I took out the starter,, now it just wont fit back in,


I'm assuming you have a standard transmission then, the starter mounts from the front of the engine its actually part of the front motor mount as well. When you took this out you should have had a jack stand under the engine block to support it during the starter removal. You will now have to lift the engine back to its proper position before attempting the starter reinstall. Be careful to put the three bolts back in the same place as they are different lengths and only go in one spot. May be a dumb sounding question but I have to ask it, did the place where you had the starter rebuilt give you the wrong starter ? ? I've had this happen to me before.
Good luck !

94 Firebird 3.4L starter and coil packs dontget power.


There are several issues that could be at work here but let's see if I can help provide a little information as I understand it for your model. Does the dash light up when you turn the key on? You don't indicate if the car has an automatic or manual transmission. Starting with the starter, you apparently have it properly wired including the main ground going to the cylinder block if you can get it to crank by shorting to the solenoid terminal on the starter. There is a yellow wire that comes off of the ignition switch and tees off and goes to a theft deterrent relay and also either a transmission range switch if you have an auto transmission or a clutch start switch if you have a manual. From either of the two switches the yellow wire (or could be brown at this point) then goes again to the theft deterrent relay. There is a purple wire that exits the relay and then goes to the solenoid terminal on the starter. Sorry, I don't know the location of the relay. If you can bypass the relay by connecting the yellow or brown wire to the purple wire and the vehicle then cranks by the ignition switch then the theft deterrent system is causing the problem.

The coil pack gets it's voltage from the #11 10 amp fuse in the under hood electrical center via a pink wire. That fuse will only have voltage when the key is in the on position. It also grounds at a connection with at least 5 other wires, on our 95 firebird it was on a thermostat housing bolt.

Just make sure you have all the ground wires connected and that all the connections are good. A simple test to check for a bad ground is to connect a test light to the ground terminal on the battery and touch the point of your test light to the engine or what ever component ground you want to test and try to power that circuit by either turning on the ignition switch or cranking the engine. If there is a bad ground, your test light will light up bright as it is trying to close the circuit instead of the proper ground path that it should be taking. This test will only be accurate though if you are using a common bulb type test light. Diode test lamps or other low impedence test lamps could give an innaccurate result.

Hope this helps. Just be carefull when shorting starters so you don't have any accidents.
