where is the injector fuse located?

Not sure where your fuse boxes are. But there can be a box under the glove box, another under the hood. Under the hood on the firewall are the larger fuses.

Sorry for rezzing an old post but Im having a similar problem. Just got the oil changed yesterday, drove 50 miles to school as i turned the corner on to my apartments road it bogged down then continued on fine, I stopped shut it off took my stuff inside (maybe 20 minutes) came out to go get some grub, wouldn't start...I cranked it over and gave it gas and got a plume of blueish/white smoke, now its cranking over and wanting to start but doesn't catch. Ive checked the oil it looked low so I added a quart now its over full i believe, clear good oil not muddy or murky.

Today Ive replaced the fuel filter, pulled my plugs, they appeared to be oil fouled pretty bad so I plan to replace those tomorrow.
Im getting spark from the front 3 cylinders as Ive tested them all I haven't messed with the back 3 yet. If i let it sit for a good while I almost catches and starts. Can I get some help please? lol Im stuck 50 miles from home and running out of ideas lol

do you hear the fuel pump prime when you turn the key?

Yup sure do

if you have spark, and you hear the pump i guess next would be check to see if you have the right pressure and its not bleeding off

what would I do if Im not getting the right pressure? Replace the fuel pressure sensor? If so where is that located?

if your pressure is low it could be the pump starting to go or he filter clogged or a fuel leak, if the pressure comes up but goes right away thats usually the fuel pressure regulator

Can you tell me where to locate that regulator?
