Problem after installing Heads, Cam, DoubleR, FAST102 Greetins from Chiapas Mexico, currently we are upgrading a Camaro LS1 1998 with the next setup:
- Precision Race Components Stg. 2.5 LQ9/6.0L Heads & Cam Package
- PRC 675 EHT Dual Valvespring Kit
- Comp Cams Magic Stick 4
- 114 LSA
- Pushrod 7.425
- RollMaster LS2 Double Roller 11-1185
- Texas Speed Ported LS6 oil Pump
- Racetronix Fuel Pump
- Aeromotive FPR
Our currently setup looks like this:
The engine starts correctly just ONE time, then it shuts off after 10 seconds more less of running, as soon as we try to turn it on again, it cranks, theres fuel pressure running at 43-48 psi, theres injector pulse, but it DOESNT start.
If you take the spark plugs out theyre smoked black and with tons of fuel on them.
Is there anything wrong with our setup? Is there any posibility that this is because we havent reprogramed it yet? If we take the spark plugs out, clean em, get all the fuel of the cylinders out, it starts but it shuts off again.
We are running stock injectors, already test em on my Injecto LAB, and theyre working fine. Any doubts or ideas?
Thanks a lot guys, were on Chiapas Mexico, the last state in this country where nobody knows ANYTHING about this stuff.

I do agree that it needs a tune, but you say you have kept the stock injectors and just swapped the pump out. the car should still run without a tune. You sure you installed the timing set correctly? maybe it is advanced too much.

The timing chain is set at 0 degrees as it was originally, I personally installed the double roller in the shop without any problems.
Actually fuel pump is sending 60 PSI directly, but with the Aeromotive FPR we can adjust it in the range from 20-60, we put it on 46 cause is what the stock injectors were working on, fuel pressure regulator is working fine.
The setup is this, with the difference that we are running the stock tank gas, not a fuel cell, originaly this system was returnless but with route a line to the tank as a return line.
Thanks a lot for your support.
