1990 Oldsmobile Ciera car wont start

I changed fuel pump and the fuel pump relay and the fuse still does the same thing. Only starts when I spray brake cleaner into the air intake? Why? I am into this $150 and really need to fix this any suggestions?

Do you mean the gray wire by the tank?

Yes it lit up when tested. When I depressurize the valve in the engine that looks like a tire valve then click the key about 10 times I only get a dribble when I press that little button with a screwdriver, I think I may have bought a bad fuel pump from auto zone but a mechanic said without looking at it that he thinks the computer is bad because it happened after a big rain storm and there is no way to test to see if it is bad I just have 2 replace it and cross my fingers. Well I am a single mother out in the country trying to fix my own car im wondering if he might think im a sucker and just wanna make some money on this opportunity. What is your opinion about the computer?

Thank you. How do I check if a ground wire is good since it doesnt light up when tested? Would a multimeter check the continuity? Is that even what I am looking for?

It did light up. BUt yesterday I tested the old fuel pump by hooking it to the car battery and it worked. Hmmmm. I am so frustrated with this car.

I had a friend stick an air hose in the gas tank through the nozzle where you would put the gasoline. He blew some pressure in there I tried to start it a bout 3 hours and it didnt want to start but eventually it did. What do you make of that? But today it didnt start.

Just wanted to update you, I took it to a shop and it turned out that the oil pressure sending unit was the problem. Who knew? I would have never guessed.
