idles roughly, and now gets maybe 1 MPG. Runs very rich with black smoke. Fouls all 8 plugs quickly and evenly. It often doesn't like to start - just turns and turns - this was the original problem that started before 2013, and I thought likely due to sitting for a few years(since 2007 basically).
Recently Changed - MAP Sensor, Air Charge Temp Sensor, Electronic Coolant Sensor, Fuel Pressure Regulator, Fuel Pump, Fuel Filter, Plugs - multiple times, PCV valve and intake manifold cleaned thoroughly with Seafoam and transmission fluid, both Batteries(has wheelchair lift), removed catalytic converters, replaced any hoses that were confirmed leaking
2013 tuneup. Wires, Cap and Rotor, Ignition coil and wire, PCV Valve and grommet, O2 Sensor. Tuneup didn't solve the cranking issue, so it sat a lot after 2013 also.

Sigh. I'm not the mechanic.. I'm the guy who needs the lift more frequently nowadays.. The mechanic chased the problem but didn't solve the cranking issue. He told me it was only throwing an airbag code now, but after talking around thought I might need a new ECM. So.. I bought an Innova 3145, drove it until it was hot, and got it plugged in. I think it's memory only handles 12 codes. I had to count out the last 7 myself. This is just the KOEO test..

117 ECT sensor is/was low or grounded – engine coolant temp sensor below minimum voltage. 254degrees indicated
638 TOT sensor is/was low or grounded – Transmissions below temp
126 MAP or BARO sensor out of range – “>MAP above or below normal
122 TP low (possibly grounded or open circuit) – TPS below min voltage
112 Intake Air Temperature (IAT) sensor is/was low or grounded – air charge temp sensor below minimum voltage
327 EGR feedback signal is/was low – EVR or PFE
654 Transmission selector not in PARK – Transmissions
513 Replace processor (PCM) (internal failure) - PCM internal voltage failure
553 AIRD solenoid/circuit failure – Solenoids - thermactor air diverter solenoid circuit fault
552 AIRB solenoid/circuit failure – Solenoids - thermactor air bypass solenoid circuit fault
565 Canister Purge 1 solenoid/circuit failure – Solenoids
556 Fuel pump relay primary circuit fault – Power / Fuel Pump Circuits -
558 EGR vacuum regulator solenoid/circuit failure – EVR or PFE or Solenoids
621 Solenoid/circuit failure – shift solenoid 1 – Transmissions
622 Solenoid/circuit failure – shift solenoid 2 – Transmissions
631 Overdrive Cancel Light circuit problem – Transmissions
629 Torque Converter Clutch circuit fault – Transmissions
626 Transmission Coast Clutch (CCS) Solenoid/circuit fault – Transmissions
624 Solenoid/circuit failure -Electronic Pressure Control (EPC) current is high

I can drive it once it's started, but I dare not turn it off away from home.. and I can't work on it myself. Help? Like.. please help? And a lot of thanks in advance?

 

Wow that seems like it could possibly be a bad computer or ground for the computer. Not sure how to check that.

 

That many DTC's being triggered all at once definitely signifies a problem with the ECM----get this one to a qualified mechanic ASAP for a knowledgeable diagnosis.

Could be a simple external wiring connection issue as Spaznut says or something internal to the ECM.

Good luck with this!

 

Thanks for the replies.. I'll check back in after I get it looked into.

 

It could also be that it has the wrong PCM in it right now, did you just acquire this vehicle perhaps? There should be calibration decal on the drivers door edge or pillar, that lists the correct PCM catch code for your van.

 

Nah, I bought it in 2003. Pretty sure it would be the original. I didn't think to check the door sticker for anything., though. I've just been using the vin to try to get info. Thanks. Hoping a mechanic will come out today.. can't tell ya how bad I want to dive under the hood, myself.

 

We know that feeling but remember: Look before you leap, still waters run deep and all that rot.

Good luck with this---most likely its not an overly complicated fix, just frustrating as hell know WHAT is amiss!

 

Ughh.. The shop won't even take it until next Wednesday. I grabbed the ECM code off the sticker. Can anyone decipher where I can find a 2-64K-R11 F2AE-6E061-GPD replacement, should I need one?

 

Update: Here is the computer. Three busted capacitors. I will pick up the remanufactured computer tomorrow (F2TF12A650LB Cardone #78-5302). It should be plug n play. <--Hopefully!

Model Number

1. Burnt Broken Cap

2. Burnt

3. Maybe ok cap

 

If you'll be keeping this van I'd keep the failed PCM and send it off to a repair shop. I don't mean to alarm you but that Cardone brand has never impressed me as reliable. They might be using a good process to rehab PCM's but it wouldn't hurt to have a known good PCM laying around in case this same situation visits the "new" part you have.

 

Thanks, JWA. It's unfortunately too late. It got turned in for core charge. We put in the new ecm and the van wouldn't crank.. just turned and turned. The Innova scanner got no feedback, and the AC light just blinked code 12. We decided the new one can't be good. I got a replacement and we'll try to install it today.

As far as I know, we disconnect the battery, install ecm, then reconnect the battery. Anything else we should be doing?

 

Well.. it fired right up, idles nicely and no longer smokes. The Check Engine light is still on with Airbag blinking code 12. The only thing noticeable is it shimmies on takeoff. The scanner only shows 000 and doesn't scan. Need to drive it long enough for the new ECM to re-learn.

 

MINE DID THE SAME IT IS A 1993 FORD E150 5.0 LITRE ENG. ITS SMOKED BLACK, RAN ROUGH, SMELLED HEAVY ON GAS, VERY BAD GAS MILAGE, AND BLACK SUT THE PLUGS, WHAT CAUSED IT WAS THE ECM COMPUTER WENT BAD, COSTS AROUND $250 FOR THE ECM COMPUTER PLUS $80 FOR NEW IRIDIUM PLUGS AND LABOR IF YOU DONT DO IT YOURSELF
