Hi, I have a 95 honda civic with a d15b. My car starts and will stay running then 5-15 minutes later it will just shut off. Once it shuts off it won't start again. I wait like and hour or so later and try and start my car it'll start up and shut off shortly after. I've replaced the spark plugs and wires, rotor and cap for the distributor, ignition coil, fuel filter and fuel pump and strainer. I don't have alot of money to take to a shop and have a mechanic look at it. Plz help

 

Have yo checked to see what is missing when it stalls, fuel or spark?

My guess is, [as you have checked/replaced most everything else] the PGM-FI Main Relay... Main Relay Fix and Troubleshooting (Honda, Acura) a common problem and easily fixed. 94

 

i have replaced the main relay that and the fuel pump were the last ones I replaced recently

 

For testing purposes, unplug the primary O2 sensor. Does this eliminate the problem?

Also Ohm test the ECT sensor.

 

I have aftermarket DC headers and downpipe but it doesn't have a hole for the o2 sensor. But the guy I got the car from said he was driving it with out the o2 sensor since he had the car. So I bought stock intake manifold and tried using it to see if it was the sensor and it still did it. Could it be possible that my fuel pressure regulator? Or how about my distributor?

 

Do you currently have an O2 sensor installed? If so:
