Timing chain replaced...truck won't start!!!

Ok...so my tundra had a #7 misfire, I saw oil was in the spark plug tube, so I pulled the valve covers and changes the seals. While doing this, I checked the timing chain because it had been making the some noise...(truck has 350,000 miles). I decided to change the timing chain, water pump, fuel injectors and thermostat. I try to start it and it doesn't start, just turns over. I know I am getting fuel because I pulled a plug and there was fuel in there. With all that said. What should my next steps be to trouble shoot?

 

Set timing right

 

Pretty sure timing is good to go.

 

Crank and cam sensors plugged in?

 

Make sure your wires and hoses are all where they need to be. Right order.
Try turning the key to the acc/on and letting it sit for a minute then turn ignition on.

 

Sensors are plugged in...I did clean the sensors when I had them out with carb cleaner. Would that damage them?

 

Maybe it. Carb cleaner is harsh and leaves a residue

 

Crankshaft position sensor?

Did you pull the engine? or did it in the truck??

 

Does it have spark?

 

Is there only one instance where all the timing marks and plates line up?

 

You can pull a coil pack and plug out, stuff the plug back in the coil pack, then let the body of the plug rest against the metal valve cover. Have someone crank your truck, then you can look for spark.

No spark when starting is generally a sensor problem. Use a scan tool with live data to look for what's missing. You can also unplug each one then plug them back in and listen for the click of the plastic plug.

Carb cleaner is a little rough on those, but i would expect that you would see cracked plastic if there was an issue.

 

It sparks once every second. Does not have normal spark.

 

Impressive work on the timing change replacement btw. How long did that take you?

 

The truck won't start...Hardly impressive...3 days and still trying to figure it out.

 

Yes, when #1 is at TDC the camshaft chain timing link and crank pulley mark should align with the block / cylinder head marks, it will take several rotations to get them to align again. Does it sound like it's sputtering, or just cranking with no attempt at starting? Double-check your plugs and vacuum / fuel lines, there's a lot to remove to do this job and easy to overlook something during reassembly. Sounds like you verified fuel, to test spark, try pulling a plug, connect it to the plugged-in coil boot and see if it sparks against the valve cover. Do you have a compression test kit, or can you rent one? If the timing is off, your cylinder compression probably won't hold.

 

ok...so that rules out that I got the timing wrong. Is there a way that I can verify that the cam position sensors are working?

 

And it is just cranking. It sputtered a time or two.

 

I'm sure there is a process, but I'm not familiar with it. Any chance the fuel lines got mixed up, like the pressure line got swapped with the return line?

 

I don't believe so. I did replace all the fuel injectors. There was a lot of debris that fell into the ports when I removed the fuel rail. I don't think that this would cause it not to fire though. I will probably pull the rails again, check the fuel lines for pressure.

 

I would start with simple stuff first.
Double check the electrical connections.
If you didn’t disconnect the battery before you started I would look through the fuse box. Just to make sure you didn’t accidentally short something.

I know that you said one of the plugs was wet with fuel but I would still try some starting fluid. If it starts on ether I would think it is a fuel issue. If it does not start on ether it is something else.

 

I appreciate the feed back and will keep this thread posted as I start to eliminate possibilities and or if I find the issue.

 

I tried starting the truck last night but it just cranked with no start. The truck sat overnight. I went out and tried cranking it. It started rough for about 20 seconds and then died. When I tried starting it again. It was just cranking. Thoughts?

 

I there a possibility that there's air in the fuel injector lines. I know you sometimes have to purge the fuel lines on some FI systems when you replace the injectors.

 

Hmmm....Looks Like I will be doing that next. Thanks

 

Ok so...

1. We have fuel going to the rail.
2. There is spark.
3. Compression is Cylinder :
1. 180 psi. 2. 140 psi
3. 180psi 4. 170 psi
5. 150 psi. 6. 160 psi
7. 180 psi. 8. 80 psi
Truck tried to start real rough...suggestions.

 

its actually pretty common for the VVTI solenoid wires to be flipped and plugged in wrong on this engine.
this will cause a no start or hard start

 

I will check them.

 

Would the cylinders have compression if it was out of time.

 

Not really. Because out of time means meant valves
