1994 Ford Thunderbird Won't Start

Engine Performance problem
1994 Ford Thunderbird V8 Two Wheel Drive Automatic 26,000 miles

I drove my car last week with no problems. Today I went out to start the car and it will not start. It has 1/2 tank of gas. It turns over but seems as no spark is getting to the plugs. What should I do or where should I start looking for the problem.

Do you
have the same problem?

First thing I would check is the fuel pump. Mine did the same thing last Saturday- I moved it on Thursday with a full tank of gas and tried to move it on Saturday and would not start.

The easiest way I found to check if it is a fuel pump or filter is to disconnect the fuel line going into the fuel rail. You will need a quick disconnect tool (not too expensive at your local parts store, like $10 for a set.) Do not try to disconnect it without this tool, you can damage the line and spend a lot to replace it.

Disconnect the larger diameter line that sits right above the passenger side valve cover. There is also the return line, make sure you get the right one. Mine was wire braid and the return wasn't if that helps.

Once disconnected turn the key to "on", it is not necessary to run the starter because the "on" position will have a primer cycle for the pump (it runs for about 2 seconds). I just watch through the opened hood at the bottom of the windshield. If fuel sprays out it isn't the pump.

If fuel doesn't sprays out, check the fuse - I think it is F13 in the main fuse box under the hood. If that is okay I would change the filter (which will also require the quick disconnect tool).

If that doesn't fix it you will have to change the pump. You can do it in your garage (I have twice) but it isn't fun.

Let me know if you have any other questions, I might be able to help.

Good luck,
