Bought an Actron code reader, heres the codes
511-EEC problem read only memory ROM test failure
811-fuel inject pump lever fipl signal voltage higher or lower than expected
89-lock up solenoid circuit failure OR converter clutch override OR exhaust head control failure
334-EGR valve postion sensor signal voltage higher than expected (close valve position)

Any guesses?

its highly unlikely

I still have yet to see a 94-95 ECM actually fail. Not saying it doesnt happen. But you have to do some pretty stupid **** yo get your comp to go kaput

511 is a hard code that cannot be fixed. PCM must be replaced. Disregard all other codes until you replace PCM. You have a fried ROM chipset, which stores the strategies for the entire powertrain control.
