in the engine compartment. It will have two water hoses and a cable hooked to it.

Does the fuel pump have a fuse?Carefully pour a little gas in throttle body to see it problem could be clogged injectors. Engine will run rough but keep going.Harder- check fuel pressure to see if the regulator is too low.Normal is 40-45 psi. Check injectors with ohm meter should read 13 ohms. This test involves removing the plenum and unplugging the wires.I do this one at a time to prevent switching the wires to wrong injector.

Hi there:You will have to pinpoint what the engine is missing... Spark / Fuel / CompressionAll three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the engine to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should.Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using FixYa, have a nice day.

anti theft deturent light flashing??with key on engine off??

it is very easy. you need a 14 and 15 mm socket with a 6 inch extension with a 38 racket

sounds like you have no output from your alternator which means the car will only run while the battery has enough charge to produce an ignition spark .

Hi Colton, Check the fuses and operation of the relays, It is unlikely that both motors have failed at the same time. You can check the motor operation by simply taking a cable from the positive battery tower and connecting it to the positive side of each fan in turn. If they run they're fine and the fault is elsewhere. If all relays and fuses check out fine, the problem will be with the temperature sensor. Regards John

Did you check for a blowin fuse,Or the fan relay could be shot, Or on that old of a vehicle the cooling fans could be shot. The way to test fan is unplug them at the plastic module End use a jumper wire going to your battery , If they don,t come on then you no the fan is shot.

Possibly a fuel regulator or injectors? it seems that there is insufficient fuel going into the combustion chamber. Take the fuel line off at the fuel rail and stick your finger over the hose, now get a friend to initiate the fuel pump by turning the key to on for a split second, if you cant stop fuel from ******* out from where you have your finger you know that the pressure is ok up to the fuel rail, put the fuel line back on then move onto your pressure regulator etc.

could be converter on exhaust is plugged up and will cause these problems..

may want to have it checked out ,,,could be tappit,,valves and so on....could be so many things

take it to the shop.it could be a many things........

As with any no start issue, you will need to figure out if you are dealing with a no spark or no fuel problem, or both.You need to know if the plugs are getting spark and the injectors are getting fuel pressure and pulse from the computer.

We have recently uploaded pages with a description andphotos of how to replace the lock cylinder on GM vehicles (for a small fee). They are broken down into step by stepdetailed instructions. Here is a link to that page. This covers most of the locks from 1995 topresent.http://www.steeringcolumnservices.com/steering-column-repair-how-to-instructions/gm-buick-cadillac-chevrolet-oldsmobile-pontiac/lcg06-ignition-in-column-lock-cylinder-removal.phpLastly, I would have a new lock cylinder in hand before youbegin, to see what you are working on (hidden in the column) and accomplishfinishing this job quickly.Good luckDoughttp://www.steeringcolumnservices.com
