2.3L ('02-'11) Help...

[Alex77tj]

Good evening..

Need some help.
I have a 02 Ranger with 2.3l dohc.
It has some issues starting the car.
Cyl 1 and 4 don't fire at allá and when I unplug the MAF they start firing.

I know i need to do some troubleshooting first because I may have a short in the wiring.

Do any of You guys have the wiring diagram?

i would appreciate your help

You can go to your local library and get a library card. Then get online, most libraries have a online resources page, and they will have a car repair section with wiring diagrams and other repair procedures. Below is an example. They have 15 pages of wiring diagrams just for the engine on your 2002 2.3.
