hard starting, 35psi ststic fuel pressure, 55psi running |
 |
The initial fuel pressure could be low or okay depending on whether this is a Newer body style Silverado or the Classic body style. Also matters which engine (need RPO code) and if the truck has a Fuel Pump Control Module (FPCM). Are there any codes present? When does the problem occur? Cold start, hot start? |
|
|
6.0 engine, newer body style, no codes. starts the worst in the morning, starts tough the rest of the day |
|
|
I had a code of p0430, and the engine rpo code is LY6 |
|
|
The P0430 code is a converter code and may be more of a symptomatic code rather than the cause of the hard start. This may be a fairly complicated problem to diagnose. I would need to know a lot more about the vehicle history and detailed explanation of the issue to help. Do you have a scan tool capable of reading engine data? How familiar are you with repairing this kind of issue? |
|
|
I don’t have a scan tool for engine data but i have someone that does, ill try to scan on Monday, as far as the history goes i bought this pickup 2 years ago with 200000 plus miles, its been a good starting pickup until recently. |

i can repair what ever the problem this turns out to be |

I was talking to my brother in law who runs a repair shop, he said to replace the battery, so i put a battery charger on the battery, turned the key and the fuel pressure went to 55psi and the pickup started right up. So i replaced the batterys(I run a snow plow so i have a dual battery set up). that was today, let see how it starts tomorrow. The old battery’s tested good enough for something older. |
