While your fuel pressure does seem low, your gauge may not be that accurate anyway. The MFI system is designed to increase the injector open time when there is "too much" oxygen in the exhaust, so...

I don't know. The EWD doesn't show the wire color from the connector to the lamp, just from the harness to the connector.

1.Yes.
2. You can't reuse the head gaskets, but you don't need to replace the bolts. (Toyota has a TSB that says you can reuse the head bolts. Or you can believe anyone else.)
3. You can grind...

So let's find out. Get some 6mm (1/4") clear vinyl tubing, disconnect the fuel return from the FPR, and run the vinyl to a suitable container. (This is low pressure, so there are no crush washers to...

I no authority on this, but if your existing head passed reasonable tests (pressure test, flatness, valve-seat condition), I'd keep it. Toyota heads don't really "wear out," something happened to...

Absolutely. I use my (lower torque range) 1/4" drive on my bicycles, too, but it is worth having it just for all the smaller bolts on the truck.

Welcome to YotaTech.

First, you're over-thinking the valve timing. The 3VZE is a "non-interference" engine, so you can turn the cams all you want without colliding with the piston. So turn the...

The same way you always do. And no, it's not with it hanging on an engine hoist or sitting on the ground. And I certainly wouldn't risk wailing on the the webs of the camshaft sprocket.

Your fuel pump doesn't "prime." It doesn't turn on until you turn the key to STArt (so you won't hear it over the starter).

If it's that bad, you should be able to see it on the pads (which you will need to remove to look at them). If one of the right pads is more worn than the other, then I'd go with snippits suggestion....

Well, you've confirmed fuel pressure (technically, you've only confirmed enough pressure to open the FPR, but the FPR isn't likely to be THAT temperature sensitive). Have you used the inductive lead...

.3 miles/gallon? .3°?

Do you have the FSM? I can't imagine trying to do an engine rebuild without it, but I suppose people try it. After all, you DON'T have a maf [mass air flow] sensor. Here's...

Welcome to YotaTech.


What do you mean "no fuel"? First, jumper FP to B+ (this forces the fuel pump to run with key-on, bypassing the VAF-COR circuit) (4crawler has pictures to help you find that...

But when it becomes too costly to keep an eye on a dwindling number of anything, it's much more cost-effective to simply ban that thing. It's no secret that one of the great triumphs of...

I find it hard to believe that a vacuum leak (as we usually think about it) would be enough to cause this problem. After all, at idle the engine is pulling enough flow through a nearly-closed...

Do you have any other "air" lines left open? Resonator, PAIR, EGR, A/C Idle-Up, ... As RJR says, it's not enough that air is getting into the intake manifold. It ALL has to go through the VAF.
