Hi I have a 93 Honda Civic with a 1.5 non-VTEC. My car starts I’ve been driving it for the past few days I change the main fuel relay, changed the fuel pump. The problem I’m having is that when I turn the car over it will die immediately it’ll start and then die. So I change the fuel pump. And it was still doing it to me so I change the main fuel relay. The next morning I went to go get coffee with my girlfriend and then we went to Walmart and when we came back out it turned the car over and it almost died but caught itself. Any ideas??
Check if there are any OBD1 codes.
OBD1 was so crude that you could have engine performance problem before the Check Engine light would turn on.
Could be a failing ignition switch; the electrical part of it. That has been a problem for decades with Hondas. The main relay and fuel pump has power routed through the switch and eventually the high current draw will do in both the switch and relay.
