AE 86 Starting problem

[Michi]

Hello. There is an starting problem with an AE86. I'll explain it.
The car was running great some months ago. Then it was parked in the street (still running fine) and when tried to start it the next day it didn't do it.
The starting motor turns and turns... but the engine doesn't fire even once. Then we tried to start it pushing, but it was useless.
We have check the spark in the HT lead whit a tester, and it lights when the starter is turning the engine, so we thing tha the ignition is OK.
Is there an easy way to check the fuel at the injectors when trying to start? Can you explain it?
Thank you.

loosen the cold-start injector fuel line going to the manifold and give it a blip of the starter/if it squirts you have fuel.

Ok. So, the cold start injector should work while cranking.

Is this the position of the cold start valve?



Thank you Ivan.

Yes... on the side of the intake plenum. It takes a fuel feed from the
common fuel rail, but only squirts during cranking with a cold engine
(does not squirt with a hot engine).

Check you have 12 volts on one side of the injector plugs, with the
key in the "ON" position. Pull the plugs off the injector to test them.

A new set of sparkplugs (cheap ones are fine) is always good.

Oh, and have a fire extinguisher handy when checking fuel flow

Cheers...
