So I'm driving home tonight and started to pull on traffic. Around 5k rpm I hit what felt like fuel cut and then lost all throttle response. The only thing that kept the car running was having it in gear. I pulled it over and it's just cranking and sometimes will attempt to start but only for a second and still no throttle response. My fpr gauge is reading no pressure. I used my logger to try to prime my fuel pump and I can hear all the relays clicking but no pump running when i prime it with the logger. It's a Walboro 255 btw. The fuses all looked good and I put gas in it 2days ago. I'm assuming the pump has died on me but wanted to get a second opinion before I ordered another one
 
Always go back to the last thing you did. In other words open up the back of the car and go over the wireing with a fine tooth comb. Make sure none of the wires pulled loose and all the grounds are intact and by the way did you rewire the pump with an additonal relay?

Also make sure the fuel line is conected in the tank.

Good luck with the spark chasing.
 
Okay so heres a new twist to this little problem. I went to meet the flatbed guy so i could get it towed to my shop instead of leaving it sit outside all night and the damn thing fired right up like nothing was wrong? I drove it onto the flatbed even. I've had it do this to me before but it usually started back up withing a few minutes of sitting. This time it sat for over an hour before starting so something is definitely wrong with it. The last time it did this I swapped the main fuel pump relay next to the ecu. It seemed to fix it for a week or so and it did this a few more times. It's now been several months since it did this last but it's back again and getting worse.

I'm going to undo the hardwire setup and go back to the factory pump wiring and see if it changes anything.I've had it hard wired for more than a year now. Maybe the relay is getting overheated from the added power draw when running full throttle and shutting off. If this doesn't fix it I'm out of ideas other than changing the pump. Whatever it is it seems to have something to do with my fuel pump or pump wiring.
 
check the walbrho site i just found out somewhere that they have a recalll on some of the pump and it sounded like they were reported to do the same thing your was doing
