Current draw Reply #15 – May 03, 2009, 04:37:22 PM Thanks, did it and it primes. Now I guess either I have a bad computer, or I mess up the wiring for the mass air... Quote Selected

Current draw Reply #17 – May 03, 2009, 07:53:26 PM Sorry. I meant I did the test. Jumping it made the pump run. Key still doesn't work. Quote Selected

Current draw Reply #19 – May 03, 2009, 09:01:03 PM No. Pressure got up around 40 when I tried it. Quote Selected
Current draw Reply #20 – May 03, 2009, 10:37:27 PM Sounds like the EEC is bad.Well let me rethink that.You said earlier it pulsed the injectors. Is that still the case? Quote Selected
Current draw Reply #21 – May 09, 2009, 08:28:31 PM I was about to post they were, but then tested it, and sure enough.... no clicking...It all happened after we took off the upper manifold to check the injectors. But what could we have hit up there? Quote Selected

But what could we have hit up there?Don't know, but the ECC is not working for some reason.The only thing I can think of other than it being bad is voltages and grounds.Your negative battery cable should have a small BK/LG pigtail wire that goes to a one wire connector near the battery. This is the ground wire for the EEC. It goes to EEC pins 40 and 60.The EEC also has a chassis ground on pin 20. This wire goes to the cowl near the EEC.EEC pin 1 is hot at all times.EEC pins 37 and 57 are hot in start or run. Quote Selected

Current draw Reply #24 – May 10, 2009, 10:19:25 AM No, I bought the kit it mentioned and used the instructions that came with it. Quote Selected
Current draw Reply #25 – May 10, 2009, 05:33:28 PM If the TPS ground is open, the EEC will enter dechoke mode and shut down the injectors... Need to verify the voltage back to the EEC is at less than 1v... If it's over approx 4v, the injectors will be shut off... Quote Selected
Current draw Reply #26 – May 14, 2009, 09:44:20 PM Ok, all those pins check out. Mass air wires have power to, so the wirings ok.What pin is the TPS sensor? Quote Selected
Current draw Reply #27 – May 14, 2009, 09:58:32 PM with the tps still plugged in,,,,,,,,turn on keyground your neg meter lead to chassis or engineback probe the tps connector green wirevoltage should be less than 1VDC. Quote Selected

Current draw Reply #29 – May 15, 2009, 12:49:48 AM Well, figured out the TPS problem.... brother unplugged the distributor.... why, I'll never know.... I'll still test it tomorrow.So I guess that puts it back to bad ECU. Fuel pump still doesn't prime. Quote Selected
