Default Injector problems

Hi Everyone,
My 8 injectors died on my 90 coupe with only 3200 km on the clock. I think
the result of Ultra 94 and storing the car. Anyway does anyone know if a
1998 injector will fit in my 1990. Any help would be greatly appreciated.
The injectors I have are Bosch 280 156 045-750 don't exactly know what these are for but they look exactly like the ones for the 98.

What do you mean they "died"? Is the resistance too low/high, do they leak, etc.?

If they are only gummed up, send them to Rich at Cruzin Performance for a rebuild at $80/set with 48hr in shop time. His shop is in Big Rapids, MI, USA.

Well my mechanic said they were reading between 2 and 6 ohms when they
should be about 16 ohms cold. Another mechanic said the ethanol in the
Ultra94 dried out the rubber seals and shorted the injectors. Do u know if they can still be re-conditioned seeing as they still give a readingon the meter. :cool:

They should be over 14 ohms cold. The readings you have are really pretty low, and I am kinda surprised that your ECM hasn't burned the quad driver.

If they really are that low, limit driving the Vette as much as possible to keep from frying the ECM. Good luck, -Matt-
