Like CO ZX2 said, that's a bump-start. My question is, when you do this, do you feel a "jerk" or a "bump" when you put the car back in gear? Also, what is your MPH when you do this? I am curious because I like to know if it feels "rough" or "smooth" in terms of re-engaging the clutch on every person's car.

when I bump start it tends to be smooth, smooth enough that i have to check my tac to make sure that my engine started, it helps if you open the throttle just a little to give it less resitance when starting.

Thats what I was trying to describe. In my Ranger its more rough (I have to use the key). I put the Ranger in 5th and bump it in 5th quickly then change to the gear I need after start (re-starting in 5th seems to be least resistant). The crx is very smooth with the injector switch, I wouldn't even consider it a bump, I bump it in whatever gear I'm driving at highway speeds, and usually bump in second right before I stop at a stop sign so I don't have to use the key. Very nice indeed CO.

I usually select the gear I want to accelerate in ahead of time, set the throttle to about 2/3 and pop the clutch. Bump 'n go, minimal energy and clutch lost on slippage or time spent down shifting.

MPFI is going to bump start more smoothly than TBI for the same reasons they differ on killing fuel flow.

It's pretty bumpy in mine, probably about to get even rougher after I replace the clutch.

try this:

select the gear you want, then procede to bump-start as normal, but only let the clutch out ~90%, and then quickly reclutch.

it will be enough to get the engine spinning, but as the revs increase it won't be fighting the tranny.

I actually quit nice-off coasting for awhile because the bump start was so brutal in my car. but with this technique you dont feel a thing.

That's a very good description of what I do. One of us should you-tube it.
