It seems that every since I changed my injectors and delivery valves my truck takes a long time to start. If you touch the accel pedal when you turn the key it fires right up but with heavy black smoke. Any ideas on what I may of done wrong? What will it help to change the timing? Right now when I stand on it, by the time it hits overdrive the pyro is hunting for more numbers(1500) and it is blowing pretty heavy black smoke. Boost gets to about 38psi under same conditions. Any help with any of these questions or any ideas to make the truck more useable? The fuel plates on Ebay for 30 bucks, any body got one, worth it are just by the name brand one?

 

Re; hard start, I went thru the same thing, new injectors and hard to start, after numerous hours of racking my brains, pulled injectors, tested and found 2 were bad, replaced with a new set and now starts good as new.

 

I don't think it is injectors because I'm not losing fuel prime, but I will recheck. Thanks for the advice.

 

injectors and delivery valves with a prettymuch stock turbo might be your egt problem. cut back on the fuel using stock dv's or moving the plate back. having to touch the pedal to start isnt uncommon for bigger injectors.

 

I was wondering about putting the stock fuel plate back in and keeping the dv's. would that work. Also I do need a bigger charger but don't have the money laying around for the one I won't. What would be a good (cheaper) choice?

 

You need a little more fuel to start it so just turn your idle bolt up a little and it should fire up just fine. It's on the back of the pump and it is pointing vertically with a jam nut on it.

 

I already idled it up some because after installing the injector and dv's it loped real bad and when the a/c was on and you cut the throttle real quick it would die. it idles at about 950rpm right now. still need to go more?

 

stock dv's would be your best bet. the fuel plate doesnt have anything to do with idle.

 

On my 12 vavle, I also have to hit the skinny pedal to start it up. All it needs is a tap. I wouldn't worry about it too much. You could turn your idle up, but then your idle will be even higher. If I remember correctly, your idle should be around 750 with the A/C on and in drive. That way your truck won't die on you at a stop light.

 

Thanks for all the input from everybody, hopefully will have a chance to tune on the old truck this weekend if there is no rain. Will post back about any changes, also stay tuned for the next thread will it be about turbo or trans(hmm)
