Fuel Delivery issue
 

Hi Guys,

I have and 87 TII and I'm at a roadblock with it. I have tried damn near everything to figure out what wrong with the car but other heads can always help. anyway to the issue at hand the car starts up and idle fine but when you try to mash the throttle (sorry for description) the injectors start sounding like there is not enough fuel coming out. On the other hand if i slowly creep up to the higher rpms it sounds ok but aroun4500-5000 rpm it start the delivery issue again. I have checked them pump, changed the fuel pump, changed injectors, replaced fuel filter, replaced manifold, replaced fuel lines and regulators, tried a different computer. I'm at a loss as to what the problem could be. Also when you hear the fuel pump kick on the lines almost sound like theres pop rocks in them. Any help suggestions or ideas would be greatly appreciated.

Make sure the TPS is plugged in.

Check that the TPS has a smooth resistance change throughout its entire sweep.

Tried that and also replaced tps just in case..still the same thing..thanks for the advice though

Have you tried rewiring the fuel pump?

i have not tried that i have checked to make sure it was providing the right amount of pressure but never rewired
