1988 thunderbird v6 problems May 27, 2016, 02:51:22 PM The car has issues starting but once you get it going it runs fine. If you let it idle for a while it will stall then you can't get it to start. I did the self diagnostics test and got 11 at first then I couldn't tell if it was giving me code 84 or 184 anyone have any idea? It apparently has a new fuel pump I couldn't get the car to run long but the fuel pressure gauge was at 30 Quote Selected

1988 thunderbird v6 problems Reply #2 – May 28, 2016, 04:42:01 AM There is a small rubber hose that connects the fuel pump to the fuel hat and lines. Sometimes that goes bad.If the pump is running and you can hear it making nose when you cycle the key on and off, it could be that. See if it will fire up on starting fluid just to make sure it is fuel and not spark related. The computer needs to run to fire the fuel pump relay.In the mean time, google sbftech efi no start and run through the steps there. It will pinpoint the problem, if it is wiring or electrical and help you troubleshoot fuel problems. Come back here and ask if you have any questions. Quote Selected
1988 thunderbird v6 problems Reply #4 – May 28, 2016, 09:30:44 AM OK so new fuel filter didn't do anything I think I can here the fuel pump hum when I turn the key I for sure here the relays click then a hum also I couldn't get the starter fluid to do anything idk if I'm too slow or what Quote Selected

1988 thunderbird v6 problems Reply #6 – May 28, 2016, 01:36:20 PM The injectors will not fire if you have no spark.http://sbftech.com/index.php?topic=588.0Again, this will tell you exactly what is wrong. It takes 10-20 minutes and all you need is a volt meter or test light and a few basic tools. Quote Selected
1988 thunderbird v6 problems Reply #7 – May 29, 2016, 07:56:58 PM Test said to check a yellow or tan wire at the coil I don't have one?? I have a green and a red and both light up the tester hooked to the - post there is a transistor that is taped up also idk if that has anything to do I was able to get signals from all the icm posts so far all I can think it is is the icm coil or pip Quote Selected
1988 thunderbird v6 problems Reply #8 – May 30, 2016, 03:55:09 AM Did you test the spark by rotating the dist?Essentially, the computer can only "see" when the #1 cylinder fires and uses that signal to sequentially fire all the other injectors. All the pip does is marks that #1 notch. The tfi module is basically the timing computer that takes additional load off of the computer calculating the signal.When you rotate the dist back and forth you should get a distinctive click. That click is the pip detecting movement and the computer firing an injector. If you can, unplug or back probe an injector and rotate the dist back and forth. If you aren't getting any light, either the pip or tfi module is bad or you have a wiring issue inbetween.I have had exactly one aftermarket tfi module die on me, I have never had a factory one die. They usually get weak before they completely fail and heat up quickly. Most good autoparts stores can test the tfi module but a pip often needs either disassembly of the dist for replacement or a whole new dist. I usually hit a junkyard and try to find a wrecked car and use that dist for a dead to nuts verification that it was the problem.There are ways to generally test the tfi and pip, but if one is bad, I would replace both.

1988 thunderbird v6 problems Reply #10 – May 30, 2016, 10:54:29 AM I did all the tests everything passed so then it would be the stator or tfi. I can here and injector clicking Quote Selected
1988 thunderbird v6 problems Reply #11 – May 30, 2016, 11:15:00 AM OK so it passed all the test which leaves me with the stator and the tfi. Ik where the tfi is but I'm not sure about the stator. I put a new ignition coil on and it started and ran fine I even shut it off and started it again but I came but 10 minutes later and no start again Quote Selected
1988 thunderbird v6 problems Reply #12 – May 30, 2016, 03:14:37 PM Usually points to tfi or pip. As they heat up they fail. Stator is another name for the pip. It's got the small wire hooked up inside the dist under everything. Usually the whole dist needs to come apart to replace it. Quote Selected

1988 thunderbird v6 problems Reply #14 – May 31, 2016, 06:05:04 PM Well new icm new ignition coil new distributor still no spark. It sounds like it's starting when you turn key off after trying to start it? Quote Selected
