problems with my bronco?

Question

I was parked at a red light yesterday and my bronco just shut off, no shuddering or anything, no problems before, it just plain shut off like someone flipped a switch. I checked the colission fuel shutoff switch but it was fine, I replaced the ECM, I can hear the fuel pump prime when i turn the ignition but its like its not getting any fuel or spark. Any suggestions???

Answer 1

it might be the fuel pump relay.

Answer 2

I'm dealing with a similar problem on my aerostar right now
I've replaced my intake air temp sensor
and my ignition control module with no result.
You can do a self diagnostic test if you can find the test connectors, mine were under the hood on the drivers side.
Look for a black box that says "EEC TEST" they are plugged into that, unplug them and follow the directions on this link.
If you can't find them under the hood check under the drivers dash.

turn the key to the on posistion but DON'T start it with the paper clip still in! REMEMBER THAT! as soon as you are sure you know the code remove the clip and put the connectors back.
After you turn the key it will flash (dim maybe once)
and pause between numbers for example if the code # is 124 you will see flash, pause, flash flash, pause, flash flash flash flash, done, there are 2 and 3 number codes and there may be more than 1 problem code so watch closely, write it down, and do it a couple times (just turn the ignition off, wait a few seconds and turn it back on and it will restart telling you the problem codes

A couple other things you could try
Spray starting fluid directly into the throttle body while you hold it open; if it starts after you do that, you have a fuel problem. Just because the pump runs doesn't mean its building enough pressure. If thats a no go, then check for spark by holding the coil wire about a quarter inch from a good ground (using insulated pliers); the spark should by clear and blue, not orange. If it's orange and dull, you may have a bad coil wire or coil. If no spark, you may have a bad pick-up coil in the distributor or a bad ignition coil. These things require knowledge and tools I have to assume you have. If spark is good, make the same test at the end of a plug wire... no spark, bad cap/rotor. This should keep you busy for a while, good luck.

Answer 3

I'd have the ignition module checked. It's mounted on the distribitor. You can take it off and take it to somewhere like autozone to be tested
