Welcome to AF
You need to hit the New Thread button and start a new post/thread on you problem.
Saves on high jacking somebody elses thread.

Give engine and transmission and mileage info.
What brand of fuel pump and spark plugs?
And fuel pressure readings on a cold start.

First place to start would be to check and make sure your battery is good and properly charged. If that checks out, get a fuel pressure guage on there and see what type of pressure your getting.
