Did you get any response from Ivey?

he probably rescaled the stock sensors which should work fine. you really need to start checking things like fuel pressure and buy a cheap ($20) multi meter to get this figured out. there are so many things it could be and it we cant rule out some things it will never get solved. just knowing if there is or isnt proper fuel pressure dramatically helps narrow it down.

I've been using the multimeter to check the sensors. I'll probably go buy a fuel pressure to check to see if there's enough pressue pushing the gas out. Again, I've take the injectors out and tried starting it, no fuel coming out of them. Then one of injectors fell off (more like blew off) and fuel squirted everyone. Whether the car is acting up or if it's driving fine, i can not hear the fuel being prime. Ive even sat in the back, hand over the top of the fuel pumps and can't feel fuel being sucked into the lines at all. I do hear fuel being sucked back when they car is turned off.

Another note: I've not heard the car prime once until today. I was messing with the positive and decided to retighten the red wire from the buschur double fuel pump. Went back and started the car and heard it prime. I was like, hmmm, never heard it prime before. Went back and took off the red wire from the positive. Went back and started the car, no prime but the car started anyways. Here's the odd thing though, went back and retighten the red wire and tried priming but it did not prime. A little bit later (haven't touched the car from the last time), it primes. So I don't know why it primes and why it doesn't. Also, what's purpose of that red wire anyways? Does it control one of the pumps? Am I suppose to hear it prime? You can hear the pump once it starts as well.

Update/Resolution

turns out, car was not holding pressure (double fuel pump). shop was able to fix this.

How did u make it hold pressure, Im on e85, speed density, and I have the double pumper, and I have the exact same problem. At cold it starts but afte r I turn the car off, I have to wait hours before I can start it. Was it a sensor?

i dont believe it was a sensor but.... i did replace the map sensor with a jdm one i think. its been a while. but it was done while we removed the vpro since no one close to me could tune it and went back to tuning the stock ecu. i do not believe we swaitched out the double pump, lines, fuel rails, injectors, resistor box.

hopefully this helps

Basically I’m having the same issue only different is that when the engine is warm up car cranks but won’t turn on and engine start shaking really bad😞
I been changing parts and still same issue
gear cam and timing chain (done)
crankshaft sensor (done) and I’m still having the same issue 🙄 any idea what this could be ?
