2002 2.7 Tacoma, Starts, and idles ok, but starves out when accelerated, will go to about 3grand on gradual before it starves. I have cleaned throttle body, & MAF. 89k miles, no evidence of shadetree tampering, all hoses,clamps are as they should be. Could it be the filter clogged, or weak fuel pump,or??? You can hear pump running when switched on.
Edited to say...what is the psi for the fuel pump, and where is the test port located?
