Head Gasket Hell!
Hello everybody,
This is regarding a 1995 Toyota 4Runner SR5 4WD vehicle which I recently did a head gasket job on. It's a V6, 3.0 overhead cam engine.
After putting everything back together, the engine would crank smoothly and quickly, but the car would not start! I checked the distributor and spark plugs for spark; no problem there. The ignition system is working just fine apparently.
But after smelling the exhaust when attempting to start, AND after removing a couple spark plugs and looking for vaporized gasoline, I found NO evidence that the fuel injection is working at all.
So there's good compression, good spark, starter is fine, but NO ignition, apparently due to no fuel. What might have caused this problem? I had to disconnect all the FI ports from the ECU wire sheath, as well as remove the IM (of course), but I put all that stuff back the way it was when I was done.
What I would like to know from all you mechs here at the Auto forums, is what kind of EFI troubleshooting techniques are out there? I KNOW that I can remove the EFI and intake manifold without having to touch the timing belt or distributor, so Theoretically I could turn the key to ACC, crank the engine over by hand, and look to see if the fuel injectors are injecting fuel.
But would it work?
I am committed to solving this problem 100%. I recently got a copy of the Haynes Fuel Injection techbook, and I'm ready to take the whole thing apart again if necessary to find out what the heck is going on. If anyone has ANY advice to give whatsoever, I am all ears.
