That's what I was thinking but I wanted to rule everything else out first
Yeah I think it was converted because the ecu I have now is from an obd1. So the crank sensor couldn't be causing a no fuel no spark?
No it's always on even when I don't have it jumped.
Did you get any other codes?
Nope. The cel just stays on steady. No other codes or anything.
I hope that's what it is cause after that I have no idea where to look. Lol I'm supposed to try another one tomorrow. Keeping my fingers crossed.
How many grounds are there? I've checked all the grounds under hood and all are fine. I just cleaned the g101 a few days ago actually. Checked main relay yesterday and got the correct results. Replaced fuses 24 and 31 this past weekend as well.
I honestly don't remember. But G101 feeds the main replay for the fuel pump, so if that ground is good, the main relay is good, and the fuel pump still isn't kicking in, I don't think it's a grounding issue.
Thanks for the picture. I tested the map sensor about a week ago and I remember getting voltage just don't remember if it was 5.I honestly don't remember. But G101 feeds the main replay for the fuel pump, so if that ground is good, the main relay is good, and the fuel pump still isn't kicking in, I don't think it's a grounding issue.
If you unplug the Map sensor connector, turn the key to on II, then test voltage to body ground at the terminals for the YEL/RED wire and WHT wire within the connector, do you get 5V?
If you can, test it again, and test both terminals in that connector. Both should supply 5v individually. Power from these terminals comes from the ECU.
you should 3 main grounds harness to thermostate, valve cover to chassis, tranmission to chassis
Yeah those were the ones I checked. All were good. I put the car in the 2 position and removed the map senor,tps sensor and one more at a time but the cel still stayed on.
You can test from the terminals inside the map sensor connector. I may have worded that oddly, I was just saying that voltage to that sensor is supplied by the ECU, so you don't get 5V from those connections, that's bad. 5V to one but not the other would indicate an issue with that wire, 5V to neither terminal would indicate an issue with the ECU. You said you got voltage to one, which is a sign that ECU is functioning. But it doesn't hurt to test both and ensure that it's 5V.
also you should see the voltage change from 0-5v
Ok. I think I'll be working late so I'll check them again tomorrow. I know I tested it but just can't remember the results.
So it wouldn't be a bad ecu then?? If I can't get it running I'll more than likely get a prelude lol
I was looking at a 97. Not sure yet. Hoping to get this car running by Friday.
