What is problem when engine starts but won't stay running
I have a 1992 honda civic dx. It will start up but then shut off almost immediately. When I gas it-it runs afew seconds more but will die even when I gas it, after it sit. It will do same thing. I have changed fuel pump and filter. It is getting fuel and I can hear fuel pump. What can be problem? 2 weeks prior to this problem we had a radiator crack and there was antifreeze on engine. Can any sensors be doing this? I don't have a engine light on and I think car is so old you can't hook code meter to it. Any ideas?
