P1300 Code, Replaced Spark Plugs Now Won't Start

cruxofthebisquit · Apr 16, 2020

One thing to check first would be the spark plug boot that goes down the well. Most likely would throw a mis-fire only but strange things happen with voltage leaks.

I am currently throwing this code P1300 (#1) and P1310 (same igniter code, but #3) on my 3rz. I just rebuilt the motor and am trying to figure this all out. I do not have an igniter on my year of truck. I have two coil packs and have checked all these ground. I did not remove the harness from the computer behind the glove box and haven't removed it to look at it either. I am kind of stumped as to what could be my problem since I've once overed pretty much all of the connections running to this. I stored my coil packs in the bed with a topper that leaks a little and it rained a few times pretty hard....dont think they got wet though. I am pretty much at a loss as to what to check next. I am going to check spark tomorrow and keep looking at wires. Any suggestions? Someone said check if timing is still good? I have 150+ compression on all cylinders though.

On that engine the igniters are part of the coil pack.

You have igniter 1 and igniter 2 to trip that code most likely a poor connection .

Clean the coil pack plugs with electric clean as well as the harness side as well.

i know this has been 3 years ago and would love to know what you figured out, currently dealing with sort of the same problem. So i bought an engine with about 65k miles with coil on plug for each one (couldn’t find a motor with side mounted coil packs) but got all that converted over with no problem. Throwing a P1300 and P1310 motor will not start. Coil packs are good. Crank and cam sensor seem to be okay. Now im lost with it.
