i went and had it pulled it was a p0200 somthing about an electrical malfunction in the fuel injection system, anyone ever heard of this

Sounds like you got a bad Fuel Injector or a fuel injector drive has dropped out on you. Here, this should help.

DTC P0200
Circuit Description
The control module enables the appropriate fuel injector on the intake stroke for each cylinder. ignition voltage is supplied to the fuel injectors. The control module controls each fuel injector by grounding the control circuit via a solid state device called a driver. The control module monitors the status of each driver. If the control module detects an incorrect voltage for the commanded state of the driver, a fuel injector control DTC sets.

Conditions for Running the DTC
The engine speed is more than 400 RPM.
The ignition voltage is between 6-18 volts.
Conditions for Setting the DTC
The PCM detects an incorrect voltage on a fuel injector control circuit.
The condition exists for 5 seconds.
Action Taken When the DTC Sets
The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.
Conditions for Clearing the MIL/DTC
• The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.

• A current DTC, Last Test Failed, clears when the diagnostic runs and passes.

• A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.

• Clear the MIL and the DTC with a scan tool.

Diagnostic Aids
Performing the Fuel Injector Coil test may help to isolate an intermittent condition. Refer to Fuel Injector Coil Test .
For an intermittent condition, refer to Intermittent Conditions .
Test Description
The numbers below refer to the step numbers on the diagnostic table.

This step tests for voltage at the fuel injector harness connector. The INJ fuse supplies power to the coil side of the fuel injector harness connector. If the fuse is open, a short to ground on the fuel injector B+ supply circuit is indicated. The INJ fuse also supplies voltage to the ignition coils. If the fuse is open, inspect the circuits to the ignition coils for a short to ground.

This step verifies that the PCM is able to control the fuel injector. If the test lamp blinks, then the PCM and the wiring are OK.

This step tests if a ground is constantly being applied to the fuel injector.
