1989 Bronco II XLT HARD STARTING!!!!

I have a 1989 Ford B2 XLT 5-speed manual, anyways i have hard starting i am my own mechanic, but this is driving me insane. I have replaced the air filter (K&N), fuel filter (motorcraft), distributor cap & wires & spark plugs(motorcraft), fuel line, proper maintainance (oil change synthetic, shocks, etc.), alternator, all wires running to and from battery, battery.
but i cant seem to fix the problem itself, i had another mechanic tell me my fuel pump is weak but not sure if it is the problem (dont want to waste $300 on a motorcraft one) but if it will fix it, i will, buy it because it is embarrasing cranking a engine more than twice. i am just looking for confirmation or could it be something less expencive.
Thanks, any help appreciated.:rolleyes:

P.S.
i took it to NTB two days ago to get my tire repaired (nail in tire), and once it was done it took the guy 6 starts for 10-20 seconds, i had to go out and start it b/c the people didnt want to be held liable, and it took me twice, i need to fix this problem NOW it has been annoying me since i bought the truck. the fuel pump turns on when in the "on" position for like 1-2 seconds then stops, and when running it is very noisy. plz any help on solving the problem will make one less man crankin his engine a million times.

look like a bad fuel filter i woud change it enyway, and if you dont want to.just get the fuel pressure reading dont have the spec under my hand but if under the spec you got your problem. im no mecanic i do stuff and know stuff a bit but it look to me since i had a similar problem this is the problem good luck hope help you a bit (advice)
