Thanks
Looks like your motor uses a vapor separation tank
VST
Not real familiar with your motor but find the VST and look for a schrader valve (bicycle tire fitting) which will have a plastic cap on it.
Find/rent a fuel pressure gauge and attach to it. Then run the motor and watch the pressure to see if it falls off. I'm guessing the pressure is dropping off or the VST is not staying full
Your motor has a
TFI system which feeds the injectors. The fitting might be on it
The ECM will have a connector next to it, which a scanner can be attached to see if there are any codes
Are you hearing any beeps?
