Check the connections near the throttle body.  Sometimes not pushed all the way in.

Thanks

I have checked that ,will check again

I'll post when I check it out

Thanks Jayce

hi

finally got out to check the connections ,pulled them both apart and re connected them, both were clean and seated properly ,reconnected the controller and nothing !! unless I'm missing something I think the controller is faulty

thanks

When you turn the key on, does the fuel pump prime?  Maybe a ground issue.  Any electrical problems will affect the handheld first usually.

yes the pump primes ,everything else is working properly ,but I will check the earth

the shop I purchased the unit from is contacting fitech to see what they want to do

thanks

See if your shop has another handheld and cable.  Try swapping to narrow down the problem.

wish I could ,the shop is in another state ,(Adelaide ) I'm in Melbourne  , its become a warranty issue now

I've sent the controller and cable back to the shop , just wait and see now

I would be willing to bet that it is the cable.  Seen this happen from time to time.

While you are waiting, here is a bit of advise.  I recommend that everyone get a fuel pressure gauge.   I write it so much, it comes up in my predictive text, haha.  Fitech has a $10 one that I use on my Pickup.  Simply drill and tap one of the fuel rail plugs.  Or, even better, get a gauge you can mount inside.

Monitoring fuel pressure for tuning and troubleshooting is very handy.  Fitech never suggests this.

Also, when you get going, set your AFR to the spark plugs.  Since an O2 sensor is added to an exhaust system, it is not calibrated to that system.  For instance, my camaro has has a set of edelbrock headers with O2 bung for the factory efi.  So far my AFR settings are pretty standard.  On my 67 C10, the O2 is placed in my exhaust pipe about 16 inches from collector.  My settings on this one are about a point higher, but with same results.  Make sense?

thanks for the tips

finally heard from the supplier and fitech tell them that the cable and controller tested fine and the problem may be within the throttle body ,have to check for 12volts at the plug !!!!!!!!

ill check it in the coming days
