I cannot start my Bronco. I do know that I have spark at the plugs. I am almost sure that it is not receiving fuel. The motor spins great but does not even try to start. I cannot be sure where the "fuel pump reset switch" is located. How about the fuel pump? Is this located on the top side of the tank?

Thanks for your help in advance!

 

Not uncommon for the pump relay under the hood to have a bad plug, especially if the truck has been used at all. Try checking it first. Also, on the 90 the crash switch is inisde the rear left? side panel as I recall

 

Where is the pump relay? Can you tell me what it looks like?

 

Jag,
Check for spark. Pull a plug wire, and observe spark in the usual manner, or connect a VOM meter. Fuel? Is there fuel in the tank? Try a shot of starter fluid into your air intake.

Fuel pump reset switch? Is there such a thing? The inertia switch, mentioned above, will only set after a pretty good impact. It can be reset with a screw driver blade.

Check fuel pump by disconnecting at the filter, then turning on ignition. Be careful.

good luck,

I've seen an inertia switch tripped by a good kick to the side of a Ranger before, but usually it takes a lot to trip them. That was a pretty difficult no-start diagnostic to perform. I was glad I wasn't the guy who kicked it and had to figure it out

 

inertia switches on rangers are easily tripped are't they on the pass side floor panel?
pump relay is in the engine compartment pass side black box

 

I had a inertia switch go bad once nd it drove me nuts for about 3 days til I figgured it out. but it never tripped, just failed and cut the fuel. ther dealer wanted big $$$$ for a replacement but the boneyard just up and let me scavenge one for free..

 

Is there one on '89 bronco's?

 

yup

 

should be front pass floorboard

 

What does this look like? I'm wondering cause I had a prob a while back that my fuel pump would cut off at high alitudes. I replaced the relay, but now after finding this out, mayby thats could be it too.

I need to know everthing about it, so that in case it happsends again, I know what to do.

 

it is a little box 2-3 inches long with a couple wires coming out the bottom and a button on top (usualy red)
it should be pass side floorboard left hand side

 

Sweet, thanks, I will look for it today.

 

get a chiltons. they tell you right where to look, like on my 96 it said look behind the pass kick panel and voila there it is. (look under the fuel filter replacement instructions)

 

Right in front of your brake pedel
