I was looking for a similar answer for a Lincoln Town Car - '95.
I found some information that should help you.
It includes information about most - to all - ABS systems and directs you with some basic info you can search for further.
Here is the info: http://www.aa1car.com/library/abscodes.htm
Low brake bressure can be caused by a worn accumulator, poor pump performance, a bypassing brake booster or an inaccurate pressure sensor. To test your brake accumulator, turn the key to the on position and pump the brake pedal. A properly functioning accumulator will give you 25-30 brake applications before the low brake pressure light illuminates
1992 Chevy s10 jumps out of 5th gear
Yes,
No carburetor on that 89 S10. It would be throttle body fuel injected.
I have an 89 s10 with a 2.8 V6. It gets about 22 city, 25 highway.
Turn your ignition to the on position. If an amber lite that reads ABS or Anti-lock comes on in you dash, you do have abs brakes.
The Exhaust Gas Recirculation Valve on a 1989 S10 is located in the valve cover. It is toward the front of the motor.
yes they have brake boosters
It will not bolt directly in but you can fabricate it to fit.
NO, They will not interchange.
The 89 model does not have a VSS.
If you're thinking of a fuel pump inertia kill switch, the 89 S10 doesn't have one.
