Hope someone can help with this. '99 Dodge ram diesel that has an intermittent no start issue. It seems to be a lack of fuel to the injectors, but can't figure out why. If it was an older model i'd say the shut off solinoid was bad, but these don't have the shut of solinoid on them, the ecm does it... Anyway, started fine yesterday morning, but not in the afternoon... and no start this am... When i crack the injector lines, i got fuel at injectors 3 and 4, but not at #1 (didn't check the rest yet). Can't figure out why if wouldn't have fuel at #1, but does at #3 and #4??? I've swapped the relays around for the shut off module, and check the wiring plugs to make sure they're tight, any other ideas?
