  1. Thanks for the info... Does the speed sensor pulse = Speed Sensor line on ECU to GROUND? Making a 35mph pulse generator is an interesting idea... The ECU is supposed to shut off the injector if you're going X ammount of MPH, Throttle isn't pushed down (to save gas while coasting) If a pulse generator is hooked up, telling ECU the vehicle is always moving, won't the injector fail to open and give it gas? IE, fire up the vehicle, drive 5mph up hill, the injector should stop opening (getting 35mph signal), and engine would stop running? Rich
  2. I tested from ECU to TPS, everything was at about 4ohms... I adjusted the TPS again, and trouble code went away! The idle switch wasn't coming on at the correct time. The ECU is happily flashing 5. Thanks for the help guys! Now to get a speed sensor hooked up.
  3. RE: Naru (and everyone else who is kind enough to reply) Thanks for the info. I will do some more tests on the harness. The injector + and - were throwing a code, abnormal output. I soldered in 2 new wires between ECU and injector, made the code go away... Seems strange that the wires could go bad like this. Maybe they got water underneith the insulation and corroded? I've had year 1950 vehicles whose wiring was fine... I guess none of them were that sensitive to faults though. I'll report what I find later today... Have fun! Rich
  4. RE: Gloyale Thanks a bunch! I will try this later. I don't have a speed sensor in the vehicle yet... It's gotta be some sort of magnetic switch mounted to the frame, and a magnet on the axle or something? Maybe within the speedometer? (this is a transplant into a VW bus) I would like to put a speed sensor on the vehicle. Do you guys know how many pulses the sensor should send the computer per ?MPH? or ?AXLE ROTATION? so I can mount one? I have a magnetic switch and some magnets, I just don't know what kinda RPM it sends back to the computer. Rich
  5. You said "put 37 to 42 to READ mode" The connector on the end of the harness that goes to the ECU does not have a pin 37 (no conductor at that position, no wire coming out the other side).. Any other ideas? Thanks! Rich in Sac
  6. in the manual, NO leads to "REPLACE ECU"... I am doubting that the ECU is bad. When electronics fail, they usually fail to the point of not working... Update: I was watching the ECU light flash. I pulled the throttle all the way open. the light starts flashing specification code (meaning computer and sensors OK). I release throttle. Error code 31. I pull throttle all the way. Specification code, no errors. Slowly close throttle. It flashes spec code until the idle switch gets pressed within the sensor... then back to code 31 Any ideas besides replacing computer? I guess I'll grab one at the junkyard next time I'm there... The engine runs great. Starts right up. Cimbs hills, Idles fine. Rich
  7. So: Pin 31 to pin 42 (GND) to go into the test mode. (31 is labeled TEST MODE CONNECTOR in FSM).... While in TEST MODE, with engine OFF, IGNITION power ON, the ECU light shows specification code (in my case, code 5). The fuel pump turns on/off intermittently. This is normal according to the manual Pin 39 to pin 42. To clear the memory connect (39 is labeled CLEAR MEMORY in FSM). I have not got the clear memory mode to work. There is also READ MEMORY mode... Do you know which pin this would be on the ECU? Rich
  8. Says throttle position sensor is acting up. I checked the sensor without connector plugged in. Everything with sensor is OK. I do troubleshoot on page 62 in FSM. resistance between terminal 26 and 35 is supposed to be 3.5k to 6.5kohms. I get 4.25k.. so thats OK I check resistance between terminal 25 and 35. Manual says its supposed to be less than 1k when throttle closed. I get 220ohms. so that's OK Manual says it should be greater than 2.4kohms when throttle is fully open. I get 3k ohms. so that's ok too... Next step says: "check if terminals 25,26, and 35 are open or disconnected" NO--->replace ECU YES--->repair terminal or harness ----------------------------------- I don't understand this step. How do I check if they are open or disconnected? IE, one lead of multimeter on the pins one by one, but what does other lead of meter go to? Am I checking the entire harness, IE from the throttle position sensor to the ECU connector??? Rich From Sac
  9. RE: cougar That's exactly what I was looking for.. Thanks a bunch! Rich
  10. To set timing on EA82 SPFI, you need to plug two connectors together, right under the dash, next to the computer... I would really appreciate it if someone could use their multimeter and figure out which pins on the computer this connects to ! I did a transplant, EA81 into 1973 VW bus. Carb sucked (ratsnest computer controlled carb) so I tried VW carb, too small. I upgraded to SPFI, but cut the test connector out when doing the switch over... If someone will test for continuity between the "test connectors" and the computer pins, I'll send them something nice :-) ----Rich near Sac, CAlifornia
  11. Took a bit of reading to figure out dist. turns counter clockwise... had me scratching my head for a while... Runs Great! It's spitting out error 31, throttle pos problem. These engines are awesome! --Rich, near sac, california
  12. I cannot find this anywhere. Please fill in the blanks! position number drivers front ___ drivers rear ___ passengers front ___ passengers rear ___ front = front of car closest to radiator rear = rear of car, closest to transmission I read that the order is 1,3,2,4. I have received conflicting emails regarding the cylinder #'s
  13. I ordered and received a new head gasket. Interesting, this is very different than the first gasket I put on... the first (which appears may have leaked, or it may have been manifold gasket) was flat black colored, looked kind of like charcoal. It felt rough/uneven surface. the one I just bought is deep dark red/brown, shiny surface, feels like soft rubber coating.
  14. anybody ever get a chance to do this?
  15. forgot to mention: I have never got this engine over about 200 degree F. It has reconditioned heads, new bearings, new rings.
