Hi,
I bought the twin set up for my car but after installation my car is not cranking!

When I turn the ignition it doesn't crank but the battery and fan is turned on!


Any reasons? Also is there somewhere I can see the diagram to do the installation.

Thanks

 

It sounds like you wired them Wrong.

 

Got it wired and it was a faulty starter.

Now am running too rich! Would need a tune soon.

Do you know if I need a fuel pressure gauge and fuel regulator to monitor the flow of fuel?

 

If using two wally 255 lph pumps, then no a fpr is not needed. The tune should take care of the car running rich and the second pump should only come on when it is needed. (ie higher rpm and boost)
