Not really it is still doing it I'm gonna take it to the shop

 

What does the fuel pressure drop to during acceleration or at highway speed. 10 is pretty low at idle.

 

I've got my fass on so that elimantes that

 

That's good.
Have you visually checked the wiring to the PCM,and ABS controller I agree its electrical.

 

I've checked all the plug ins on the passenger side firewall. I've also investigated as much wiring as I can. I guess I need to do a more thorough investigation of the wiring. There is either a short somewhere or a bad control module. Does the tps communicate with the speed sensor?

 

To my knowledge the Powertrain Control Module takes logic signals from all the various sensors: crank, speed,timming, fuel,TPS, and processes them if it sees an open circuit or out of range signal usually only milivolts it throws a code or a warning light.
I believe that the ABS controller works the same only just for the ABS. It may all feed to the PCM for setting the lights off in the cab. just not sure without digging in a schematic.

 

I guess I need to see if I can come up with a wiring diagram and go from there

 

Cool keep us posted thanks wish I could be of more help.

 

I will thanks for the replies let me know if you think up anymore ideas

 

I forgot about this little tool I was digging back through some threads and found this.
