I need to know what fuel pressure is required for a 7.4L TBI. I don't get any codes, but it won't idle when cold and won't stay running long enough to warm up. I have replaced the fuel injectors, diaphram, ICV and ICU. I have 13PSI at the fuel line into the TBI. I have tried adjusting the throttle plates to no avail. Any ideas?
