Fuel cut or bad ecu signal?
 
My frs has about 8000 miles on it and I just had the fuel pump changed to get get rid of those nasty crickets for a bit, this is not even a week later and last night after I got back from club loose I decided to have some fun at my secret spot. Not even 10 secs into drifting car lost power and gripped up and while I was slowing down it completely stalled. Few cranks and got nothing and have it the oh shit car is going to leave me stranded again. Turned the key completely off and cranked it and luckily it started but the idle was dipping, I pulled away and the car kept puttering in every gear for about 2 mins.

Not sure if anyone else has seen this issue but I figured maybe fuel cut if the fuel pump was installed wrong, maybe just a bad signal from the ecu, or oil temps were high from hour ride and the drifting put the temp to a point of going into limp mode.

Please anyone chime in if they have an idea because I am in no way ready to start with bs this early on.

How much fuel was in your tank. Doing donuts with not enough fuel could starve the fuel sender.

I had 1 last week when my car wouldn't start saying low pressure in the fuel rail, I had brought it to Toyota and they couldn't find the issue and just replaced the fuel pump to get rid of my crickets

Whats the code?

These cars do have fuel starvation issue below half tank but that only was the rule for boosted cars. The fuel pick up is on driver side. In the middle of tank is a large hump

were you low on fuel then that code popped up?

1/4 tank I would say you were just too low on fuel to be slinging the ass around and starved the pump.. The ecu will act up if you spin the car even in asc off mode (not the pedal dance, but can still go into ice mode even with the pedal dance)...

However, the fact that you got a low rail pressure code a week before this.... that is a little suspicious and seem too much of a coincidence to me.

So as long as I keep the fuel above a half tank I shouldn't have this problem again?
