I recently bought an 87 pickup with the 22RTE motor and despite some rust in the bed ran great. That is until the other day when it just started idling weird and had no power, so I pulled off into a parking lot when it just died. After that I couldn't get it to start again. The oil has been changed recently, battery is charged, the engine will crank over just fine. I can't seem to figure out what is actually wrong with it. Going through my Chiltons I have tried replacing the O2 sensor, the spark plugs and wires, and the ignition coil. It will now start but die unless I give it plenty of gas all the while the engine is acting like it is misfiring and a cloud of gas is pouring out of my exhaust. I need help big time, please anyone.

PS: I have checked for any leaks in vaccum lines and I can't find any...

rowdy235

have you checked the timing?

rdharper

Check the VAFM, and the TPS.

does the turbo still spin? If the turbo seazed and is not letting any air by the engine will not run. correct me guys in i am wrong on that.

Check ALL of your fuses and the EGR valve operation.

If the turbo is siezed, the engine will still run since air can still get past the impeller and turbine blades.

Alex 400

would it run very well? I mean i thought a turbo had tighter tollerances than that so that it could actually compress the air to make boost, or at least on the exhaust side more so.

It should still run 'okay', but you won't get the extra horsepower from the turbo.

You really can't do that other than visual inspection without having the truck run.


Start with the basics - forget the 22RTE specific stuff.
Do you have spark?
Are you triggering your injectors (test light)?
Any thrown codes / check engine light

I haven't checked the timing yet, I will probably check that and the turbo next. I did manage to get it to start but alot of gas vapor comes out of the exhaust and it dies easily. I'm also getting excessive engine vibration now, almost like one of the cylinders isn't firing properly. Note, the check engine light did come on the day previous to it dying but I thought it to possibly be my O2 sensor since my mileage wasn't the best and I had experienced something similar in another toyo that I had owned. As for error coded I don't know how to check those for a toyota.

just a 22re

search for a how to on the engine light as i dont know how my self. and as for poor power and what not. id check the afm and TPS timing i dont think would have jumped that far unless the chain jumped. but then again it might have

kipres

mass air flow sensor is clogged or is bad check that.

dcg9381

Gas out the exhaust could indicate a messed up engine temp sensor (on front of the lower manifold) - you check it at the ecu.

I'd also TEST and calibrate my TPS.. Search for "4crawler TPS" on google.

AFM could do it..

Had one other thought... (on my 22rec).

Wife called from town one day. Engine had died. When I got there, I started it, but it felt like it was running on 3 cylinders.

Drove it home... hoping I wasn't doing further damage.

Pulled the valve cover (not much of a mechanic here, but its easy on the 2.7L engine)

Voila. broken exhaust valve spring on #2.

Dealer wanted $1000. Researched the subject here on Yotatech, as to how to replace the spring withought pulling the timing chain etc.

Took my FSM and the suggested technique to a local (trusted) Shell station. At first they didn't want to try it... then they called back and said they'd give it a try. Parts and labor.. less than $300.

That was over 5k and 2 years ago. Continues to run perfectly.

So if you can't run a compression check... you can pull the valve cover... and look... if it sounds like one piston is not working.

So it turns out the problem is the #1 injector failed open on its cycle and continuously discharged fuel into the cylinder causing it to hydro-lock and blow the head gasket. So I re placed the injectors the gasket, and machined the block and header. Its running now but I need to mess with the timing because the throttle response is lagging big time and gas mileage is bad.

rdharper

Injector failed open? That is scary.... I've assumed injectors are normally closed by spring action.. and it takes positive energy to open it. If it is as you say, it would have to have mechanically stuck open... hard enough such that the spring can't overcome it. Yikes.

Wow what a mess...would of never thought of that...
