V8 GAS SOHC Naturally Aspiratedĥ.4L 330Cu.

If the pump bearings are crappy, it may be drawing high amperage.

Ref: White 3281,oldeguy,oilyspill et all - These are all familiar posts for me and all have good information - my 2002 has done the same recently - FYI - In checking these things note there is a pressure relief valve on the back of fuel rail on my 4.6 L - it looks similar to a tire valve stem and can carefully be depressed to check for fuel pressure shortly after cranking - also on some year ? models there is an emergency crash switch located behind and above the RH passenger kick panel that sometimes trips if one gets bumped ! In checking my problem further I find my fuel pump circuit has 2.This part is compatible with 19 vehicle(s) Notesĥ.4L 330Cu. Both have power at pins 30 even with the key turned off - It is indicated elswhere that the wiring schematics are the same for the 1997/2003 models however the parts involved are physically located in different locations and are identified differently - On mine they are located in the fuse/relay box on the front LH fender - while *oilyspill*does give a great picture of the individual relay diagram - and guides one on how to jump directly to the pump - I need a schematic that shows the whole fuel pump wiring system for a 2002 so I can see what else might be in the system - For safety reasons I would suggest using an ohmeter to check the fuel pump for ohms /and or shorts before throwing any unfused voltage at it. To start off with *WHITE3281* did not initially indicate what year his 150 was ? I have a 2002 model that began cranking and not starting on occasion and most recently will not start - it has no fuel pressure, relays K4 (fuel pump) and K163 PCM bench check O.K.
