Very possibly yes....could also be a mechanical leakdown on the pump itself in the tank....best test would be to do a mechanical pressure gauge and see the fuel pressure drop with applied power to it or not

Probably lost either spark or fuel to the engine. Try starting it with starting fluid into the intake. If nothing happens, check for spark on a spark plug wire- probably the ignition system. If it runs for a second or two with starting fluid, it is a fuel problem-check fuel pressure to see if the fuel pump is still working.

2000 mercury grand marquis 4.6 Intermittent problem. 35,000. miles. Problem engine died several times wile driving. Also after car is parked from a drive will not start. Found that the fuel pump is not...


I'd have to test when problem is ongoing. When you first turn on key, no crank, you should hear the pump run for a few seconds then stop. For initial prime, the computer doesn't need rpm signal. Engine cranking, the computer needs to see rpm signal or it won't ground the fuel pump relay. W/o rpm signal, no spark at the plugs and no fuel injector pulse. I know your talking about fuel, but, when problem is ongoing, check spark and fuel injector pulse, engine cranking.
Intermittent problems are a pain, have to test when problem is ongoing.

95 lincoln cont. occassional crank fast ,but no start ,intermittent ,later will instantly start as should


I think what you have going on here is a failing electric fuel pump, this is what they do when they are worn out, it is a rotary pump and the rotor sticks due to worn bearings. To confirm this get a can of spray starting fluid from any auto parts store, next time it won't start spray it into the air intake hose to the engine, if it fires right up you have a bad pump. The fuel pump is located inside the fuel tank, remember to also replace the fuel filter when the pump is replaced. Also check the connector to the fuel pump cutoff safety switch for signs of melting, replace the switch and connector as needed, this is caused by a defective fuel pump drawing excessive current.

93 ZJ 4.0L has intermittent fuel-pressure drop when starting


You have a good theory but haven't finished testing so you can verify it...check actual fuel delivery when in no-start...also probe the pump wire on the pump side of the harness and see if you are in fact not getting power to the pump all the time. (also in no-start). Don't test after it gets started, or testing will tell you what you already know...It runs fine once started...tests will then tell you it's fine (you know it's not) Problem itself could be anything from a bad connection somewhere to a balky pump.

I thing it is definitely the fuel relay. I had the same problem. The relay is quite big and it is located and bolted under the dash on the driver side, brown in color. You can't miss it.
