i have a 90 acura legend and its not starting.. im thinking its the main relay for the whole car.. not the fuel pump relay? i have a hatch that once had a bad relay for the pump.. but when i go to start it, it would still crank.. well on the legend it doesnt crank.. so im thinking not the relay for pump if im correct... so i go to pull this big black piece from right under the steering coulum and it says rise up control on it.. is that the main relay for the whole car? is that piece suppose to click when you turn the car on like all the other relays? maybe that peice is what i need to get the car started? any help would be great..

 

You're looking at bad ignition switch/connections, bad starter/connections, or bad battery/connections. If it were the PGM-FI main relay, the car would crank but not start.

 

everything is good.. but the car would not crank at all so i dont think its the main relay for the PGM-FI

 

Hi

My acid pump is not available for pH control. How can I use a substrate pump to control the pH when the value rises above the set point. I dont have any problem when the pH value falls below the set point as I do have base control.
