No spark at plugs. Doesnt start. '97 Tahoe

[eaj343]

I am unable to start the vehicle. It cranks fine, but doesnt start. I have changed the fuel pump, distributor, cam sensor, plug wires, and plugs, but still it will not start. It has spark at the coils, but nothing at the plugs. Any ideas?

Only one coil. Check your coil wire, cap and rotor..... Suspect coil wire if coil has fire and none of the plugs do. Have you tried a shot of carb cleaner into the intake before cranking?

Disregard, didn't see that you had already replaced the distributor.

The coil wire looked good. I cleaned the throttle body, it was pretty dirty, but the problem still persists.

Look good and is good is 2 different things. Does it have spark thru the coil wire?

^x2 Either ohm the wire out, or put it thru the spark test.....

It does have spark through the coil wire. The parts I have already changed, were done about a year ago. Is it possible that one of those parts has gone bad again?

Spark good thru coil wire, but bad out of cap, try a new cap and rotor (OEM ones only...)
