Just saw your info on the voltage. Would you have any idea why it would be so low? I rechecked it as you said. One side I get no reading and the other I get 3.60 volts. If it is a ground, where should I start looking? So far I've replaced the external in line fuel filter, injector (which I took off and put old one back on b/c it did exact same thing) blew out return line and all ports on TB. I found a used TB complete on eBay and ordered it and am just waiting for it to install. But if its voltage issue I don't know where to look. Thank you for any knowledge you can instill on me to solve this.
I checked the voltage on the throttle body injector and when grounded to frame get a 3.6 reading with only ignition on not running. When I check across injector connection I get 3.57. Can I run a 12v feed from ignition and splice into injector connection?
