Fuel system not working properly.

Fuel Injector Replacement $400.56 - $3968.30 Get a Quote

You have already performed most of the repairs associated with this problem. This vehicle uses throttle body injection (TBI) which is a fairly simple system. In your situation, the pressure line to the throttle body assembly may be obstructed or the fuel meter/regulator may be faulty. Also, you said "no fuel is getting to the injectors". But, if you really mean no fuel is coming out of the injectors the problem may be that the control module is not commanding the injector on. Also, the injector itself may be to blame. It sounds like you have already replaced a lot of unnecessary parts, so my suggestion is to take your vehicle to a trained professional for further diagnosis, such as the ones at YourMechanic.
