Question about 1994 Oldsmobile 88
If the check engine light comes on, there should be a code stored in the computer. Exception being that the shut down was caused by a non computer problem, in which case the computer thinks you turned the engine off on purpose and will not set a code (a bad ignition switch can do that) Even without codes, there are numerous tests on individual components that can be made. About the only two components that need special test equipment are the ignition module and the computer itself. Although it is tedious work even the harness itself can be tested.
Any shop that claims that they need codes to fix a vehicle should be ashamed of themselves, and perhaps should not even be in business.
The only limitation on what a shop does should be the limitations you place on them as far as how much you are willing to spend to resolve a problem. Either find a shop with some experienced techs or make the car into a project, and do it yourself. Armed with the proper information and a decent volt/ohmeter and some patience you are likely to be able to repair this. And yes, it could be a module or pump/ pump harness but you would need to do some testing to find that out.
