I have an 02 4Runner that I just put the supercharger on. I am trying to start it and it just cranks. I verified I reconnected all the electrical connections on the engine with the exception of the fuel pump. It is disconnected so I can de pressurize the fuel system to install my URD 7th injector system.

The drive by wire throttle assembly is also making a constant noise from the back side now.

One thing I'm curious about is I installed jk22 NGK spark plugs gapped to .043". The parts store did not have Nippin Denso. The NGKs are single electrode. Could this be my problem?

 

Update, got it running. I had to plug back in the 5wire fuel pump connector. I can leave the 3 wire off and it keeps running.

Now I want to install my 190 fuel pump and 7th injector. But I cannot start the car using the instructions from URD. Their instructions tell me to unplug those connectors and start the truck and let it run out of fuel.

Maybe this is a 2002 specific issue.

Any other way to de-pressurize?

 

Just crack the line open. Not too much fuel will come out.

 

Thanks that did it! I thought it was going to spray everywhere.
