Engine cranks but won't start

Have the fuel pressure checked to see if it is fuel related.

check for spark as the coil, pick up or module may have failed.

Good luck

Go to the inertia switch which is either on the rf kick panel on the passenger side or in the back trunk when you open the gate.
There should be power there for 2 seconds with the key on.

Then most likely you have a bad fuel pump.

Yep. I work at pepboys and we have the same issues with carter pumps. Try to stay away from them. Its more money to get a new ford pump but well worth it in the end.

Hi Will Whaley,

Thank you for the donation.

When engine refuses to start, there are basic items that you need to check, such as missing sparks or fuel. Click the following link and check out the symptoms listed. Go through the ones that matches your symptoms and find out what is missing. Let me know what you find and I will assist you from there.

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.

Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.

2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.

3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

4) If all of these things check good, then you would need to do a complete compression test.

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

Hi:
I feel the fuel pump is ok. If I had to guess, I would say plug wires, distributor. Have you replaced the ignition wires (If not, I would recommend that)? When the problem occurrs, does the vehicle fire at all or just crank? If you give it a shot of starting fluid will it run for a few seconds? Also, is the spark you see a strong snaping blue spark or is it more white or orange? Finally, at night time, I want you to mist the engine with water and try to start it. If there is a short, you will see it in the dark.

If the check engine light is on, lets start there. Take the vehicle to a nationally recognized parts store and have them scan the computer for codes. Chances are they will tell you it's a multiple missfire code, but they may come up with a different one.

Finally, does your Bronco have an ignition module on the side of the distributor?

Let me know,

Joe

Sounds like the fuel pump is no more good, running a pump out of gas is a good way to kill it.

And I would suspect it is bad since it hasnt restarted since its died out from no gas.

Your welcome, and hope you find your problem out.
