I finally received my fuel injectors back from Rich at www.cruzinperformance.com and reinstalled them. The truck runs better than it ever has while I've owned it. It has 155k miles on it by the way. It was $98 including shipping to get the injectors serviced and it was worth every penny. Rich sent me before cleaning/after cleaning on the injectors, and I was (sorta) suprised to see that one of my injectors was only running about 20% of the other injectors. This was the source of my roughness in the truck. Now that they're back in, no big problems! Just thought I'd share, as Paul did when he had his fixed. | ||

Jared, could you list the errors the truck displayed prior to your having the injectors serviced and what the repair company did to cure the sick injectors. mike w | ||

Jared: Hate to do this to you, but, was Rich wearing a mask and pointing a gun at you when he quoted you that price? Most any diesel repair shop can do it for you. Glad it worked so well for you, mine merely made the weak fuel pump more apparent. Mileage nearly doubled though. | ||

Paul, I called the 3 diesel repair shops in town that were listed in the phone book, and none of them would work on petrol injectors. I also heard these were "bosch" type injectors, so I found a Bosch Certified repair place in town, and they also said "we can give it a shot, we have the equipment but we havnt done them". I felt safest just sending them to Rich and having him do the work. I also contacted the dealership and a few import shops in town, and every single one laughed at me and said "You should just replace the injectors". I figured $11 per injector was cheaper than $60 for a new one. M.K. I was having problems with my fuel system, and I had everything fixed. It was the pressure regulator that needed to be replaced. Then my alternator went out, and after I replaced that I took it into town, and it was running like crap. I had a check engine light, and it threw up a code for Fault in Injector Bank A. I think I know why it threw the code. In my hassle with an erratic idle (a problem that came up between the fuel/alternator issues), I took it to an import shop, which hooked it up to a machine that ran fuel cleaner through the system. A few days after I got the truck back I had this Fault in Injector Bank A code. I dont think it was coincidence either. Go here to see what he did for me: http://www.cruzinperformance.com/injsteps.html It runs great, I'll have to take notice of the mileage, but I honestly think I'm getting a better MPG. New Pump/Regulator/Clean Injectors should help. | ||

$11/injector for the process described on that page sounds like a steal to me, and I'm always a sucker for anyone with a full-disclosing webpage. Thanks for the reference Jared, I'm going to keep that link handy. | ||

How difficult is it to remove the injectors? | ||

Professional magic prohibits me from divulging how much I pay for injector cleaning, but it is a fraction of that amount. Glad you got them cleaned and they work for you. As for difficutly in removal, it isn't very difficult, just time consuming. You must remove everything on top of the manifold to get to them, then pry them out, pop on new O-rings, give a shot of silicone and pop em back in. Make sure to flush the fuel rail really wella sthat seems to be where the crud builds up. Peace, Paul | ||

Yeah, you have to remove the plenum cover, and the ram housing(which is below the plenum cover). This is pretty easy. You also need to remove the kickdown cable and the throttle cable from the throttle assembly if you want to remove the plenum cover from the engine. This isnt very hard, just make sure you put the stuff in zip-loc bags and label it all. The most time consuming part(read: frustrating) would be removing the little springy clips that hold the fuel injector electronics cable onto the top of the fuel injector. You need to remove all of these, unbolt the fuel rail(and the return/supply) then pull it out. I had some trouble getting the fuel rail out, it just didnt want to budge, but some patience got it out. I cleaned the fuel rail really well, and also disconnected the fuel supply line at the fuel filter, held up an empty bottle, and had someone blow shop air through that section of the fuel line, since it obviously doesnt have a filter before it hits the rails. The rail was very rusty, the supply line wasnt really that bad, I could only notice a slight red coloration of the papertowel I held up after the fuel was all gone. Good luck. | ||

I took my injectors into a Bosch diesel service center. They cleaned and tested for around $40. They should all flow within a 7% range of each other. Mine were 15% +/-. They all sucked. Bought new ones for around $40 - included seals. The other thing - often overlooked - is the wiring harness connecters themselves. Check the condition of the pin connectors inside. 4 of mine are rusted and need to be replaced. I got replacement connectors from a L.R. shop in L.A. $5 ea. | ||

I filled up again today since I was near the gas station, and I went 215 miles on 11.5 gallons of gas with the clean injectors, so that averages out to about 19 mpg, and all that driving was in the city. So I went from about 14->19 mpg in the city. I'll have to wait a while to see how I do highway driving, since I wont be doing too much of that till August. Just thought I'd let ya know. By the way I have a new fuel pump and a new pressure regulator. |
