Sorry - don't mean to confuse.

When you turn the key in the ignition, the engine "turns over" = meaning that the starter is working and the engine is spinning, but there is no spark/fuel firing. No "coughing" or "sputtering," then quitting. The key ignition in the truck is 100% and the starter is working and the engine is spinning from the starter, but there are no signs of air-fuel-spark happening inside the motor.

With all new coil packs, plugs and wires, I'm 99.9% sure there's spark, but will pull a plug tonight or tomorrow to verify.

What I was really trying to get a better idea on, was how many start attempts would be considered normal after doing a top end job and having the fuel rail and injectors "dry" from draining them for the repairs. In other words, how many crank attempts are necessary for the fuel rail to fill, pressurize properly, and the injectors to start sending fuel into the engine. Also, if there were any tips for accomplishing this process other than simply trying to crank the engine.

 

mollusc - I did not press the inertia fuel cut-off switch. I'll try that when I get home. I did not see that step covered in any of the videos or instructions that I saw. Thanks for the tip.

 

I have done two Disco head gasket jobs. On one truck I didn't have to press it. On the other I did, even though it had never been subjected to any jolts or other inertia movements. And it's a fuel cut-off switch, so it fits your situation.

 

Should start after just a few cranks

 

When I did mine after priming it fired up after about 2 - 3 turns.

But you need to start simple and not drive yourself crazy

1. Check for spark 1st that is an always the 1st thing - do not assume you have spark make sure
2. If you have spark check for fuel
3. check for air - sounds dumb until you find the rag you forgot to remove somewhere. But make sure you have the throttle body cables right
4. And yes as noted check the fuel cut off pretty easy just to eliminate that

 

Couple revolutions and my 04 rebuild was running.

You need to verify items, not guess "they're working or should be working". Pull a plug, check for spark, do you hear the fuel pump running while cranking engine (listen through filler tube)? Get back with us with results and we can offer more help. Also, cranking or turning over = battery and starter are doing this. Running or starting = engine is doing this, without the aid of battery and starter, and is using spark and fuel to achieve this.

 

Did you remove the cps or just unplug it? If you removed it, could you have put it back with the spacers incorrectly in?


CPS turns on the injectors.

 

And it's not of unheard of for the coil pack plugs to be forgotten. Usually, once you've battled with the bracket and mounting them...you're so pleased...you move on to the intake.

 

This won't be much help, but both times I did my head gaskets it started relatively normally. Double check your work. I am sure you will find the cause.

 

This! That’s what I was thinking too.
