Toyyota tundra hood cable not connected to verticle rod connected to latch under grill.Hood is popped up 1 inch. How and where do I reach cable.

You'll have to try going thru the grille or from under the bumper to access the hood latch.
You might want to look at another GM product to gauge were the latch is in your car.
Sometimes you can use a coat hanger as a hook to pull the latch from outside the grille or between the grille and hood. Or use a long screwdriver from under the bumper.

I had the same problem on a 1993 Buick Lesabre. I could not pop the hood using convention methods(handle on driver side). I have good news . . . in my case it isn't nearly as difficult as I had researched. It turns out all I had to do was take a flat screwdriver underneath the car to reach the latch from behind the radiator. First take the grill off. Once you get the grill off you will be able to see from the front where the latch is. It will be nearly centered from the front of the hood about 10 inches back and 1 inch below the top of the hood. If you look carefully you will see a hole in the middle of the hood latch device. In my case I could not pop the latch from this hole from the front(although I hear it may be possible). Once you find the latch from the front grill side, go up underneath the car and reach up from behind the radiator with your flathead screwdriver and try to feel for the latch with it. You may need to be VERY patient because you will not be able to see what you're doing. Don't drop your screwdriver.

After I popped the hood, I found that the latch had simply become dislocated and was an easy fix. The whole fix took about an hour. About 30 minutes to find the latch from underneath the car and about 30 minutes fix it.

first, try smacking the hood at one of the front corners while someone else pulls the release handle. or even after you've pulled on it. if that works, once open, adjust and lubricate the hood latch assembly. if it still won't open, and it's the cable and not the latch you'll have to replace it anyway, so instead of removing the grill, cut the cable behind the pull lever under the dash where you can reach it. then skin the outer cable insulation away from the actual steel cable exposing an inch or two of it. then holding the insulation and plastic housing with pliers, grab the steel cable itself with pliers and pull it to open the hood. then replace the cable. the further you can reach up under the panel the better your chances of getting past the broken part of the cable and avoid removing the grill. you might also be able to gain access from up under the car if you're lucky.

there is no bypass have someone pull up on hood while pulling release or u can remove side panels in front of doors and battery its a couple of hours labor involved but there is an ex corvette engineer who makes a special tool with tool it takes 1 min to open costs about $20 call 18003983883 to order

There is no other way to release the hood other than either trying to reach the latch release from under the car or removing the grille.
