You are a OBD 1 and there is a connection for that,you could jump two wire and read the Check engine light flashes, Inside your distributor is a ignition control module, when you vehicle does not start you need to check for spark,with a sparkplug 1/4 from engine ground have someone crank the car if there is no spark a ignition module will be needed.I start the car (1991 Chevy Caprice Classic 305 lt - 1_5_2013_6_16_46_pm.jpg

Could be any one, or more, of the following -

Plugged injector
Bad plug wire
Fouled plug
Crossed plug wires (hard to tell sometimes on V-8s that run smooth anyway)
Vacuum leak
Leaky EGR valve
Shifted timing sensor

Scan engine for codes and proceed from there.

There is a product called RXP (available here in Texas) that will clean up an engine and gas. Its pretty awesome stuff, and this coming from a person who doesn't really believe in additives.

SOURCE: 1994 gmc safair 4.3 wont run at idle and bad

Is the "service engine" light on at all?
If so, what codes are present.
Have you checked the EGR valve. If the valve is stuck, the engine will idle very poorly. You can remove it and clean the carbon deposites and make sure it moves freely.
The EVAP purge solenoid will also cause an idle problem but should show up as a service engine light problem.
Let me know.

SOURCE: i have a 89 s10 pick upwith a 2.5L did a tune up

Check the fuses and relay to the fuel pump, the relay is in the firewall just left to the brake booster, not sure which one of two relays there but you can switch them with one another. The other thing to is check if there is fuel pressure from the shredder valve which is a valve along the fuel line before it enters the fuel pressure regulator. Just follow the fuel line from the throttle body to the back of the engine and you'll run in to the shredder valve. It looks like a air valve from a tire. Push the valve like your letting air out but gas will come out it self so use caution, if you can rent a fuel pressure gauge. That is where you hook it up to and you need 60PSI to activate the injectors. If fuel pump is working then try replacing the fuel filter first since that's cheap and easy to do. The filter is in the inside frame rail under the drive and you can change it with simple tools. Good luck and keep me posted. be goad to help

SOURCE: I have a 1994 chevy k1500 preignition knock

open the intake manifold by removing the air cleaner and or hose look on the back side of the plate to see if there is varnish and gum if there is you need to do a top engine clean, You must understand that running that kind of gas will cause varnish and carbon buildup on the pistons and valves. This causes the knock sensor to not to be able to adjust for compression change. It can only advance the timing 50% once the carbon build up is to much it will start knocking. If you want to receive instructions on how to fix this then rate me post a comment and I will give you the two page answer on how to do this. Unless you want to keep buying parts. your choice. I will no longer post it here as I see some think they can just take my answers and copy them.

What engine of other cars could fit in Chevy caprice 82-85,

almost every rear drive drive full size used the 305 V8, so u can get an engine from a Buick La sabre, Pontiac bonneville and firebird, also Oldsmobile 88, and don't forget Camaro. any 305 chevy V8 will bolt in, also the 350 V8 will bolt in, this is a much better choice..
