Changed valve cover gaskets but now it wont start 1999 tacoma

Hey guys my dad just replaced the valve cover gaskets on my truck now it wont start it will crank and act like its going to start then it just dies. Hes a experienced mechanic so i dont think he did anything wrong. Yall have any ideas of what it could be?

 

make sure you plugged in all electrical... are your spark plugs in? how long have you been trying?

 

Also make sure all your vacuum lines are hooked up as well

 

yeah everythings plugged in and iv been at work all day but he has been trying since atleast 2pm.

 

I just went and double checked and everything looks like its hooked up and in the right place

 

Make sure maf, iac valve, and Tps are plugged in. Also check throttle body gasket. It has to be the correct orientation or it will make the truck act funny.

 

Alrighty to the code on my truck is P1300 i looked it up and said its a problem with the igniter circuit no.1. anyone know of a good way to test and make the wiring and coil are still good?
