Well... its 21* F outside right now.. car is buried in 5 inches of snow and a wind chill of 2* F... I went to Advance Auto and had them test my HEI units... One was bad.. the other was on/off.. I grabbed a new one.. and hooked it up. After some reading I found out the base of the GM HEI needs to be grounded to a heat sync or metal... I sanded down the heat sync... added some di-electric grease... and hooked it all up. Problem solved.. bad GM HEI unit.. I shorted the other out... Cause? improper grounding of the base of the HEI unit.. YES all connections were correct, but it was all due to a corroded heat sync and improper grounding of the base of the HEI.

Ok .. I tested the HEI... wtf its brand new... I did the following + has "B" and 12v connected - has "C", "W" is ground, "G" is FIDLE I left out the condenser.. this is ok right? I then used a wire and connected it to the "G" terminal of the HEI unit. I then pressed it against the + side of the coil... Nothing.. No spark.. nada So why all of a sudden did this NEW HEI go bad? Now what?

Ok.. I guess the neg and pos reads 12v untill the GM HEI tells the coil to fire... then the negative collapses and turns to ZERO.. another thing.. I used a volt meter and hooked it up to the TACH on the relay board (dizzy input) I have a reading of ZERO volts... on the TACH input.. does this mean I am not getting a dizzy signal?!

OK.. I bypassed that "coil resistor to be safe... no luck... I am checking the voltage on the coil terminals.. I am getting 12v at the POS and 12v at the NEG! whoa..I should not be receiving a 12v source at the negative terminal should I?

Oh in addition... included in this picture.. where the BLUE wire coming from the NEGATIVE terminal of the coil.... does megasquirt still use this "resistor?"

I have a reading of 100 RPM while cranking the engine. So the issue is with the output side of the GM HEI? or with Megasquirt?

Specs - Megasquirt n Spark 2.2pcb 021u code. 83 dizzy, GM HEI and stock igniton coil. Ok.. I was driving down the road.. and all of a sudden the car died. I pulled into a neighboorhood and began some tests.. I have fuel pressure.. the plugs are wet so it is spraying fuel. I pulled the spark plugs.. NO spark. I pulled the spark electrode wire out of the coil.. and since I had no multimeter I cranked it and held onto the electrode, I definatly got one hell of a shock. I assumed it was a cap/rotor. So i replaced the cap and rotor... and no spark! Hmm.. I tested the coil again and there was no spark and no shock Now to source it down... the coil is an original 1978 coil, So i replaced it with a MSD Blaster 2 coil. Car fired right up, drove it home, died in my driveway. No longer ran, and would no start. I am assuming it was the GM HEI setup, so I put in a NEW GM HEI module.. still no start. The problem is, I am not getting any spark out of the coil.. and is not sending any spark to the dizzy. My only other assumption is the DIZZY is bad.. and is not sending a signal to Megasquirt. So I measured the voltage on the GM HEI to see what was going on. (INCLUDED IS A DIAGRAM TO HELP) B (goes to + of the coil) = 12v C (goes to the - of the coil) = 12v W (GM HEI ground) = 0v (obviously its a ground) G (attaches to Megasquirt) >>> [ 1)On initial turn key to ACC, the fuel pump primes, and the voltage is 12v for a few seconds. I am assuming MS is sending an signal to the GM HEI which is why I can sense voltage. 2) In addition I can read 12v while cranking at this terminal. 3) The voltage reads ZERO (0 volts) when the key is on ACC and the ignition is live, untill I crank.] Now.. I have NOT read the voltage from the dizzy to megasquirt since I am getting postive voltage from MS to the GM unit (if the dizzy is bad will this still show a reading?!) The coil reads 12v and is getting power. Could this be a problem with 1) Megasquirt? 2) DIZZY 3)coil wiring ??

check out my putfile link.. I added the cheap home depot lip and rivets.. looks fairly unique

Depot sells PINK foam.. and white foam with blue film over it. Tony D is correct

Have you considered DATALOGGING Phil?! makes life 100000 times easier

Happy Birthday sir! come back to america now!

i thought you were going turbo Dreco? but looks great!

LoL.. nooo Bryan If you want the motor though Bryan its yours my friend.. if you ever decide to buy a Z car again! hows the Pontiac coming along?

Nice ! Welcome! You should come out to the ZCCC (Z car club of colorado meets) I am usually at every track event.

PM sent gijonas awsome work btw =)

I am giving away a FREE F54 block with dished turbo pistons.. I need to get rid of this engine because I can not afford storage due to tuition and school. I needs to go by the 15th..

dont GT cars place vents/louvers on the top of the fenders to release all that high pressure buildup on the top of the wheel well?? I know wheel wells typically are an area of general low pressure due to air movement produced by the wheels/tires.. but as the air reaches the top of the wheel well/fender there is a high pressure build up? I would think this "duct" would increase the high pressure..

run the PVC open.. do not attach a filter or hose.. see ow the car runs.. as for the valve cover breather.. do the same thing temporarily.. use a small screen to prevent objects from goin in... the valve cover breather and PVC breathe OUT .. so nothing will get sucked in.. but just in case then report back to us BTW - does the car smoke immediatly on start up? or does it take a bit? if it smokes on startup and all the time its a bad valve seal

Im rather confused.. engine is now listed for $300 .. come on complete engine for $300!! take it people!

no.. lol

Check your PVC... might be clogged.. too much POSITIVE pressure in the block.. so much the oil is not draining down the oil line into the oil pan.. so its backed up.. has no where to go but OUT.... this will get oil in the compressor and intake piping.. as well as oil in the exhuast which burns and creates smoke notice it only smokes when WARMED UP!? well when its cold.. the oil is dripping into the exhuast but doesnt burn because its cold. then the exhuast heats up then you have smoke how do I know? ive had this issue.. i eventually just ran an OPEN setup with a mesh screen..

um.. for one I work at Home Depot.. and two you need to be 18 years old to work there and you can only start off as a cashier and three only grannies work specialty desk jobs go to your local AUTO parts store to buy this
