[v8etr]

My injectors are dumping fuel in mt 87tr, I have checked the cam sensor, crank sensor, fuel pressure, I put a noid light on the injector harness, I have no more ideas Please help.
Thanks

As was stated on the other board: What exactly do you mean by dumping fuel, and what symptoms lead you to this conclusion.


Also, a lot more data on your setup would help!!

Like Dave said, what makes you think they're dumping fuel?
What did the noid do?.
Do you have a fuel pressure tester?.

all of the plugs were fuel soaked. and it wouldn't start. I changed the plugs and it started up with a miss and it wal billowing black smoke out the exhaust.

my set up is a stock block, gn1 heads, 218 cam,55# injectors modded computer, precision stealth turbo,reds double pumper with caspers hotwire kit, precision front mout intercooler,smc kit, 3 inch down pipe, accufab adj. regulator, I know there's more.

the noid light blinked .and the fuel pressure is set at 40psi (I have also tried 30psi)

Thanks

How did you set the FP? Was the engine running??
look to see if both pumps are on at idle...
I seriously doubt all 6 injs are fubar.
Were they new or used? If used, did they sit open for a period of time?
Is this a new build, or has the engine been run prior to the problem??
What are your scan tool readings? You DO have one, right?? :str:

[tweaked]

Is the installation fresh? [Just installed or did it suddenly die?]

Did you put a scanner on it to ck for codes & values?
What is fuel pressure?

Pls Check or swap the following:

ground wires at rr of head
alternator voltage
battery cables & ground
ohm resistance from block to firewall < 1 ohm
ck MAF
shorted injector harness [particularly aroung EGR]
coilpack & module
ecm
O2

Good luck and keep us posted.

Have a nice day.

the ground wires at the back of the head are in decent shape
The positive battery cable is in bad shape (but no bare wire showing)
the negetive cable is in good shape
the engine grounds are in good shape ( I have added an extra)
I will check the ohm resistance from the firewall to block
maf I will try to find a known good one to replace it with
The injector harness is in good shape
I have replaced coilpack and the module
How can I test the ecm??
could the o2 cause a problem like this?
(I am new to the buick scene)
I have an otc 2000 scan tool and it doesn't show any codes
I will let yall know tommorow how everything works out.
and it happen all of a sudden i put about 300 miles on it
Thanks

My vote goes to the double pumper. Disconnect the second pump and see what happens

I finally got the car started!!!!!!!! :rock:
I pulled the computer out and both of the chips and cleaned everything with alcohol and made sure all of wiring was in good order. and it then started.
It still runs pretty rich. Any ideas on that???
Thanks
