I have a 91 RS 305 TBI. First off it has a no start condition. Replace the ignition module, check the battery its ok. Once i awhile it will start but it feels when warming up it sounds off of tune, when you step on the accelerator engine will run rough or die...
Any suggestions where should I start checking first.

 

whats the tune up status on this car?

 

Sounds like a fuel pressure problem. Your pump could be going south on ya. Check for code 54.
