What is your question?
I just got given a 1990' Toyota Corolla 5 speed manual with a 16v EFI 1.6L. I changed my fuel pump the other day and the pump works. It started once and bogged out and died like it had no fuel or pressure. Now it acts like it's starving for fuel even when I spray starting fluid inside the carb through the air filter. I know it's electrical I just don't know where. All the fuses and relays work just fine if it's not the fuel filter what other problem could it be.
What makes this problem better or worse?
I haven't been able to make it start that's it. Everything works on the car, it's got 188,000 miles on it and I know if I could get this taken care of it'd pass smog and be a good car
How long has your 1990 Toyota Corolla had this problem?
More than a week

Hi - Dave here, contributing to RepairPal and providing expert advice since 2010. I appreciate you've been making attempts to resolve the concern. Testing for what isn't present is what's essential. Concern #1: there is no carburetor for this car. You have a fuel pump, fuel pressure regulator and fuel injectors which spray fuel into each of the four cylinders. Your spraying of starting fluid may have zero effect depending on where and how you're spraying it. Concern #2: It isn't necessarily an electrical concern that you are experiencing. The engine needs: fuel delivery, proper air (not too much, not too little), ignition spark, cylinder compression and exhaust flow to operate properly. I would be on the look out for an air intake leak - are all the air tubes intact? Any vacuum hoses missing or loose or leaking? PCV hose? I would perform a fuel pressure test at the fuel rail to see what kind of fuel pressure is present with the key on / engine off, and if it remains steady. Testing is essential. Guessing and throwing parts at the vehicle has zero value and is a shot in the dark at best. Even worse, you could replace a part with one that doesn't properly work or install it incorrectly and create more problems and variables than you had in the first place!
