You can have someone turn the key on and listen at the tank for the pump to run for 3 seconds.
Or you can jumper the fuel pump relay to make the pump run manually.
Have you tried starting fluid in the throttle body ?

Check for a bad distributor cap and or rotor..........a bad cap and or rotor can caues firing (cross fire)across the terminals and introduce spark to the wrong cylinders at the wrong time.......
hope this helps.....good luck!

if this is the vortec engine you may want to check to confirm that the injector pot is working. The injector pot is located under the air intake manifold (top half only) & PLEASE BE SURE TO DISCONECT BATTERY FIRST. if you unbolt the top half of the intake manifold you will find the main injector pot otherwise known as the SPIDER. This part does have a history of failing and can be very costly to replace if you purchase it new. most junk yards should be able to find one for you.

Is the security light on? If you have spark and fuel, it should run. Any codes? Could be bad crank sensor or cam sensor.

If your air mass meter tests good, the I would tell you to check the HIGH PRESSURE PUMP underneath the Driver's side chassis pump holder-next to the fuel filter.

There are 2 pumps on your Volvo---the in-tank low pressure, and the chassis mounted high pressure. The car will run with the in-tank failed and the high pressure good. It will not run with the high pressure failed. Test the pump by applying voltage to the two terminals.

Another common failure, should the high pressure pump be good, is the HALL EFFECT SENSOR located in the distributor on the back of the engine. Once this sensor goes, it's no start. A rebuilt or used distributor may be the answer to your problem.

My pontiac grand am 2003 will crank but wont start


Timing belt broke? Do you have spark at plugs?

I have a 95 grand Cherokee. I'm getting fuel, and I'm getting spark. I replaced the crankshaft position sensor, and it still wont start. I spray starting fluid in carb, it starts and dies. Please help


what does getting mean? which engine, 4Liter or 5.2 or what?
spark at all cylinders is getting and timed right?
runs on test fuel so sparks good, that means fuel is bad
or flooding or too little fuel.
code 12 cranking for 5 seconds, means sensors are ok.
why replace parts that make spark when sparks good, it run on test fuel, why worry spark.? and not just fueling.?

now lets do fuel, step one is fuel pressure, not squirt tests.or dribble test. a real tool called,a fuel pressure gauge that works, and nothing else, (unless rail is dry and now we know its not)

if all spark plug tips are dry, are they?
then its not injecting, (the ECU can cut injection for 2 reasons) ask
or there is no real pressure.
so we open the FSM and read page FUELING
49psi is idle pressure, (more cranking with so little vacuum)

the tests are all there,

I have a 2004 geand am. the motor turns over but wont start. I changed the fuel pump, the ignition is good, fuses are all good but it will not start


Check for spark (pull a spark plug and arc it to a grounded surface) and check for fuel to the engine (can be done through the spark plug hole opened by removing the spark plug)

2004 grand am stuttered then stopped working all together, wont start at all


Fuel pump? When you turn key to ON, do you hear the pump come on for 2 seconds to pressurize the lines? If not, you will need to have the fuel pump circuit checked for a failed fuel pump.

If the pump is working, start looking into the ignition system by checking for spark on one of the spark plug wires. If no spark, possibly the ignition control module or the crank position sensor.

1997 pontiac grand am 4 cyl. had spark plugs changed in feb. has had trouble starting in past, now it wont start. it turns over and fuel is getting to it but just wont start...plz help


The ignition control module needs to be replaced. It is located on the cover you remove to replace the spark plugs. You can have it tested before you buy a new one to be sure it's bad.

Engine wont start no spark......ignition control


I had a car a couple of years back do this to me, it was the crankshaft sensor. It will not fire at all if it is bad. Luckily the part is really cheap.

"why isn't gas getting to my spark plugs in my 1998 Pontiac grand am"


Either the fuel pump is shot, fuel pump relay is bad, or fuel filter needs to be changed. A fuel pressure test would be a good place to start. Also changing the fuel filter is cheap and good routine maintenance anyway.
