Help Me! 1999 Ford Escort LX problems - Ford Forums

turbo1.5 · 07-30-2007, 09:08

A buddy of mine has a 1999 Ford LX, it has 106,000 miles with the 2.0 sohc distributorless ignition system. One day his car wouldn't start and it has not started since. I tested the spark and there is none. I took out the fuel injectors and they are not squirting any fuel. The motor cranks over and I checked to make sure the cam is cranking over and it is (I.e. not a timinmg belt problem). I checked the emergency fuel shut off switch and it does not move as in it does not click on or off, the button does not move. I have been trying to help my friend out but I cannot figure out the problem. Please Help! Any advice would be much appreciated! Thanks

It's a 1999 Ford Escort by the way. The owner said he has been driving with the service engine light on for three years and has owned the car for eight years. He admitted to doing one regular oil change per year and has never changed the spark plugs. I'm not a Ford mechanic but this guy is my boss and wants me to try to fix it for him. I am very familiar with Hondas but this Ford stuff is quite different. ANY suggestions would be much appreciated!

No spark- check the coil pack
Fuel-- check the fuel ressure at the fuel rail. Can you hear the fuel pump come on?

Hi guys
I'm not quite sure I understand this...Did you say it has no spark AND no injection? Hook up a Noid Light to one of the injector connectors and see if it pulses when you crank. As far as I know the only thing short of an immobilizer that will cause no spark AND no fuel is the Crank Angle sensor or its wiring. It would also be great if you could scan it for codes...

I have not scanned for codes as I do not have a odb2 scanner. I was hoping there was a main relay or something that went out since there is no spark or fuel. If the tdc sensor is not working will the fuel pump not come on? And this emergency fuel shut off switch seems to be stuck down. But then again I don't know if it's supposed to be that way or not...

OK
If there's a main relay problem your car shouldn't even crank. The fuel inertia switch should be down when it's not triggered, so what you're seen is normal. A fuel inertia switch that has been triggered only disables fuel pump, NOT injector pulse or spark, that's why I mentioned hooking up a Noid Light.
If the Crank Position sensor is faulty there will be no injector pulse AND no spark because the PCM doesn't know where cylinder 1 Top Dead Centre is. You will however hear the fuel pump run when turning the ignition on but it will be disabled during cranking. Hope this makes it a bit easier. cheers

Thanks for all of your help! I am going to try a noid lite today. I am assuming you put the noid on the tdc sensor and see if there is a pulse, right? By the way I am not hearing the fuel pump come on at all!

I also checked all of the fuses and found nothing blown

Disconnect one of the injectors and hook up the light to that plug. It should pulse as you crank. I don't think you can hook it up to the sensor as there will be 3 pins as opposed to 2 in the noid light.cheers

So I replaced the cylinder position sensor and still the car will not start. The injector plugs on this escort have two wires per injector and the cylinder position has two wires as well. Any ideas? If I test for a pulse and find out that there is no pulse, what could be problem then?
