Volvo Repair: 1989 240 volvo, volvo dealer, volvo 240

Question
I have a problem getting my 89 volvo 240 to start. I think the problem  is with the fuel injectors and I have already replaced the relay.Can you tell me where I can get parts in the Dallas / Fort Worth are? And how can I tell if its the computer thats bad?

Answer
Mark, there are many things that can be bad.  you have 2 other things beside the computer that can be bad.  1 is the speed sensor and the other is the ignition power stage.  Theres the Volvo dealer in Dallas and there are 2 places in fort worth that has parts.  There are many test to perform to see if the box is bad.  I suggest you get a Volvo shop to help you out on this one.  Too involved for me to explain.  Roger
