1992 Bronco Dies
1992 Bronco, 351. I am having issues with it cutting out and stalling. Fuel pressure is solid, replaced fuel filter. Any other ideas? Facility inertia switch?

Check the throttle position sensor and idle air control to start.

Re: 1992 Bronco Dies
To eliminate fuel pressure from the pump as a concern, press the schraeder valve on the fuel rail down and see if it has good psi coming out of it, or fuel at all.
After that, I would do what Brandon above me suggested. Always remember you only need 3 main components for an engine to fire, oxygen, which obviously is around or we’d have bigger problems lol, fuel, and spark. So if you confirm that you have good fuel pressure then I’d say you could eliminate fuel as a concern all together as it would just run poorly if it was an injector or something.

Nevermind on the fuel, I need to learn to read completely rather than just scanning posts.

New fuel filter, Still does it.
New ICM, Still does it.
Replacing IACV tomorrow. Fingers crossed.

It does have a MAF swap done with Mustang ICM, Distributor and ECU.

Re: 1992 Bronco Dies
We found the issue. The fuel pump relay was faulty. Replaced with new Ford unit.
