I replaced the fuel injectors but why won't my car start?

Possibly blown fuse - 'TEST' all fuses using a test light .. IF all fuses 'test' ok - using a *noid light* - 'TEST' for injector pulse signal .. IF unfamiliar with how to do these test - seek *hands-on* help from qualified personnel.

Toyota corolla 2000. I have similar issues. I changed one of my coil that was detected after a scan and the check engine light started to blink and after a while it went disappeared. Since I bought the car used February 28 this year, the check engine light has always been on, it's going off now scared me. Now after I changed the plugs it start fine but refuse to accelerate. What could be the first suspect please as I am traveling with it tomorrow. OBD scanner is not available at my present location. Thanks Andy
