Why does my car start then die when i let go of the key?


You have an ignition problem. For some reason it is not staying engaged and could be as easy as a spring in the tumbler.

Need to find out if there is spark while cranking first. Check at the coil wire first then at a plug wire.If there is spark at the coil and not at the plug the fault is the rotor or dist. cap.If there is no spark at all,suspect the ign. module. If there is good spark move on to the fuel pressure check.It needs about 40 lbs. to run.

1999 range rover se changed fuel pump, truck still wont start, relays and fues look good.


why you have replaced the Fuel pump? who advised you to do so?
be guided as follow 1. on the Engine Side on the top there is a fuel rail for the injectors. turn the ign. key to the second position (on) and check the valve located on the fuel rail if fuel is coming pressurized and still won't work. then open on of the spark plugs wires and check if spark is there. (Be Careful doing that). if no spark then is there any message comes up on the Dash? if not messages then you can check the Crank Sensor if no current being generated from the ign. coils.

Pull one or two sparkplugs and check them for moisture; not fuel, but for water beads.
I don't know how long your engine ran after losing coolant but there is a chance that you lost the head gasket and have gotten water into the cylinders.

I have a new fuel pump but my car still wont start why ?


What makes you think its was the fuel pump in the first place .
What about the spark /and the plugs/and the coils/and can you hear your fuel pump working when you turn on the ign key,can you hear a motor running in the fuel tank, if not then take off the feed pipe to the engine and get someone to turn on the key and petrol should come out ,if not either the pump isent pumping owing to no power to pump /fues/broken wire to pump/or fuel filter needs replacing .
If you can hear the pump and fuel comes out the pipe from the tank .and the injectors are ok then check out the plugs for spark/ take out 1 plug and put it in the pluglead and lay it on the engine and spin it over if a good blue spark then you have no problems with that side of it
but it will be 1 of the 3 things.. Let me know how you get on Ron

1992 Ford F-150 Ignition lock switch


Do you have a tilt wheel? If so you're only half the way there. The upper actuator is broken. And you got to get into the column further. As for the trick to get the cylinder in. Don't matter if you got a tilt or fixed wheel. Go to the top side of the column. About 2/3 the way down it you'll find the Ign Switch. A rod will be coming out of the top going towards the wheel area. Push it into the switch till the inst panel lights come on. That means that the Ign switch is in the 'ON' sopition. IE all the dash panel lights come on. There is a key on the tumbler that matches to a key in the ign gear. Than just incert the tumbler into the gear and turn it to lock it in.
If you got a non-tilt wheel then it sounds like the bottom of the tumbler is broken off and is still in the gear. If so do the same as above with the Ign Switch. That will align the key so you can take the broken part out and put the new Ign tumbler in.
