I have a 1984 caprice classic 4dr sedan 305 CID 5.0L 4bbl carb. The battery is good, altenator is good, plugs & plug wires are good, fuel is getting to the carb, and the starter is new. The problem is the car cranks but will not start. Could it be the coil, igniton control module, or the distrbutor is out. If so, how would you test to find out which one is out? Thanks.

SOURCE: 96 Chevy Cavalier running on 2 Cylinders

You said the the 2 cylinders in the middle has no fire. That will be 2 & 3. It has 2 coil packs. One runs 1 & 4 the other runs 2 & 3. Check the coil pack that runs 2 & 3....The firing order is 1,3,4,2... It runs because it hits,miss,hits,miss....just enough to keep it running....

Disconnect the battery,Then there shoulkd be a bezel ring on the outside of dash facing you hold the switch from the back and break loose bezel ring it will turn counterclockwise as you are looking at it,make sure the new switch matches, transfer wires from old switch to new and reverse proceedure to install.

SOURCE: I need the spark plug wiring diagram for a 1994

firing order of a small block chevy engine is 1-8-4-3-6-5-7-2, clockwise-#1 on the front driver side (1,3,5,7 on driver sied, 2,4,6,8 on passenger side)-#1 should be about the 7 o'clock position, but to be certain, rotate the crank (loclkwise) until the 0 degree mark on the balancer lines up with the scale-look at the installed rotor-it is either pointed at the 7 o'clock position or the o'clock position-with the plug in #1 removed, rotate it again to see if the cylinder pushes air (compression)-that is where #1 plug wire belongs. just plug them in in order (18436572)-you will still have to time it to start, they usually need to be set a few degrees before top dead center.

I have a 1991 K-Blazer that we rebuilt a high output jasper engine for that came out of a 1984 Caprice, it keeps fouling the plugs after only running for a short while

EGR valve sticking or bad vacuum leak, might be a place to start. I presume the ECM, control module are functioning properly?

Need an emissions schamatic for my 1984 K10 silverado 305 engine

Unfortunately, there are 13 variations for this engine and year. Was this truck sold or modified for high altitude? Was it sold in California or modified to meet the CA emission standards? Does it have a manual or auto transmission? After narrowing down based on answers to these questions, there are still alternative configurations depending on the particular equipment, so look carefully at the diagrams to see which components are used on your engine. Sometimes you can match the 3 letter code for the diagram to letters in the VIN or a sticker in the engine compartment. Please let me know if you have questions.

Where is the fuel filter on 1984 Silverado 4x4 pickup with a 305 cid?

If you have the original quadrajet carb it has a small inline fuel filter located on the front of the carb. This applies to both 2bbl and 4bbl 500-650 cfm carbs
