Stage 2+ is for cars with HPFP with B58TU, do you have such a modification?

I was before but I needed a new bumper so it's been parked for almost a week know I tried starting it today and on the e30 tune the pump was ticking too loud so my mechanic told me to flash back to 93 after I did that the car wouldn't start

Im not sure if its possible to damage the fuel pump running stage 2 softwear, E30 Does go off but not a week quick, i wouldnt of though that would of made the fuel pump louder but i guess could do if its gum'd up.

Just to be doubly clear here, you drove around with Stage 2 E30 (not stage 2+ E30) Sorta driving??

You should only be running the Stage 2+ maps with a upgraded HPFP, i wouldnt of thought damage would occor unless you were doing some hard pulls but maybe someone who has more experiance will hopefully chime in.

Edit - The codes defo point to a fuel issue, assuming you have checked for leaks around the pump.

Yes i see that but your first post isnt very clear,

Was the Stage 2 E30 actually Stage 2+ E30 ? And going to assume Stage 2+ is Stage 2+ 93

Need to know exactly what you were running if anyone over the forum is to try and understand and help.

You edited the post after my reply.

Errors from low fuel pressure, either a leak or the HPFP is defective.

sounds like it could be a failed lpfp if the car won't start. Do you hear it prime when you open the door

So probably either a leak or a bad pump (low pressure in tank)
