Car will not start will crank but wont start I change coil recently because of the same problem but shortly after did the same problem

Crank shaft position sensor , B+ voltage to the coil , coil . videos on youtube .

could be a problem with engine electrical or still with fuel delivery. unhook a fuel injector line while it cranks and see if it shoots out spurts gas, just as the fuel pump line is supposed to shoot out a stream of gas while cranking. if you replaced the fuel pump, and no gas shoots out the disconnected fuel pump line, there is an electrical problem, (fuse, relay or wiring issue) to your new fuel pump. if the gas spurts out the loose injector line, then move on to electrical:

first ensure your ignition coil has spark by disconnecting the coil ouput lead and shorting it out to the chassis of the car. you should see a spark, when you short that circuit while cranking. if you have spark, you will have to move on to the spark plugs/ cables, then the distributor cap/coil packs.

if its part of the electrical system, it will be sensitive to temperature/humidity, and that may be why it only fails to start early in the morning. if it were the fuel injector, it would be more likely to start cold, and NOT re-start after it had already been warmed up and cut off recently.

Hi Delberta, The links below are short youtube videos showing how to fix a car that cranks but doesn't start, In the 1st video this guy tests if it's fuel or electrical.......................................................

I don't know if you have a cranksharft OR camsharft position sensor so here's both... I hope this helps...CHEERS.........................
Crankshaft Position Sensor car not starting coil spark

Camshaft Position Sensor P0340 Testing and Replacement HD

check for codes, if there is one it will help to know were to start diagnoses. it could be crank sensor. check for power and grounds at the coil and ignition module. just some place to start.

check that it has power at the coil ,crank sensor,etc. with a test light when cranking it over.

possibly a crack in rotor causing spark to go to earth thru rotor shaft shorting or grounding spark

If you have no spark try the ignition module, it controls the spark and if you don't have any and the coil is new its the only other option short of wiring or ecu!!

Really silly questions now!

If it is an auto box! have you got in any gear other than Park??
Have you checked the immobiliser????
Crank angle sensor is ok?????

I've experienced problems with Jag's in the past! this sounds crazy but check that the coolant temp sender is not worn out and shorting on the bonnet liner! sounds crazy but this has hapened before! shorted out the entire ignition system!

I CHANGE CAM AND CRANK SENSOR,FUEL PUMP,COMPUTER BRAIN BOX AND COIL PACK STILL GETTING NO FIRE UNLESS I JUMP A FIRE WIRE FROM BATTERY

check timing belt!! good luck!!
