Default Hard Starting C4

Lately my '90 is hard to start after sitting for a day or more. Once I start it, it is fine for the remainder of time until it sits overnight again. The engine turns over for quite a bit of time before it finally will fire. I'm thinking it is either a fuel filter for a fuel pump problem. I'm leaning to the fuel pump. From what I read, even the pump isn't to bad to replace. Any thoughts would be appreciated. Thanks

put a guage on the fuel rail..turn on the key....see it comes up and stays up for a few minutes....doesn't sound like your pump...should come on for two seconds....
