Diesel Injection Service

I recently went down to Fontana for the Nascar race. My truck broke down while I was there so I went in and spoke with the owner Donovan Marshall to see if he could help me. Donovan reassured me that he and his professional and qualified staff could help me and fix my truck in a timely manner. I am so grateful for all of the help from the Front office staff, the mechanics and from Donovan. I cannot thank them enough for helping me get my truck fixed so I could get back home safely. Sincerely, Mark Hahn

Donovan at diesel injector epair shop is honest. I will use them again because everything that he promised, he did.  That is a quality that is hard to find in any business nowadays. Based on my experience, I will gladly refer diesel injector service to anyone and I will continue to go back-and-forth to them and give them my  business.

The staff never gave us a a hard time, Natalie was extremely nice as well with Andrew. However I dropped off a diesel pump for a diag and quote on overhaul and it stayed at their location 3 business days. I called numerous times for an update and I was given the run around that theyll check it out each day. The wait period isnt what made me upset. On the 3rd day I called to see if they had dissasembled the pump and check out what it needed. I was told that there was fuel contamination within the pump and that it needed an overhaul. I then asked, you guys dissasmbled the pump and tested it out right? They told me yes. I ended up telling my customer that yes his pump was bad and that he even has contaminated fuel. He took out his fuel to find out it wasnt even contaminated. It was extremely embarrassing from my part. I would have still understood if they had been honest with me and told me they had a bunch of work and have not yet gotten their hands on it. I would have forwarded that to my customer and tell him we still had to wait. My customer went to go get the pump and it was not dissasembled. Reply: it was under Mikes Diesel service
