Hey gang, Dan here. I have a problem with my mh not starting. Here is what i have done so far. Check fuel to the carb which has a tbi closed loop system. By disconnecting the wiring at the fuel tank (plug on top) and placing 12 volts to the fuel pump side wiring the pump runs and supplies fuel to the carb but not thru the tbi. I can here the pump running for 2 seconds when switch is turned on. ( this is with the wiring plug reinstalled) I asume the fuel pump is good, the filter is good, and i also replaced the fuel relay but to no avail. Fuses show good under dash pod ecm, and inj.need help

You seem to have put a lot of effort into fuel delivery, was there something that pointed you in that direction first?

How about spark, do you have that at the plugs?

Oops, just re-read your post again. I see now you're not getting fuel at the tb. Thats pretty strange considering what you have done and seen. Have to think about this a bit more.
