Engine/Transmission (1998.5 - 2002) Hard starts with FASS lift pump

[Jbelleque]

After installing a FASS lift pump the truck started hard when hot. Dodge replaced the injection pump under warranty and all was good for a short time. Three months later its doing the same thing, and Dodge wont replace the injection pump beacuse I'm now out of warranty. As per the FASS manual I installed a Hobb switch in the oil pressure, as to only have the lift pump work when there is oil pressure. Now it starts great, but I now have a check engine light (from cutting the ground wire from the ECM to the lift pump??). I have a otc scanner, but it wont read the code. The fuel pressure is a steady 16 psi. So my questions are; can I just ground the OEM ground wire to the lift pump, or will that cause a problem to the ECM, If the injection pump wont start with good fuel pressure is my fix only a band-aid to a faulty injection pump??



Thanks to all

Do you have a new or old fass? If it has a realy, go here http://turbodieselregister.com/forums/showthread.php?t=157858

A better alternative. If not, there is suoopsed to be a new reflash for the ecm that fixes the hard start problem. It's not a bad vp44, it has to do with too much pressure before the motor is running. Diesel_Dan in that thread is the guy to talk to, he's dealing with the fass now.
