check for spark at a plug for starters if you have spark check fuel pressure and injector pulse.
I think you can also check codes by cycling the key on and off 3 times leaving the key on and counting check engine light flashes it will flash each code once so you may have to do it a few times to get the codes if any 55 is end of codes.
