1988 thunderbird v6 problems Reply #31 – June 02, 2016, 09:49:09 AM I got spark not sure what I did but I hooked up a different coil and just sat it by the other one still mounted and it fell over I started getting spark but now I'm not. So I guess I may have a short some where? Quote Selected

1988 thunderbird v6 problems Reply #33 – June 02, 2016, 05:31:37 PM I checked voltage to coil again and was only getting 6 then would drop down to 4 while cranking? Quote Selected

Sounds like you need to get the battery charged up. There is going to be some voltage drop while cranking it over.QuoteBoothcody22 I got spark not sure what I did but I hooked up a different coil and just sat it by the other one still mounted and it fell over I started getting spark but now I'm not. So I guess I may have a short some where? Maybe try hooking the coil directly to the battery with a jumper wire. If it happens to start the only way to shut it down is to disconnect the jumper wire. Check the wiring and connections over. Check for continuity on each side of the connectors, wiggle the wires while doing so. If you are testing with things unplugged and it tests good on that end it doesn't mean it is getting out of the other side of the connector when it is plugged back in. Quote Selected
1988 thunderbird v6 problems Reply #35 – June 02, 2016, 06:44:31 PM Well she runs! Only problem is I unhooked that timing jumper which ik is supposed to be in but what does that mean? Also I grabbed it while running so I became the jumper I advise never doing that lol Quote Selected
1988 thunderbird v6 problems Reply #36 – June 02, 2016, 06:49:15 PM The timing jumper plug basically removes the computer from modifying ignition related stuff. Essentially running in limp mode.Now that you got it so it can run, put that jumper back in, clear codes or disconnect the computer over night, and try to start it again. If it won't start, pull codes and see what really going on. There are only a handful of sensors that will prevent the car from starting with the jumper in vs jumper out.Hopefully we can get ya going.

1988 thunderbird v6 problems Reply #37 – June 03, 2016, 12:13:12 AM It would try to start when I put it back in. The code I'm getting is either 4 or 41 Quote Selected
1988 thunderbird v6 problems Reply #38 – June 03, 2016, 12:49:56 AM Could it be the eec or some kind of ignition relay Ik a guy that swears that's what he did to fix his. The eec was getting really hot Quote Selected
1988 thunderbird v6 problems Reply #39 – June 03, 2016, 09:31:50 AM You mentioned someone had put a new distributor in it. Have you had a timing light on it? Quote Selected

1988 thunderbird v6 problems Reply #41 – June 03, 2016, 04:56:55 PM New relay didn't help. So is the computer the only thing left? Quote Selected
1988 thunderbird v6 problems Reply #42 – June 03, 2016, 06:12:20 PM If it runs without the spout pull it, start it, check the base timing just to make sure it is set right. Quote Selected
1988 thunderbird v6 problems Reply #43 – June 03, 2016, 06:20:03 PM Oh ya ok in gonna try timing tomorrow Quote Selected
