 thanks adam

the coil from the 93 grounds through its mounts so if you mounted it to the fender without grinding off the paint it could be your problem, just an idea.  good luck

[Cheesemaker]

Are you getting power to the coil?  Is the pick up in the dist. sending signal?

[gnob]

the computer controls ground.
is the manifold ground hooked up?
do you know if the ECU is actually turning on?
do you have a CEL wired in?

[okemosdrig [OP]]

everything grounded ecu has power and it goes througt when i jump starter relay    i will check for distributor pickup power

not sure what the cel is    coil and igniter have pwer

[pumkin toy]

cel is Check Engine Light

[okemosdrig [OP]]

yes i do have a cel. but dnt think i checked it for power will check it out.  cleaned coil mount grounds no help.  no juice from distributer pickup either

[jimbo74]

ok, so it doesnt work @ all, any interior power?

or it just doesnt have spark?

if it isnt spark, could be a few things..... timing, coil, igniter, distributor, or a too dead battery.....

however, if you are jumping the starter, why isnt the key not starting the vehicle?

Sounds like you have a issue with the coil and ignitor.  Maybe the wire between the dist and coil.  Just cause you got power to the coil/ignitor, doesn't mean they are working.  Find somebody that has a working coil and ignitor and try those.  Check to see what the resistance is in the wiring. 

When I bought my truck it wouldn't start, but would try.  Come to find out there was a bad wire that ran over the exhaust manifold that had fried the wires.  I didn't know about this until I checked for resistance in the wire harness.  I followed the holy bible (FSM)    On what each and every wire should be getting for resistance and ohms.  Without that, I would have had to buy a harness.

when i turn key over  it does not turn the starer but starter ecu coil igniter get power.i have ohmed coil and igniter they are good  have interior pwer  battery good    iam just going to pull harness and retrace all wires this weekend   i think it is something with ignition wires   did not tie them into 82s ignition yet just used donor ignition to try to start.

Did you get the relay that is mounted above the ecm that is for the starter. 

[okemosdrig [OP]]

probably did not get the starter relay found out all three of mf books on toys dont match the 93 wiring diagram  they say typical digrams but when i really got into it they do not    waiting on fsm for 93 wiring thanks for all the help
