hard starting
Greetings. New to forum with a 2001 4Runner SR5/auto. This is the "Boss's" vehicle in every way....she researched it, compared it and picked it out, and it has given us nearly trouble-free service. Now, with 104K mi, it has decided it wants to balk on start up....will try to catch and then die. After that, it takes 2 or more cycles of cranking to the edge before it will fire: as in "don't crank it longer than X seconds to avoid overheating the starter". Once it starts, it runs fine. Service and maintainance are kept up with at a near **** pace, including the timing belt.
I'm an old street rodder (my first car, and first love: a '65 Mustang 2+2 *a "fastback" for you non-'stang guys*) so I know the basics of "fuel, air, fire", but without the diagnostic equipment, I'm lost on the electronic complications on this one.
Anyone else run into this? ECU? O2 sensor? Coil packs? I'm thinking it's not going to be the fuel pump or filter, because it runs fine once it starts.
Any thoughts will be appreciated. Thanks

RE: hard starting
Thanks for the response. Had the codes read, no code showing. No, no problems with turning the engine....normal cranking speed. I'm leaning toward a fuel delivery problem, but so far, no repeat of symptons. Will post anything new as it occurs.

Hey, what ever happened with your truck? I have a 2000 4Runner that's having the same problem. When the engine is warm it's hard to start. Will crank fine just won't fire. I've had it to my mechanic twice to read error codes and there aren't any. I'm suspecting an electrical problem in the ignition switch. Could use some help.
