Give the battery a full charge....un clip the air filter housing and leave it resting in place, put your foot to the floor on the gas pedal and keep cranking til it starts up,dont release the ignition key til it fires up,it will pop and bang and then when it fires up will smoke for a little bit (couple of mins) and then it will be fine.
If that doesnt work you will have to remove all 8 plugs,clean them,pour about 2 teaspoons in each cylinder before replacing plugs then do the same as above.
What happens with these engines is the cylinders get a bit too much fuel in them and it washes the oil away down the bores thus losing comression so it wont start.Instead of starting it up and switching it off briefly,let it run a bit and then give it a little rev before switching off...hope this helps

My 92 jeep cherokee sport won't start getting fire and gas and has a slight back fire when turning over changed cranking sensor but still will not start what else could cause this?


old old jeeps..... which engine, the 4.0L inline 6? why not say ?
well here are the proper linear steps.
1: fuses good battery charged, and cranks robustly.
2: compression over 150psi, WOT. if not fix that. ?
3: spark strong to all cylinders not just 1.?
4: spark timing check show its still firing near 0 TDC.
5: at the point in time, it will run on test fuel for at least 3 seconds.
does it, feel better now? that you can see it run?
if not the CAT may be melted and blocking engine exhaust 100%
6; and last is fueling (the ECU cuts fuel or 3 reasons, )
dead cam/crank sensors, or dead tacho line.
7: ok check fuel pressure next.

i skipped the all important scantool because we dont have one
1988 to 92.. (not until 1993 do they work OTC tools)

did you do the magic key on off test>/
?
keyon 3 times, might work on latter 92s.....

the crank sensor is tricky to replace.
its not just jammed in a hole.
did you read the FSM Book first. before touching it.
some have a paper sticky tape on the end (jeeps do)
and when you start car first time, the tape flies off getting that critical gap correct. (pure magic no?)
if not done right, you now have 2 problems.... not good that.

Jaguar xj sport 3.2 no spark or injector pulse


If ECU has crank signal and engine turns over, ECU should give injectors a pulse and trigger the ignition. If not ECU might be bad. You should check power and grounds going to ECU. There are usually multiple power and grounds going into ECU

2001 jag stye turns over but won't start what could be the problem?


It could be as simple as a bad fuel pump or clogged fuel filter to something more in depth like a broken timing chain or bad sensors. Check the Fuses first to make sure they are all good then check the relays under the hood. If the fuses are good and the relays then spray some starting fluid into the air intake, If it fires then the problem is a fuel pump or filter if it doesn't you are going to have to test the Crank and cam position sensors to find the bad on and the coil pack.

Hi my jag xjr 4lrt wont start it has fuel supply it has a sprak it turns over but will not start any ideas ive been told it may be the imobiliser


It takes three things to make an engine run. Fuel, spark and air. If you have fuel and spark at the cylinder, there's no reason it should not start. One or the other is missing. The only way to tell if the fuel and spark are reaching the cylinder is to pull a spark plug. Try to start the engine then pull a plug. If you are getting fuel, the spark plug will be wet and smell of gasoline. If it's dry, no fuel is reaching the cylinder. Put the plug wire back on the spark plug and lay the plug down where you can observe it while cranking the starter. If you are getting spark, yo will see the voltage arc across the tip of the spark plug. Perform this test and find out which one is missing and then you can trace down the problem.

My 2001 Montero Sport (NOT 4WD) will not start. I suspect the fuel pump has gone bad. How can I be sure? The engine turns over and the spark plugs ARE firing. I also suspect it may be an electrical issue...


You can get a spray can of carb cleaner and spray a little in the intake. If it starts, then your problem is definitely fuel - related. It could be a number of things if it is fuel related, but the fuel pump is the most common cause. The only way to know for sure is to check the fuel pressure at the fuel rail then check to make sure the computer is firing the injectors. You should be able to hear the fuel pump run for a couple of seconds if you listen at the fuel tank while someone turns the ignition to the "Run" position. However, the fuel pump could be running and not putting out enough pressure to start the engine. If you can't hear it at all, then most likely, that is what your problem is. The second most likely cause if you can't hear the fuel pump is the security system may have the fuel disabled for one reason or another.

Just tried stating my jag 3.2 sport, started then dies, when tried to re-start it the tone appeared to change and the check engine light came on . 1995 n reg , i can smell fuel in engine bay, any...


Check the HT leads for security, make sure the battery is fully charged, clean the sparkplugs and try again, could just be a loose cable for starters.
If this doesn't solve the problem you need to have the engine diagnostics run at a garage before any advice is possible - even if you check for spark and find none you cant suspect the coils until you know the condition of the ECU.

Won't turn over


your starter is shot most likely. the noise is the drive gear at the end of the starter not throwing far enough onto the flywheel. Dont keep starting like this as a new flywheeel will be v expensive if damaged! Have your battery checked out too as a limp battery will not produce the power that the solenoid needs to throw that gear out properly and a new starter will fail too.
Pls rate me if this helps.
