Just got my 1992 Toyota pickup with the 22RE put back together the other day. Basically rebuilt the top end plus new timing chain and other new parts. Did not have the injectors rebuilt, but I did clean up the holes where the injector seats into the lower intake, and I did install seal kits for each injector.
Went to crank it for the first time, and it fired right up. Started smelling fuel after it ran for about a minute, but could not find a visible leak. Shut it off, and looked for seeping around the fuel connections, but could not find any leaks. Started the engine the second time, and the fuel smell got stronger, and it ran for about another minute before I shut it down. Engine did start to lope right before I shut it down because it was being flooded with fuel.
Fuel was 100% coming out of the exhaust. It was pumping so much fuel it was ridiculous. It has been sitting the last two days waiting on me to fix it. I was so mad at the time because I had put so much love, labor, and money into it. An old gent I know said just walk away from it, and let it sit for a couple days, and then fix it, so that's what I am trying to do now.
Stuck open injector/s, grounded injector/s, fuel pressure regulator stuck closed not allowing fuel to return to tank, and cold start injector malfunctioning by continuously pumping fuel when it's only suppose to pump fuel for seconds on startup is the only things I know that would cause the over fueling.
Going to install a new Kyosan pressure regulator and some new injectors. Want to do some testing before those parts come in. Can't find a noid light that will plug into a Denso fuel injector harness to check and see if I am getting pulses instead of staying on to rule out a grounded injector. None of the noid kits that I have looked at mention Toyota.
Need my truck, so any and all advice would be appreciated. Thanks!
