Welcome to ZDriver!

Start by checking the fusible links. If you haven't done so yet, download the FSM for free at XenonS130 - S130 Reference

My thoughts are... it's good.

Did you fix the problem?

if you can't get an s130 running I think megasquirt might be a stretch.

not yet...thanks for the link..I'm on my way!!..this car was running when the previous took it to a shop...3 mos later..the car was towed home...the coil wires from the igniter was connected backwards,and the ecu was on the floor with several wires spliced..I changed cas,igniter,coil...nothing..so far...I'm checking for continuity from dizzy to ecu..then I read a post that said I should have a green light in ecu?..so now I'm checking ecu part #..and what causes a green light.

No..not yet..this is new ground for me...I changed cas, Ignitor,and coil,I checked for conuity in wires that connect to cas from harness.(checks out good).now i plan to check from harness to ecu...still no spark,injector pulse,fuel pump or green light in ecu..if its the ecu I was thinking mega squirt instead of the stock ecu.

no green light no power to ecu. (highly unlikely the led burned out)

Start the car and rev it to 2000 RPM for 3-4 minutes then you will see the green light blinking!!!If you see it blinking then your ECU is working....this is the only way to see the green light.
If your car not starting then you will never see your green light.Time to trouble shoot and test!!

Thanks Nismopick for the service manual link,...if it turns out to be the ecu...I'm leaning towards mega squirt...the fusible links are fine..how do I check the cas?
