Question about Jaguar Xj Series

1 Answer

I have spark to the plugs and I have fuel to the fuel rail. But the car does not want to fire off. I believe that there is some fuel getting to the cylinders but might not be enough. Checked to see if it was the coil but the spark plugs are firing nice and blue. Could this be a computer problem or the ignition amplifier or some other sensor problem?

1998 mazda 2500 cranks but wontr start, has fuel to fuel rail has compression has spark to the 2 cyls that were checked

If you have at least 40# of pressure to the rail, spark, compression, and the engine is in time...that only leaves one thing. Fuel injectors. I believe that the signal to fire the injectors comes form the crank sensor to the ECU

My engine turns over but doesnt fire up

Check and make sure you have fuel pressure at the fuel rail, Then make sure you have spark at the plugs. If you have both spark at the plugs and fuel pressure at the fuel rail I would look at the pick-up in the distributor.

Bmw 118d turns over but will not fire up we have had ecu tested and its fine any ideas??

check to see if you are getting fire to the plugs easy way to check is to pull a plug wire place a screw driver in the wire end that goes over the plug do not touch any metal with your hands hold it with the screw driver. have someone turn car over and hold metal end of screw driver to metal on car if u see spark then your getting spark to the plugs second check the fuel delivery on most cars on the fuel rail u will see a bleeder valve that will have a valve stem cap on it.(looks like a valve you would put air in) after turning the over push in the stem with small tool. if fuel squirts out then u have fuel coming to the rail and can rule out the fuel pump. no squirt then your fuel pump may be out GL

Have been given a 98 sunfire,it turns over but acts like it is starving for fuel or isn't firing. it doesn't backfire so i don't believe the timing is off. What else could it be?

All cars need fuel spark and air. So make sure the spark plugs are firing and that their is fuel pressure at the rail for starters.

What will make the truck not start up but its getting fire, it wants 2 start but not turn over

Three systems in engines:

Fuel delivery (fuel mixing with air to burn and making it to the spark plugs)

Ignition (lighting the fuel on fire)

Compression Building up pressure to fire the fuel

It is possible your engine could have low compression if it has ever been run low on coolant or oil. The engine might spin or turn over but not have fire at the spark plugs. If you are correct that the spark plugs have fire but it will not "kick" or run then fuel delivery is where I would start. See if your fuel rail has fuel in it by pressing the fuel rail valve:
If you have fuel there under a good amount of pressure see if one of the plugs smells like gas after cranking. If so the problem is not the fuel, move on.
If you don't have fuel at the Schrader valve the problem is in the fuel pump and system.
refer to a manual on how to remove the pump from the tank and replace it. This problem has signs before it goes bad. Hard starts and running rough when hot.

Good luck

Won't run. has spark (weak)fuel to fuel rail.

id be leaning twords a coil pack on this one, if the spark is weak change the plugs and wires first since its cheaper, then if that doesnt cure it change the coil pack.

Install spark plugs does the fuel rail have to be removed? if so how do you remove fuel rail

hi not normally , all that you normally do to replace the spark plugs is take the HT leads off the old ones, be sure to do this one at a time and not all together as you may loose the firing order, but, no there is no need to remove the the fuel rail...hope this helped
