Cadillac Repair: 1990 cadillac deville wont run, fuel starvation, starvation problem

Question
I took my caddy to the shop, cat was clogged, they said it wasnt the problem. They replaced the oxygen sensor gave it a tune up and ran for about a mile and lost power. They then told me the cat was clogged. Now the y said the next morning the car wont start unless you spray starting fluid in the throttle body. Then it runs until the starting fluid is used up. They said they have the right fuel pressure to the throttle body. They said theres no engine vaccum, what could be the problem?

Answer
Hi Steve,

Did you think of trying a different shop?

The vacuum leak you would need would have to be massive because the computer should pick up and compensate.

What are they doing using starter fluid on this thing? Are they nuts? They could blow a head off this 4.5! Never, Never, Never!!!!!!!!

Something does not sound right. From what you describe, it sounds like you, in fact are not getting fuel.

Without being at the car, I cannot accurately tell you what the problem is, but as I said, it sounds like a fuel starvation problem.

Good Luck!!!
