'84 starts but won't keep running
Hi all,
I'm hoping someone here can help me diagnose my problem. I Bought my '84 about a year ago and everything was running great until last week. I started getting signs of a dying fuel pump / fuel delivery problems. I was getting a power lag while accelerating. It would pause for a second after i stepped on the gas when speeding up. It stalled on me a couple times and seemed to be getting worse by the day. I replaced the fuel filter- no improvement. Finally it died while I was driving yesterday and wouldn't start at all. I put a new fuel pump in even though the old factory one was still making noise when I turned the key. Thought it might help but no cigar. No check engine light or anything coming up either. I replaced all the spark plugs and put a new rotor in the distributor. Now it starts but it won't keep running. Even if i give it gas it still dies out after 2 seconds. No revving after the initial turnover. Any idea what it could be? Any insight would be greatly appreciated. -Nick |

Check fuel pressure. should be 12-14 psi. Possible issue with fuel pressure regulator(on rear throttlebody).
More on this in 1984 factory field manual. Chilton is a fine manual. I always keep a couple handy to use as kneepads. Soft and absorbent. Best use. Don't have a genuine 1984 Corvette factory repair manual? PM me and I'll mail a CD copy. You can print just the pages you need. Just reprint them if you get dirt, oil or blood on them. |

The carburetor could also be loose or messed up the double carburetor setups are hard to work with so you might want to check that as well.
