Why can't I roll start

The only other 'new' stick vehicle I owned was my 02 Trans Am, god rest her soul. I can always push/roll start that. I can NOT roll start my S10. Why? At any speed at all, even a good 40mph, I'll clutch, shut off, turn the key to ON, and try and pop the clutch.....nothing. It'll actually roll in gear, without starting the engine. Why, is something screwed up with it?

Re: Why can't I roll start

I had a '96 Sonoma with the NPG-1500 and four-holer, and could only get that to roll-start maybe once out of ten attempts, second gear, ignition on, clutch drop. I never figured it out, but suspect it may be related to crank-cam timing and/or injector PW with the lack of a crank signal input from the ignition switch. I would just bump the starter for about half an engine rev and it would fire, so it was in great tune.

Frustrating, I know.

Re: Why can't I roll start

Roll or push starting can cause damage to the cat. GM warns against it. The lack of a Vats signal is probably what prevents it.

Re: Why can't I roll start

I used to do it in my '01, until I replaced my starter. Never had a problem.

Re: Why can't I roll start

Sucks, as this is my DD, and I'd like to be able to push start it should the need arise.

Re: Why can't I roll start

I have had this issue when I had a problem with my starter. I have the best luck doing roll starting if i can get over 10 mph.

Re: Why can't I roll start

Push starting the 2.2 S10 isn't easy. I attribute it to the gearing (too low), so reverse starts are just about impossible. I've managed it in 2nd, but it's a very brutal process ( kicking the clutch usually barks the tires).

Re: Why can't I roll start

I have tried with my 03 and it will attempt to fire but the security light comes on and it flashes.
As soon as I turn the key and start it normally, everything fires and runs normal.
I think the computer is looking for the key switch to actually get a start signal so it thinks a key is being used.
