I have 92 civic dx and ever since I had the car, the car would die out after starting it when the engine is still hot. After a long drive I go park my car and come back 10min later and when I start the car up, it would idle for a while then just die out. I thought first it was something with the engine or even the fuel pump. But I replace the engine with a b-series and did change the fuel pump with a b-series and I still have the same problem. What I do now is I wait for like 5-10min in the car turn the key to hear the fuel pump go on and then start it. Works fine if I do that. What you guys think the problem is?

 

anyone?
