Electrical problem
1992 Pontiac Firebird 6 cyl Two Wheel Drive Automatic 80 000 miles

I took my car out after the winter and it started, but it made the same noise of a car running out of gaz. When I start my car the engine cranks, but do not start. I changed the distribution cap and the battery, but, this did not make any difference. I also checkedr if the spark plugs were powered and they all are. Also I cleaned every single connecter and verified all the fuses of the car. Also we try to incorporate some starting aerosol product into the intake, without any result.

You got spark and you use a starting aerosol and didn't start-I recommend you check the fuel pressure to rule out the fuel filter and the fuel pump.

The fuel pump is working properly the only thing that I didn't was the fuel filter maiy be it is block and because of that I didn't enough fuel pressure. Also I try to pour directly some gaz in the engine without any result. I wondering if the problem maybe come from the anti-theif systhem which can be malfonctionning.

Check the fuel pressure with a fuel pressure tester and recheck the spark

I change my fuel filter, but without any positive result also the fuel pressure seems to be normal at the engine. I notify that my fuel have a strange brownish color when I remove the old fuel filter. From this I think that my fuel injectors are dirty so the fuel cannot get to the pistons.

My Sparkplug are covered by something called "Dry Fouling" in the NGK website quote: "
Dry and Wet Fouling
Although there are many different cases, if the insulation resistance between the center electrode and the shell is over 10 ohms, the engine can be started normally. If the insulation resistance drops to 0 ohms, the firing end is fouled by either wet or dry carbon."

For unknown reason I don't have spark any more, I mean by this that now my spark plug are not powered. I try prior this week I test all my spark plug and wire with a test light and everything was working properly for the wire and most of the time for the plug, but now I don't have any power in my wire even if the rotators and the distribution cap are brand new.

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it
