I have fixed most of the problems with my 98 Suburban 135K.... Most having to do with power and remoting the fuel control unit. The problem I have now is that once the engine is warm it will not start.... It takes 10 minutes of 15-30 second turn overs to finally get the thing to fire...batteries at that point are almost dead... in the morning when cold it start right up....seems that the lift pump is working
any ideas?
