2003 Mach 1 Died While Driving. Now Cranks but Won't Start. - 2003-04 Mach 1 Registry Owners Club

Hicompression · 12-12-2015, 06:29 PM

Okay...so today, my 2003 Mach 1 with 109K miles died on me when I was driving normally. Pulled out of a store parking lot and the car hesitated...I let off the gas and was coasting to a red light. The car started to idle low then died at the light.

The car would crank but would not turn over. People started honking at me as I let off the brake when the light turned green and luckily started coasting (downhill) across traffic to the shoulder.

Again car would crank (smelled rich) but absolutely would not fire and run. It tried a couple times but it barely caught and then idled really low and died.

So what could be the problem? I had the car flat-bedded home and it is now in the garage. Car seemed to be running fine right up until this event. I'm thinking something catastrophically failed in the electrical system. Help!

Can you hear the fuel pump turn on when you turn the key

Hicompression · 12-12-2015, 07:58 PM

Yep...and you can smell gas too when cranking it.

canadianmach1 · 12-12-2015, 09:59 PM

Did your check engine light come on ?

Hicompression · 12-12-2015, 10:30 PM

Nope. Just bogged, caught, bogged again and then died. Would not restart.

canadianmach1 · 12-13-2015, 12:03 AM

I would check for fuel pressure to be sure. If you have if pull a plug check for spark and make sure they are dry and not full of fuel. If it all looks good put it back together. Pull the connector off of the mass airflow sensor and try to restart .

Checked with my code reader to see if there any codes = none. Tried restarting this morning...still cranks but won't start.

I'll check the fuel pressure as you suggest at the fuel rail fitting. I'm assuming gas will squirt out if there is pressure. If nothing, you may be right, my fuel pump may be dead.

I also tried a different key to make sure it wasn't the PATS system. It's not.

After I check the fuel pressure and if there's pressure, I'll check the MAF by pulling the connector.

Cumbersome101 · 12-13-2015, 05:00 PM

How many miles on it? Is there anything u have done that might have caused this? Has the vehicle acted strangely any at all before this happened. Any unusal noises when u r cranking it?

Hicompression · 12-13-2015, 05:30 PM

It is in fact the fuel pump. Just finished checking. Absolutely no fuel pressure at the schrader valve on the passenger side rail.

So...does anyone have the part number for the SVT Focus "green-top" pump? Or...any other recommendations for a replacement? As I stated in my original post, this car has 109K miles. So...a bad fuel pump...not totally unexpected.

canadianmach1 · 12-13-2015, 05:49 PM

you should first check the fuse for the pump, and the inertia switch in the trunk , or the best thing would be to make sure you have power going to the fuel pump with the connector under the car going to the pumps.

Hicompression · 12-13-2015, 06:23 PM

I checked the fuel pump fuse in the fuse block under the hood and I checked the inertia switch in the trunk. Both are good.

canadianmach1 · 12-13-2015, 06:31 PM

I would still make sure you have power at the pump, its probably the pump, but to be sure and not just throw parts at it, that is what I would do.

I am having the same problems currently, i just replaced the fuel pump and it still won't run, i have done some reading and thinking maybe crank positioning sensor, please keep me posted if you resolve this problem

01yellerCobra · 12-16-2015, 07:53 PM

Pull the vacuum line to the FRPS. See if there's gas or a gas smell in it.

I had a similar problem with my 03 automatic. New IAC valve solved my problem.

fuel rail pressure sensor cured mine

jbrad88 · 12-23-2015, 08:29 PM

Constant Control Relay Module...or CCRM...

Controls fuel pump, fans, and ECM...inside the passenger fender

Hicompression · 01-13-2016, 12:36 PM

Sorry...been a while since I posted. I was out of town over Christmas and wasn't able to do anything with the car. Also, bought a new BBK fuel pump unit off of Amazon. The first one they sent me had a cracked plastic casing...so I had to send it back and wait for them to ship me another.

I plan on replacing it soon. We shall see if this cures the problem.

FordMan · 01-13-2016, 03:57 PM

I was going to take mine in for the required state inspection late last month and while driving it around the block it stumbled and barely made it back home before dying. Had to leave it parked in the street (don't like to do that) in front of the house, where reading the codes showed a fuel issue and O2 sensor malfunctions. The onboard A/F gauge showed it running pig rich.

Failed to start thereafter, so I started with the relatively easy things (fuel filter, air filter) and worked up from there. Changed the fuel pump drive module to no avail, changing the fuel rail pressure sensor got it to start but still running pig rich. At least got it back into my garage under its own power where I can next replace the O2 sensors, out of the elements.

do you have a tuner? if so turn off the o2 sensors and see what happens.

is the BBK a plug and play?

Yes I have a Diablo Predator handheld tuner that can perform that function. If I understand correctly though it would only turn off the rear (downstream) sensors and not affect those ahead of the cats.

Yes. It's the whole assembly with the fuel pump wiring harness pigtail...not just the pump.

Hicompression · 03-05-2016, 06:25 PM

Don't you guys just hate it when someone asks a Technical Question and gets suggestions as to what the fix/problem is but then leaves the thread open-ended without ever replying back with a conclusion? Yeah, me too...

That's why I am happy to report that today...several months later...I got the gumption to change out the stock fuel pump for my brand new BBK unit. It was a beautiful sunny day around 75°F so I didn't mind working on my back on the concrete floor of my garage.

The BBK unit was a direct fit. She fired right up after I dropped the tank, swapped out the old pump and got everything back together. Problem solved!
