NO START, NO SPARK Sign In
92 Subaru Loyale
4 cyL 1.8 Liter engine
144,764 mi

Problem: No START, NO SPARK

How is everyone doing today?
I'm working on a 92 Subaru Loyale 1.8 Liter
no spark, no start. There is power coming from the ignition switch to coil.
The primary coil Resistance is 1.1 Ohms, and the secondary coil resistance is 10.19 kilo ohms, so the
coil is good. There is a condenser below the coil. I removed it and put another condenser from the same type of car
still no start, no spark. I exchanged the crank angle sensor distributor and still no start, no spark. The fuel pressure gauge says 20 psi, so the
fuel pump is good.The timing belt is not missing any teeth, or damaged.The only thing left to do is to go to a Junk yard and pick up an ECU and try
that. Any advice would be appreciated before spending money on ECU.

You're writing off a lot of things that you shouldn't be


fuel pressure spec
Maximum 36 - 50 psi (245 - 343 kPa)
Controlled at idle 20 - 24 psi (137 - 167 kPa)

Just because a timing belt isn't missing any teeth doesn't mean the car is in time.

Just because the resistance is good, doesn't mean a coil is good

You need to find out if you have injector pulse and if not, power supply to the injector.

You also need to scan the computer for any stored trouble codes.

I"m sorry, I forgot to mention that I have exchamged the coil with a coil from another car still no start, no spark. After putting the engine on TDC The timing belt looks like it might be off when I compare it from what ALLDATA has. I"ll put it where ALLdata says it should be .

Yeah, that would be a good idea.

You haven't tested anything except coil resistance, which is inconclusive. What did you use to test power to the coil?
