What kind of fuel does a 24 valve pump use?
It’s an electronically controlled and regulated, distributor-style pump (also known as a rotary type) that was chosen to fuel the 24-valve due to its ability to meet the emissions standards of the late ‘90s. The VP44 is equipped with a computer (EDC) married to the top of it, which monitors and precisely adjusts in-cylinder fueling.
What happens when the lift pump on a VP44 fails?
Once the factory lift pump no longer provides adequate fuel supply pressure to the VP44 (and when it sees 0 psi for extended periods of time), the EDC atop the VP44 is exposed to extreme heat and eventually fails.
How much RWHp does a 24 valve P pump have?
For a street-driven P-pumped 24-valve application (such as the one shown here), even a mildly modified P7100 can net 650-to-700-rwhp with the right turbo.
Can a 24 valve pump be swapped for a 12 valve pump?
A reworked throttle linkage is warranted in a P-pump swap as well. This version incorporates the throttle position linkage ball from the 24-valve application into a linkage assembly originally designed for the 12-valve engine. It too is included in the Scheid Diesel P7100 conversion kit.
What causes a Dodge 24 valve to not start?
NO START: 1. Low or no supply pressure. Buy 24 Valve Fuel Supply Systems 2. No fuel – sending unit in tank defective. 3. If the supply pump recently failed, it could damage the injection pump and cause a no start. 4. Check for DTC, follow Powertrain Diagnostic Procedures Manual. 5.
What’s the difference between a VE pump and a 24 valve?
The main difference in valvetrain of the 24-valve was the addition of a rocker bridge which allowed one rocker to actuate two valves at the same time. While the VP44 physically resembled the VE pump from about 10 years earlier, the VP44 featured all electronic controls for fueling.
