Fuel pump is bad or plugged fuel filter it seems. Crack the line from the filter leading towards the engine first. If gas starts squirting out fast, you have good pressue. If not the filter is plugged or a bad pump. How old is the fuel filter by chance? If original its plugged up by now

Have you tried using a mallet and tapping the fuel tank? Don't beat the **** out of it, but try a few smart blows.

94 jeep grand cherokee was running great got up the next morning to find its not firing anymore what couldve happened


why not answer simple questions first?
how many miles ? on this car?
no engine stated 4L or 5.2L???????????????????????
I guess you are working with no scan tool.?
NO voltmeter
I see now the only fact we have is the single
outside, spark coil is dead. 1 fact.
if its good (simple tests, ohm out the primary and secondary yet>?)
so that means the ECU is cutting spark
In fact I bet the ASD relay is not energizing
or is dropping out while cranking.
if the ASD drops, spark ends, a fact.
if the ASD drops you must scan it or use the key jive test (key on 3 times)
If the ASD drops do not buy a new PCM

the ASD drops for many reasons up to 8.
including VTSS errors. (yup)

1: ckp dead.
2: cmp dead
3: TPS pin 2, throttle angle at 100% or near 5v.
new 1volt is correct , foot off gas pedal.
4: If PCM see's spark is dead, it cuts fuel.with ASD
the ASD logic uses a 3 second rule.
all the above, must be good or it drops
when it drops vast things go off line,
fuel, and spark and more. its for crash protection
no crash and burn as seen on TV, and USA law.


questions
did you pull out the CKP ,with 1 bolt type, and slotted hole?
oops
did you pull out the distributor then not prevent loss of injector timing, oops2.
IS the cluster warning lamp on "SECURITY"
oops VTSS is un happy if yes, it can be bypassed

My xj8 Jaguar crank up and sets right back off what all could be wrong


Security is set. Could be one problem. Fuel system can do this, but rarely. Takes a scanner to see where to look first.

Engine turns over but won't start


Start with testing the coil. Disconnect the wire and have someone crank the engine to check for spark. The spark should jump about 1/4 inch. If spark is good, suspect fuel problem. Spray some ether into the intake while the engine is cranked. If it starts and then stops, it is a fuel problem. Your battery is probably going to go dead with all this cranking, so keep a charger on it. Also give your starter time to cool between long cranking.

Cranks but wont start


Likely a fuel delivery problem.

Check the filter, as it may be clogged and due for replacement. To test for fuel delivery, open your airbox and spray some starter fluid (purified ether, usually) down into the throttle body while someone else cranks the engine. If it fires up and runs for a few seconds but won't run without spraying the starter fluid, then you know you've got spark and compression. If that's the case, there could be any number of potential issues: throttle position sensor (not very common, but it does happen), fuel injectors clogged (common if you use low-grade fuel), fuel filter/strainer clogged (filters should be replaced every 30k miles or so, on average), fuel pump failure (you should hear a buzzing from the fuel pump when you crank the engine).

If the starter fluid doesn't help, then the problem is no spark. Check each plug/cable for fouling.

Car will crank but will not start. New battery and new starter installed. Gas line to carb. has gas and all 4 plugs have spark.


If you have spark, compression, and fuel, it should start.
Have you checked the compression or do you know for sure the timing belt is ok ?
Are the spark plugs wet or dry ?

Jaguar XJ6 1993 not starting.


I have had a similar problem and found that the centre wire from coil to distributor cap had slipped back just far enough from inside the coil to not make a good connection..and no spark meant cranking but no spark to plugs...
