Fuel pump?

Nvm, not just a second gen thing... gadget at urd in an old post verifies on 1st gen, they relied on rpm signal to prime
 
granted the 2tr, but I highly doubt toyota would reinvent this procedure just for the 4cyl............ Ill keep searching fsm tho

and here you go sir.... 1grfe
engine must be cranked.

the sound u hear at "on" but not running is not the fuel pump...........cannot be, no power is sent to it yet

Ill agree to disagree. Pump wont prime until crank.
Ill take the techs word until i see different on paper, plus
Replacing fuel filter few months ago, truck took a few seconds upon initial startup.
Also if it primed without crank, then the good ole urd kit ovetightening hose clamp leading to leak fiasco wouldnt happen at startup as the system should prime before cranking as u say.
Maybe its a 2nd gen thing

im not even quite sure if the OPs problem is a fuel one, it seems more like a misfire or MAF/sensor issue but he says that there wasn't any check engine trouble codes sent,usually when a vehicle behaves like his a code will be throwno_O but anyway he cleaned the MAF and seems to be running OK now.

Just wanted to share some info that may come in handy at a later date. 1 cannot rely on the good ole noise to ensure fuel pump runs. Facts were posted in effort to clear things up is all.
Just didnt want someone to read partially thru the thread if they had similar problems and assume the fuel pump was running when it wasnt. We all skip lines sometimes, ive done it a ton.

Always chebby TEST a fuse... you cannot simply look at a fuse and tell if its bad all the time. They dont always show an obvious break or char.
Again, turtlepower seems to be reference quite fitting johnny as per dx and jibberalison rectifying.
