Not a good idea. The fuel pump relay should not provide power to the fuel pump until the engine is actually running, not at ignition on. The pump should be wired to shut off if the engine stalls, or in the case of an accident where the engine stops turning. The method shown here will allow the pump to run any time the key is in the ignition position...wrong!!
@@zemoney954 Here's a couple of vid links below using a 3 terminal oil pressure switch. Both vids use the same method. It is also possible to wire the relay coil + terminal via a diode and resistor to the charge/battery lamp circuit for the alternator on most older cars. Once the engine is started and alternator starts charging, the fuel pump also runs, but it's not possible to use this method if you happen to have a one wire AC Delco alternator without a charge warning light. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tPh2Na3vbGc.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0lTXmPRxVD8.html
Unless this is some cutting-edge fuel pump with advanced 'fuel pressure safety logic' built in (which I highly doubt), it's imperative to use a mechanical oil pressure safety switch in conjunction with any setup like this if you value your car...and your life!
My 2001 Dodge. I just put a vast bump on it and what I find. When I stop the heat won't let it start again. Until it cools down, The trouble is, there's too much pressure. And AVP44 will not allow the fuel to enter. They say you can put a relay on the fuel pump. That allows your starting to turn over without the What you want is a relay that allows the motor to turn over without the pump for a second or 2. Can you show me how to hook up
Hi i was wondering if i can wire a relay to my fuel pump its a 87 corvette and they wiring is bad on it and it keeps popping fuses and it build pressure one day and then its just nothing
