Question about 1994 Plymouth Grand Voyager

1994 Plymouth Grand Voyager 3.8 eng won't start

My 1994 Plymouth Grand Voyager stopped on me. I listened for the "whirl" of the fuel pump when I turned the key to "on" and didn't hear it.
I checked for voltage at the fuel pump before replacing and it was good. After replacing fuel pump it still doesn't start. Checked for spark at plugs and no spark from wires. Checked for spark at coil pack and no spark to wires. I disconnected neg battery cable when replacing pump so I don't think any codes would be available now.
Also, I have a Haynes service manual for this vehicle however, it's a bit unclear as to the exact location of crankshaft sensor, camshaft sensor, ignition module and where the computer itself is located.
Any assitance or suggestions would be greatly appreciated!
Thank you in advance.
David

Check primary voltage at ignition coil and fuel injectors, engine cranking, use a test lite, dark green wire with orange tracer. If no voltage, that comes from asd relay. Some makes and models if the computer doesn't see the cam and crank sensor signals, the computer won't ground the relay.
You need to do some testing.

SOURCE: 98 PLYMOUTH GRAND VOYAGER WONT START - BLOWS ENG FUSE - HELP

You have a shorted engine harness, this is not common but it does happen, heat and engine movement cause damage to the harness, this is most common on hi miler cars and vans, the only way to fix it is to start by looking anywhere the harness rubs, that is where the damage occurs.

SOURCE: on my 1994 plymouth voyager the 3 wire harness to fuel pump (blue wire) doesn't have 12 volts; should it? fuel pump quit then worked once when hot-wired with 12 volts. fuse and relay is good.

The wire should not be hot until the relay is triggered. The relay does not get triggered until the ignition key is turned on. It will run for 3-5 seconds or until the system pressure it at max.

SOURCE: plymouth acclaim wont start,no spark,no fuel

Do me a favor and cycle the key to on, then off, then on, then off, then back to on,& leave it in the on position.(not start) Now watch & record any flashes of the check engine light. You will get a number of flashes, then a pause, then more flashes. for example: 3 flashes, pause, then 3 more, would be code 33. It will always be a 2 digit number. 2 flashes,pause then 5 flashes, is code 25. When you get 5 flashes, pause then 5 more, that's code 55 which means end of message. Get back to us with any codes that flash.

Yes, I had this on my 97 Stratus....could be a couple of things....one, the there may be damage to the wire connector harness going to that sensor. That was the problem with mine. I replaced the cam sensor, crank sensor, coil pack, mas sensor..etc...it ended up being a burnt spot on the wire harness. They said this is a common problem for the stratus/breeze/cirrus/intrepid.....the most it could be is a bad ECM....there is a bad pin on it located half way down the side where the big connector is. It is the silver block with the big wire harness going to it in the engine compartment. Try wiggling that around...the harness area.

1992 Plymouth Grand Voyager won't start, fuel pump runs for about 1/2 second when you turn on the key


The power control module sends signal to the fuel pump relay, it gets it's signal from the pick up coil in the distributor and the crankshaft position sensor. I'm having the same issues with my 94 Jeep Wrangler

Changed water pump now 1998more plymouth grand voyager wont start


Check all your wires you removed. Obviously something is not connected. Check your ground wires first. When you have determined you have a good ground then check for power to the starter. If it cranks but won't start then you have disconnected something to the fuel or ignition system. If it ran before you changed the water pump then you have missed a connection somewhere.

My 93 plymouth voyager won't start unless I spray starting fluid down air cleaner, then it only runs a few seconds.


Listen for fuel pump when turning ignition to on position. If no pump sound, locate fuel pump fuse and relay in box under hood. First check fuse, then listen to relay while ignition is turned to on. Relay should click. If no click, replace relay. If click, circuits are good and pump is likely bad. Please reply if you have questions.
