Gauge is fixed so now I can see again yay

I'll check IAC in the morning. Need to reinstall plugs and hit up O'Reilly for a couple of odds and ends. Lost my schrader valve cap, need bed bolts and throttle body cleaner (not specifically for this)

 

I think it should fire immediately with 40 psi

 

I am confused by what this is supposed to mean

 

He is saying you Engine should Identify as a running engine at 40 PSI. It should not be Confused on how it identifies and hesitate to start...

How ever, If I remember the spec was 48-52 PSI. Pulling the vacuum source to the FPR at idle I believe should have the PSI raise 8 PSI

 

Oh, sorry. I meant that it fit is sitting there with 40 PSI when you try to start it, it should fire immediately. It should not need to be cranked and cranked until you build the fuel pressure up

 

In my opinion

 

I have an aftermarket in line regulator. It does not close the diaphragm has does the stock GM regulator. So when I shut my engine off, the fuel pressure immediately drops to zero. When I start my engine, I have to turn the key to the run position for 3 seconds and then crank the engine. When I do this, it fires immediately. If I don't do this, it will crank and crank until the fuel pressure rises and then it will fire. If you turn your key on, to the run position, for 3 seconds and then crank it after that, does it start immediately?

 

My fuel pressure is in spec to fire the engine. I am at 55 key on engine off.
I still am getting a long crank and then turn key off the crank again and it fires right up. Nothing has changed on that front.




here is my MAP sensor. Looks pretty gunky but I’m not sure. I will get a log here shortly of the truck as it idles.

how to log MAF and MAP information? Which channel do I use? When I search MAF there are a couple of options.

 

Why do we keep talking about fuel pumps and pressure regulators, then?

 

Originally pump was out of spec fuel pressure. And it seemed like it was a crappy fueling problem

sorry for the confusion

​​​​​@1FastBrick That is how my FPR works right now. 8 psi increase.
