Heres is my fuel pressure, what does this mean?

I would guess that your problem is not from the fuel pressure. Perhaps it is from a dirty throttle body.

 

already cleaned, cleaned iacv, maybe tps? At this point id be throwing the part on just to change it, idk what else to do.

 

Maybe you should try and see what controls the cold start up, maybe a sensor.

 

Maybe the ect sensor?

 

the ect sensor? i never have it pushed on unless im on the highway or on hills.

 

What are you talking about when you say you don’t have it pushed on? When I say ect sensor I’m talking about engine coolant temp sensor. It will give issues on cold start if it is faulty.

 

The coolant temp sensor detect how hot or cold the coolant is. When you start your vehicle in the morning the temp sensor send a signal to your ecu telling it to add more fuel. If the sensor is faulty it can send the wrong signal to the ecu. You can check your temp sensor using a scan tool. When you monitor the sensor the temp should gradually increase as the truck get warmer.

 

ohhh sorry I never heard of that part. I’ll check it with live data tomorrow morning. Will that cause rough idle after it warms up? When I turn ac on my vehicle idles fine ar a red light.
