Tacoma won't start no check engine

Generally, as long as the Ecu is receiving a crank and cam position signal, it will provide spark and attempt to run the engine. Though different engine management systems have different requirements.

If you're timing belt was off by even one tooth, would not that prevent the engine from sealing to provide enough compression for combustion? I'm thinking that as the compression tester is a check valve, it's only recording the cylinder pressure for a fraction of the time that it normally would.

 

Have you used a vacuum gauge to make sure there is manifold vacuum being generated at crank?

Just to rule out idle air flow, you can use the throttle adjustment to ohh so slightly crack the throttle while you're starting it.

 

I am sure the timing chain is way off because the marks on the crankshaft pulley do not indicate top dead center I must have a bad pulley. I determined top dead center by sticking a straw in the spark plug hole and rotating the engine by hand. When the straw was at its highest point(top dead center) the mark on the pulley was not lined up with the 0 on the timing mark. I am not sure how it made compression that way but it did. Hopefully the valves did not contact the Pistons.

 

Did you set cam timing with pulley or mark on crank gear?

 

i set timing on the pulley unfortunately. I ordered a new one it should be here next week.

 

There is no reason to do that. You should only be using the cam and crank gear, and chain markers, for timing.

 

I agree. I only did it that way because I had already installed my oil pan and front cover. I really thought the crank pulley would give me top dead center. The pulley was brand new and it fit perfectly. My guess is that it was a defective pulley.

 

If this was a German engine, you would have destroyed the valves already. Yours will be fine, its non-interference.

 

That's what I am hoping for.

 

I'm a little confused. The crank pulley has a groove to fit over the key on the crankshaft. Is the timing mark on the new pulley not oriented correctly? I know some pulleys have rubber between the outer and inner part to damp vibrations and the pulley can possibly spin out of orientation when the rubber gets old, but I've never seen this personally, so I might not know what I'm talking about.

 

I ordered a new one and the grooves are not in the proper location and yes it's keyed onto the crankshaft. My old one separated at the rubber part and cut into my oil pump housing that's why I ordered a new one. I had never seen that before either.

 

At TDC the key is at the top?

 

I am not sure where the key is because I haven't removed the pulley yet. I will check it when I get the new one.

 

This thread needs less que que, more pew pew.

 

not sure but according to manual it uses the plated link method. Odd colored link lines up with marks.

 

They actually have a special service tool number for a ball pin hammer. Awesome.

 

SST = Stainless Steel Tapper

 

Oooooooh, I need to source one of these! Lol

 

So I replaced my crankshaft pulley and put the timing chain and distributor in the correct timing. Truck fired right up. Thanks for all of the help I really appreciate it this forum is awesome.

 

Good to hear man, good to hear.
