5.0 Engine Pings and Clicks after trying to Start Cold Motor
#12
Requiring starter fluid to get it going would indicate a fuel or air problem. You clearly have enough fuel pressure now. After trying to start it and it just cranks, pull one of the spark plugs to see it and/or the piston head is wet. If they are then you know that your getting fuel into the cylinders.
Also, when you add starter fluid, where are you adding it? By turning the throttle plate in the throttle body and squirting the fluid in? If so, try cranking it normally and turn the throttle plate by hand like you were going to add starter fluid, but don’t add starter fluid. See if it starts that way. If so, then the problem is that not enough air is getting into the cylinders.
Good luck...

I inspected the salt and pepper shakers they have no corrosion and are pack with dielectric grease. In by previous post I did not mention the red wire on the injector harness have 12v to it when key is on. Idle Speed Control has been cleaned.
Thanks
Thanks

I wouldn’t do that jumper thing any more. If the injector was power side switched (where it has constant ground and the computer turns the power on/off really fast to make the injector pulse) you would have flooded that cylinder with gas and possibly hydro-locked the motor when you tried to start it because the injector would have been wide open and gushing fuel. I think you got lucky and the injectors are ground side switched (where it has constant power and the ground is turn off/on really fast by the computer to pulse the injector.)
Without a circuit diagram its hard to say, but it sounds like the injectors are all ground side switched and they all share a common power source. So by giving power to that specific wire in injector #5 you gave power to all of the injectors. Yeah, you got lucky… If you picked the wrong wire you would be in for a world of hurt (hydro-lock).
Anyway, it sounds like the injectors are not getting power during startup but are once the motor is running. Yeah that is strange. I don’t know the injector circuit for your year/model ride, so I can’t really give you any pointers on where to go next. If you have the circuit diagram for the ignition circuit (or get it from alldatadiy.com) and post it up I might be able to tell you where to look. There may be some sensor or relay that isn’t working properly.
