Default Injector question

Will 94 factory injectors work in a 93? Everything looks the same but not sure of the electical requirements.
Thanks

Without doing the small amount of work for you why not just look up the replacements and see if the same part numbers are listed for both.

or go to most any parts store website and search the parts and note any differences. They have the spec listed and compatable yr make and model.

If they are the factory Multecs, I wouldn't use them.

Will they work - yes, you may need a tune to optimize them
The 92/93 injectors have a slightly lower gph rating. IIRC 92/92 was 22ish and the 94 was 24 ish.

Thanks for the info. I have a no start condition. I am getting spark so I checked fuel pressure. I get 45 psi but it does not hold. I followed the flow chart in the Fsm and the result of that exercise is that i have a leaking injector. I was unable to determine which one it is thus far. I am going to check the impedence on each injector to see if one of them is electrically bad. From reading on the forum, it seems possible that one bad injector coil could bring the lot down.

I asked the original question because I thought of changing them all out with a set of 94 injectors that I have.

Thanks again
