1990 lumina fuel pump

[svotta]

I have a 1990 lumina. recently it was stalling when it warmed up. i brought it to the shop and they replaced the crankshaft position sensor. So now it stalls and starts right back up and will stall again after driving it a short time. They said it is the fuel pump. The fuel pressure was slightly low. Are they right when they say the fuel pump is the reason why its stalling only when hot. Any help would be great.

When it stall you need to confirm at least 37 psi, or more guess work will lead to ineffective repairs, as other things can do this.
