Chev Astro van/2000

Its not a 4cyl if its a 4.3 liter-Okay start with this

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on.

CEL is the (check engine light)-you need to have the computer scanned for code/s that maybe causing your problem or you can try below

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it

That was 2mos. Ago -scanned the computer with a scantool something is causing it pop the CEL on-

ABS is the antilocking brake system-you can get one from them or rent it-I suggest you own one for future uses-

You're welcome, Merry Christmas and Happy New Year-
