Car Cranks... wont start... no fuel Pressure

[Nixem311]

Ok... luckally its not my GSX that is having the problem this time around.. but my buddies...


this has only happened since the weathers cold out...



Car mods that yall should know for this diagnosis:
Large turbo (tehehe)
VPC/ AFC combo....
255 warlbro .. and 650cc injectors...

Car has run fine with the above mods for about 6 months now...


The Problem:

Car will start... and we will drive in it for about 20-40 mins... then all the sudden .. ALWAYS AT A LIGHT OR STOP SIGN.... the car will just shutoff.. then will just CRANK AND CRANK.. but wont crank over... durring this time.... there IS SPARK... but the Fuel Pressure Guage ... reads zero durring the cranking proccess...

also ... if we wait about 5-10 mins .. the car will turn right over.. we will get 38 psi of fuel pressure @ crank.. car will crank right over.. and well b on our way ... FOR ONLY 20-40 MORE MINS .. until the process repeats again.....

• ECU
• old ecu's caps and tried the old ECU after it was repaired
• Fuel Pump Relay ( lil gold box next to ECU)

please help...

Have you done the fuel pump wire modification? IF not then do it and you wont have to worry about the computer handling the fuel pump anymore.
