Cranking but no spark - Land Rover Cars & Trucks

NO YEAR TOLD 2000?
THE POST IS NOT CLEAR AT ALL

• STARTER MOTOR DEAD AND WILL NOT CRANK.
• CRANKS FAST BUT WILL NOT START

NO VIN OR COUNTRY TOLD TO THE BLIND.

DID YOU MEAN CRANKS OK BUT WILL NOT START?
OR?
NO CRANK HAS 6 CAUSES
NO ENGINE RUN HAS 50
LEARN TO BE CLEAR WHAT WORKS AND DOES WORK'
BOTH.
IF CRANKS ONE OF 2 THING STOP STARTING
IMMO LAMP ON DASH NOT HAPPY

1. ENGINE CAM BELT FAILED.
2. SPARK DEAD SCAN IT TO SEE WHY.
3. FUEL DEAD. THE ECU CUTS FUEL IF IT SEES SPARK DEAD.

USE A SCAN TOOL TO SEE WHY THE ECU/ECM/PCM
WILL NOT CREATE SPARK, GUE$$ING IS NOT CHEAP.
WE USE TOOLS TO FIX CARS OR GO BROKE

fuses good< oops
scan the PCM see errors cranking OMG it tells you why:? sure can.
forgot the 6 new spark wire plug set, replaced 1 by one never all at once, 6 new OEM type spark plugs and gaped correctly
22 year old spark parts are no good ever.
test for spark on all 6 yet, spark is 1st or there can be no FIRE.

4.3L cranks but will not start and run and stay running.(problem1)
fire cant be seen, but spark can.
1,2,3 engine,spark, fuel good 1,2,3 in that order
spark and fuel can not run a dead engine, so 1 is first engine'
compression good 150psi up not lower, all near same
next is spark if EFI sees spark
actual fuel pressure not told just OKay. pressures matter big time in EFI, and at cranking for sure. then idle and WOT later.
engine is free running so all tests are safe, cranking too.
the service manual covers all fuel checks cranked, balance test and leak down tests.

If your doing a lot of cranking and testing, You need to hook up battery charger or use jumper cables to see if spark comes back. Make sure the battery has a full charge and connections all good. Even if battery is only down a couple of tenths, it might make a difference. 12.6 volts is the generic spec for a full charge. I have seen starter motor taking all the voltage, not much if anything left for ignition system. Could be other issues?

if it cant crank there is no spark , there will never be fueling.
The starter is first. does it crank over the crank shaft fast.
yes, i must guess.
then next is spark, with no spark , EFI cuts fuel. (no fires)
so if it cranks the crank shaft fast (look) then check spark now.
on all cylinders not just 1.
then post. results for step 3.

Yes you are heading in right right direction. Check to see if there is spark out of coil. Spark at coil means replace distributor or rotor. No spark at coil replace ignition module or crank sensor good luck. Oh yea crank sensor is cheaper i would try that first if there is spark out of coil.

First you must check to see if engine is mechanical sound by performing a compression test. remove the spark plugs install a compression gauge in the spark plug hole and crank engine about 4 cycles compare readings to all cylinders reading should be around 125-150 psi readings in the 50 psi range possible jumped or broken timing belt. If engine is mechanically sound test for spark at the spark plugs use a spark plug laid against valve cover and have some one crank it over look for the spark to jump the gap. A no spark problem is internal in the distributor.

I am a self emplyed mechanic, if a motor cranks but does not start, that is not a starter, you need to see if you have gas or spark . is there a buzzing in the gas tank when you turn the key. if so then you have gas. now you needto see if you have spark. need 2 people to do this . pull a spark plug wire and stick a screw drive in the boot and crank the motor please stand back,and look for spark. if you have spark. then you need a crank position sensor thank you ted

Yes. No crank sensor signal usually means no spark. The ecu has to receive crank position to set spark timing. I think you've really hit a big problem. You may need to get in touch with some people who have done this mod. I've always heard it's best and easiest to swap the engine with its ecu and the wiring harness into another car. Or something more compatible with that jdm engine.

check for spark and then check for fuel

if it cranks but wont start check for spark by sticking sparkplug in end of wire rest on block have someone crank if there is spark it is a fuel pump issue if no spark check crank sensor
