Starting Issues....Please help

[95CobraMike]

Well. after my HG install drove the car around for a while, and to columbus and back...after sitting most of the winter. i'd say it was driven about 350 miles since the HG install. then it sat again for about 2 weeks. got it out the other day, drove it uptown washed it got gas, brought it home to take pictures and then i parked it for about 5 min in the drive way.. well then my sister wanted to play bball so i had to move it. it cranked jut fine but no start. after a few tries i could smell gas pretty strong.
i took it apart today and tried some diffrent things...
i have MSD ignition which has been on the car since i bought it 3,000 miles ago.
-what kind of voltage should be on the wires that come from the msd box to the coil??
-i did the trick to see if there was spark at the coil by seeing if i had spark from the coil to the block, but i didnt have anything.... is it the coil??

my guess is the coil or the msd box...

when you washed it did you get the msd wet I cooked two boxes like that 4 years ago and they didn't die right after I guess it took a while to cook the circuits

 

[95CobraMike]

i dont think i got it wet....it was just like any other normal wash

how would i check to see if it is fried?

 

[cavscout371]

If you have any good performance parts stores around they'll have a box tester but in short if there's voltage going in and none coming out you know its it

 

[95CobraMike]

there are two wires going to the coil from the msd box....from ground they both have 12 volts on them
is it suppose to be that way?????

 

[cavscout371]

if you have an volt/ohms meter you could test the coil for resitance that doesn't sound right 12n12

 

[95CobraMike]

how do i test the coil??? black contacter to output or red contacter to output?

 

[cavscout371]

also check the big red and little red wire on the box for 12 while ingtion is on also try while cranking see if it drops

 

[cavscout371]

how do i test the coil??? black contacter to output or red contacter to output?

i'll send you some pics in a min

 

[95CobraMike]

i just checked the resistance on the coil....
first from red to output then from black to output and got nothing either way...
then i went from red to black and got a reading anywhere between 0 and 1 ohms...
this means there is a short in the coil right??

 

[cavscout371]

for primary windings 0.5 to 2.0 ohms

for secondary windings 8000 to 20,000

haynes manual should narrow down those resistance numbers a little

 

[95CobraMike]

oh when i went from red to black, the msd wasnt attached...that reading was directly from the coil

 

[cavscout371]

you dont want the msd attached when you do this your just testing the coil itself

 

[95CobraMike]

MSD is the problem....
i removed it and hooked the ign up like it was from the factory and it fired right up...
but it backfires now every 5 seconds or so... need a new msd

 

[cavscout371]

that sucks if you try to warranty it don't mention that you washed your car they'll make you a buy a new one I got both mine warrantied cause I didn't mention a thing about getting it wet

 

[95CobraMike]

are they all warrenteed? or did the buyer have to send in a card for it?
if so how long is the warrentee good for?

 

[cavscout371]

I bought mine locally at a performance shop and they took care of me its usually a two week turn around if they have to send it to msd but in portland, or where i used to live the performance store hooked me up if I was racing that weekend and gave me a new one off the shelf.

I don't know where you got yours from but you might have to contact msd

 

[95CobraMike]

im not sure where the guy got the msd that had the car before me.... if i call them (msd) with a serial number, they should know right?
