Thanks for both directions!

Just a side note: is there a "log off/out" for this site? Probably obvious but I don't see it.

This is info I can use! I overlooked relay testing section in FSM and yes, I will get my own continuity/voltage tester for wiring and relay tests. I do need to learn how to use it and I can find someone to explain and/or show me. Also thank you for advice on desirable DC voltage. Will then try to retest all battery to pump components along power paths (with first attention to main relay and pump relay...they did click with every battery/power connect but need to be fully tested anyway). I will retest following wiring diagram from FSM and fuel pump circuit diagram. The ignition switch is the only component that has not gotten any testing to date...and I will remove it from steering column since I can't get to it's pins in place. Too old for body "twists" :=). So the journey begins. Thank you! Please wish me success. Doug

Charles, I may have to go this route but first I will try to learn as much as I can as fast as I can! Wish I could identify FP and power link inconsistency. Perhaps a sticking relay is the answer but I still have no idea, or how to explain to someone else, why new battery caused sticking? Oh well! Have you heard of anybody good in Z work near me/us? I am leery of taking it just anywhere and having the car held hostage in someone else's garage. thank you for your kind replies...they are appreciated and renew my faith in a helping Z member! Doug P.

Thank you for directing me Zed Head. Your responses have been mostly helpful in identifying my problems. I'll try to learn more about auto electric to satisfy my fundamental problem. Okay. I really didn't find Talking Head lyrics very helpful but your last two posts contain truly legitimate opinions. Yes I can admit to enjoying driving the Z without knowing how repair it. A direction that in order to solve my "how" mystery, I need to know how to diagnose issue hands-on myself and then fix the problem. Okay, I get that too. No need access either site forum for any further Z assistance until I can troubleshoot the problem myself or locate a local source to access: which is also what I asked help in finding. I really have tried to learn from observing and asking questions from somebody in my garage or theirs... even though I have that fundamental problem lacking hands-on experience. I am able to follow the wiring diagram from the FSM even though it leads me back to the power fusible link "why" issue detailed in write up I offered. Suggested relay sticking or unknown battery mis connect could be possibllities. Clearly, I've got to learn some more new stuff beyond my ability to follow that wiring diagram! So far I have avoided throw parts at unknown problem (possible relay exception) or asking how to direct wire FP. Thanks. Doug

Yep. Zcar.com. Still have the problem. My Zcar.com postings were poor (apparently they still lack clear language trying to post what has been done) and my problem became of "no interest to that site". Here I am again on Another site attempting possible Identification of fusible link actions and fuel pump operation. Please, I still don't understand why I can't avoid "PO messed up wiring" responses..The only thing changed is AFM pinjumper wire (not an unheard of modification for ZX AFM/60mm on a built 3.1). This alteration did power FP w/ ignition "on" position, granted not factory, but worked perfectly for 15+ yrs. Rest of wiring is factory and circuits have been tested. Nothing in wiring diagram has been changed . Same wiring as before when FP engaged w/key, start and run great. I apologize if I can't understand. how wiring can be unchanged, battery changed, start of FP problem, fusible link power connections can create problem, so I can get repair help. If my attempted explanation of problem or actions is a problem then I can supply better! Regrettably If it is not in anyone's interest then I'll stop asking Z forums. Sincerely asking help. No desire to create any negatives. Doug

Hello forum! 1- I am new to this organization,. 2- I have limited mechanical skills, 3- I have no electrical system test/repair skills ...three strikes but I'm trying to get back to just driving and enjoying my 77280! At this point the Z has gone from start and run fine (even after long sit and charge/jump) and now with a new battery installed that has changed! How I ask? This starts Z mystery...how can a fuel pump operation be affected by basic battery installation or is this some kind of totally unreal freak?? I should have just kept charging and carrying jumper cables. That worked! Very long, involved chase to identify why the fuel pump (yes it works perfectly when it gets power) is not getting power from (new) battery and unchanged ignition system. When I had a Z'r helping me in my garage we/he went through all electrical circuits to get car to start and run...until ignition turned off and restart attempted...connection/disconnection repeated sequence of fusible link power wire with key in "start" would get power back to pump and start w/ run fine. Everything in wiring/ignition switch/relays and tested electrical circuits is the same but no consistent FP power...he couldn't figure it and I lost contact with him to even assist me to direct-wire pump from ignition switch. I have no one to help me now and I am mechanically dumb. I can provide anyone interested further with a detailed write-up with all procedures/results to date to answering standard "did you try" questions...unless what has been done leads directly to direction from fusible link results. I live in WNC between Asheville and Hendersonville. Is anyone close that could help diagnose/(direct wire if absolutely necessary) at my house (I will gladly pay !) Or does anyone know a highly qualified repair contact nearby??? I apologize for the essay! I can answer 90% + questions by providing the detailed write up). I at a dead end with a new battery...an on and off FP and no onsite assistance.

Hello classic Zr's. I am having fuel pump-electrical/ignition (mystery solution) "issues" with my 1977280. I am trying to find an owner, mechanic or repair shop that has extensive knowledge of fuel pump electrical circuitry. I can provide an in-depth, write-up of everything that been done/results to date...it is a bit lengthy but will be helpful to anyone trying to resolve. I had onsite assistance before Christmas from a Z owner who had got me to where I am but now is not contact ##. I live in the Asheville-Hendersonville NC area. Any contact and assistance in the WNC or upstate SC Greenville/Spartanburg area is greatly appreciated!! my name is Doug . My email address is dbparker54@yahoo.com. My mobile # is 727/804-8678. Thank you for any contact you can help me with
