Neglected 89 Corvette
Hi All,
I'm new to this forum and have a serious problem, and I hope you can help.
Car has been sitting for 5 years. When driving car 3-4 miles it will shut down shortly after operating temperatures. Former owner changed computer thinking that was the issue. 4 injectors read approx 16 ohms and the others between 5-10 ohms. Injector resistance values drop slightly with rise in engine temp.
The car runs well when cold. I checked the computer ground and it appears to be ok and secure. I do not even know if this is the correct computer. The computer number is 7-7165 and the DC code is 0310ZN. My local Chevy dealer told me the prom is correct, but the computer is a remanufactured unit and they weren't familiar with it.
Fuel pressure is good. Spark is good.
Note: I pulled the computer out and the tag on it cautioned stating any resistance value less than 20 ohms will fry the computer. Could that be a problem and has anyone heard of that?

this should be moved to the c4 section
but
those injectors are fubar
if they are OE they are way overdue to be changed. if i remember right you can use the ford orange 19lb injectors on a stock L98 since they flow roughly 21lbs/hr at GM fuel pressure
used sets are 50-60 bucks on ebay
