I have 94 civic Ex which I have just rebuilt the engine (700miles on it so far) and now when I drive it around it just dies randomly. It has compression, spark, and no fuel pressure when it dies and I crank it over. Then I let it sit for awhile and it will start again run for about 15 mins and die. With the same symptoms comp, spark, no fuel. There is no CEL. I think this is a symptom of an electrical short in the fuel system. The injector seals were replaced just 2 days ago and then the problem started to happen. I have two ideas about what it could be, a) the mechanic is a monkey and messed something up, or b) the kill switch hooked into the fuel pump power line is shorting out. What do you guys think?
