Question about Buick Cars & Trucks

2 Answers

I have a 2003 Buick rendezvous cranks but no start I've checked the fuel pump and have pressure fuel pump is turning on fuel filters are good I've checked for vacuum leaks and found nothing and I replace the spark plugs and wires and still nothing. I had put a aftermarket radio in about a month ago and when doing so had some problems with a wire that kept telling me security on the dash so I ended up leaving that wire un hooked up to anything. It ran it drove fine for about 3 weeks and I come home from work one day and turned it off got up the next morning to go to work and it won't start so like I said it cranks but will not start I don't know what to do next

You need to eliminate 3 possible variables that are leading to this problem. Any engine only needs 3 things to run- Air, Fuel, and Spark. This applies to small engines, all automotive engines, etc. A diesel differs some but that doesn’t matter here. You need to check for spark, do so by removing a spark plug(the easiest one you can access) and then plug it into the plug wire as normal, hold the metal of the spark plug against the engine block to ground it and have a friend or girlfriend, wife, brother, grandma or just anyone hold the key in the start position to turn the motor over- you should clearly see a spark between the body and the electrode of the spark plug, move it around some of you don’t see it at first to ensure a proper ground, if you don’t see spark that’s your issue. It sounds like you have fuel, Air should be no issue unless the intake system or air filter is clogged which is possible but unlikely. Is there a check engine light on?

I wouldn’t be surprised if you may have interfered with the anti-theft system and that’s causing this issue, since you mentioned the stereo installation, maybe not an issue at all but if no spark is present you should take another look at that, and get a free diagnostic scan from a local parts store, call a friend with a scanner, or do something to confirm what’s wrong before buying parts blindly.

My friend just had a very similar issue, a local garage said crankshaft position sensor, then mass air flow sensor, do a tune up, blah blah blah. I hooked up a scanner that set me back a whopping $30 which pairs to my iPhone via Bluetooth and was able to quickly determine the issue was an ignition related one, he wasted $400 per the Local Garage’s advice, it was a simple $26 fix as it simply needed plugs and wires. I’m just saying, don’t thriw parts at it and waste money unless you’re a rich man Unlike myself and it doesn’t matter, lol. Good Luck and You’ll Get it, you’re obviously ahead of many as you know a bit about troubleshooting.

SOURCE: Vehicle dies while driving down the road.

could it be the A/C pump kicking in. might be boging down the motor or electrical circuit, not letting the injectors get enough power. This could happen if the bearings are going bad in th A/C pump or there is a short in it. Just an idea. sounds like you have done the main components.

SOURCE: My 1991 Audi 80 will not start, engine cranks

Sounds to me like you may have left the air temp sensor or something electronic disconnected - Distributor - MAF sensor - go back and check and make sure that there's not an electrical pigtail somewhere hanging off - a vacuum leak wouldn't keep it from starting unless it were major - and your AUDI is mechanical injection I think - so fuel pull isn't a problem - check those connectors - let me know??? Thanks

SOURCE: 1997 saab 9000cs 2.3t won't start;2 days ago

Just a thought. How low was the tank when you filled up. I know alot of sediment builds up and have heard of similar problems. So I have made a habbit not to go below 1/4 tank to prevent from clogging the fuel system. That is what I would check. It sound like you have a good hold on the mechanical aspect. Verify your fuel inlet screen at the tank or the filter is not clogged. Only other thing I can reccomend after that is have a reputable shop do a systematic pressure check on the lines starting from the fuel source. Good luck.

2003 rendezvous fuel pump reset switch location


GM doesn't use an inertia switch, that I'm aware of. I don't know what testing you have done? Engine cranking, do you have spark at the plugs and fuel injector pulse? Any applicable trouble codes? If through your testing you have narrowed it down to fuel system, note the diagram.

2003 Buick rendezvous.turns over will not start. Replaced fuel pump,both crank sensors,timing chain,plugs, wires,fuel pressure regulator. What else need I check?


