A 1988 Buick Century comes in with an overheating problem.
A technician drives the vehicle with a scan tool connected
to view the computer's datastream. The technician is interested
in monitoring the engine cooling temperature reading and the on/off
command information for the engine cooling fans. On the road test,
the technician notices that when the computer turns on the cooling
fans several datastream lines have scrambled unreadable data.
This scenario is normally a hallmark symptom of a faulty computer.
The computer is replaced, but again the same datastream lines are
unreadable when the cooling fans are on. A call to the scan tool
manufacturer reveals that the car's computer is fine.
The manufacturer's representative advises us that they are aware
of this glitch that occurs when their brand scan tool is hooked
up to 1988 Buick automobiles. They are going to correct it in a
future software update cartridge that we can buy when it’s available.


What happens is the fuel from the tank to the pump heats and boils.
It vaporizes in the line and your pump cannot pump vapor. With fuel
injection the pump is in the gas tank, providing full liquid pressure
to the injectors. When you say after it gets hot, I think ignition
module right away. this is the most common problem when the engine
temperature is high, Module failure will sometimes cause the car the
stall when hot and restart when it cools. Should have it tested at a
shop. Ignition coils will do this too. Fuel filters should be replaced
on schedule. It doesn't hurt to change a module as a preventive
maintanence function after the average lifespan has been exceeded

Üldiselt tuleks sel Buickil veakoode vaadata, annab ka huvitavat infot teinekord.
