Won't start replaced feulpump and feulpressure regulator and still won't what could it be

Have to remove inner door panel to see the issue &
possibly replace a broken window regulator

It could be the problem. The old wire may have been delivering less voltage than the new wire. Now that the wiring is good, too much voltage is going to the feulpump regulator. You need to have the fuel pressure checked.

Could be loosing fuel pressure thru the pressure regulator or the valve in the fuel pump. The pressure should hold for several days when the engine is off.
I would have the fuel pressure tested before and after you try to start the engine.

check fuel pressure regulator,throttle position sensor,mass air flow meter

That is like asking why your grass grows faster one week than the next

You use the window switch a lot --- so start there

Next, is the window regulator or cable broken -when
that happens the window usually falls down

The window motor may have fail in some way

I know you should check for a blown fuse but the other
windows work & if it did blow replacing it won't do a thing

If you have & know how to use a volt meter on any setting,
start by getting access to the switches

I doubt the locks are even on the same circuit

Personally I wouldn't even approach the vehicle
without a wiring diagram
Like going on a road trip,no map,why leave home
won't find anything or get to any place

Most people ask a question & go to a repair shop
or try thing the hard way because it costs nothing

Also gives no results

BAd headgasket or you have a bad cylinder. You need to have a compression check done on your vehicle

Messing up the look of your car !!!

If you carefully remove the door panel
& replace the window switch,regulator
or window motor,whichever is bad, there
won't be anything messed up

If your not a car person with some skills
& a lot of patience , then you shouldn't
try it.

CHECK ALTERNATOR 175 AMP MEGA FUSE. AND CHECK ALTERNATOR 20 AMP INLINE FUSE.IF FUSES OKAY.REPLACE BATTERY CABLES AND CHECK ALTERNATOR BATTERY FEED WIRE AND VOLTAGE REGULATOR WIRES FOR DAMAGE.AND CHECK DRIVE TENSION.MAKE SURE DRIVE BELT NOT DAMAGE OR SLIPPING.

probably one or both or your batteries are low or shot, check both of them. Hope this helps-Jim If water in them is low, refill with distilled water, and then charge them. If it still doesn't start, you may need a replacement.

The pressure regulator is bad,it is allowing the fuel to pass threw to the cylinders,replace the regulator,and a new set of goos spark plugs.This is the fuel pressure regulator.
