Crazy stuff

I'm not sure that pumping the footfeed (thanks, Dad, for that word) does any good when starting a fuel injected engine. It's not like the accelerator pump on a carburetor.

I think cycling the ignition twice helps build more pressure (like if it's a low pressure issue.) Basically priming the fuel system twice could increase the pressure a few notches higher such that the injectors can actually fire.

...I guess I'm confused... Isn't a 2000 GMC Yukon Denali a carryover of the GMT400 line? There's a huge difference between those and the later generation on the fuel injection and ignition systems.

Considerable overlapping between GMT400 & GMT800 1500 pickup trucks in '99 & '00,
and GMT400 & GMT800 1500 suvs in '00.

Good question, but unless one knows that particular year's build style, it's just a guess. The OP didn't say which engine was in it, not that I saw in the posts.

should still be the GMT400 in that...I had a 2000 Escalade...it also was still GMT400 based
