Very helpful, OUTSTANDING CUSTOMER SERVICE , will recommend to anyone needing Diesel repair sFEB 20, 2021 ,EDITING REVIEW FROM EARLIER .AFTER RETRIEVING ONE OF MY CLIENT S VEHICLE S DODGE 98.5 D2500 24 VALVE TURBO DIESEL CUMMINS. I AND MY CLIENT DECIDED TO PURCHASE A USED , INJECTION PUMP TESTER SPECIFIC TO THIS MAKE ,MODELANDTYPE THE TOOL WAS I BELIEVE $500/USED CLIENT PAID,AS DID HE PAY TO HAVE A LICENSED SHOP. DIAGNOSE ITS FAILURE, TO BE THE INJECTION PUMP.?? AFTER I RECEIVED THE NECESSARY TOOL TO PERFORM THE TEST. I TESTED THE INJECTION PUMP, IT PASSED THEIR DIAGNOSES WAS ( ( INCORRECT .?!!? THEY ARE SUPPOSED TO BE THE PROFESSIONAL S IN THIS PARTICULAR FIELD, AS WELL AS HAVE THE TOOLS NECESSARY TO DO THE JOB I DO NOT DEAL WITH THIS SPECIFICALY. I WORK ON THEM IVE REPAIRED THEM BUT THERE ARE CERTAIN OBJECTS OR POINTS I CANNOT DO BECAUSE I DO NOT HAVE THE TOOLS(ESPECIALLY THE TOOLS GOING TO BE USED A COUPLE OF TIMES AND COST $500USED/1500NEW) AT THIS POINT IT IS CHEAPER TO SEND IT OUT TO SOMEBODY THAT HAS THE TOOLS AND USES THE TOOLS QUITE OFTEN !!! I AS A CERTIFIED TECHNICIAN WILL ALWAYS OUTSOURCE IF IM UNABLE TO PROPERLY DIAGNOSE DUE TO NOT HAVING THE PROPURE TOOLS . OR ABILITY DO A PROFESSIONAL JOB. So 1,250 for a used reconditioned part??? So then everybody cost another $1,200 to find out that it wasnt the injection pump it turns out to be possibility ECM itself wiring harness has been checked grounds have been cleaned extra grounds have been had and all pins connections and so forth regarding the electrical harness has been gone through and you come down to being the ECM itself this is a particular unit specific to this dodge injection pump for they made about 18 months I believe its referred to as a second generation hes also shown that the truck in 2002 was reprogrammed the ECM and the PCM through the dealership so it would apparently theyve had issues. So what is going to cost a man 4,500 to find out that you were wrong on the injection pump by the time you could have you corrected it so you can put the diagnostic you would have charged him for a pump and still wouldnt have been the pump he looked through the harnesses like Ive done and then you wouldnt find out it wasnt your connections is it being the ECM and apparently theres no place to send the ecms to have them tested so this objects on hold I would not refer to Jays performance automotive they should be kind enough God knows how many hours they I put hours and days into it looking over the same thing wires connections fuel pump pressure pickup pressure I mean the whole nine yards and sent it to them to have that tested the ECM PCM and injection pump cuz I didnt and it would not have been prudent for me to spend $500 to $1,500 to charge a man for a $300 job depending on what it was they should be prudent enough to at least refund part of the minds money I dont how many hours they wasted but they make a customer happy I thought they were professional apparently I was wrong I would not send anybody there nor will I refer anybody there by the way they like to contact me or Cindy response back to this we were more than happy to sell them the tool we use to check the pump for what we have in it well its not mine I didnt buy it so he might want what you charge him and what we started for the tool to find out it is not the injection pump we can verify this and matter of fact Ill put it on video and try to see if I can attach it to this particular review or Ill just send it to you guys to show its not the injection pump this tool isolates the injection pump from the rest of the vehicle no electrical going into it whatsoever except for through this tool those charges is solenoid inside which is a valve that opens up for fuels to get in there then what it does is gives you a low idle run and a high run. As with the diesel it does not need electricity to fire or to keep running diesel is ignited by compression so long as they diesel vehicle gets his fuel it will continue to run but with the new age the electrical solenoid fuel contro

Do YOU want to be scammed out of money and parts? THIS IS THE SHOP FOR YOU

Had our 2005 Diesel Ford F350 6.0 in for repairs and results were excellent. Taken same truck in for service and recd excellent service again. Will not take our else. Have taken our 2002 Ford Explorer in for repairs and recd excellent service again. Highly recommend this place. Justin and his crew are great.

We needed a code clear and this place charges $125 per/hr. So we figured that it wouldnt be more than an hr just to clear a code. However, this place end up charging over $250 just to clear a code for a part that we had replaced. When we picked up our truck they said it took them over 2 hrs to do the job. Really? Two hrs just to clear a code that we have told them from the beginning the part was replaced. This will be our first and last visit to this place. Dont recommended to anyone and dont be surprised if they come at you with a bigger bill.

Actually takes time to listen to you and answer your questions... Didnt act like you were bothering them.

Excellent diesel shop with great people to work with. Not sure if there is anything they wont work on here. I have seen Ford, Dodge, Chevy, Jeep and so much more. Even vehicles from the 1930s. The owner is one who wont oversell you on repairs you dont need. He will even prioritize repairs on your vehicle in case you dont have time or the means to get them done all at once.

1 year after repairs:Had the dreaded “drain plug leak” on my Excursion w/7.3 PSD. (Not a drip, it was dumping oil). Ford wanted 4K to pull engine and change the oil pan. Justin said he could fix it for about $400 with silicone and voodoo. 1 year later it’s still not leaking. Happy camper and will fix same way again whenever it starts leaking.He also changed the front end and shocks last year. Still drives like new.

Ok

Justin has been taking care of my familys cars and trucks for years. We highly recommend his business. The Cosca Family

Never had an issue. Bring my truck here for all upgrades. Justin and David are very knowledgeable and made sure all need were met. Thank you guys for the great work.

Great Group. Alot of skill in this place!

Smart, friendly, experienced. They really do all they can to help you out.

Best powerstroke shop in fresno County. Justin knows his s#%÷!!

This place like no other they worst ever. After 3 weeks and over 2 thousand dollars they left y pickup worst than when we took it to them. They absolutely suck .

Good work

He gaves us a quote to work on my GMC diesel of $4000-$4500 (not written) when I picked the truck up 2 weeks later it was $7400.... he said he did extra things ge thought I would want done... without calling me to approve it! The wiring was done extremely shotty! And part of the work wasn’t even done!!!! My advice DONT GO TO THIS SHOP. He is not ethical !!! If you do get it in writing and make sure he calls with any extras! I own a business and WOULD NEVER treat a customer this way!

Trustworthy, friendly, upfront and honest.

Awesome people that do fantastic work!

These guys rock! I will not take my truck to anyone else in the valley.

Top notch service

Fast, Friendly service

Good
