2008 fird escape tried to bypass the fuel relay now I have no power to the ignition or anything I was trying to drain the tank by making the pump run Mechanic's Assistant: Is the power loss consistent, or does it fluctuate? Consisttent weird it ran before but my daughter put diesel in it so I was draining it I jumped the relay now it is completely dead except the dome light Mechanic's Assistant: Are you fixing your Escape yourself? What have you tried so far? Thats it jumped the relay and now no power is there an ignition fuse or ecm fuse Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? No just jumped the relay and now no power so I am wondering what fuse etc I might have popped because it makes no sense

Hello and welcome to Just Answer. My name is \*\*\*\*\* \*\*\*\*\* I will the expert to assist you this evening. I'm sorry to hear you're having issues with your Ford. I know how frustrating it can be. Because I am not there nor am I aware of your level of automotive expertise I may need to ask questions in order to provide the best possible service. You mention you jumped the Fuel Pump relay and now you have nothing except the Dome Light. Do any accessories work at all? Radio? Windows ?(if power) [Brake](/topics-brake-ford/) Lights or Tail Lights?

HelloNothing no windows but lights workLights work but I have no dash indicators.
Automotive Expert
OK, I'm getting the diagram for you. Be right back.

The only thing on is the anti theft blinksOkOnly one of my diodes has power

Automotive Expert
OK, you already have the layout. Which Diode has power?

I checked A and B they are good
Automotive Expert
Based on what you've told me it sounds like the relay may have been jumped backwards resulting in a dead short to ground. It is possible you have a damaged ECU. Do you have access to a DVOM? (Digital Volt Ohm Meter) and a Scan Tool?

I just pit the one diod that has continuity in the PCM slotNoDihital ohm metrer yes my scanner doesnt work for this car
Automotive Expert
OK, without knowing what Control Units are on and talking to each other and not knowing what codes are in which modules makes it very hard to diagnose. I can only suggest you start by checking all fuses to ensure they're good. Start with the Fusible Links under the hood. Check the Battery to ensure those Cables are all intact and there is no damage.

How can jumping a small relay damage a bater cable? They are good. When I checked the pcm for power it had no power to the appropriate slots
Automotive Expert
Because you're allowing 12 volts to go straight to ground bypassing the load. With the electronics in today's vehicle a Short to Ground can damage multiple circuits and control units. And it may be nothing more than one of the Fusible links.

Ok well I don't know where they are all atIf the pcm is shot can I get one from pick a part and put it in?I watched a bideo on checking the pcm and I did not have power to it.
Automotive Expert
OK, must have power to the PCM. Try checking "A & B" also check fuse #5 and #35. Let me know the results. Good luck!
Automotive Expert
That is the under hood fuse box.

All good no power accross 35 but is intactNo power to #35 with or without key onStill there

Fixed it.
Automotive Expert
Fantastic, so glad to hear!

What others are asking

Hello, I began to notice as I accelerate, sounds like air under the hood. The kind of sound you normally hear when driving through high wind. I don’t hear the sound until I accelerate past 45-50 mph. At first we thought it was the cv joint so we had it replaced. The noise is still there.

Glad to hear it! Do you have any follow-up questions about your Nissan Mechanics or would you like a second opinion on anything? It's included! I'd like to know if there is any way I can add Roy as a "favorite?" You can favorite Roy Sheidenberger to easily direct your future questions. Once you close our chat, I'll redirect you there. But if there's already something you want to ask, I can set up a new thread for you now? No other questions. Thanks! I'll see if Roy Sheidenberger is available to help. Before I go, are there any other details you'd like me to pass on? No. Just want to add him as a favorite.

You would need to check with a local exhaust shop for local laws on noise and if it is legal to do the exhaust from cat back with just straight pipes. Most states it is not legal.
