1994 Chevrolet Caprice - Answered Questions & Fixed issues

quite a few reasons ----needs tune up --air filer--plugs--plug wires --cap /rotor---fuel pump --fuel filter--cat converter --throttle body --vacuum leak--gasket leak--carbon build up --these are a few theirs plenty more

not starving fuel but "flooding out" and putting unburnt fuel in the exhaust system which ignites and damages mufflers and cat converters check for excessive fuel pressure or bad /leaking injectors

You have spark/arc at the plug. Look at timing, fuel pressure. Get the engine at TDC #1, compression stroke.. Pull the distributor cap, see where the rotor button is setting. Tab should be pointing at the #1 cylinder. Fuel pressure , Guessing, 30 to 40 pounds. Been to long and you have to check at the fuel filter. No shrader valve for this.

A new timing chain will not affect ignition timing unless the chain is incorrectly installed then the whole engine is out of time. Why not state what the problem is instead of a generic question like you posted.

Take the aircleaner off all the way to the carb/intake and inspect every piece that comes apart for blockages.

It likely needs a new unit, that models ABS unit is not servicable. If it stayed out, then came on AFTER you started driving then it would be a bad wheel speed sensor, but no such luck if it's always on.

If that is an aftermarket remote or security, tear it out and repair any cut wires as you go. You car will start then.

In the under hood fuse/relay box !

Just get standred plugs wire plugs arn't going to improve the proformance . If you want to do something that will help replace the wires cap and rotor you will feel a differance and generaly run better.

depends on the mileage on it...and if the price is so cheap...? - if the actual owner had it looking like a piece of s.... it is surely not well serviced and such a big car has many parts which could go broken after 21years of service.... - the rear windows are probably only locked (child safety) better go for a smaller, newer car if you cannot fix anything by yourself... 1994 Chevrolet Caprice Body Mechanical Trim Parts PartsGeek

if vehicle starts, you can usually rule out ignition

what part of the ignition was replaced?

when you first try getting fuel going. you may have to turn the key on and off a few times to build up pressure. if you can hear the pump working it will change when it builds up pressure. if its not then I would say you have a line leaking. check all your connections before you have a fire

Are there any MiL codes present? Maybe the exhaust is clogged.

i beleve your thermostat stuck open

Check your throttle position sensor, sounds like its going bad. Simple test to check voltage. Before you do confirm your engine has proper fuel pressure.

Check for spark when it dies. Coils tend to die when they are hot.

It could be your starter,i had one on a ford torino years ago that did the same thing and it was a faulty starter

Check to make sure the exhaust is not stopped up.

is by the evaporator pipe
