92 Voyager Will Not start

IFIXTRUKS · #1 01-12-2005, 11:41 AM

Hi, I've been working on a 92 Plymouth voyager 3.3 that will not start. It cranks fine...engine turns over.

Here is what I've checked so far. The fuel pump does not run at all when you turn the key on, does not pump any fuel. I checked the wires going to the fuel pump and the supply feed for the pump is shorted directly to ground....unable to locate short. I cut the wire and bypassed it by running 12 volts to it. When I did that the fuel pump will pump plenty of fuel and has good pressure at the fuel rail.

Problem 2...After getting fuel pressure to the fuel rail...the van still will not start.

Pulled two plugs and no spark at either while cranking. I have changed the engine control with one from a running vehicle and still nothing. Same as before.

I've read about an auto shutdown relay. But not sure what causes that to activate. I've checked all relays with ohmeter and all relays are good. I've done some wire tracing and found one red wire right below the batter that was corroded. I've repaired that wire.

Is there any other tests that I can do with a volt meter to help diagose my problem. Is it possible to test the crank and cam postion sensors with a volt/ohm meter..I have been unable to find the specs for these sensors. Any help is greatly appreciated.

I am having the same exact problem with a 1994 caravan with a 3.3 .

After 10 people told me that it was the crank position sensor...I felt I was at a dead end and it couldn't hurt anything put my pocket. I bought a crank sensor and installed it. NO DIFFERENCE still having the same problem.

check the PCM for trouble codes by turning your ignition key on/off three times ending in the off position. Read whatever codes it spits out from the check engine light. If it flashes the "check engine" light twice pauses then flashes another four times, that's a code 24. When you find out what codes you have (if any) let me, I can try to help you. Just a little FYI, if you cam sensor was bad, your fuel pump wouldn't work; cam sensors control fuel syncronization; It's somewhat expensive but the next option could be the ignition control module which is mounted on the engine by the thermostat housing.

Thanks for the reply. I have tried to get flash codes from this van but there are never any codes. I do mean zero...it does not flash the check engine light at all. I know the bulb in the dash is good because it comes on when you first turn the key on. I have changed the Engine Control over on the driver side fender next to the battery with one from a running van of same year/engine. I still could not get it to flash the check engine light.

Isn't it at least supposed to flash a code letting you know there are no codes?

Is there a way to check the Cam Sensor with an ohm meter or do you have to check it via a scanner?

Thanks in advance for any input.

Here are the codes for the 92, and instructions to get them.

It should flash 55 at the very least, if there is absolutely nothing wrong. I almost always see at least 12 and 55, but that may be because my first impulse with problems on these is to disconnect the battery

It doesn't flash any codes at all. Here is what I get with your link....

I just checked the link, and it's still up. You may have a hijacker on your computer. If you still can't get there, let me know, I will post the text here.

IFIXTRUKS · #10 01-20-2005, 03:33 PM

ok, the link is working now....but this is something that I already knew.

I'm not getting any codes to flash. 0 The bulb in the dash is good It comes on for a few seconds when I first turn the key on....but with the on,off,on,off,on sequence I am not getting any flash codes.

Any thoughts or suggestions?

HiRez_L · #11 01-20-2005, 03:45 PM

My only thought would be that whichever computer drives the codes and display has a problem. Have you checked for good ground and firm plug-ins on all the under-hood modules?

Force a code 12 by disconnecting the negative cable to your battery, waiting 10 minutes and reconnecting it. Then retry the ON-OFF-ON-OFF-ON sequence with your key. Make sure that your key stays in the third and final ON position... you should then get a 12 and 55. If not, there is a problem elsewhere.

If you don't have an OBD reader, Auto Zone might have one and, if they do, they will check your Caravan for free. If your onboard diagnostics is toast, you may have microprocessor or chip issues that must be resolved.

I did exactly what you said. I do not get 12 and 55. I do not get any codes to flash at all. The van won't start to get it to Auto Zone. I'm assuming since I can't get any flash codes that they wouldn't be able to read the codes either. I tried with a different computer from same make model van...still no codes. I'm guessing I have a problem in the harness somwhere.

The harnesses that run under the battery tray seem to have regular troubles on these, I'd start looking there.

I have a 96 grand voyager and it will crank but not fire. I replaced the coil pack. When I checked for spark I had none while the battery was cranking at full charge. As the battery began to run down I started to get a spark and it sounded like it was trying to fire. Any ideas?
