CarrieJT Posted September 22, 2022 Share Posted September 22, 2022 My 1988 Reatta is finally home and it's been so long I've forgotten most of my knowledge. Hoping someone here can help. I have shop manuals but I don't speak that language too well. No interior lights for anything anywhere, no normal clicking and whirring buzz...and no fuel pump sound. I got battery on and engine will run with carb cleaner sprayed into intake. I swapped steering columns and was able to start with key (long story between ex and thieves). The heater, a.c., CRT, etc was not working nor was dash lights, before I parked it in 2015. But could still drive it. Any ideas? I don't see any rat chewed wires or loose connections. I'm thinking a bad relay or blown inline fuse, or I'm missing something maybe? Help is much appreciated... This was my favorite car ever made. I have an extra for parts so I'm ready to learn/get going again! TIA! Link to comment Share on other sites More sharing options...
rogold99 Posted September 22, 2022 Share Posted September 22, 2022 (edited) Try checking all of these connections in the diagram for corrosion or being loose. Look at the fuseable links to make sure one of them isn't burned up. https://reattaowner.com/roj/component/content/article/index.php?option=com_content&view=article&catid=62:other-electrical&id=224:ground-terminals-junction-box-location Edited September 22, 2022 by rogold99 (see edit history) 1 Link to comment Share on other sites More sharing options...
rogold99 Posted September 22, 2022 Share Posted September 22, 2022 Try this to test the fuel pump https://reattaowner.com/roj/component/content/article/index.php?option=com_content&view=article&catid=67:fuel-system&id=244:fuel-pump-troubleshooting If you think the fuel pump relay is bad, you could swap it with one of the other relays next to it temporarily https://reattaowner.com/roj/component/content/article/index.php?option=com_content&view=article&catid=67:fuel-system&id=277:fuel-pump-relay-location 1 Link to comment Share on other sites More sharing options...
2seater Posted September 22, 2022 Share Posted September 22, 2022 To check the fuel pump activation directly, check for voltage on the green connector which is somewhere near the brake master under the hood. It is a bare female spade. Should have voltage for a few seconds when the key is turned to run. Alternately, apply 12v+ to the connector which will activate the pump if it is capable of running 1 Link to comment Share on other sites More sharing options...

Everything worked when it went into storage, but when I got it no chimes, touch screen illumination or buttonsworking on the touch screen. Swapped out the PCM [Power Control Module] and everything came back. I did check the fuses but that wasn't it. 1 Link to comment Share on other sites More sharing options...
CarrieJT Posted September 23, 2022 Author Share Posted September 23, 2022 Where is that located? Behind glove box? I have a complete parts car. Do you know if fuel pump power goes thru there? Man I really don't wanna change it, but he fuel pump... Lol. Link to comment Share on other sites More sharing options...
Barney Eaton Posted September 23, 2022 Share Posted September 23, 2022 You should get the old fuel out even if the pump does not need replacing. 1 Link to comment Share on other sites More sharing options...

The neighbors had already relieved me of all fuel and my catalytic converter... 🙄 So no problem with the gas except what was still in the lines. I'll drain out the 3gal I put in though, good idea Link to comment Share on other sites More sharing options...

Also the 110inverter in the dash I think I'll swap it... Link to comment Share on other sites More sharing options...

I can get it to run if someone sprays carb cleaner into intake. I was sure glad to hear it run...although it sounded like my motorcycle...neighbor had cut off the cat conv...

I got connectors today so I'm going to swap out the relay terminal for fuel pump. It's just greasy nasty but seems functional. I checked the pins and also swapped relays. Same result...no fuel pump. I wonder about the wires actually under the car to the pump? Which side are they on? Maybe a rat chewed it or they cut it when removing my cat conv???

Barney Eaton Posted September 26, 2022 Share Posted September 26, 2022 With the key ON..... see if you have 12v at the gas tank Link to comment Share on other sites More sharing options...
2seater Posted September 26, 2022 Share Posted September 26, 2022 To my knowledge, there is no wiring under the car, it all is inside the body. There is a plug at the tank which is accessible with the tank in place Link to comment Share on other sites More sharing options...
