1999 Chevrolet S10 Base 4 Cyl 2.20L

Engine

99 2.2l S10 No Spark

My s10 all of a sudden died one day and it won't start back. Parts I have replace are crank sensor, icm, oil sending unit, head gaskets, plugs. I have tried just about everything but I still don't get spark at the plugs.

First question - how many miles are on the vehicle? What has been tested so far?

The engine needs proper ratios of the following; air, fuel, ignition (spark) to start and run. Before replacing any parts, you must test and diagnose for these basic conditions:

Test for spark at the spark plugs and at the ignition coils.

Test for air flow at the air filter and intake - no leaks, no clogged filter.

Test for fuel pressure and presence at the fuel pump outlet and at the engine fuel rail.
