I havn't had one actually break starters, but these are famose for injector leaks...I would have a fuel pressure test done to verify the fuel pressure leaks down overnight...if so the top of the intake should be removed for inspection of the injector assembly. If the fuel is entering the cylinders and flooding the engine, it will put load on the starter.
So the check engine lamp has also been comming on, sicne the problem began?
Within how many miles were the starters replaced?
When the engine cranks and "kickback," as you say...do you hear the engine fireover before the starter brakes? Is the nose of the starter breaking?
What brand is the starter your using?
Was the hard starting problem evident, before the actual starters started breaking?
Do you know the diagnostic code that is being set?
I have seen the distributor cap/rotor be corroded and cause kickback and hard starting concerns. Here is a bulletin from GM pertaining to that problem and even lists a replacement distibutor if the screens are the problem and can't be repaired.
This bulletin is being revised to delete a model and add information to subject and inspection of distributor vent screens. Please discard Corporate Bulletin Number 03-06-04-041 (Section 06 - Engine/Propulsion System).
Some customers may comment on poor engine performance and the Service Engine Soon/Check Engine light being illuminated. Upon investigation, the technician may find DTC P0300 set.
This condition may be due to high levels of internal corrosion in the distributor, causing misfire, rough idle, stall and Engine Cranks But Does Not Run. This corrosion is attributed to a lack of airflow internal to the cap caused by the vent screens being clogged with debris.
Remove the vent screens and inspect the internal components of the Distributor Ignition System using the procedure listed below. If the distributor base has to be replaced, the vent screens will also have to be removed on the new distributor. If there is evidence of this internal corrosion, replace the affected component. Refer to the appropriate procedure in the Engine Controls sub-section of the applicable Service Manual.
Important: All of these inspections can be done on-vehicle.

No problem...take your tim.It's too coincidental that the codes, showed up the same time the problem began, and the fast idle concern. I doubt the new injectors are causing the problem either. Also, check to see if the positive cable is tight on the battery(s)...if you pull up on the cable and it can pivot on the battery terminal, than the cable is loose. Try to tighten it, but if it doesn't - let me know. While your there, check to see if the negative cable is tight as well. If the positive cable is loose, it can cause a voltage drop to the engine computer and cause performance and starting issues.
Hi, there...what about the codes for the check engine lamp, were you able to retreive those?
