    This is a CT car and I am in NY so no diagnostic button to push. The car was not running when I measured Pin 6 to pin 2. Hope this helps.\ FYI I had charged the battery the day before so there is either a voltage drain or the multiple starting attempts are quickly draining the battery which is...

    Did the duty cycle test. Pin 2 and 6 were 11.86 about same voltage as direct from battery. Pin 2 am 3 zero voltage and this should be helpful to you. ThE car started fine even with low voltage. Ran as usual and won't idle. I didn't do fuel pump test as I am hoping the duty test results will be...

    Will do and I'll report back with the fuel pump tests results. Thank you:)

    Here is an idea I am unsure of. When I first got the car in 7/18 it would only cold start and the owner said it just needed the CO adjusted. I leaned the air/fuel mixture slowly and it began to run better, then blew black smoke (rich) and eventually would start cold and hot and run/drive fine...

    I am with you now:). I'll get to it this week and report back to you. Thanks

    I have to put it back on jack stands in the back and set up test rig again. Can you tell me where you are going with this if one pump being disconnected does change something? I don't feel it's mechanical as it only started after my brain fart while charging the battery. Thanks G:)

    Finally some good news. The voltage at the forward pump is 13,68 no matter the rpms and the aft pump is 12.89 again no matter the revs. What's next :) ?. See link below to a manual page I found on line. I think the first system is what applies here but not sure as I don't think I have Y8, idle...

    PS I replaced EHA and no change.

    Thanks for the reminder. ( see# 53) Not sure but will try. What gauge wire can I use for the long leads and how to I hook up the volt meter? In line so current flows thru it and back to pump? There are two pumps. Should I test each alone or some other arrangement? I know its a stupid...

    I read up on checking the fuel pressure and its not for me. Way too scary messing with gasoline etc. So its the end of the road for this dreamer. I'll give it until the craigslist ad expires and if not sold I'll donate it to a local non-profit. So if any of you are near to 10576 there are a...

    I only have a cylinder compression kit. Can i use this to safely test the fuel pressure? I found below link for the correct way to do it and it is beyond my tools or skill level. I just don't get why the fuel pressure is in question as the engine runs strong when I keep the revs up and will...

    D: this is with me using the acelerator pedal. Will not idle on its own. J: I was asking about if I put in a new EHA. I seems tricky to adjust once it's replaced.

    Here is Post#40 pic at last. I have done a bunch more reading. My EHA was wet at the plugs etc so I guess its shot. New is expensive but worth it to me if it fixes the issues. I can't figure out if its plug and play or I have to adjust something inside the EHA by trial and error and also adjust...

    Forgot the pic of the EHA location in case its different than yours. Black box to left of injector unit.
