Hey all,
Car has a gen4 engine swap fueled by a 550cc Supra fuel pump. This setup ran fine on the old stock 440cc pump (stock boost), and once i upgraded to the Supra pump it also ran fine for several months on stock boost.
Recently the fuel pump relay blew (car just shut off while driving) and I had it replaced but then it did the same thing again and my mechanic is saying that the second relay has also blown. Their theory is the upgraded pump is blowing the relay and want to try putting in a stronger relay.
Any thoughts on what might be causing the relay to blow? Anything else to check? Seems strange that it ran fine for months but now can only go a day or two before blowing the FP relay again.
Thanks!
