Your safc may of went bad, try unplugging it to see if that makes a difference. Your pump is priming but is your fuel filter clogged?(check for wet plugs also.) check all your intercooler couplers as well. Unfortunately rb engines are a pain so I'd check the ignitor and cas to be sure.

Im pretty sure fuel its gettin to the fuel rail cause i removed the hose that comes from the fuel filter to fuel rail and was shooting fuel when i turn key to on position.
Also theres a weird
Noise on the egi relay when i try to start the car

Sideways_blksr20 · 07-25-2011, 12:30 AM

Btw i put somegason the air filter and the car starts for few seconds

Sileighty_85 · 07-25-2011, 08:04 AM

well if your getting only 1v on the fuel injectors, then you need trace that system to find out why

Sideways_blksr20 · 07-25-2011, 10:41 AM

But what about the egi relay is it suppose to make that noise

Sileighty_85 · 07-25-2011, 10:43 AM

Sounds like bad wiring, id pull the harness and inspect it.

Sideways_blksr20 · 07-25-2011, 12:25 PM

I tried disconnecting the safc and still wont turn on

Sileighty_85 · 07-29-2011, 01:11 PM

you cant just disconnect it, you have to wire it back to stock as well as installing the stock Fuel Inj and MAFS

Sideways_blksr20 · 07-31-2011, 12:12 AM

Problem solved. One of the wires from the chassis harness wasnt getting 12v