Did you check the oil? This vehicle has a low oil sensor that will disable the ignition if more than a quart low. Check for blown fuel pump fuse. Check for bad fuel pump relay. Never replace this many parts without first performing an OBDII scan. The stored fault history is always your guide to part replacement. You have replaced a lot of expensive parts that you probably did not need. Always try the cheapest fixes first. OBDII scan is free at Autozone. GM vehicles are prone to Anti-Theft function that can disable the ignition (Not reading the chip in the key). The OBDII scan will show these problems too. Also reset the Rollover safety switch, it can disable fuel pump function.

My 02' Buick Rendezvous cranks too long or doesn't start if you turn the key from the off position to the start position immediately without waiting in the accessory/on position for about 2-3 sec.


Check your fuel pressure, it sounds like your fuel pump is slow to build up the pressure, or maybe pressure regulator is not holding fuel pressure the way it should.

Changed the fuel pump on 2002 rendezvous and battery radio is locked and car won't start


Did you check for fuel pressure with a fuel pressure gauge before replacing fuel pump ? Did you test for spark ? Is there compression . Is the security light lit on the instrument cluster ? anti-theft system stops injectors from working if a problem is present. You changed the battery ? Battery Disconnect or Replacement Problems

2003 Buick Rendezvous turning over, sometimes starts and sometimes won't, brand new battery?


How long since a tune-up? Check for applicable trouble codes. Some of the national brand auto stores will check codes for free.
Have to test when problem is ongoing, if it cranks good, but won't start, have a helper crank it while you check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse.
With intermittent issues, you have to test when problem is ongoing.

I have a 2003 Buick rendezvous won't start turn over plus it gets hot


If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure, also, check fuel injector pulse, engine cranking.

As far as overheating, it could almost anything, thermostat--water pump--radiator--radiator fan-- combustion gases in the coolant--cts. Can you check for applicable trouble codes? Some of the national brand autostores will check codes for free, if there are any.

I starts only with starting fluid and it dies after 3 seconds


Check by the fuel tank


Have someone turn the key on
& listen for fuel pump

Put a pressure gauge on the motor
at fuel rail & check pressure

Pump only runs for 3 sec, if you got no crank signal
or it fails to start

Have to cycle key

The 2003 rendezvous just "chugged" off then would


If it was otherwise running OK up to this point, and just suddenly died, it's probably fuel delivery system related.

Start by checking cranking fuel pump pressure. If no (or very low) reading, consider replacing fuel filter. Then check again for fuel pressure. If readings uncharged from initial check, you may have a failed fuel pump.

Could be a lot of different things, but space doesn't permit listing all.

In my opinion, this is a logical place to start looking.

2002 buick rendezvous turn over but will not start. started then stalled now will not start


DO A SPARK TEST USING A SPARK TESTER AND USE A FUEL PRESSURE TESTER GAUGE TO DO A FUEL PRESSURE TEST.FUEL PRESSURE SHOULD BE 41 TO 47 PSI.IF YOU GETTING NO SPARK.CHECK THE IGNITION MODULE FUSE.IF FUSE IS GOOD.SCAN IT TO CHECK FOR IGNITION MODULE FAULT CODE.PCM FAULT CODE CRANKSHAFT SENSOR + CAMSHAFT SENSOR CODE.IF YOUR FUEL PRESSURE IS 0 CHECK FUEL PUMP AND FUEL INJECTOR FUSES AND RELAY.IF OKAY FUEL PUMP FAULTY.BY USING A SCANNER IT WILL SAVE YOU TIME AND MONEY.NEW FUEL PUMP ABOUT $300.00 AND A NEW IGNITION MODULE ABOUT $200.00.

Car wont start


Check the fuel pump and filter before anything else. You can do this by having someone turn the key to on and listen for the fuel pump to kick on. That's the low buget way but it works just make sure it makes a high pitch sound and shuts off after pressurizing.
