Re: 89 tbi running & starting problem

Was the fuel pressure tested while the engine was running? How was it tested?

When you disconnected the MAP sensor, did it set a trouble code?

Is there a good vacuum supply getting to the MAP sensor?

Did the problem start all of the sudden, or was it a slow deterioration.

Have you checked the timing?

Have you removed the distributor?

If it is modified from what came stock from the factory, let us know that too.
