Re: no fuel pump, no spark, no power to fuse

I would bet on ignition lock since you dont even have power coming to the fuse... and wiggling is also telltale that you got problems with ignition cylinder.

Re: Corsica misfiring after rain (nowadays problem with IAC valve)

Running soon to dead end here. Iac seem to act ok. Even though i unplug i when car is running warm, i check its not stuck closed, I still have to crank to get it started. New notice: if i crank in short (i.e 1 second) cycles, after few cycles (around 5) it starts right up. Still fuel pressure? Press...

Re: wrong speed displaed on speedometer GTZ 1992

20kph difference between wheels and gauge is quite normal... just get used to it. :)

Re: What (scan) tools do you use?

Hmm, sounds dangerous for me. :D

I already own 2.3t Saab 9-5 as my daily driver, Trionic 7 box and its tuneability (re85 + 240hp) leads to endless hunger...

I'll take look to the cable and sw for sure, might be soon if I cant sort out my IAC problems in any other way.

Re: Corsica misfiring after rain (nowadays problem with IAC valve)

My idle is quite fine, though its sometimes quite low, around 600rpm. Only real problem is starting, where IAC seem to have effect on, since with the old, broken one the car started just fine (in most situations). I actually took picture of the iacs four wires, but is there somewhere pinout so I cou...

Re: What (scan) tools do you use?

Re: What (scan) tools do you use?

Hmm, since this thread seem to be suitable for my little question I guess im going with this.

My Corsica is -93, with ALDL. Does that mean its obd1? What kind of data I cant get out of that box (except jumping codes with a+ b pins of course), and specially, with what tool?

Re: Corsica misfiring after rain (nowadays problem with IAC valve)

Moving to next suspect: IAC valve operation. Seems like also my current IAC (stolen from another Corsica) is also stuck. Cant move the pintle with my fingers? If i remember it right, I could move my previous IAC pintle easily with fingers when I cleaned it up. I also managed to find out from interne...

Re: Corsica misfiring after rain (nowadays problem with IAC valve)

Ok, Injectors tested. No leaks. Put power on while all injectors were connected. When you put power on with key, each injector sprays one load of gas. I think this is supposed to happen? Made two leak tests: First on, i disconnected each injector wires, and put full pressure on the line. None of the...

Re: Corsica misfiring after rain

Nah, dont worry about it. Of course I put jars under injectors. Its also -5 to -10 here in Finland so nothing burns nearby. Gotta take look for the relay... I actually am coming to conclusion that its still something with iac valve. The engine started quite fine with broken iac (stuck), after i put ...

Re: Corsica misfiring after rain

Hmm, ok. I'll check it out and give really short pulses. Its safe to run start motor while injectors are pulled out?

Also, where is fuel pump relay and how to bypass it? To get pump run constantly?

Do you guys think lamda would be the culprit for hard start while hot?

Re: Corsica misfiring after rain

Hm. I already thought im gonna give max 1 second pulses to them with wires, to prevent overheat or sth.

Maybe I'll hook up 9v battery also.

Re: Corsica misfiring after rain

Yeah took the upper intake apart today. No big deal, took like 2 hours while doing it carefully (first time for me with this engine). Didnt have to touch alternator. Took out EGR, tbi body and cable bracket, map and air intake box of course. Already removed four bolts holding the rail, and also remo...
