92 wagon just stop running

[gajuggalos]

K here what happen was on a trip and it just stop while going down the highway. took th fuel line off and turn the key no gas flow. Replaced the fuel pump,filter and screen. Ran for about thirty minutes then stoped again. So I changed the fuel pressure regulater and that did not work. Got a code scanner and it give me the pass code of 111. It is getting spark the injectors are getting power but not sure they are pumping gas. Any clues of what this might be before i shell out anymore money of parts that don't need replacing. but still thinking the EEC has gone bad. Any help will be most greatful.

when your car dies out does it lose total power from the battery? The reason I ask is because I had a similar problem my car completely quit after running a short while. I found out that the battery wasn't making a great connection and when it warmed up it would totally lose power because the heat from the power loss opened the connection on the terminal so there was little connection with somethings working and others like power windows dead.

It may not be a fix to your problem just a suggestion

No Battery runs down after trying to start it. but thanks anyway.

I have taken the fuel rail off. the repair manual says that when the key is turned on that it is supposed to spray three times per injector but nothing happens when key is turned on.

All injectors fire when you turn the motor over. Any one wheather it may be possiable that it jump timing?

1st I would check ALL of your fuses, it may sound silly but always K.I.S.S (Keep it simple stupid) you would be amazed at how many times crazy problems like this are caused by a bad fuse or relay.

2nd I would check the Fuel pump relay. Make sure there is power and ground going to it when the key is on.

3rd I would check for power in and out of the Inertia switch (should be located in the trunk on the pass side of the car). It should have 2 wires going to it (Red and Green). Make sure the red button is depressed all the way and check for power on both wires with the key on (must be connected to inertia switch).

If this doesnt help, its time to get under the car with a DVOM (Digital multimeter) and check for Batt voltage at the fuel pump with the key on.

have check the inertia switch and all fuses. Not sure where the fuel relay is located. I have the tank droped from where i rechecked the wires for a short. The fuel pump wil prime itself eveytime the key is turned on. And there is good pressure at the fuel rail. Have check all hose that can be seen even under the battery. I have ran out of things to check. Just don't understand how when I change the fuel pump out it started running for a few then stoped again. what should the volt meter read at the pump? I will give that a shot. Want to check all areas before buying a new EEC to see if that will work.

Check your throttle linkage and throttle position sensor for looseness or up and down play. If this sensor is bad or giving an incorrect output it can shut down your injectors.

Thought you said in the original post you had no fuel flow? If you have PSI at the rail, you should check to see if your injectors are getting a pulse. Hook a test light up to ground and check the injector for power with the key on. Then hook the test lead up to battery power and check to see if your getting a pulsing ground signal to the injector (with eng cranking). If your not getting a pulsing ground signal I would suspect a faulty CAM sensor.

When you hook up the DVOM at the fuel pump you should see battery voltage (12.6). It should come on for about 10 seconds to prime the system and cut out. Have someone cycle the key on and off for you.

[gajuggalos]

the fuel pump will prime itself and the injectors are getting a pulse. I've checked everything i could think of. the coil. distribitor cap plugs and wires. All are fine. Damn I miss my 78 olds cutless. LOL If it was a cam senser wouldn't I get a code with the code scanner.

[SCPDMechanic]

If there is pressure in the rail (30-45psi), Power and a cycling ground (pulse) to the injectors, and it isn't starting...........your problem isn't in the fuel delivery system.

Have you tried spraying Ether down the air intake and seeing if it starts?

Have you checked for spark?

[gajuggalos]

have not check the psi trying to get a gauge. But when starting fluid is spay in the the intake manifold it starts right up.

one more thing my brother told me it might be my map sensor. Went looking for it and there is not one where the book says it should be. Book is a Haynes repair manual. Starting not to like this book. Can anyone tell me if I even have a map sensor?

[SCPDMechanic]

I believe your car is only equipped with a MAF (mass air flow). If you suspect the MAF you could disconnect it and see if the problem clears, I highly doubt this is your problem though. Usually when MAF/MAP sensors go, the car will still run. Try and find out what the PSI is at the fuel rail..... this is pretty important. You may have 6lbs there..... not enough to run that car.
