There should be a Schrader valve on the fuel system under the hood to check fuel pressure. Remove the cap and depress the valve while someone turns on the ignition switch. If no gas comes out, the fuel pump is not working.
If there is fuel, remove the coil wire and hold it close to something grounded on the engine while someone cranks the engine over. There should be a spark jump from the wire to the engine. If no spark, you have found your problem.
No fire from the coil could be caused by a bad coil or no electricity coming to the coil. To check for electricity at the coil, unplug the leads from the coil and using a voltmeter check for 12 volts on one of the wires.
If you have fire from the coil wire, pull a spark plug wire, and put a spark plug on it and ground it to the engine. While cranking, fire should jump the gap on the spark plug. If no fire is found there, the problem is with the distributor cap or rotor. Pull the cap and clean the contacts, and check the rotor for cracks and corrosion, and replace as necessary.
If none of this works, get a mechanic that knows what he is doing.

So far we know what kid of vehicle it is and that's about all!
Does the starter crank the engine? Do you have ignition working? Find out if engine good otherwise by spraying a small amount of ether into the intake manifold/carburetor- with air cleaner off (then put back on before cranking.) If you get a burst of engine running - even just a few hits, - it is fuel. If nothing happens, - except engine turns over, then check over ignition system. 91 model may be old enough that it still has distributor, if so pull out middle wire and hold it near engine metal part somewhere( using insulated item to avoid shock) - Then have somebody crank engine and see if sparks jump to "ground". If solid state "direct ignition" pull a wire off one of sparkplugs & check for spark (note that it will spark only once every other- time engine turns over, so make sure it spins over a few times) also a sparkplug laid on a metal part is nice because newer "hi-tension" electric ignition puts out about 60,000 volts and it jumps a long ways! After these checks, at least you will know what area to look for problems in!

What kind of noise is it making?
If it turns over, it is not your starter.
If it clicks, but doesn't turn over, it's your starter solenoid.
Turn your key in the ignition, (don't crank) and listen for a humming or buzzing noise near your fuel pump. That is the fuel pump priming the system. if you don't hear that, check your fuel pump relay.
If you replaced you battery and alt., then I assume the engine is not turning over. What about your ignition switch?
Sometimes, if you were cranking your steering wheel as you parked, it will not be "locked" and you will not be able to start the vehicle. Pull on your steering wheel as you try to turn it over.
Another common, simple solution, is be certain you have the vehicle in "park."
Have you changed your fuel filter? That usually causes fuel pump failure.

is the engine cranking/turning over but not starting? if so, look at the tachometer and see if it is pulsing. If not then you need a crank sensor. If it is pulsing, check for fuel pressure. Small valve under the hood looks like a tire nozzel it should have a cap on it. Push the center pin down fuel should squirt from there after cranking the engine. No fuel, then fuel problem. Fuel means ignition problem. Ex. module problem. cap rotor problem or distributor problem. Hope this helps you out. Ron

Check the fuel pump circuit breaker. It is under the glove compartment behind the carpeting and mounted on the firewall. This little breaker is designed to trip any time the vehicle is struck from the front or rear but also has a tendancy to trip when the door is slammed. It used to happen to me all the time.

you need to check the Fuse first off for the fuel pump,,and ,make sure you can hear it run when the key is turned on,,if you cant check the fuse,,and also the pump relay,,and the safety switch,,located in the rear trunk area,,if all these check good,,and it is getting good fire to the spark plugs it has to run,,be sure and check all this stuff,,before you rule any one thing out on it,,good luck,,i hope this help,s.

Check the ignition coil. Make sure its getting spark from there to the spark plugs. If not could be the ignition module. Hope this was a bit helpful. Good luck.

it might not be firing or you need to see if it is firing take a plug wire off see if it is sparking if it is not that's the the trouble could be bad coil also spray some either in it if it hits the trouble is fuel check all the fuses to make sure there is none of them blown. good luck

Test solenoid. If it's bad replace it, too. If that doesn't do it then a new ignition switch may do it.
When you replaced the fuel pump did you also replace the fuel filterS???
