So I just bought a 93 SI. Ran like a top, only problem was oil leaking from valve cover gasket. I replaced it and cleaned off the motor using a auto zone brand engine cleaner. Got the motor spotless and the oil leak had stopped. I even started it when I was done to ensure I hadn't shorted anything.
Well on the way to work the next day the car just shut off going down the road. Like I turned the key. I have since replaced the main relay, cap, rotor, plugs, wires, and fuel filter with no luck.
Anyone have any idea what I could have done? It seems like I'm getting fuel, because if I loosen the banjo bolt on filter it sprays fuel out. But if I put a screwdriver in a plug wire and try to see spark I get nothing. Someone help me out please.

Did you check whether your timing belt is still intact? High mileage t-belts can snap under even low load conditions (less than 3k rpms).


If the belt is okay...
You can purchase a real spark tester for ~$5 at an autoparts store to check for spark.
Then check compression.

If the car doesn't start there has to be a problem with one of these...
battery -> starter -> fuel -> spark -> compression

if you're not getting spark, and you've replaced what you say you have, I'd look to see and make sure all your sensors are plugged in properly, and their wires are intact.

I'm a fairly decent mechanic, but I lack the specialized tools to do a real in depth investigation.
The car ran perfect the day before, has never blown any smoke or burned oil, which would make me think the compression was ok. The battery/starter is fine the motor cranks with no problem. As far as the timming belt is concerned, I thought these were interference motors, and if the belt broke you would get piston to valve contact?
Like I said before I can turn the motor over all day long and not hear anything funny that would lead me to believe there was a broken belt.
I'm about to do a search, but what about the coil or igniter?

It was the igniter, Thanks for the help guys.
