pump relay probably stuck
failed relay
I believe this usually this happens if the fuel / air mixture is not rich enough (too much air / too little fuel) which causes the cylinder heads to get too hot which means that any unburnt fuel in the cylinders will continue to ignite even after the ignition has been cut.
Could be to switch the fuel pump on/off when ignition is turned on or maybe for the starter motor?
Need to replace fuel pump relay.
Fuel pressure (ignition key turned to on, engine not running): 50 to 60 psi
there is always fuel pressure even the car is on or not, u will need to release fuel pressure before doing any thing in the fuel line
yes, there should be power if key is on
is not electrical,is from fuel shutoff is why
what kind of car? IF its fuel injected the key turns off the computer, the fuel pump, and the ignition coil
