Okay, I did a search, and learned alot of new things, but not what I came here to learn.
On Friday, I drove the MJ to the store. When I came out and tried to start it, it nearly caught on about the 3rd rotation, but didn't. After which it took a good while of cranking (multiple attempts) before it started. Once it did, it ran...okay, it ran about as good as it usually did (don't get me started).
Then on Saturday, it did it again while I went to another store. Again took a while to start. This occurred twice again at a couple of stops I made. In between those, one time it cranked right up when I got in and turned the key.
After it not starting, then finally catching, it would rev like mad for a sec, I assumed as it burned up the gas that was in the TBI/manifold/cylinders?
I had a bottle of fuel injector cleaner I'd been meaning to put in this week, and decided to drop that in Sunday morning. I tried to start it and let it run for a bit, but it again nearly caught and then just cranked without starting. It's been that way ever since.
If I dump a couple tablespoons of fuel into the carb, it runs for the second or so until that fuel is gone.
So, we come to what I think is the logical conclusion that it's not getting fuel. Altho that doesn't explain why it revved outta control when it DID start.
But my question is, is there a way to find out whether it's the pump, filter, injector, or something else I haven't thought of without just throwing parts at it?
The Haynes manual says to connect a pressure gauge (which I don't have) to the TBI and let it run for 30-40 seconds.
:huh:
Kinda hard to do right now...
Any ideas, oh great masters of the best Jeeps of all? :viking:
