    Please , can anyone shed some light here. I've done timing belt w/ pump replacement, all went smooth, belt lines up on "I" marks, turned by hand a few times. Problem is, it cranks, but will NOT start at all, since I have no spark, none. Tested Crank sensor, it's good, where to from here? I have also checked every single fuse, in Engine Bay & inside cabin, drivers side??? I am in trouble here, need this truck to run. Thank you in advance guys....

    Welcome from Ontario Canada, I would retrace your steps and see if you inadvertently knocked a wire off or something . Was it running before you did the timing belt and water pump ?

    I joined to see what is possible
    and do you smell gas filling up in your piston? or coming out your exhaust when cranking?

    Well, it was running 100% before we changed the belt, no issues at all. We pulled the plug on No1 piston, grounded it (connected to it's coil) and cranked it over, no spark at all.I can also hear the fuel pump running. The odd thing is that the "check engine" light does not come on at all when I switch it on. We connected a code reader to the truck, it could not connect to the ECU.

    Well, here's my feedback on this thread. The problem got solved, in no time. We nicked the wiring going to the Cam Sensor. Even though we checked when re-assembling, there was a spot we didn’t see, so, fixed it, perfect, no issues, Tundra is purring like a lion! Thanks everyone for contributing, this is a great Forum!

    Absolutely! What threw me off balance with this one was the 4L & 4H buzzer going off,warning light coming on, but no engine light coming on. Due to my lack of experience I figured it must be something pretty serious, 'cause everything seemed to be messed up. Just love this forum.!
