Re: why do my new injectors leak down quickly
How do you know for sure that it's the injectors? It could be the fuel pump or plumbing. Did you put a new fuel filter in? Is there any possibility you got dust or dirt into the injectors during the install?

Re: why do my new injectors leak down quickly
Is there yellow or silver/white accel injectors.. My Accel injectors (yellow) seems to be bad, (not all of them but some...)
I think I will buy new ones, Ford Racing injectors instead..
You can try and see if its the pump / or injectors / regulator..
Sqeeze the return hoose and see if the pressure holds.. if it holds your regulator or injectors are bad..
If you sqeeze the input after shutting of the ignition and the pressure holds its the pump, (f you remove the clamp and the pressure drops its going back thru the pump..)
If you start the car and remove the vacuumhose from the regulator, if it comes out fuel its bad.. you need to change the regulator.. if not, there may be your injectors that are bad..

Re: why do my new injectors leak down quickly
jeff the only reason that bosch injectors are not in you car is because of the contract with rochester products,, gm had to use that crap multec injector.. 85-88 had bosch in them.. then in 97 they went back to bosch.. now delphi has the contract.. the bosch work great in our engines
