Hi I have a 92 Civic HB with a 93 LS b18a1 with a 93 GSR Cable tranny wit Hydro conv. I'm having problems with the Main Relay Assembly that's pluged in under the dash(which also activates the fuel Pump). When I turn on the car the only way that the pump in activated is if the check engine light stays on and if the check engine light shuts off, the fuel pump does not pump enough fuel for the car to be driven but the engine stays on, if I try to shift on any gear to drive the car tries to go but it dies right away but it stays on... THE RELAY ASSEY ALSO GETS HOT WHEN CAR IS ON, IS THAT NORMAL??? can it be some incorrect wire code on the ECU??? I have no clue..... I had this problem before and replaced the relay and worked fine for like 2 months til now.... get I get some help on this plzzzz!!!! Thank you guys!!!

 

Replace the fuel filter and then check the fuel pressure.

 

i had a 90 acura integra that did the same thing it turned out to be the ground on the sending unit they rust up pretty bad some times

 

What codes are you getting? If you need another Main Relay Assembly, I have one for $15
