Hi i recently found out that i do now have spark and gas flwoing to the engine yet it does not start. I purchased a new fuel pressure regulator and tommorrow i am goin to put it in. I am thinking that is going to be the problem. I did a test with the built in tester and got a code that said Throttle switch signal missing. could that be a big problem too? I reset it using the manual by clicking it into position but i am not sure that did the trick. I anyone has maybe a solution they could share i'd be very greatful. I have a 1989 740 GLE volvo 16-valve thanks so much.

It may be flooded, or need new plugs. While taking care of that, charge the battery.
Might want to clean the contacts on the throttle switch, and the internals if you can get to them.
Also, look for any broken wires on sensors--my 145 quit one day when one wire to the temp sensor used by the FI system came out of the connector.
