LB7 FICM Mail-In Evaluation

2001–2003 GM Duramax

What This Is

This is a mail-in evaluation for your LB7 Fuel Injection Control Module.

There is no upfront repair charge.

You send us your module.
We inspect it, test it, and tell you exactly what it needs — if anything.

No guessing. No pre-pricing based on a story. We work from the module itself.

Repair Pricing

Most LB7 FICM repairs fall between $516 and $750, depending on internal condition.

Final pricing is determined after inspection and testing.

You’ll receive a clear quote before any repair work proceeds.

Same-Day Evaluation & Repair

In most cases, evaluation and repair are completed the same day your module arrives.

If the module is approved for repair and no unusual complications are found, we work through inspection, repair, and verification without unnecessary delay.

If something outside the ordinary is discovered, we’ll contact you before proceeding.

We don’t let modules sit on a shelf.

We Don’t Just Repair Boards — We Understand the Truck

A lot of companies can work on a circuit board.

Very few understand the LB7 system as a whole.

We work with these trucks regularly. We understand how FICM issues present, how codes relate to internal failure patterns, and when a module is actually the problem — and when it isn’t.

We don’t stop at bench testing.

We verify repairs in dedicated LB7 test trucks under real operating conditions. That means live scan-tool data, voltage verification, and real-world function — not just a powered-up board on a bench.

If it leaves here, it’s been tested in a running truck.

Not Sure If It’s the FICM?

Call us before you ship it.

If your symptoms or codes don’t point toward the module, we’ll tell you.

If it makes sense to send it in, we’ll tell you that too.

You don’t need to bounce between shops guessing. We can help you think it through before you spend time and money shipping parts around.

How We Evaluate Modules

When your module arrives, we:

• Document its condition on arrival
• Perform internal inspection and analysis
• Run structured bench diagnostics
• Repair as required (with your approval)
• Verify operation in a dedicated LB7 test truck
• Confirm proper function with scan-tool data

When appropriate, we may document testing with photos or video.

We eliminate guesswork before it goes back in your truck.

Repair Pricing

Every module is different.

Preventative service and failure-level repairs are not the same thing, and pricing reflects that.

Most work falls within a predictable range, but final pricing is determined only after physical inspection and testing.

You will always receive a clear quote before any repair work is completed.

No approval, no repair.

A Few Important Notes

• This is not a flat-rate repair
• This is not an exchange program
• Some modules are repairable, some are not — inspection determines that

If you want a careful, properly verified repair process backed by real-world testing in an actual LB7 truck, you’re in the right place.
