I have a Subaru WRX 2000 model. The engine stops on me while driving approx 15mins after i started driving. when i try to use my immobilizer to start the engine it cranks up but won't start. If i leave it overnight and try to start the car again it starts up though. It's been happening 3-4 times now in the same sequence. Drive for 15mins and it stops, won't start unless if i leave it overnight and try again...it starts then.What is the problem, is it the immobiliser playing up?

Last night I checked the battery and it was still good. I disconnected and then reconn ected both terminals and that brought the power back. When I turned the key the power went out again. I repeated the procedure but did not turn the key. Instead, I took off the knee bolster and tried to wiggle the wires under the dash to see if I could find the source since it seems to be related to the ignition. Nothing cut the power so I started it up and it worked fine except for the check engine light which was flashing that says I have a misfire condition. I drove the car 25 miles to work this morning and will be taking it to the dealer for a better inspection.

you should already have a wire shunt in the main harness for the tach. all you need is the sending unit and the gauge. the sending unit goes in a port on top of the transmission next to the engin bloc. the dealer ship will have the schematic for your specific vehicle and the right sending unit............please rate this

Do you have a manual boost controller (mbc) installed? I have a 96 WRX and had the same problem and so took out the MBC. It now runs sweet. If you don't have one check the vacuum hoses from the turbo to the wastegate and also to the boost control solenoid, make sure they are tightened with cable ties or a hose clamp.  Also could be your spark plugs make sure you have iridium ones, they out perform any others.

SOURCE: jump starting a car with an immobiliser

use another vehicle and start by connecting the jump leads from the negative on one battery to the negative on the other and do the same with the positive, the positive is the one with the cross or the red wires. dont worry if u get a little spark when connecting the jump leads its perfically normal, then simply start the other vehicle up and leave it running for aruond 5 minuates then try starting your can.(you may need to rev the other car up a bit to raise the power being transfered) be very careful not to put the jump leads on the wrong terminals.
i hope this advice helps u,
can you please rate this advice

Actually you should always hook the positive leads first. Positive from the "donor" car to the positive terminal on the "patient" car. Then attach a negative lead from the donor car's negative terminal to the CHASSIS or MOTOR BODY of the patient car. This is vital to prevent a surge which could possibly spike your vehicles ECU. Start the donor car first, and always be sure to put a little load on the patient car, for example turn the headllights on, before attempting to start it. If you follow these instructions you can not go wrong.
