First If you haven't had a tune up for a while try that and change the fuel filter.Then if your still having problems check you pressure at the fuel rail for the correct fuel pressure.This is done by hooking up a fuel pressure gauge to the shreader valve that's on the fuel rail.This will tell you if you have a bad pump or pressure regulator by the fluctuation in pressures.If you have access to a Chilton's manual it will give you the pump pressure required.

It's when the security light starts flashing that the infamous "chip" in the key becomes a nightmare to many. Gradually the car begins not cranking anymore or if it cranks it would start and die in a second. Randomly it will do this more and more often until it won't start anymore. VATS, PASSkey and Passlock immobilizer systems are killing cars all over North America, they have a short lifespan and are certainly more effective against owners than thieves. Here is how you save your car
1st trick, Try a spare key that is newer or used less. The pins wear down and so do the keys causing security fail. 2nd trick, (if not starting) turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start. I did this in my regal for more than a year. If its shutting down while running, im sorry i have no quick fix... If anything on this page helps you, please remember to comment or give me a thumbs up on the myfixya sight so i can have a better rating to help more people on this. Thanks

Cheap fix: Bypass the chip in your key. Temporary, but effective. Until the TDM (theft deterrent module) in the dash poops out, then you're kinda screwed. I was told that these types of key security systems have a 7-10 year life span. Sucks for us. This link explains the "Key Issue" pretty well.

Never worry again fix: Bypass the whole VATS/Passlock/passkey I or passkey II system entirely. Literally take it out, and throw it away. I just did this in my Regal. Took about an hour. Took longer to find the thing than it did to fix the problem. They sell a unit for 200 bucks to totally bypass this system FOREVER. life time-money back and all that. Finally did this in my car. Well worth the 200 if you've looked into getting this replaced... Anywhere from 600-1000 bucks. If you do buy this, please purchase it thru this link. The cost is the same, but i get credit for the sale and im trying to earn my money back, as you will be able to do if you buy fron NewRockies and join the free affiliate program. Thanks
----- http://newrockies.ca?ap_id=judd0081 ----- With this fix, you can take that whole Vats, passlock, passkey system out of your car all together. Good info on both sites.

It works for:
Any GM or Isuzu Vehicle with VATS or PASSKey or PASSLock security systems.
If your car has the chip in the key or in the lock cylinder, then you can save it with this Full Bypass.

the wiring harness is probably faulty. Get a light tester to see if power is going to the harness, and if the harness is receiving it by testing current flow on the connectors. it might just be that the harness is not receivng power and has to be replaced ( new harness is around $40, just dont buy it from a dealer)

You need to retrieve the code to begin. with the code we may be able to help better but The light could also be on beacause a wheel sensor failed. usually if the ABS light and the brake light and the speedometer will not work when the module fails. We usually dont have issues with the pump. If just the abs light is on your best bet is to put it on a diagnostic scanner. That way you can see all the wheel speeds. If a sensor is bad the speed for that sensor will be erratic,

Check the switch that controls the wipers, if the switch is good then you need to check the motor and see if it is only willing to run on high speed and nothing else. You may have to replace the wiper motor

Have you checked wheel balance or maybe a bent drive shaft???

2001 Chevrolet... | Answered on Dec 09, 2010 | 169 views


Are you talking about the ring and pinion gears being damaged? Ring and Pinion gears are a matched set, you can't run mismatched gears together without some serious issues.

You should always have differential work done by someone qualified to repair them. Having a rear end seize at highway speeds can cause a fatal crash.

Hopefully you didn't destroy the differential, have a qualified tech look it over and you'll end up replacing the ring and pinion gears - and the bearings wouldn't be a bad idea at this point.

Read all of these instructions before starting this job.
First test your heater core for flow by disconnecting both heater core hoses from motor and forcing air from an air compressor into one of them watching for flow from the other. If you have no flow then you may need to backflush your heater core - it is possible you have blockage in it. Your local auto parts store has a backflush kit you can buy that will have a backflush valve ( to be added to your supply heater core hose ) and an additive to put in your coolant system. The kit will not include new coolant so you will need to get that too. Install valve and connect a garden hose.Run motor specified time in the kit. Remove lower hose from your radiator and turn on the water from the hose full blast. Watch the coolant coming out from your radiator to see if any chunky stuff comes out - also watch for the color of the flow. Run water until it comes out clear, then shut off water and disconnect garden hose. Allow system to drain, reconnect radiator hose and cap flush valve. Refill coolant system, turn heat on high and run motor until it is warm. Top off coolant in radiator ( be careful - the pressure may cause coolant to spray out when you remove cap - put a rag over the cap before you remove slowly). If you do not have warm air at this point you may have a bubble in the heater core and may need to block rear wheels then raise the front of the vehicle until the radiator cap is higher than the heater core. Restart vehicle and turn heater on high . Check coolant level in radiator and top off, then cap radiator and shut off motor. Lower vehicle and start again with heater on high. If you still have no heat then your heater core may be plugged. To check, remove both heater hoses from motor and force air from an air compressor into one of the hoses, watching for flow from the other hose - if no flow then core is plugged and needs to be replaced, but if you have flow then you still have an air bubble in the system and need to purge using the above steps until you have heat.
Hope this helps and please rate my solution - good luck!!

Hello: The fuel pump relay is in the under hood fuse box, The location should be printed on the underside of the fuse box cover. The box should be on the drivers side under the hood. One other thing it could be is burnt/heated terminals on the connector from the truck wiring to the fuel pump harness. Also check the fuse for the fuel pump (20amp) in the same fuse box.

It's possible a bad alternator is affecting the system. If the battery is run down, many systems may get confused by low voltage input. First check the alternator by measuring voltage at the battery with the engine running. The voltage should be at least 14 volts. If not or you don't have a voltmeter, take the alternator off and have it tested at your local parts chain. If you need instructions for removing the alternator, please let me know. Also, if any problems remain after fixing the alternator, please let me know what they are for additional assistance.
