You are losing either fuel or spark. Need more details, why is it not starting? You imply it is running ok for a few miles. I'd expect an excess of current being drawn by one of the circuits. Which one? That is why you have to know WHY it won't start so you can investigate that particular circuit.

That means the transmission is going into Limp mode - something's wrong that is making the car believe it can be damaged by the speeds the upper gears will allow you to reach. For starters, check the fluid level (or just change it - it's not a bad idea), and disconnect the battery for an hour or so to put the ECU into relearn mode - this will clear current fault codes and allow you a fresh start to see if the condition reappears, or if it was a fluke failure of some part that caused the car to repeatedly go into limp mode.

low fuel pressure can be caused by fuel pump or pressure regulator. The regulator is on the upper side of the engine and looks like picture below. Check the vacuum hose all the way to see if it has a loose or broken connection. The regulator is much easier to replace that the pump, so I always recommend one replace the regulator before the pump. If you know someone that can check the fuel pressure before the regulator, you can actually determine which part is bad.

No the mileage is not stored on the computer. Junk yard is ok if you get a good unit. Make sure it is from the same make and model. the auto and manual units are not the same.

Try calling a junk yard that caters to imports. Some even have a parts locator system that can direct you to which junkyard had the part you need. Otherwise it's a trip to the dealer parts department.

1990 HONDA CIVIC DX ENGINE LIGHT ON


More info needed. Is this a hatch back, sedan, or CRX? Is the odometer mechanical [old style] or digital [LCD numbers] The vehicle speed sensor [located behind the speedometer in the instrument cluster] drives both the speedometer and the odometer [mileage meter]. It sounds like an electric problem in the instrument cluster. Remove the instrument cluster and take it to your local speedometer repair shop. Look in the yellow pages for them. Or simply buy and install a used instrument cluster from a junk yard.

Speedometer just stop working


Generally there are two reasons that keep a speedometer from working. Either the Sensor in the transmission has failed of the speedometer head itself is no good. The spped sensor can be purchased at most Automotive stores and installed relatively easy. I always suggest trying this first because its the cheapest. You can also purchase one from the junk yard however I don't recommend this unless you are just wanting to save a few bucks and use it for a test part. If you replace the sensor and the speedometer still fails to work then chances are it the head and then you can either purchase another from the dealer or the junk yards. However make sure that you note the original miles and the change.

Computer problem


I would check on Ebay or a local salvage yard for cost of the computer.
I had a computer changed in a 1990 Cadillac Deville that cost only $80 for the part and $200 for the diagnosis and replacement labor. Probably a 2001 Buick LeSabre would cost more, though, unfortunately.
