My 88 is a 1.5L hatch... So I bought the car for 50$ story is timing belt blew, head was pulled off and checked was good do new head gasket and new belt re installed, car would t start sat for 3 years, aftermarket fuel pump installed and it supposedly started and ran. When I bought it I changed the filter and he has the fuel tank half out and the other fuel pump jimmy rigged so I disconnected the feed like to the pump and ran a hose to a jerry can outside the car just to try to make sure it runs before I throw money at it.... So it will fire and start but dies right away sometimes I can get it running for about 30 seconds but then it dies off again.... Been poking around can't find much, what should I be trouble shooting first? I know the fuel is getting to the intake I pulled the line off and it sprays fuel when the key is on and pumps when cranking, so fuel is good.... I think next I'm gonna pull the plugs and make sure there is strong spark in all 4 cylinders.... After that I don't know, any help will be VERY appreciated

Plugged up carburetor?

If there is rust in the fuel tank you are gonna be in for a bunch of trouble.

I think buddy said there was.... Intake and throttle body have been changed out... But I'm using a jerry can as a fuel tank
