I was quoted 6 grand for new injectors for my 2002 Duramax is that to much?

$6000 does sound high. However, I don't know the going injector replacement in California on a first generation LB7 Duramax but here in West Michigan the only cost I've heard of was $5200 for all 8 injectors replaced at the GM dealership. This was last Fall and may still be valid. The LB7 cost is higher than the later generation LLY engine (started in January 2004 and was labeled a 2004.5 mid year change) because the LB7 injectors are harder to get at (buried) and require more parts removal which means more labor hours for the repair. The LLY replacement of all 8 injectors I'd heard mentioned was $4600 at the same dealership. Possibly, a reputable and knowledgeable about injector replacement private owned repair business may be able to quote a little lower total price as their hourly labor rate is usually less.Just wondering, how many miles on your 2002 as it's 15 years old now?

For brand new, not rebuilt, and installed, that isn't out of line.Avoid rebuilt injectors unless your dumping the truck soon.

New injectors for a 2002 LB7 engine is about $2300 dollars (parts only) plus $1200 for the core charge which is refundable. Remanufactured injectors run about $1600 dollars (parts only) plus the core charge. The rest of the $6000 would be for installation. Since you need to pull the rocker covers on a LB7 the rest of the dollars ($3700) is labor. Get a detailed listing of the charges and make a decision to see if the charges are in line with this. Bottom line, its probably not too far off on price.

We had all 8 replaces on an '01 GMC truck at work. The cost was $3,800 from an independent shop. I don't remember if the injectors were brand new or rebuilt. We also got a quote from a dealer and they were higher. I think maybe around $4,500 to $5,000.You're quote of $6,000 sure does sound high.
