Was the check engine light on when it quit running? Also need to find out if there is a signal to the injectors. You can plug a 194 bulb into the injector connector and it should flash when you try to start the car. If it does not flash, need to possibly check or a bad ignition module or cam sensor.

SOURCE: Car starts then immediately idles down and shuts off

i have had the same problem at times. my car would start and then shut off. but i found that i needed oil and check my oil and it was a quater low put in some oil and everything went fine i notices that everytime the oil is low the same thing happens also depending on the position of the car being park meaning that if you are in a down hill position or up hill position i will do the same. so you have to accelarate for 1 minute to have the oil go up. i hope this works

Apollo, I would first pull all the plugs out and give a little squirt of something like seafoam or even just a bit of engine oil into each cylinder, you may have lost the seal between the rings and cylinder walls and this will help. You also need to confim for shure that you are not getting fuel before you worry about the pump. You can check this at the fuel rail, either by opening up the line, or in some cases you may even have a schrader vale(like a tire valve) on the line that you can press. I suspect that you do have fuel, but the injectors are not oppening due to the old fuel sitting in them for so long. These can be removed and taken to a shop that cleans injectors, and then reinstalled with new seals. And yes I do belive that there is a fuel pump relay in the fuse area, you need to do a search to find out wich one. These can be jumpered to activate, but untill you have done everything else i wouldn't worry about it. Oh, I asume that you have checked for spark? If not, you can pull a plug out and with the wire attached you can hold the base of the plug against the block, while wearing gloves, and see if you get a spark when some one cranks it over. Remember, you must have spark, compression and fuel at the right time in the proper ammount, and it will run.

SOURCE: The car cranks but won't start. There is no spark,

If you remove the fuel line and crank the engine and get fuel then you could be assured that the crank sensor works but if there is no fuel while cranking then the crank sensor is most likely the fault. If the crank sensor is not the problem then it is most likely in the coil or distributor which the 97 is notorious for.

1984 Chrysler new Yorker 2.6l wont start. Replaced the fuel filter, new spark plugs and wires, new fuel shut off switch, new relay delay fuse, and a new ignition coil, oh yeah and a new starter. Ever hear...


Here's a quote from amy Chilton's manual for 1980-1987.

"Several types of fuel filters are used. One is located in the fuel tank of all the vehicles and is part of the fuel guage assembly. Second is a sealed paper element, in-line unit; mechanical system- located on the engine (above the fuel pump) or electrical system- located in front of the fuel tank. Third is a paper element, in-line fuel filter/vapor separator, housed in a fuel resevoir. Normally, the in-tank filter does not require changing. If it does, the fuel tank must be removed. "
This thing you describe sounds like the typical Chrysler in-line filter of its day. It is nothing more than the same generic in-line plastic see-thru filter you buy for your lawn mower except in the 70's and 80's it was covered in metal and had a Chrysler part number. A lot of guys added an extra filter in those days, it wasn't the best system. I would remove the outlet line and turn the fuel pump on, see if you get fuel. Replace if needed.

Good explanation of symptoms.Thank you.




No assumptions.
Diagnose problem.
Pinch off the fuel return line.
Check fuel pressure--I don't wanna!PITA!
The fuel pump won't run if the fuel filter is plugged up.
Toyota's have a gas tank drain plug!!!!!!!!!
My '84 takes a 3/8 " ratchet. Cool.

There may be a fuel pump relay that is toast,but I suspect the filter,off hand.
A plugged filter will overwork the pump and cause the engine to run rich.

As you have probably figured out by now, you will have to treat it as a no start and troubleshoot it when it fails to start. Until you figure out if you are loosing spark or fuel to the injectors when the engine dies you have no direction to go in.

Wont start


I understand you replaced the relay but not the pump, right ?
Has the fuel filter been replaced recently ? Are you sure there is gas in the tank ?
You should be able to jumper the pump relay and check fuel pressure.

Truck will not start when cold - like if not getting gas till several starting attempt and pumping at time the gas pedal.


couple of possibilities; 1) clogged fuel filter 2) Fuel pump going bad not holding pressure. (it drains back overnight or after shut down)

I can't hear the fuel pump working when I try to start the car. The car turn over to crank just fine, but as soon as it cranks it shuts off, if it cranks at all. As soon as I mash the gas pedal it goes...


Check the fuel pump relay and if is good then more than likely the pump has failed on this 16 year old car and needs replacing. The relay is under the hood on the passenger side, front of the engine, rear of the headlight housing, mounted on the upper part of the fender well, in the relay block.

if you believe some one put water or bad gas in your tank, then you will have to drain the tank. however, to know if you have water in your gas, first disconnect fuel return line or the line that goes in to the fuel pressure regulator put some fuel in a clear glass and let it sit for 15min.if you see white cloud at the bottom of the glass or water. drain the tank. if not check for spark by removing one spark plug wire and spark plug. place the spark plug in the spark plug wire boot and touch it on the metal part of the car. do not touch the spark plug itself only the booth with the plug in the boot. have some one crank the car over. if you see spark, the spark part is ok. but if no spark, check the coil with a volt meter it should be 3 to 8 ohm if not replace the coil. if ok, check for fuel by removing one spark plug or two and see if they are wet,if wet pump is ok. if not check the fuel pump relay and fuse. if fuse is blown replace. check relay with a volt meter. resistance of the relay should be between 40 to 80 ohm. not mega ohm,if mega ohm, replace. if not , listen to the fuel pump while some one is cranking the car. if you donot hear the pump, disconnect the pump electrical connector and applive 12 volt and ground to the pump by using a jumper or any wire and listen for pump sound. if not replace the pump. if there is sound coming from the pump, it is ok. check the fuel pressure regulator with a fuel pressure gauge or simply disconnect the vaccum from the regulator and try starting the car. if fuel pump is ok and spark is ok. then it maybe the computer or the crank position signal. also check the fuel filter it may be clog.
