Hi, the only thing common between the fuel pump circuit and the ignition circuit is the ECM itself. Recommend you check the ECM fuse. Not sure if it's in the car or the engine compartment fuse box. If this isn't the problem, you may have 2 separate problems. Your car doesn't have passlock anti-theft does it?

Welcome to Fixya

Here are couple of steps you need to check to your car. Do a test for spark at the plugs. Remove one of the plug wires from a plug and hold it near grounded metal. (If the plug end has a long insulated shroud, you may have to improvise to get ground close enough to the end of the wire.) Have someone crank the engine while you watch for spark. If you get an 1/8" or so of spark, that should be enough to fire. Check the distributor cap inside for signs of cracks or carbon arc tracks.
Also, check to see that the little carbon contact for the center terminal is in place; without that you can have spark but it won't get to any plug wires. Test your coils by using a voltmeter. Connect the tester (meter or bulb) from ground (engine case) to Terminal #15 on the coil. Never mind what the actual markings on the coil say; connect to the terminal which has the thick Black wire from the main harness on it. I say never mind the markings on the coil because someone may have swapped wires around which could lead you astray. The tester should show 12 volts (or 6v). If it doesn't, there is no power from the Ignition Switch.

Thank you for using Fixya!

My 2000 Pontiac grand prix stop running the other day. It turns over just fine but it won't fire up could it be anything other than the fuel pump. ( I really don't want to change that)


its pretty simple to check for fuel pressure. If there is no fuel pressure than the next step is to check for power and ground at the pump. if those check out then a new fuel pump should fix the problem.

your engine needs 3 things to run. fuel, spark, and compression. if you have fuel pressure than check for spark. if there is no spark than there could an issue with a crank or cam sensor. If the crank sensor is bad than typically there will be no injector pulse as well. after cranking it over a couple times pull a plug and see if it is wet. if it is you know the crank sensor is working and the fuel pump is working and you have a spark issue. If it is dry than there is a fuel delivery issue (fuel pump/injector/injector pulse/etc.)

there are many things you can check very easily to help narrow down the possibilities.

Not CAM or Crank angle sensor.. Try check supply fuel line pressure n spark plug n ignition coil output.. the ignition coil output should be blue spark n spark jump at least half inch.. But be careful coz its hi tension..

HELLLP!!! PLEASE!


try checking the fuel pump. most fuel pumps have a filter on them in the tank if they get dirty or plugged it could cause the car to act up.

I already replaced the crankshaft sensor. When the car gets hot it won't crank and then when it cools down it will start back up 2000 Grand Prix 3.8


Could be ignition control module or fuel pump, if you don't have spark to spark plug's, control module, also check for fuel pressure at fuel pump pressure port, port will be on fuel rail.

91 LEGACY STARTED RUNNING ROUGH


The cylinders are numbered as on the spark pack you changed. You might have done better putting the seafoam in the tank as an injector cleaner. Not sure why you changed so many parts, you seem to know how to get the codes from test connector lead hookup and the blink pattern. You might also want to check the fuel rail pressure and the crank and cam angle sensors. Before replacing the injector, swap the #4 injector with the adjacent one and see it the code moves with the injector or stays put. If the code stays on #4, then check the injector wiring, if it moves clean or replace the injector.
