Quirky 740-T

My bad- sorry, a bit preoccupied today! Here's the original reply by "porkface":

check the green wire at the injector for power with a digital meter, should be the same as the battery. no power-back up to the radio relay and try again. if the relay gets power but won't pass power, replace it with the cooling fan relay and try again. if the injector has power on the green side, go to the gray wire-should still have power until you crank it. then the ecu will pulse a ground on the gray wire to fire the injector. no pulse on the gray wire, back up all the connectors to the ecu and make sure there's not a problem in the harness, connectors, etc.

if the fuel system checks out, the look at the ignition system-cap, rotor, etc. a weak coil can fire ether but not gasoline. good luck, chuck.



We've tried most of that but my other half is thinking the problem may lie somewhere between the tank and engine comp. Just hoping for some more ideas.
