Starts fine when cold, after running dies on idle then wont start

I had this same problem my 1996 discovery . oddly enough lights came on bright etc i thought ok all electrical is good .. Nope , i jumped a pair of battery cables from the negative battery post to the bracket where alternator bolts on to a ground pretty much .. This problem went away completely.. So it was just a current issue wasnt getting enough to light those spark plugs my guess or the computer was doing something else whne it diditn see all the current it needed .. i have no idea but it fixed it

The ignition system is controlled by the ECM. Check power at fuse box in on right side under dash. Check fuses right side engine compartmentlower dash panel if all OK check power to ECM located right side "A" pillar in alloy box. this unit could be faulty if no spark at coils, assuming they have been connected correctly. may have to get tested for codes at L/R dealer or someone with test tool. Another source of problem may well be flat battery in transponder key. The indicator light on the dash willflash rapidly for 10 seconds if the vehicle has been unlocked with the remote and the drivers door is opened if the battery in remote is getting low

Sounds like the crank position sensor

check the distributor advance unit pull the pipe off and then **** on advance unit to see if the diaphragm moves and stays in ,because the membrane goes then it will not start ,so you advance the distributor and it will start ,but once it gets hot the engine will not start unless you ****** the timing that bit .then when you do that it will not start when cold .

BAD spark! check plugs wires and coil packs. the wires are a real pain to replace because of the location of the coil packs between the intake manifold and firewall.

crank position sensor

tune up, fuel filter, air filter, dirty throttle body, put good one to gas fuel injector cleaner.

hello mrs melissa well i got the same car . and 1st it used to do the same with me i change the fuel pump and the plugs and then it still the same. but what i did i change the elic cup and now it's runing fine and so power full !

hi Mattperez831.
this is all i could find out from the internet.
check.
crank sensor,Fuel pump, ignition coil is getting hot,.
A "main" relay can control multiple circuits, primarily for the ignition..
advise to him was to change the ignition module..
coil pack..
