#103 of 116 Lincoln Turns over but does not start
Oct 12, 2012 (5:37 am)
The symptoms: The car sat for six months. I connected the battery. It would turn over but not start. I sprayed some starting fluid and it started. Occasionally, I would have to use starting fluid to start it. I thought it was old fuel working its way through. Now, It won't start. The fluid starts it for two seconds and then dead. I noticed the battery is low, so I charged it. Same thing with the starting fluid. Two seconds and dead.

Well after 6 months you probably have rotten gas, but I can't say for sure. You might check for fuel flow from the fuel pump by either disconnecting a line or by installing a fuel pressure gauge.
If you do have fuel flow but won't start without starting fluid, then either it is indeed rotten gas or your fuel injectors are not getting a pulse. In that case, you'll need to buy an inexpensive "NOID" light and test for fuel injector pulse from the car's computer system.

I fixed it. It was the primary fuel pump. I started with the filter, but no gas was going to the filter. And I couldn't hear the sweet hum of the pump.
Ford/Jaguar was nice enough, in this case, to locate access under the passenger's side rear seat. It comes up. Look for two tabs under the front crease. Slide them and the seat comes up. Slide the backseat to the side. Lift up the vinyl and you will see a 6 inch rubber Tab. Remove that and there is the top of the fuel pump case. Before you proceed, go to Auto Zone and buy the new fuel pump. It will have instruction on how to swap it out. Good luck with those fuel line connectors. They are a beoch. Also, I used a hammer and a 3/4" piece of pvc pipe to remove the ring at the top. If you have a better idea, please post.
Buy the pump at Auto Zone, because it includes the two sump filters. O'Reily wants to charge you extra for them.
Some articles say there are two fuel filters in the LS. Actually there are three. Two in the tank and one behind the driver's side tire.

I'd get rid of that gas, or at least swap out the fuel filter pronto and add fresh fuel immediately.

I drove the car all night. It's like its new. No more missing. No more engine light. Everyone should swap out their old fuel pump, just for fun.

Ah, the proactive stance!
But change the filter, just for laughs.
#109 of 116 Cranks but won't start right away, then runs fine???
Dec 10, 2013 (8:41 pm)
I've been away for a while, but happy to see some of the original members from the beginning still here.
2000 Lincoln LS V8 Sport, 100,000mi, Feb 2000 build date, had since new. I still love this car!
Searched the forums and couldn't find the following exact symptoms. 2 years ago had a no start event. Starter turns fine, but engine doesn't fire. After 6-8 tries, it fired and started. No gas smell, seemed like it just wasn't getting fuel. Then it runs perfectly, like nothing happened. Good power even at full throttle acceleration.
Happened a second time about 2 months ago. Then 3 weeks ago. Then 2 weeks ago the battery ran low before it would start. Missed a dentist's appointment that time, it started 30 minutes later. Tried the following to no avail… gas pedal floored; gas pedal jazzed; lock and unlock doors a few times with fob; disconnect and reconnect battery; turn key slowly; turn key fast, start in neutral and park, then it just starts when it feels like it. Connectors on fuel pump under Px rear seat are clean and not corroded. Always happens on a cold start, not when engine is warm.
No fault codes in the OBD - had a smog test a few weeks ago and they said it was all good.
Replaced fuel pump relay in trunk with similar fog light relay under hood, but it still did the no start thing, so it's not that. I can't be sure because of other noises, but it seems like the fuel pump doesn't run for the second or two like it should when the key is turned, when I have the problem. I'll peel the seat back so I can hear more clearly next time. I'm suspecting the fuel pump, but I'm bothered by the fact that it runs perfectly at all other times - it's like intermittently the pump isn't getting the signal to turn on. Has anybody out there seen a fuel pump failure in this manner? Any other suggestions? Because it's intermittent, and the dealer is 30 mins away, it's iffy that the problem will happen at the dealer's. I don't want to replace the fuel pump and still have the problem, either.
I might wire a voltmeter in parallel with the fuel pump to confirm it's getting voltage when the problem happens. Comments or your experiences appreciated.
Thanks - markls8.

One of the numerous things I had to replace on my '00 LS (sold a year ago with 128K miles on it) was the fuel pump. That's what it sounds like to me.

Aren't there 2 fuel pumps? That's what it sounds like.

Ah- replies from two other charter forum members, it's been years and I remember both of you guys, akirby and cdnpinhead, nice to hear from you both. Sorry to hear you sold yours, cdnpinhead, it's the last performance vehicle Lincoln put out, everything else is FWD... so what's in your stable now?
I think the Px side pump is the main pump to the engine, and the other one pumps fuel from the driver's side to the Px side of the fuel tank (“jet” pump). There might be a third under the hood, IIRC.
It's the main pump that doesn't run for a second when the key is turned (when it should), I can hear it run and predict that the car will start, and when I can't hear it run, I know the car won't be starting. So I can now tell whether it will be starting or not without engaging the starter and using the battery unnecessarily.
The voltmeter idea didn't work, presumably because the switching is done through the grounds on these cars.
I've made arrangements to have the car towed when it's in a no-start condition for diagnosis. The owner of the garage once owned a 2001 LS and worked at a Ford dealership for a while and seems confident he can locate the problem point.
Thanks for your replies, if others have replaced theirs and it solved the problem, that makes it more likely that mine will be the same, will let you know what happens, should know within a couple of weeks, it's more frequent now. (Yeah, right when we got hit by a snowstorm).
