1989 Riviera: I need to find out why my car quit running..3.8 liter…

Customer Question
I need to find out...
I need to find out why my car quit running. I have a 1989 Riviera with 3.8 liter v.6. It just stop running. It has been running on 4 cylinders for about a week now. I put a coil pack in it and it did not help it. When the garage put the car on the machine to scan the computer, it would not work. Meaning it would not scan it. It just showed a bunch of stuff that was not readable. But the codes on the dash read a code 27 which is a drivers module circuit, which comes from the comnputer. I don't know yet, if it is getting fuel. I have not checked the fuel line yet. Someone told me those engines are bad about break timing belts about 100,000 miles. I have a 140,000 on this one. It has always ran great. Do you think it jump time, or could it be the computer possible. Does that computer control that much of that car. Help Please!

First thing Patricia you dont have a timing belt on your car.You may have a problem with the ingition control module.It is under the coil packs.If the engine is running on 4 cylinders I dont see fuel being a problem.I would also have all your fuses checked and make sure that the battery terminals are clean and tight.Please let me know what you find so that I may further assist you,Don

The terminal are clean. The car cranks with no problem. I had the plate under the coil pack tested and it tested good. Does the fuses have anything to do with that? I will check them.
GM Mechanic: Don Knight, ASE Certified Technician replied 8 years ago
I need to know if you are getting spark at the spark plugs. If you have spark and you have fuel pressure than you need to do a compression test. Please let me know what you find,Don

I found out the problem. The car left me sitting on Saturday. The fuel pump was going bad. It is in the shop right now. After a 85.00 tow bill. Thanks for your help.
