dony know, having the same problem- replaced reg. / probably fuel pump diaphragm
55 PSI to 62 PSI no higher are lower are you will have starting or running problems.
9 to 13 LBS. No higher are lower are you will have starting and running problems.
9 to 13 LBS. It must not be 1 # lower are higher. If it is then you will have starting and running problems.
yes
Locate the fuel pressure regulator on the driver side of the intake plenum. Remove the vacuum line from the regulator and see if fuel comes out of the vacuum line. This is a very common problem with the 4.8 and 5.3 engines. And this problem will also not set a diagnostic trouble code.
Check fuel pressure, fuel pressure regulator.
the fuel pressure regulator on the fuel rail might be bad
55 to 62 PSI ( KEY ON ENGINE OFF ) If it is lower then 55 and higher then 62 then you will have starting are running problems. Must be on the money.
You need to run fuel pressure test on fuel pump with a gauge. It should have 9 to 13 LBS. no less and no higher are you will have running are starting problems.
You could have a faulty fuel pressure regulator or defective ignition switch. You could have a faulty fuel pressure regulator or defective ignition switch. You're not real clear on the starting problem as to whether it won't crank or just takes several tries before it starts. Maybe you just need a tune-up.
No. Check the battery first. Then test for spark, fuel pressure, and test your coils.
Hard starting is typically a sign of a bad fuel pressure regulator. If the car starts and runs fine after a few cycles of the key, that would be a good indicator of this problem. The regulator should hold pressure in the system, when they fail, the pressure drops and the fuel pump has to cycle when the car is cranked to build pressure back up. Replacing this part is a good place to start.
