GM Part Number = 97303751

*** Currently we do not have exchange units available.  We can offer to rebuild yours.  The price is $697.70 plus the shipping back to you.  If yours is not rebuildable, we will ship it back to you at your expense if you choose.  The rebuilding process takes 12 business days from the time we get it.  Call with any questions.  Thank you! ***

The FICM is the Fuel Injector Control Module that sends the signal to the injector to open or close.  Bosch refers to it as an ECU.

This is a remanufactured unit that has a one-year parts-only warranty.

Due to the high number of bad cores we received back, we are out of exchange units.  We can have your FICM rebuilt, but it takes approximately two weeks for the turn-around time.  Thank you.


Core Charge Instructions

Click on the drop-down list to add or remove the core charge.  To avoid paying core charges, a matching core must be received prior to the exchange part being sent out.  We will send out the part before we receive the core if the core charge was applied.  That core charge will be refunded 100% if an acceptable, matching core is returned within thirty days of purchase.  The most common reason for a core being deemed not acceptable is water damage.  Testing to see if the core is acceptable takes up to 10 days from receipt.


If we do not have this part in stock, or it shows on back order, don’t worry. Huckstorf Diesel receives shipments from our suppliers daily. We also have the ability to get parts drop-shipped directly to you from the closest warehouse or the manufacturer. We are also able to source scarce products nationwide and globally quickly. Let us help you find those hard to find parts.
