Pontiac: Update to Pontiac not starting

Update to Pontiac not starting
Just an update: No spark to any spark plug using ignition tester. Could Magnavox coil(3 pack coil on one housing)go out all at the same time?? I will test fuel pressure next. Supposed to be around 41-47 psi. I have not checked the fuel filter yet.

Re: Update to Pontiac not starting
hold it right thar pard, the ignition system is separate from the fuel
system. dont worry about the fuel, get spark 1st, yes you test the
spark from the coil wire, (de big fat wire in de midle ob de coil) hold
it about 1 inch from a ground, (any nut or bolt) and have a buddy crank
the engine, it should throw a white or blue pulsating spark for about 3
inches. if it dont here is the trick....go to a junk yard and pull the
entire distributor from another car with a distributor like yours might
find one in a chevy or a buick, then just swap 'em out be carefull not
to rotate the motor while the distributor is out. then just plop the
new one in with the rotor in the same position as the old one with out
changing the timing, dig....?

More likely that the ignition module is not telling the coils to fire or that the CKP sensor is not sending a signal.

Re: Update to Pontiac not starting
Another update. On the crankcase postion sensor I have voltage at three of the four terminals with the ignition on. Also the coil's primary side tests OK but I get readings from 11,000 to 15000 ohms on the secondary side(should be 5000-9000 ohms). Is this OK because it's the original coil (15 yrs. old) or is the coil bad?? Thanks, Gary H.

Re: Update to Pontiac not starting
Replaced coil. Still doesn't start. Fuel pump ok. Easiest way to check ckp and camshaft position sensors??? Any way to check ECM/PCM(computer)?

It should run if it doesnt see the cam sensor... A oscilloscope is the
most accurate way to check both of those sensors. The easiest thing to
do is to check for spark. If it doesnt see a signal from the crank it
wont know when to fire. Use noid lights or a voltmeter on the injector
harness to see if the injectors are getting voltage from the ECM, it
will come in as pulses.

Re: Update to Pontiac not starting
Don't know what a "noid" light is. Also. I don't have any spark to any of the spark plugs when I turn it over. How do I hook up the oscilloscope? Do I need a special adapter or something? I checked the crankshaft sensor with the key on and I had voltage at three of the four terminals. Do I check voltage at the injector terminals? Thanks for any help. It's my boys car and I'd really like to get it running. Gary H. Vancouver, Wa.

How was the cars behavior before it gave up? Did it act up any or just
die?
Ok a search in google.com will tell you what noid lights are but since
there is no spark you can skip checking your injectors. You said you
replaced the coil pack, did you replace the ignition module as well? Can
you see your crank sensor? Reach down and gently try nudging it to see
if its loose.
There are 4 wires on your ckp. (looking at a 98 manual online)
1. Sync Signal - light blue/white
2. 18x Signal - Yellow
3. Positive Voltage - White/Black
4. Ground - Black/White
