Question about Buick Rendezvous
It definitely sounds like an electrical problem. You should add more details to narrow the search.....such as it works sometimes.....or it is worse on humid or rainy days. These kind of details would indicate a faulty, or dirty connection. It does sound like the first place to start would be the ECU or main computer. I myself would disconnect the connectors in and out of that black box. Then I would spray them with electrical cleaner/lubricant then see if that helps. Of course swapping out a known good ECU would really help, but returning one of those could be problematic if that didnt cure your problem. If it is the humidity because of the change of seasons.....try letting the car dry out in the sun with the doors open.

SOURCE: gages work sometimes
Hi! Check the circuit that controlled the gauges,it sounds as if u are having a slack connection some where.This could be bad ,for slack connection generates heat which could lead to burning of the circuit.

It seems that if you tried that many brain boxes, one of them would have worked.
Here are some things to check. (I am assuming you have gas in the tank, the battery is good and the engine cranks over but doesn't catch and run.) Perhaps one of these items was overlooked in the trouble-shooting:
Engine cranks but won't start:
Charcoal canister full of fuel, faulty MAP or MAF sensor, faulty engine coolant temp sensor, faulty EVAP canister vent valve, EGR valve stuck open, lack of or incorrect fuel pressure (fuel filter, fuel pump, fuel pump relay), water in fuel, fouled spark plugs, faulty ignition module, severe vacuum leak, severely clogged fuel injectors, wrong size o-rings on fuel injectors (prevents compression), faulty airflow sensor (if equipped), Idle Air Control (IAC) valve defective, disconnected-broken-loose wires for all of the above.

The security light is a visual indication that something in the car's antitheft system is failing. In most
GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you
put your key in the ignition, there begins a constant line of communication between your key's security
chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module).
These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending
signals to each other. The security light illuminates when that signal gets broken, even just for a second.
When the signal breaks, the car misinterperates this as an attempt at theft and goes into antitheft mode.
The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key.
This is why the security light turns on and shuts down your vehicle. Remember too, the TDM controls the
security light. Sometimes you can have ALL the symptoms and no lights. This link explains it pretty well.

SOURCE: brain box problem
Hello Bright, I won't even begin to act like I know what a brain box is, but I would say if the car means as much to you as you sound like it does. Then have another Auto Electrician have a look at it or troubleshoot the problem yourself. A good electrical repair manual found online from Mitsubishi will most likely tell you how you can verify the report given by the first electrician. I myself would just rather have the "no fuss, no gadget electronic system in a vehicle. Give me the cars from the 60's to the mid to late 70's." I am one happy camper then! You know the 62NOVA, 65Pontiac GTO, 68 Chevelle Mailbu and let's not omit the 69 Judge and Super Bee. Those are cars to work on Ssswwweeeeeeeetttttt!!! Good luck

did the check engine light tell you there was a pcm fault or something else before you did the swap? Alot of things can cause a no start. A bad crank position sensor(CKP) cam position sensor(CMP) fuel pump. My brother-in-law did that to a dynasty and turned out to be a broken wire on the CKP circuit.
