1994 Ford Ranger 4.0 extended cab, auto 4x4, auto tranny, dana 35 front, ranger 8.8 rear, 3.73 gears, A/C.
I just finished replacing my entire Power steering system, my old high pressure hose did not have a pressure sensor so my new one does not either. Recent work includes replacing rocker arms, pushrods, green/red striped wire between the alternator and the instrument cluster, the PO replaced the radiator the day I bought the truck.
When I turned on my truck after replacing the PS system my CEL turned on, this wasn't a big deal until I couldn't start the car after I shut it off. I did the KOER and the KOEO tests and here are the flashes I received in the exact order I received them.
KOEO: 118 118 118 157 118 157
KOER: 998 118 998 118 (after the last 11 the first time the CEL flashed 5 times but did not complete because the engine shut itself off, I did this test twice and the second time I got 118 as the last code)
Note: neither test gave me the engine ID or asked me to goose the engine.
I've checked my Haynes and as far as I can tell from these are what those codes mean:
998: Hard fault present
118: Coolant temperature sensor above maximum voltage/indicates below -40 degrees F (Note: the temp gauge still measures temperature like it did before)
157: Mass Air Flow sensor below minimum voltage.
I'm going to take it to a shop to have the codes read right after the weekend. Right now, I've got no clue what's wrong and I need help.
For a refresher here are the symptoms:
1. My engine will not start hot, it just rotates, seems I have no spark when hot since I can hear the fuel pump, sometimes holding the throttle open will allow it to start but only after it has cooled off a little.
2. My engine shuts itself off, I'm unclear if this is because it is hot or for some other reason.
3. My engine runs a little rough, there's just a slight shake to it.
4? Preexisting and probably unrelated condition, but my lifters make some noise until warm.
RESOLVED: Replaced my smashed ECT sensor and that took care of it.
