do you have power @ the secondary injectors?

They have power. Colin, I've swapped the ecu/boost sensor/afm...

Ahh sorry I overlooked that.



Tough situation!

Well with Camel's help I did some backprobing. Tps/cas/injs/water/air temps sensors are all giving the correct voltage to the ecu.

if it its not injectors or ground.. then the ecu is blown... remove the passenger side carpet.. then take off the ecu plugs.. and smell where the plugs go.. if it smells burnt then its a bad ecu... but then the problem is.. how did it blow.. maybe u have a short somewhere.. the reason im saying this is because.. ive seen some many 3800 rpm hesitation problems .. its not even funny... if it feels like it hits a brick wall.. then u can eliminate the fuel filter... fpr.. coils.. cas... injectors...or pressure sensor...i think its the ecu....

Just installed a new walbro fuel pump/intank filter. Old one was not clogged. Problem is still not fixed. The outer fuel filter was replaced before I got he car, I can see new hose/clamps on it too so I know its been replaced.
