Question about 1989 Jaguar XJ6

1 Answer

89 Jaguar XJ6 engine not turning over

I just got my fuel filter changed by PepBoys and I added the Chevron Plus Complete Fuel System Cleaner into a tank of gas. However, yesterday when I was reverse parking it into a parking space, it just all of a sudden stop running. I turned off the ignition and tried to turn it back on, but the engine would not turn over. I waited about 2 hours and it started right up. I then drove it to Chevron and filled up the tank more than half, but soon after when I turned on the ignition, the engine would not turn over. AAA then towed me to PepBoys and as soon as they lowered my car, I turned on the ignition and the engine instantly turned over. What could be wrong with my Jaguar because PepBoys told me they couldn't diagnose it?

It could be an ignition switch,when it happens try wiggling the key while holding it in start position. also is there a clicking, or a clunk sound when problem arises, if there is then the starter solenoid is bad (most starters have the solenoid mounted right on it) so replace starter if you here a click/clunk noise w/starting

    the crank sensor does not control the cranking of engine. it tells the computer that the engine is cranking.

    there is a difference between turning over(cranking) and engine running (firing) when you said originally it wasn't turning over you should have said it wasn't firing. i guess if you don't know whats actually happening you can't be expected to explain it the right way.

Change your fuel filter. Running the tank empty will pull any sediment that has accumulated in the bottom of the tank into the fuel system. There is a good chance your filter is clogged and not letting enough fuel to the engine.

could be a few things - first, when was the last time your fuel filter was changed - inexpensive fix around $10 for parts and 30 minutes labor - secondly, last time spark plus or wires(boots) were changed - these have an average lifespan of 50-100,000 miles depending on your driving - also a fairly inexpensive fix $30-$100 depending on plug type and wires/boots - lastly, is the SES (service engine soon ) light on your dash - if yes - have the codes read at a local auto parts store and determine if any engine emissions parts need to be replaced (idle air control, throttle position, EGR valve, etc - and finally, there could be gunk and debris in your fuel tank clogging the pump and fuel strainer - throw in a large can of Chevron Techron fuel system cleaner with a full tank of premium fuel the next time you fill up - hope these help

My 98 Nissan Maxima was hooked up to a emissions machine and it said I had a bad knock sensor, which i heard was a common problem. It also said that cylinder number 5 was misfiring. i just got a tune up...

Did you change the fuel filter. The fuel additive you used will not get the water out of an old fuel filter. Excessive water in the fuel could cause the misfire. The Maxima is probably due for timing belt due to age. Missing teeth on the timing belt will result in timing walk. The knock sensor is probably getting pre ignition signals. Look at the belt and get the fuel clean and go from there. (Do an OBDII Scan)

I have a 1998 Corvette with 42k miles. Recently the fuel gage will drop to empty after filling the tank and driving for about a half hour??.. Is the a Fuel gage Fuel Pump, Fuel filter Problem?...

I had the same problem with my 98 Corvette with 69K miles. Mine did exactly as you described soon after I purchased it in November of this year. I went online and read posts of others with the same problem and how to try and fix it. At 1/4 tank add 2 bottles of Chevron Techron cleaner and fill up with good name brand premium fuel. The Techron cleaner will clean the sulfur residue and other contaminants off of the fuel level senors in each of the left and right hand side gas tanks (C-5's have two gas tanks on either side connected by a transfer pump with each side having it's own fuel level sensor). I did this and so far after nearly 3 tankfuls there's been no recurrence of the problem. However, if this doesn't help then the alternative is to replace some if not all of the components mentioned earlier. I got a $1300+ repair quote from my favorite garage prior to applying the above fix. I'm no mechanic and I may have some of the actual part names incorrect. I hope this helps you out and fixes your problem! BTW, you can also use a full can of SeaFoam cleaner in lieu of the Chevron Techron cleaner. I used the two bottles of Chevron Techron the first tankful and used SeaFoam in the second tankful. I plan to use a bottle of SeaFoam every 3-5K miles to help keep this problem at bay and keep my fuel system cleaner!

Draining fuel from 2004 crysler seabring.

Just go buy some fuel stabilizer and top off the tank and drive. Two years isnt that bad. Then on the next tank use some injector cleaner. I like chevron techron fuel injector cleaner added to a full tank of prem 91. This is just a prevenitve measure to clean any varnish that may accumulated on the injector nozzles.
Then use 87 octane if thats what you normally use.

Draining the fuel system of a 95 ford taurus

Why. You will find the fluids hold up very well except gas which will evaporate off the light ends and make it hard to start. I would just add some Chevron fuel injector cleaner to the fuel tank & add a fresh tank of gas to whats in there.

Fuel Filter Changed

What happens when you remove air intake from throttle body & spray a little wd-40 in to the throttle body, and try to start? If it starts and runs temporarily, you've still got a fuel delivery problem.That coffee color worries me, like maybe your fuel lines etc are plugging up with rust etc, from inside tank. Have you added any fuel system cleaner to gas lately?
