Will the OBD problem codes be stored by cranking a non-starting engine, or does the engine actually have to fire and run for the code to occur? I have a non starting non-turbo, 561 ECU (which works fine in my 89 244.) The car stopped suddenly, wouldn't re-start. I'm getting fuel at the rail, good strong spark. I get good strong cranking, but no fire. After cranking, I checked the OBD, and get a 1-1-1 in both modes. (this was after I pulled the battery cable to clean the posts, thereby clearing out any existing codes. Did not get check engine lite, and the car passed NJ's strict emissions testing about two weeks ago.) Anyway, I was wondering if problem codes will generate merely by cranking.
I ran all of the other tests from the OBD, the injectors all seems OK, TPS is operating properly, RPM sensor test is ok, and the tach bounces when I crank.
All the pertinent relays, switches, fuses check out ok. I've replaced the cap, rotor, plugs, and flame trap (really cruddy) and cleaned the throttle body (lots of scum in there.) Coil works in my 244.
My next best guess is that while I'm getting fuel at the rail, I'm either not getting enough fuel, or enough pressure. The main pump runs for about two seconds at the KP II position, and the feed hose to the main pump pressurizes, I can feel it stiffen. I've read the posts and FAQs about the pre-pump, sock filter, 1/2 tank of gas and and air in the system caused short hose deterioration, so my next step, as soon as it stops raining, is to replace the in tank pump and filter.
Any helpful thoughts?
