No I have not check it, but.... do you really think that working OVP is needed to start a car?
I must tell you, no it's not. Engine without it, will be running rough and it will take a while to start it, but will be working. Even if you take of whole ke jetronic unit and put some gas or starter fluid diretlcy into throttle body, engine must to "make some noise"
Besides, OVP in this car is working correctly. IAC is opening, cold start injector is spraying some fuel and fuel pump is also working
