Ok I just finished(sort of) slapping in a h22 in my 94 lx accord. Thing will start up, then die immediately. Then it won't start at all until I cycle the key a few times and even then it's difficult. When I get it going sometimes the thing will kill and I try to give it gas, but it acts like it's not getting it. It has fuel pressure and continuous spark. Fuel pump worked before swap. Vacuum hoses may not be perfect. Why would it start and kill right after. Injectors dirty? Vacuum lines?
