The first thing you will need to do is have someone scan the computer for trouble codes (service engine soon light). This will tell them which system is causing the light to come on and will lead to the cause of you hesitation and stalling. I hope this helps! Thanks, Ron (AutoPros-Buford GA)

First, where did you get the pump? Second,did you replace the fuel filter? Ron is correct, retrieve the code(s). You don't need a scanner. If it is a 12 pin DLC. Take a paper clip, find the DLC(diag connector), it's directly under the steering column, make sure it has 12 not 16 pins and connect the two upper right cavaties together with the paper clip, then turn the key on. Watch the check engine light flash. There will be a sequence of flashes. Count them out, that will be your code or codes. This procedure will only work if it has a 12 pin DLC. If it is a 16 pin then you will have to have a code reader/scan tool. I know you can do this. If you need more help, my e-mail address is AUTOKNOWHOW@earthlink.net.
