im new on here so bare with me pls i have alot to say

recently ive had alot of problems with my car.. the vacuum line broke, power steering seal went out my steering is feeling funny, and now it wont start.

i have a 97 z28 5.7l..150k miles a4

i fixed the vacuum leak

fixed the power steering by putting stop leak in

the steering i cannot figure the problem out. the steering feels like im floating and the steering wheel.. guees you can say pops when turns.. thought its my ball joints but doesnt do it all the time..? could use some help with this also.

but my car stopped running when i fixed the vacuum leak, power steering leak and i also serviced the tranny.

i believe it ran outta gas so i put more in, but it still wont start.. could this be my fuel pump?
filters?
air in the line?
relay?

i was also told it could have been because the power steering fluid got onto my distributor and isnt letting it fire.. but my car turn over and almost fires.. if i pump the gas petal 3 or 4 times before trying it makes a combustion and wants to start but doesnt, i checked my fuel pressure with my hand and it has litttle pressure. not much suction.

and if its my fuel pump how would i go about replacing it??
