I wish there was a way to test the PCM but there really isn't.

A PCM exchange really is probably your best option. You know it will work. It'll be programmed for your specific vehicle.

Good luck and keep us posted.

 

I lied about my last question. My final one is.. will later versions work with older?

Example: 03 dakota pcm in the 02?

Edit: After doing some more research I came across the engine coolant temp sensor possibly being a culprit. I DO in fact have a small leak which looks like it's coming from that sensor, not thinking anything of it. I read that the ECT can cause a no-start. So I'm off to Oreillys tomorrow morning for a quick replacement to see if it does the trick or not.

 

'03 was another transition year. Some vehicles have a 4 connector PCM and others 3.

You are limited to '01 or '02 (wiring wise). Really you should get an exact replacement.

 

I'm looking into just doing that.

I have a pretty decent leak around my thermostat housing after replacing the thermostat. It doesn't look like its coming from the thermostat itself though. Its filling up inside the actual housing.

Is the heater hose in between the thermostat and the coolant temp sensor?


I had an upper radiator hose blow out a couple weeks ago with coolant going everywhere. Is there a chance that the blowout caused a short somewhere around the engine due to coolant going everywhere?

Im trying to stray away from forking out some cash in the time being.

 

Coolant could have gotten into some connections, yes. You can get some electrical contact cleaner at your local parts store to clean any connections that you think got wet.

It sounds like the gasket may not be on the correct side of the thermostat, it's not placed properly, or the housing is warped.

The coolant temp sensor is in the intake manifold just behind the alternator.

 

Autocomputerexchange.net looks pretty ****ty on the customer review side. Who would you recommend?

 

ok any time the check engine light flashes it indicates possable cat damage do to skipping or ingition issues. this could be anything from bad power to an injector to a dead plug. bad wires. just go to advanced and have the code read and let us know what it is.

 

Alrighty, new computer installed. New problems.
No codes on the display when I switch on - off - on - off - on, but ABS blinks, and on the 3rd blink the engine light starts flashing.

Any idea?

 

So the "no bus" issue is fixed but you have something new.

Was the new PCM flashed with your VIN and mileage? My understanding is that if it isn't it can have "issues"

 

ahhh. No it wasn't. Im okay with a few issues in the meantime. I removed my ABS fuse due to the annoying constant chiming. Safe driver, so no ABS needed for me. After removing the abs the brake light came on. Is this a normal reaction to removing the ABS fuse?
