Hey all-

My damn Z wont start. I have replaced the ignition coil, the cap, the rotor, and now the ignition module. What else is left? It's getting all kinds of gas, all kinds of spark, and it doesnt start. Just wanted to see what you guys thought about it. Thanks

timing right? could be far enough off so it wont start.

Is it actually cranking, or just doing nothing? Just wanting to clarify....

Baer Brakes 12" Sport System

It is actually cranking. Spark, gas, and everything. No start though.

What do the spark plugs look like?

Most likely the spark plugs are wet. replace them with new ones see if that works. Cause it sounds like you flooded it

I dont think its flooded, cause the plugs arent really wet or anything. its been sitting for a couple days, so i dont think there would be a problem with flooding.

On my 86 IROC (carbed) the needle and seat was sticking on the Q-jet and causing the carb to dump in way too much fuel...thus fouling out the plugs ASAP and the excess was burning thru the cat and glowing red..

I got a rebuilt Q-jet and it runs like a champ

If you're SURE you have fuel and you're SURE you have spark, it can only be timing. Check your distrib, might be loose. It's happened to me before

Also, check your plugs. If they're soaking wet you're flooding. If they're really oily you'll have a hard time starting as well.

Do you get a cough or any attempt to start?

Is this a carb car or TPI?

Or check for a wire disconnected on the coil, or just look around fro diconnected wires, one of the wires of my coil came loose and it woldnt start

I checked the timing and its right on. It doesnt really seem like the plugs are too oily, or like the engine is flooding. It is a carb engine. Still trying to figure out whats going on. Thanks

pull the coil out of th top of the cap and check for a crack... or a bad ground or something... is there anything that led up to this???

zroc

Nothing led up to this, just one day it didnt want to start. The coil is new and i know all the grounds are made.

timing chain? look in the oil filler while having someone crank it. valves moving?

I'm tellin ya - carb !

Check the archives for my posts about 3-4 months ago about my LG4 86 IROC...

I tried EVERYTHING, like you have - it was carb...didn't make logical sense, but that's was it..

Look into it...
