My car is not getting fuel. Can you help? on 1993 Suzuki Sidekick

I had my head gaskets replaced and when I spoke to the mechanic he said the fuel pump would work if he wired it to the battery, but not on it's own. He thought I needed a new computer. I installed on and the problem still exists.

you need it properly diagnosed to find the issue. get it to someone who can get to the bottom of the issue.
