At the beginning of your question about the cold start, I would say check your battery voltage and connecting cables for corrosion. (Even inside the insulation)...but with the flashing check engine light, you need to get a code reader, hopefully the code thrown will help you pinpoint the problem. You can get ODB2 readers on Amazon for like $20, and stores like Autozone will generally let you use a code reader for free.

check your fuel pressure. it could be your fuel pump is on the way out. f/p should be around 65 psi.
