Default Trouble with '92 legacy 2.2L N.A.

I have searched on this subject and have found a few things but maybe someone can help me or tell me where to look.

I have a 92 lecacy 2.2L non turbo and it runs well except lately it has been starting kind of hard when its warm out. It always starts right up with ease in the morning before i go to work. Then I get to work, park it for 3 or 4 hours. when I try to start it after it has been sitting in the sun for that time it is harder to start. I can always get it to start eventually but i just want to fix it so i don't have this problem. Sometimes when i finally do get it started it runs really crappy almost like not all of the cylinders are working. when this happens i just shut it off and start it again and it is fine. I am at a loss as to what is wrong with it as i have replaced the obvious things that i could think of. Here is what i have replaced.

Spark plugs/wires
ignition coil
cts (coolant temp. sensor)
O2 sensor
fuel pump

If anyone has any ideas i would much appreciate it

thanks,

I wish I could help. I had a similar problem with my 99L (also 2.2L).
Mine went away with new plugs (I think at least). It only happened like 2x per year and only when it was cool in the morning and blazing hot in the afternoon.

Fuel pressure regulator may be crapped out; if it lets pressure leak out of the lines it won't start as well, because, well, it won't have as much fuel to work with. The fact that you can stop it and restart and it works just fine seems to support that, because at that point the system was come up to full pressure, but I could be wrong.

That is what i wanted to hear. The fuel pressure regulator was my next guess. i checked it out and there is no leakage or anything. i was also thinking it might be the air pressure sensor. i think i will try the fpr and see if that works. i will post how it turns out.

thanks again,

adam

Does the engine run any worse or better once it's reached normal operating temp....compared to when you just start it up...either in the morning or afternoon?

It is usually fine once it gets up to normal op temp. Last night I did a self diagnostic test and figured out that the purge control solenoid was defective. I am going to replace that and see if that might be it. I will post the results.

After pulling the check engine code from my ecu i got a code 35 which is a faulty purge control valve solenoid. I replaced that on friday and the car seems to be starting easier. it did start kind of hard once this weekend but not nearly as much as it normally does. I still suspect that the fuel pressure regulator is shot but from what i have read it seems like your car will barley run if the fpr is dead. I checked the price for one and it was $144 at nappa so i think i will wait on that. haven't had a check engine code at all eigher since i fixed the purge control valve.

If the purge solenoid fails open, it can cause issues with starting and idling especially.

If your fpr fails, ie the diaphragm isn't doing anything, you'll just have a higher fuel pressure at idle, and will run richer then you should. That shouldn't cause a hard start situation....infact the fpr really doesn't play any role in fuel pressure regulation until the car is running. So I wouldn't worry about the fpr.

Another thing you might want to do is reset the ECU. Pull fuse 14 EGI/TCU fuse for 20 minutes or so.

Doesn't pulling the negative batery cable acheive the same purpose? I just pulled the fuse anyway like you said but there were no codes left after i pulled the negative batery cable.

Yes, pulling the neg battery cable will do the same thing. Personally I think the fuse is easier....just me I guess.
