SOURCE: How do you change the headlight for a 2001 chevy cavalier

i actually just did this a couple days ago, this takes about 20 minutes and a little bit of patience. When you pop your hood you will see a protective piece of plastic over the headlights/radiator, you firstly have to remove the plastic clips holding that piece then pull that piece of plastic off, once done u will see 2 bolts holding each headlight in place, i believe it is a 9/16 socket but if not just find the one that fits, remove the 4 bolts (2 for each headlight) and pull the headlight in an up and outwards manor. if you feel any resistance do not yank look at why it is catching and clear it, then it should just pop out (the headlight and the corner piece and clipped together so dont pull it too far out) then when the bulb is accessible pull the old bulb, put the new bulb in and voila place the headlight back into position, redo the 4 bolts holding the headlights and re-attach the plastic headlight/radiator cover. Enjoy the new lights

Can you unplug one of the injectors to check for injection pulse. You should be able to unplug number 1 (next to the alternator) and number 6

2001 Chevy cavalier fiering yellow

If you mean the spark is yellow instead of blue, that means the coil no longer produces the hi voltage necessary for a blue spark. Replace the coil pack for that cylinder.

Po316 y po303 en Ford tAurud 2003

Cylinder # 3 has a misfire...#1) Defective coil on plug or the spark plug itself...#2) Contaminated fuel injector...See drawings below...The coil pack is the smaller of the two and sits to the rear of engine it is the most probable cause...Although the spark plug or the ignition wire (connection between plug and coil pack) could be at fault...so, before you invest in a new coil pack...Remove from both ends the wire from #3 and switch it with #2...if the fault code changes to p0302 that wire is bad...next Install a new set of plugs....Fault still present? replace the coil pack.....Unless recently changed new plugs and wires are a plus even if fault remains...saailer

No spark on 1987 chevy cavalier

Crank position sensor would be my guess.
Its located the center, rear engine area, mounted in the block below the ignition coil pack and DIS module.My guess is that's your culprit.
