My chev spark 1.0 it shows engine lite when I start the engine

You drove with a flashing check engine light and then with it on solid. Flashing check engine light means STOP DRIVING and get it fixed. So this sounds like an abused and neglected car to me. Get the trouble codes read that are stored in the computer. Check for good fuel pressure and spark. Fix one or both.

Have the code/s read. Auto parts store do it for free. Repost.

go on line for firing orders for chev v8 engines and there will be diagrams to show you where everything is supposed to go for al GM engines.l

Disconnect the battery for 1 hour. If the problem was fixed, the light should go off.

So, do you hear the pump buzz on, when key is on? If that's good, then check your ignition circuit: check for spark at a plug. Use insulated pliers, hold end of plug wire 1/4 inch form engine bolt or ground source. When cranked, you should see a bright blue spark. Yes? Try another plug wire, too. No? Try another plug wire. If you have NO spark, could be your coil, coil pack, crank position sensor, ignition module. I would recommend using a diagnostic flow-chart to go through the ignition circuit. That way, you are not replacing unecessary parts_Expensive! Of course, if you have spark at plugs, your ignition circuit is good! Then you have to look further, like your injector circuit. Good luck.

When facing the engine, the spark plugs are numbered like this (from left to right):
1 2 3 4

They fire in this order: 1 3 4 2

Source

check fuel pressure, check fuel pressure regulator, change fuel filter. If fuel pressure is low it could be a bad pump, a clogged filter, or a malfunctioning fuel pressure regulator. If all those check out, then check crankshaft and camshaft position sensors.

Firing Orders NOTE: To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.
3.1L (VIN M) engine
Firing order: 1-2-3-4-5-6
Distributorless Ignition System

hi...
1.try checking the clearance in the spark plug if you have insufficient or more clearance you wont get spark check this.
2.check the wire coming to the spark plug.if power is not coming to spark plug there wil be discontinuity in the wire try replace it.

if you get the information which you needed please vote me by clicking the thumbs present in the underside of the page.

Have you checked the fuses? I think there are 2 ECM fuses if either one blows there will be no spark.
