So I decided to buy a 86 Bronco with a shitty engine and swap it out with the 302 out of my 89 f150.
Come to find out the 86 bronco had a 94 302 installed.
The swap worked out just fine until I tried to start the sucker.
Won't start! So I start troubleshooting.
I have spark to the plugs, wired correctly.
All grounds are connected as best I know.
Then I checked the fuel system and figured out my fuel-pump was not priming and pressurizing the system.
Checked inertia switch, it's in position but not getting power.
So here's what I did. I put in a new wiring harness which didn't help so I bypassed the fuel-pump relay with a toggle switch.
Now I have spark and fuel pressure, but the damn thing still won't start.
Don't think it makes a difference but I will try to swap the brains out today and see what that does.
I'm starting to get frustrated and would appreciate anything anybody might think of.

Sounds like the ground that comes off the negative battery cable to the fender.

to the fender? mine goes from the negative terminal to the engine block.
then your body is also grounded to the block and the frame....least mine is.
ajduby....make sure your grounds are clean and tight.is it even trying to start?

Not at all which tells me my injectors aren't firing.
I wonder if the injectors and the fuelpump are controlled by some common
factor, which would pinpoint the problem.
