I have 1996 Discovery, new spark plugs and plug wires, new fuel pump. However I began having starting problems a few weeks ago, now it won't start at all, it turns over though. I don't think there is a spark at the plugs. any suggestions?..ignition coil? | ||

Do you have an OBD II code reader? | ||

have you checked fuel filter? | ||

When I don't think I have any spark, I do not check the fuel filter, I check the ignition. Let's get back to the basics, we need fuel, spark, and compression. Is there fuel at the fuel rail? Does this truck have the schrader valve on the rail? If so, is there fuel there? If yes, go to next line. If no, is the fuel pump running? If no, is there electricity to the pump? If yes, pump fried, if no, start tracing circuit-fuse? Relay? If there is fuel to the rail, pull the coil wire, hold it near something grounded and crank (yes, I know the manual says not to do this, but the truck don't run anyways). Do we have spark? If no, why? Hold up, it's a '96, they don't have separate coils do they? I thought they had coil packs. Is this an NADA vehicle? ROW vehicles sometimes had distributors on this MY truck... Peace, Paul | ||

Thanks for the help Paul, I'll check all that out and see what happens. Lates, Stephen | ||

Thats what my dad always said Paul, FUEL, FIRE, COMPRESSION.  Just becomes a little harder to troubleshoot with a computer.. we were always working on forklifts with flat head continentals. -leo | ||

Funny how things our fathers told us about still have validity. My old man used to wrench 1930 Harleys, and I doubt he's turned a wrench in anger since. I used to work for a guy (was apprencticed to him in an A&P position). He used to say it suck, squeeze, bang, blow! I am forever amazed at hom often some folks (actually, one in particular, but I consider him to be a friend) will instantly jump up and say it can't be fixed without a Test book, when in most cases, it is something far more fundamental. I'm not saying that this might not be the fuel filter, nor am I blanketly saying the OBDII reader would have directed this gentleman to hisprobem, but these are all tools we use. And, as I am not there, but sitting in front of a keyboard, it is as though I have both hands and half my brain tied behind my back (with apologies to El Rushbo). In spite of these limitations, or perhaps because of them, it is very pleasing when we can solve one of our brother's problems over the itnernet-thanx Al! Peace, Paul | ||

Starting problems are often caused by leak back in the fuel system over night due doggy fuel pressure regulator. The most common no spark fault I if all the simple stuff is ok is the ignition amp module on the distributor | ||

Shaun: Most '96 Discos (NAS) have no distributor. I'm considering swapping a regulator tomorrow-if it doesn't rain and I can finish other trucks first. But, fuel pressure can also fall and result in a flooded condition due to leaking injectors. | ||

Crank position sensor, worth a check if your truck has one. | ||

Does a 95 Discovery have a crank position sensor if it does were is located? Just like to know. | ||

Guys The USA cars must be different to the Australian ones, down here they have distributors well past 96. We don't have the same smog laws. Discos fall through a loop hole in the local laws due to the fact that they are considered to be lite trucks. My car doen't even have cats in the exhaust. Here they just have 14 cux basic injection and that is all they need to meet the smog laws that apply to them. I suspect our cars might go a bit harder as a result as well. They are certainly easy to fault find. | ||

I suspected you might be in Oz Shaun! Hope I didn't come off as impolite. Marlin: The crank position sensor is a component of the distributorless ignition systems found on Rovers in the US and much of ROW post -95. | ||

Paul don't worry I'm not, I figured your cars are different. Because of our lite truck laws our cars get off pretty lightly when it comes to smog control. Like I said my car doen't even have to have cats fitted, To get them to pass emmissions they just retarded the static spark timing and fit tamper proof covers to air flow meter and base idle setting adjusters. As a result I think Australia is where Landrover gets rid of all the left over bitts. As long as they made 1% co at idle they they got through the laws and it never really gets checked again by any Government Dept so you can kind of do what you like. This in mind a tweak on the timing and airflow meter improves the fuel consumption and power and know one cares. |
