Thank you for asking your question on Just Answer.

There are 3 things that will make the 1989 engine coke out , 1 fuel pressure regulator. 2 ECT (engine coolant temp sensor) and ACT (air charge temp sensor) Start with checking fuel pressure (normal 32 to 35 PSI) if it higher than that its likely a bad regulator.

Reply to Ron's Post: Could it be the regulator that switches off the fron tank from the back tank so I have gas pressure?
Expert:  Ron replied 8 years ago.
Usuall when its a regulator it floods the engine with excessive fuel pressure. Making it choke and blow black smoke.
