My engine won't run
I need some help with a 1994 Allegro Bus. We're trying to start the engine and not having any luck. The engine cranks over fine but no start. It has not been started in several months. It has run ...

IF you had such a thing as a stuck fuel solenoid it would either be open or closed, it would not close when removing power if it was open when applying power if it did then its not stuck
IF the engine actually ran when holding in the crank position and dies when key released then you have a faulty ignition wire or switch system
From what I read, the fuel solenoid actually has two power wires going to it. One is a higher power to initially open the solenoid while the key is in the crank position and the other is lower powered to hold the solenoid open in the run position. I'm sure you're right about it not being stuck but what if the solenoid was not getting power after it cranked. The higher power wire gets power when cranking but when the key is released the lower power wire is supposed to take over holding it open. No power to that wire would allow it to close. Does that make sense???
