Problems after injector change

[Falle]

Hi guys,

I have had a Pittbull chip, Fuel regulator, Fuel pump and Black Beautys from ATR for a while now.Rest of the truck is stock.

I changed to Dephi #33 injectors. I also replaced the metal ic lines. After that the problems started. The truck idles good, but as soon as the engine gets hot, the ABS lamp turns on, the speedometer jumps up and down and the engine revs up alittle once in a while. I have noticed that when the engine is cold everything is fine. Has some one had this problem before?

Best regards
Falle

haven't seen that one before but is there a chance the grounds on the back of the heads got pulled and damaged during the install?

Did you pull the ABS codes, to see what they're saying? It's probably an electrical glitch, but it couldn't hurt to actually check out the codes.

For myself and others, flushing a lot of fluid through the brake system has cleared up weird ABS lights.

I am going to pull the codes and check the grounds tomorrow evening. I have noticed that these problems must have something to do with eachother, cause when the ABS light goes on that is when the speedometer and the engine rev problem starts.
I will update with more info when I find something.

Thanks for the help guys

Hi,
I pulled the codes and it was clean. I have checked every connector under the hood. I checked the grounds on the heads and they look good. I also called ATR to confirm that i got right injectors.

Is there anyone who has some other suggestions apart from these?
This is realy getting on my nervs.
