Truck won't start

We have a 2006 Tacoma we bought from someone. The previous owner blew a radiator hose off and ran it hot. We bought it, and replaced the head gaskets, vvt solenoids, both cam shaft position sensor, crank shaft position sensor. Would not fire so we put the old cam and crank sensors back in and still won't fire. Computer recognize the sensors but won't fire. No codes on computer. Checked all the grounds and still not cranking. Any ideas?

 

Is it getting fuel?

 

Yes we also replaced the fuel pump.

 

Is it not cranking, or not starting?

Need wayyyy more details for anyone to be able to help you out over the internet

 

Not starting.

 

Spark, fuel, timing.

Good chance at least one is off kilter

 

No spark

 

Swap the horn and fp relay, maybe. Check ign fuse

 

Already tried that.

 

Then you should get a misfire code. How did you even check for no spark?

 

Forgetting compression there, bud. OP said the (aluminum) engine overheated. Good chance it warped. OP didn’t say whether the heads (& block) were checked for straight or if they were machined (& if so, how much?).

OP, no disrespect, but it sounds like you didn’t do the head gasket job? So why not just ask whoever did what’s up??

 

Key on verify you have Power at the coils on Pin 1 (Black/Red) and Ground on Pin 4 (White/Black).

 

Power at coils have been verified.

 

We have it at a friend's house now who works on vehicles on the side. We checked for spark by pulling spark plug and grounding the coil pack and turn the engine over and no spark. Tried on one of the old spark plugs and still no spark. First time was a new spark plug. Also the friend check for spark also but I wasn't there when he did it so I don't know what he tried.

 

What about Ground?

 

And we did do the head gaskets job

 

Check all the grounds that I can remember. The ones on the back of the head and one on the fender by the battery. That's the only ones I know of.

 

Need to check if the coils have ground on the (White/Black) wire though.

 

Ok we will check that. Thanks
