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.

Why does it turn over but won't start?


You need 3 basic things to make an engine run. 1 Compression, 2 Fuel, 3 Spark. So start buy checking for spark, remove a spark plug and plug it back into the wire. Now touch the threads of the spark plug to metal ( a good ground on the engine) and then turn the engine over (try to start it) and see if you have spark? No spark find the problem. If you have spark now see if you have fuel getting to the engine. You can try pouring a little fuel into the carb or throttle body and then see if the engine will fire or try to run. If it tries to run or fires you have a fuel problem. You need to find out why it is not getting fuel. Spark or fuel, 90% of the time are the main causes when an engine will not run. I hope this gets you started. Rod

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.

It was sputtering from time to time... Had to give it a little gas this morning to get it to turn over... Came back from work...wont start cranking fine... just wont turn over 91 lebaron


well first off you want to make sure your getting fuel and if you are getting fuel then check the pressure to make sure it is were it should be you can rent them from autozone for free it got a deposit but you get it back when you return it . if fuel is good check your spark pull out spark plug have someone try to start car look at the plug if you have bright blue spark in all your plugs spark is fine if orangeish color spark change ignition rotor and distibutor cap and wires you might as well do it all if spark and gas are both good

check crankshaft postion sensor as hard starts and on most cars if there bad they wont start also check camshaft position sensor they both tell your cars pc when to fire spark and to what cylinder to fire it to

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.
