1999 range rover 4.6she starter keeps running

I'm assuming just by the fact you had a new battery and new starter that sometimes when you turn the key to the start position , nothing happens . Is your vehicle a automatic transmission ? When it doesn't start have checked for battery voltage at the starter solenoid S terminal ? Is there B+ voltage at pins 30 & 86 for the starter relay ? Pin 86 while cranking the engine or trying to crank the engine over . Pin 30 check with key on . Try moving gear selector to neutral . Videos on youtube for basic automotive electrical testing .

Starting System Circuit Description
Voltage is applied at all times to the ignition switch from the IGN A fuse 6 through CKT 242 (RED). When the ignition switch is turned to the START position, voltage is applied to the CRANK fuse 8 through CKT 5 (YEL). From the CRANK fuse 8, voltage is either applied to the clutch pedal position switch (M/T) or the transmission range switch (A/T) through CKT 806 (PPL). When either the clutch is disengaged (M/T) or the transmission is in park or neutral (A/T), voltage is applied to the coil of the starter relay through CKT 1035 (PPL/WHT). Since the starter relay is permanently grounded at ground G105 through CKT 150 (BLK), the starter relay energizes.
Voltage is applied at all times to the starter relay contacts from IGN A fuse 6 through CKT 242 (RED). When the starter relay energizes, the starter relay contacts close, and voltage is applied to the starter motor solenoid. Since the starter motor solenoid is permanently case grounded, the starter motor solenoid will energize two coils. The pull-in winding coil energizes in order to pull the starter motor solenoid contacts closed. When the contacts close, a plunger on the contacts causes the pull-in winding coil circuit to open. The hold-in winding coil then holds the starter motor solenoid contacts closed. Voltage is then applied to the starter motor from the battery through CKT 1 (BLK) and the closed contacts of the starter motor solenoid. Since the starter motor is also permanently case grounded, the starter motor will run until the ignition switch is moved out of the START position. When this happens, a spring in the starter motor solenoid moves the starter motor solenoid contacts and the plunger back to the rest position.

i would think this is an ignition switch problem if starter spins when ign key removed, the ign switch isn't cutting power to the starter circuit ,remove the steering column cowling panels and check for loose wires etc , with a voltmeter find the cranking wire , only comes live when key turned to starting position and should give no power when key returned to normal position , i suspect it is internal to the switch , you could try spraying wd40 into the switch barrel in case there is a sticking part otherwise a new ign switch will be required good luck ,keep me posted if you wish

I would suspect that the solenoid contacts need replacing as they may be burning together. Pull the starter and have an accredited auto electrician bench test it.

May have melted the fusible link going to the starter. Or blown the main fuse. I dont know the exact location of the fusible link in this truck. What happened is the starter solenoid wire completed it's path to ground without first going thru the solenoid windings.

why you have replaced the Fuel pump? who advised you to do so?
be guided as follow 1. on the Engine Side on the top there is a fuel rail for the injectors. turn the ign. key to the second position (on) and check the valve located on the fuel rail if fuel is coming pressurized and still won't work. then open on of the spark plugs wires and check if spark is there. (Be Careful doing that). if no spark then is there any message comes up on the Dash? if not messages then you can check the Crank Sensor if no current being generated from the ign. coils.

Does the engine turn over with the starter,and just will not run?Or does the starter not turn the engine over?

if the pump has run for over 15mins it will go eas
if you unplug ecu [ bottom one under pasenger seat] do not have key in or enging running it may reset if this is a no go it will have to be plugged in and reset
yours dave

the unit where u put the key is broken on the back side of the unit is a swith that is y u can turn key in positions ....if there is a time damage often similar problems comming...

need to run codes from obd

hi if you just try this suggestion and update back on result ?? if you pull off the small/thin wire that connects to starter solenoid then with a seperate length of wire connect one end to the solenoid where you have taken the other wire from use a terminal or crock clip if possible ? then turn on ignition ensure gear in neutral! NOW touch firmly but only for a seond or so ! if starter turns over ?engine starts? then the problem you have is possibly? the key start circuit from ign/switch ? or may be the ign key req's re chip this test will bypass the key start and immob if starter turns ? hope this brings the reason for fault towards a conclusion ??
