Okay.. Today I when out too start my truck and all its doing is just turns over. Heat coil come on, goes off as normal, get fuel to pump and all most wants too fires with in the 1st few cranks. But I will give you a bit of back ground with it. I have been have an issues with my heated drivers side seat. It seem too be a power issues because once get back up to normal range voltage range, I can turn off the truck, turn it on again the heat seat works. So Yesterday I was clean the posts and all the ends. So I am looking at the voltage when it 1st comes up and its under 9 volts? SO I have the charger on and I have the heater cored plug in.

I notice on the passager side there is a solenoid next too the air filter. It only stays on for a few sec? Tested with a test light.

 

Okay.. Found my problem.. I have a cut off value at my intake manifold, found out i bump the actuator and it shut the valve.

 

Glad you solved your problem! Post up pictures and details if you can just in-case someone else has the same problem in the future.

 

So at the top of switch, I notice I was clean and looking at this and my hand bumped that shock looking thing which was spring loaded too a cut off on the intake. In that picture of the spring what is what kills the intake. So I had too rewind the spring so it could set on that plunger. And then it fired up again..

 

So i noticed this is like its a run away kill switch? or something...
