Oldsmobile Questions? Ask a Mechanic for Answers ASAP
Hi there. Welcome to our site!
According to what you state on your post, the only thing that would prevent that engine from starting on its own would be a clogged fuel rail or injectors. So, my man, yank that rail out of there and take a good look at it - worst case I've seen had rust inside the tube due to bad gas; ended up replacing the rail and all injectors.
Hope yours is not that bad. Let me know what you find.
No, sir. You're not missing anything :-) That test confirms the problem not to be caused by a plugged or restricted rail. Next test would be to disable the ignition system, then pull the rail up a bit so it's still connected and so are the six injectors still attached to it. Have a helper turn the key to START while you watch the injector nozzles. Does any fuel come out?
Ahhh... I'm sorry I got caught in the details and didn't think about the basics. We need to pull one of the valve covers and check for excessive timing chain play. Turn the crank pulley by hand clockwise until you see one the rockers starting to move. Mark that spot on the pulley. Then watch that same rocker as you turn the crank counterclockwise. Stop turning and mark the crank pulley as soon as you see the rocker move. Now look at the two marks on the pulley. If they're more than 5 degrees apart, the chain needs to be replaced.
Let me know what you find.
My friend, if there is spark and injector pulse, and the Check Engine Light comes on when you first turn the ignition on and then goes off, then that ECM is working as it should. Do you know how to retrieve codes shorting terminals A and B on the ALDL connector? If so, can you do that just for @#$%s and giggles?
If neither the ECM nor the timing chain turn out to be the cause of the no-start, then we're back to injection. You mention the injectors were "squirting" fuel. So, knowing they're supposed to spray a fine mist, could that be it? Do the plugs get wet when you try to start the engine? Is there good gas in the tank?
OK. That would bring us back to either the injectors not spraying correctly or not being kept open long enough by the ECM or the system not getting enough fuel pressure.
What happened to you getting me those codes? or telling me whether or not the plugs were getting wet? or if there was or not good gas in the tank?
I'm usually online after lunch Atlantic Standard Time. Catch up with you then.
I'm glad you have that Olds started.
