hello
i recently used an fuel system/injector cleaner in my 2003 T&C 3.8L..used the stuff changedfuel filter and used a follow up product as per the conklin products instructions..well shortly after the van has been intermitently been stumbling and stalling (in traffic)..so it may be coincidence or the product may have cused clogging of the fuel filter..i waqnt to check the fuel pressure but cant find the schader valve on the fuel rail..how do i do a fuel pressure test?..is there a on board self diagnostics i can perform without a scan tool like the old caravans i.e.turning the key on and off three times?

 

i was not able to check the fuel pressure but did change the fuel filter again..4000 miles on old one..it seems to have taken care of the problem

 

They did away with screw on valves. You'll need to tap in with an adaptor...usually found in a tester kit. no there is no scan tool reading for fuel pressure
