following are the general instructions on the start of diagnosing any
electronically controlled engine or transmission problem.
engine and the automatic transmission (transmission control is only
for automatics, engine is still computer controlled no matter the
transmission type) in this vehicle are computer controlled and in
most cases when a fault occurs a fault code is stored in the memory
of the computer control module. There are exception to this, such as
the Mass Airflow Meter and fuel pressure problems. What must be done
is to have all the basic testing done such as a scan of the system
for fault codes as well as a check with a live data scanner tool for
engine functions that are not within range of normal, a trained
technician is required to know what is correct and what isn't, then
based on careful diagnostics done from a factory repair manual the
correct part is replaced or the wiring repaired or the computer
replaced (known as the PCM), which is very rarely the problem. Other
basic checks must be done as well such as mechanical problems with
the engine as well as engine state of tune and mileage on the engine.
The transmission can have mechanical issues as well such as no gear
engagement at all or a failed pump or other pressure related

My 1992 Chevy Beretta had
Did the engine overheat before the radiator was replaced? If so, there is a very high likelyhood that you have a blown head gasket and/or a warped or cracked cylinder head. Those aluminum heads are VERY UNFORGIVING when it comes to being overheated!

How to do a rear brake assembly
if you mean to replace the rear brakes,then you can remove both drums and look at how the brakes are installed and replace one side at a time using the other side to see how the spring system is fastened to the brakes to hold them in place.just remember the rear shoe(of both shoes on one side) is always the longer of the shoes if there is a difference in length of the shoe brake material.some brakes have a long shoe and a short shoe when you look at a shoe and compare it to each of the other shoes.some the shoes are the same length,in which case it won`t make any difference.

MY car does not have a spark and dont know the
This is a fairly common problem with this year of vehical
Normally you will want to look under the hood at the fuse compartment for the ignition fuse and see if it is blown also look under the dash to see is there is a fuse there too
Now if all fuses there are tessted and are ok than this would mean that your spark modulator or coil pac as it may be reffered to is bad i would test those first..
further more there is a crankshaft position sensor that may be bad too it is located on the engine block about half way down towards the middle and has a wire that is plugged into it check to see that the wires are all in good working order and are not wet if so it will shour out the sensor and need to be replaced ok?
Hope this helps out
Best regards Michael

I just rebilt my 2.3L and is has low oil pressure
My first thought would be oil pump. Did you replace it or re use old one? Also when rebuilding did you have block "hot tanked" (degreased and soaked in hot solution)? Is it ticking like oil starvation? It could be bad oil pressure switch if all sounds good. I'd check oil pressure with mechanical hand held pressure gauge.

I have a 92 Berreta
Sounds like you have a loose or corroded battery connection. That's the typical symptom of a bad connection, when you try to crank and everything goes dead. Clean and tighten up the battery terminals and all the ground wires. Also, check and tighten the wires on the starter.
