dead injector

dead injector
I have a 2001 grand Caravan with a 3.3
The injector on the #1 cy is dead, I determined this by pulling the fuel rail and injectors out and cranked engine over so to visually see that its not working.
went to town and got new injector and plugged it in but still dose not work.
What else could cause this ?
Wiring harnes ?
pcm ?
FYI, When cranking engine with injectors out, one should disconnect coils so the spark plugs don't fire. Learned this the hard way, luck to still have a car !

Most of the time you can just separate them, remove the terminals from the connector and heat shrink over each one. This is if they are not damaged. I do this sometimes when the customer is short on cash. If it was mine I would go find an injector harness from a junker. The last one I did, the guy came back a week later with a dead #6 injector driver in the PCM. Not because of the repair but they drove it a while with a shorted injector ground. (in that harness) Even though it does run, be careful about driving or running it until you get it fixed.

I got the new "rebuilt" computer, got everything back together . When I started it , it did'nt want to run very good, kept cutting out, and would'nt idle .
A friend told me that when he took injectors out and put them back in he had to drive the car real hard for awaile to get them cleared out. So I drove the car down the road and after a few miles it seemed to run better, but when I slowed down and re-accelerated it would start cutting out till I got it back to speed (60) . In the garage
it idles better but when you accelerate it cuts out .
I'm not sure if I just need to drive it some more or if there is something else wrong.
Any suggestions?
