so i have a 1985 z28 with a 5.0 and qjet. i was replacing the plug wires, cap, rotor, and coil and now the car wont start. not getting spark at the plugs. dont know what i could have done wrong, its a simple task that i have done many times. im completly boggled. any ideas as to what might have gone wrong? and why i can crank the motor over but it wont start? help is appreciated. thanks to all.

 

ok take ur air filter off and then check coil wire did
u put it back on? its possible u put the cap on wrong and the rotor hit the cap and broke the rotor has happened to me before. check the wires coming out of the distibuter if u have old style two plugs check if wires were pulled from plug housing write back if u dont figure it out? stevo
----------
if one of those wires are off one of them gives ur dist power when u turn key on

 

it has the hei ignition, so the coil is over the distributor cap. and i inspected the cap, nothing is broken, and everything looks perfect in there. the plugs that plug into the cap/coil are in good condition. plugged in, everything looks like it should be working properly, i cant figure out what happened. could the spark plugs be shot? i would think the engine would make some attempt at starting though. any clues? i need to get this thing back on the road. will be checking back periodically and reporting my findings. thanks.

 

make sure your plug wires didn't get out of the firing order

 

Are you getting spark at the plugs? Be careful and use a spark tester (only a few bucks) the HEI puts out a lot of voltage.

also, you didnt accidentally unplug the pickup coil from the module did you? (Not that I see why you would have)

 

okay well did u check the rotor button? it could be broke ? that or the main terminal that touches the coil tab in side the distributer in the center wich sends fire to each plug/the fire runs through the rotor button.it doesnt matter if its out of order it would still have fire.take an extra plug u have laying around take one of ur plug wires off and put the extra plug in lay it on the block and turn it over (best if done with 2 people or in dark) thats how u see if u have fire.yea if u dont have fire take the rotor button off and see if it is good.

and if that dont work try ur old coil

did u gap ur plugs?and when u turn ur key on is the fuel pump comin on?
