hello, i have a new coil, new ignition module, the car rolls over acts like it is not firing, check the two wires coming out of coil when the key is on, they are both hot but cannot get any spark to my plugs? I would like to add that my ignition switch is pretty tough to turn on and off at certain times. Any ideas of how to fix this problem. thanks

 

ok. Its easier when we know what yr.

Not getting fuel does the same thing. Do you know that its not firing or is that just a guess? Had a spark tester inline yet? do that and get back...also do a noid lite and fuel pressure test.

 

spark to my plugs? a question, or did you verify it, and how?

what year vette, IF it's a vette?

the 91 GM oprs manual supplement says to lube the lock "lightly" with 32w synthetic engine oil. I have put wd40 on the key, then use the key in the lock. not part of this problem, tho'.

 

hello, it is a 1985 corvette, and it has a 383 stroker engine. sorry don't have the equipment to do the test you recomended. but was running, and just quit. thanks

 

what does an ignition condensor do?

 

if your wire closest to the firewall has 12 volts when the key is on and when the engine is turning over, and you are not getting spark, the problem is in the distributer. pull the cap and make sure you didnt forget something.....rotor? module plugs loose? not screwed down tight? spring and button not in the cap?

 

with a points ignition, they added resistance, and a few other things, now their main function is ignition noise suppression for the radio. theres a test for them , but I havent seen a bad one since they went to pointless ignition.

 

have you confirmed that the distributor shaft is turning? you may have broken somethng if it "just quit."

 

Improvise...

after dark, stick a nail or whatever metal you have in a spark plug wire cap and get it within 1/4" of the intake or something to ground and crank for 3-4 seconds...you should see a bright blue arc at least 1 time every 2 secs...if not, wait for sunrise and enter the dist. Problem is in there. Look for rotor turning, and again, pinched wires. Also, remove the cover and check the 3 wires in top that go to the 3 clip and the 2 clip below. HEI fire under water...
They're hot and fire up to 40,000 V at lower speeds. So its either broken or shorted.

Fuel. Key On with silence...do you hear the pump run for 2 seconds? yes? go to the shrader valve and press in to see if there is substancial pressure. It will spray with 3 psi...you are looking for a bath... if no, go to the pump relay then the filter. It should run the pump without a relay but it takes more cranking time to build oil pressure to trip a backup switch.

Go to each inj plug and wiggle it and press onto the inj. make sure all inj wires are not laying on anything or twisted around each other. A single short can kill the whole mess.

85...after spark is confirmed, its almost a sure thing for filter or pump.
BTW as mentioned condensors are not critical parts of the HEI. They serve as a filter mostly. Not to be confused with a capacitor which is a part of an HEI system. Thats used to discharge high voltage rapidly.

 

beat way to test for spark. Take plug wire off plug have wife stick pinky into boot where plug would go. Crank car over if she jumps 10 feet and calls you every name in the book you have spark. LOL If not keep looking

 

lose more wives this way

 

best laugh I had all day, Good One
