new delco distributor
new coil
new wires
new harness from PFI
new fuel pump 8112
7747 computer
new pigtail for 2" TBI iac
So basically I take and put my timing at 8degrees btdc and turn my fpr up to 30 psi
all should be good.
The ecm is actually inside of a fiberglass box.
As far as ecm controlling I believe it is.
It appears to jump around.
Is is there a way to verify it.
I have disconnected the set timing...
I am lost. Just did a full swap in a boat and everything runs great.
Doing swap wan on my sand rail idles and revs great in park but no power in gear.
Basically this his is what I have.
...
Ok just a good ole update. And maybe it will help a few ppl.
The normal small block Chevy loves 12-13# fuel pressure
The vortec series requires 26-30# of fuel pressure.
So if you switch heads...
No I have a modified boat chip for my 7747.
Also little more info.
My tbi has a modified FPR. I have it set at 20 psi and it still doesn't want to run. But as soon as I block return then it...
Ok she is alive and running.
BUT, and there is always a but.
I kept omitting the fuel pump.
The fuel pump is a SP1175 12-26#'s pressure with 50 to 58 gph
Even tho I was getting 13#...
Ok as of now this is what I have found out.
Motor will run while spraying starting fluid.
during this running the injectors are pulsing
Installed a electronic fuel pressure gauge
During start...
ok so after removing the injector connectors and having my daughter crank the engine I was able to keep engine running for about 20 or 30 seconds.
Didn't want to run much longer do to no water...
Have not tried that. I will try that this evening when I get off work.
Basically ly all I do is remove injector connectors and spray and start and continue to spray a little to keep running.
...
It holds 15 lbs for about 30-45 seconds after it dies
OK here is what has happened so far.
Noid Light hooked up and while cranking and attempting to run lights flash.
Ignition on coil voltage is 12.96
Coil while cranking 11.84
Removed one...
The harness is from PFIsys.com.
I I do not have a noid light. But I can check to see if I can find one.
But on the other hand.
I have replaced the faulty pickup coil actually just replaced the whole the distributor.
I have increased the time of running from 2-3 seconds to about 5-7 seconds.
...
90% of All GM V4 V6 V8 turn Clock Wise and so does the Distributor
The engine that I have is a counter rotating motor. It has a gear to gear timing. With the gear to gear timing the only direction...
Yes I have hook scanner up and no codes.
Test 1 is the use of AC voltage.
Also I had an extra ICM have already switch it out and still the same issue. Which lead me to believe the pick up coil.
Which lead me to checking it and coming up...
I understand there is three test that you can do with a pick-up coil.
Test 1.
Use multi-meter to for the voltage being delivered to ICM should be between .3 and 1.5 volts AC
hook up positive and...
Please explain. The only reason why engine is reverse rotation is due to the gear to gear timing. The engine doesn't use a timing chain.
Distributor is turning in clockwise direction with firing...
Well I was able to get out on for a few minutes today.
I checked all the preliminary voltage into the ICM.
I disconnected the Pick-up coil which I do believe to be bad.
I was reading in one of my...
I was just reading a similar scenario on internet.
They said in that one that ICM was cutting ties to the fuel injectors.
We investigate tomorrow
The thing is I have bypassed the power on the Relays to gain constant power on fuel and tried cranking and starting to see if it was the fuel or electrical. Even with constant fuel pump it still dies...
