My 95 discovery is not running again. Was running fine all day until I replace the distributor cap. Went to start it and the engine was just turning no start. All the wires are on right, so I thought it was the cap so I put the old one back on still the same. Check engine light is not on and no codes are showing up. I also had a hotstart problem, would not start after it got hot, but today it started up every time until I replace the distributor cap. Any ideas anyone!!! | ||

Did you also replace the rotor? If so - check that. Is the contact between the top of the rotor and the "button" in the underside of the cap good - make sure the button is in there - I've seen them disappear. Also- did you smear the bit of conductive grease on the top of the rotor (where it contacts the button on the underside of the cap)? Double check that you have refit the wires to the cap in the correct order. Bill | ||

Sounds pretty obvious, but did you wire the distributor cap for the correct rotation? ie: not completely backwards? | ||

Happen to me once. When i changed the the wire i forgot the firing order on the cap. And the truck cranks but would not start. Check the firing order on the cap. | ||

Well I mark the old cap so I wouldn't get mix up, so all the wires are on right. The distributor cap was the only thing I replace did not bother the rotor | ||

my experience tells me that i have to replace the rotor whenever i mess with the cap or wires. did you ever get your rig started? | ||

Check the coil, if your car turns but it does not start you might have damaged the coil!!!! | ||
| Marlin Begay (M_begay8) New Member Username: M_begay8 Post Number: 35 Registered: 03-2003 |
The rotor is new and was replace a while back, I also tried the coil in a different vehicle and it started. No luck in getting it started. | ||

Since you have a '95 you should have a timing light? Or spend $40 and buy one? Then do the old-fashioned search for spark, fuel, air. Since you fiddled with the spark side, hook your timing light to the coil wire. Crank engine. If your timing light flashes nicely you're getting juice down the coil wire. If not, you need a new coil wire or coil. Try replacing the coil wire. However, if your distributor cap/rotor is bad you won't get spark at the coil wire either (no path for the electricity to flow). In the olden days you could ground the coil wire to the chassis, then crank and check the timing light on the coil wire (the electricity would flow through the coil wire to the chassis). I don't know if the the 95 Disco coil will be happy being tested in this manner. Maybe wiser heads could help out here? If your coil wire flashes, then try all the plug wires to see if they're getting spark. If no spark to any, you need to replace your distributor and rotor. If you still don't have spark after replacing distributor and rotor, try replacing the wires. If you still don't, you have a Great Mystery! If you are getting spark to all cylinders and the engine won't turn over, it's time to move on to checking the fuel or air systems. I don't know how to troubleshoot those bad boys, maybe someone else can jump in? But check for spark first! (since that's the only thing you fiddled with) | ||

Well I am getting spark, but no start. The plugs, wires, and rotor are new this all happen when I change the cap. I tried the old wires and the old cap is on and still no start. I also check the fuel pressure and it was okay. | ||
| p (Pfb) New Member Username: Pfb Post Number: 22 Registered: 08-2003 |
I know you are "sure" the wires are on correctly, but check them again. Ensure that firing order, #1 tower, and rotation direction are correct. If you've checked everything else and it still won't fire, it's time to recheck the things you are positive are not the problem... | ||

We are having this problem as we speak. Same year.Changed rotor wires and cap. wont start. Did anyone figure out the problem? | ||

Maybe you need to reset the ECU. The manual always has you disconnect the negative from the battery when you do any work. Would'nt this reset the ECU? I know it may be a strech,but with spark, fuel pressure etc. The only thing left is compression and that's not likely. I had this problem on a differen't car (VW BUG) and the issue was compression (the heads came loose). Check your plugs make sure they are seated properly. Thats my 2 cents. | ||

I will try it. I have gone over wires and everything. | ||
| charles pastrano (Charles) Senior Member Username: Charles Post Number: 296 Registered: 08-2002 |
No dice any other ideas? | ||

does it do anything even try to turn over? | ||
| Joey (Joey4420) Member Username: Joey4420 Post Number: 173 Registered: 04-2003 |
Are you getting fuel? Since you have checked just about everything for spark, I would look at fuel issues. I would also look at the Reset switch under the hood just to make sure that this is not an issue. | ||
| charles pastrano (Charles) Senior Member Username: Charles Post Number: 297 Registered: 08-2002 |
Are you refering to the fuel cut off? | ||
| Phillip Perkinson (Rover4x4) Senior Member Username: Rover4x4 Post Number: 422 Registered: 02-2003 |
I think its the inertia switch as I have heard it called before. When you turn the key can you hear the fuel pump at work? | ||
| Marlin Begay (M_begay8) New Member Username: M_begay8 Post Number: 37 Registered: 03-2003 |
I hear the fuel pump come on when I turn the key, I'm thinking I might have a weak spark, but I tried the coil in a different vehicle and it started. I might try to jump start it to see if it works. | ||

One thing I just remembered, what about the ignition amplifier. It may need to be replaced or it's connection may have come loose. | ||
| Marlin Begay (M_begay8) New Member Username: M_begay8 Post Number: 38 Registered: 03-2003 |
The ignition amplifier is fairly new, I also check the connections which was okay. I mounted the amplifier on the air filter box along with the coil a while back but that gave no problems, could that have something to do with it. | ||

Do you have the factory manual? If not I can send the factory test procedures to you. | ||
| Marlin Begay (M_begay8) New Member Username: M_begay8 Post Number: 39 Registered: 03-2003 |
I have the haynes manual which good but not that detail. Could you send the test procedures. Maybe it might help. | ||
| JVelocet (Vracer) New Member Username: Vracer Post Number: 28 Registered: 06-2003 |
Marlin, you have some mail | ||
| Marlin Begay (M_begay8) New Member Username: M_begay8 Post Number: 40 Registered: 03-2003 |
Thanks for the info. I will see what I can find out. | ||
| Marlin Begay (M_begay8) Member Username: M_begay8 Post Number: 43 Registered: 03-2003 |
Well today I went to check the voltages, and I found out that the coil has 12 volts on both the pos.(+)and neg.(-) side when the key is turn on. My dad said I have a short somewhere. But where? Anybody have ideas what could cause this short. | ||

Update Our problem was with the rotor and gear. When the rotor was pulled off we didnt hold down the sproket under it. Doing this made the springs on the inside come apart. |
