Car will crank and usually wont start on 1st attempt. I crank a 2nd time and it starts, sometimes it takes awhile of cranking on 1st attempt or 2nd attempt, by awhile i mean just a bit longer then the usual startup time to where u know its not somthing thats normal. someone mentioned to me it could be the fuel pump, my car has 111,000 miles. If it checks out to be my pump is it worth replacing with stock replacement or somthing like a walbro unit? at the moment im not sure of my future plans for the car so im thinking of just going with whatever the oem replacement is. Also if fuel pump is dying would it be effected while the car is running...or is it just the initial start of pumping the pumps have trouble with. Reason i ask this is because my cars gas mileage has been pretty crappy lately
Is my Fuel Pump dying?

Walbro is the OEM pump manufacturer. Good stuff IMHO.
Most folks will recommend getting a larger Walbro now so you don't have to redo it later. Not a bad line of thinking.
Extended cranking or needing to prime the pump multiple times can be a sign of a weak check valve in the plumbing. It doesnt necessarily mean the pump is on the last legs, nor does it mean that a new pump will fix the issue.
I'd not look at the pump itself as a reason for bad milage. If you see oxygenated fuel (like we do here), that can cause a drop in milage alone.
Pulling codes and noting fuel pressure (preferably as you prime the system [to see how long it takes for pressure to reach 30 PSIG]) is always nice.
Good luck.

dont you have to drop the tank to change the pump, and how good are holley intank pumps. I looking at buying a 255lbh pump?
Yes, you drop the tank. Have a new tank-to-filler gasket (20 bucks) ready to go on as well.
IIRC, Holley is a repackaged Walbro (Many companies take a walbro and toss it in their own box).
Good luck.
