Question about 1990 Toyota Corolla
1990 Toyota Corolla: Accelerated very quickly on highway (pedal down hard), car started to shake and stutter and hesitate. Car did not shake so much as higher speed but when starting from a stop or when slowing down and accelerating, shook badly. Got it home, noticed white smoke coming out the exhaust. Lifted hood, liquid (coolant?) had sprayed everywhere. Noticed the cap on the water overflow had come off. When I tried to start the car, liquid spit out of the exhaust manifold. Can't start the car, but that may be due to to alternator getting wet. What could the problem be? I am thinking the coolant blew all over because of the loose cap and may have caused other issues...
Fill up coolant,cap it is bad replace,check hose,start car and look.

Could be any number of things, lets eliminate the transmission. Put the car in park and throttle the engine, is it snappy then? Or does it slowly rev up? If it still runs funny or isn't snappy, the tranny is not the problem. So it could be, weak fuel pump, fuel pressure regulator, or a ditributor problem. Could be a sensor to, but I've had 4 corollas and have never had a MAF sensor or others go out yet. I have had problems with the items I listed.

SOURCE: 90 corolla efi problem?
Classic fuel pump failure, Efi fuse runs the fuel pump now its open and it won't start. With it cranking and not starting add a little fuel to the air inlet and if it (flashes off ) ( runs a few seconds ) there's no fuel and the fuel pump is the most common cause. The pump is in the tank and unles s you feel that you as good as any pro mechanic and have the experience then let a pro do the work as the danger is high even for a pro.

I would look at the fuel delivery system. Change the fuel filter if it hasn't been done lately. Also get the fuel pressure checked. I don't have the specs but it could be that your fuel pump is getting worn and occasionally has trouble pumping enough fuel to the carb. It's also possible that your carb may need to be overhauled. They do wear and get build up in the pasages over time. Also check to see if your warm air valve in the air cleaner is working. It is possible that your carb is icing up in the cold weather and it is more likely to happen at highway speed.
If you need to get the carb overhauled take it to a shop that specializes in this type of work. You will be glad you did when you get it back.
Hope this helps.
