92 RS still having issues
92 RS still having issues
I have been trying to figure this out for two weeks now...
I have spark going to the plugs, but the plugs look like this:

Order is right is front of car, left is rear so 1 and 5 look the best. The car is running rich and I can smell fuel on the plugs. My question is could it just be that I need new plugs, do I need to clean the injectors, or stuck lifter? I have 45-50 lbs of pressure at the fuel rail and good spark to the plug. The car will not start without starter fluid and it will not idle at all. However if I floor it, it goes to maybe 2k rpm and dies unless I let up and do it again. It also loops like I have an agressive cam.
Any help is appreciated.

Re: 92 RS still having issues
The last plug looks awfully dry compared to the rest, I think perhaps you are only running on 5 cylinders. I would be less worried about the wet plugs that all look the same, and more worried about the one that "One of these things is not like the others".
Imo, figure out why one is dry, then worry about them being wet, its where I would start anyways. I would mainly suspect the injector on that port, can't really think of much else that would cause it to be dry. Its more likely that you have an issue in 1 cylinder than 5.

I was thinking that one of the first things I did was change the fuel pump to this one https://www.napaonline.com/Catalog/C...P_RecType%3aA). I noticed that its listed as: Gallons Per Hour : 43.50 and Fuel Pump Pressure Rating : 28 PSI. Is that enough to run the car? Everything else I see is 40 free flow and min 65 to max 95psi.

Re: 92 RS still having issues
Based on what you've posted, I have to ask this; even if you use starter fluid, will your car run more than 3 seconds?
My guess would be that you have a VATS issue. Have you looked into a new key? If the chip in ur key is worn out, that will cause a start then die condition. You may have either a worn out key or a worn out ignition cylinder. I dont have any personal experience, but based on what ive seen on this board, that would be my first guess.

Re: 92 RS still having issues
From what I remember, VATS will let the engine run for 2-3 seconds, then die. I would suspect VATS based on your symptoms and the codes youre setting, the codes being the biggest flag thrown up. The key would be the first place to start, then the ignition cylinder next.
Anyone with actual VATS experience want to chime in?

Re: 92 RS still having issues
It sounds like you have a VATS issue. The vats system keeps the injectors from pulsing and sometimes keeps the starter from engaging depending on how it failed and if someone has messed with your starter relay. From your post it looks like you have fuel pressure at the fuel rail and you have spark so you need to check if your injectors are pulsing. Since your car has a vats code I'm going to say thats your problem but another problem with these cars is a shorted injector that will also mimic the same symtoms. Do not change your fuel pump if you have a problem with the vats system it will be a waste of money. Does your car have a security light in your insterment cluster? It should come on with the key on and go off after a few seconds if it stays on the car should not start.

Re: 92 RS still having issues
Ok, sounds like you had a fuel pump going out, after you change the fuel pump if you are not getting a injector pulse I have seen where the ignition cylinder wires break and it keeps the security light from coming on at all (no bulb test or anything) and this will trigger the vats system and keep the car from starting . Also could be a shorted injector. Since were talking alot about the vats system does you car have it? Does it have a chip in the key?
